WHATILEARNEDBYWALKING
300MILESLASTSUMMER…
After two years of planning I embarked last July on a 300-mile walk across the top of
Spain called the Camino de Santiago or the Way of St. James. The Way of St. James was
one of the most important Christian pilgrimages during the Middle Ages along with
Rome and Jerusalem. Some of you may have seen the movie called “The Way” starring
Martin Sheen…if not it’s a good movie to watch sometime.
Some do the walk for religious reasons but I went to get away from everything and
get some space to think about what I wanted to do next in my life and instead I learned
two important lessons.
Thefirstdayofthejourney,IbeganontheborderwithFranceandIrememberthink-
ing to myself, “why did I sign up for a 300 mile walk?” It’s funny but I am not a person
who walks a lot. I had doubts probably like everyone else waking up on the border that
day, but it’s really about breaking it down to digestible portions. The important thing is
to have a long term goal and always be making progress, however small the progress it.
The biggest lesson I learned is “keep it simple.” Our lives in 2015 are so complicated
and it seems to be getting more complicated over time. The good news is you need less
than you think. We live in an age of smartphones, smart watches, computers, and lots
of other distracting beeping devices that we respond to like Pavlov’s dog. The constant
distractionsinterruptyourmomentumandmakeitdifficulttocompletecomplextasks.
The camino reminded me to enjoy technology but not to let it run my life. Sounds sim-
pleasIseeeveryoneontheirdevices“beingconnected”,butkeepingitsimpleallowsme
to focus on the things that really matter.
Keep it simple and always work towards your goals. And if you’re curious about the
Camino feel free to contact me.

Bench
AGood
BY VIRGINIA BURT
PHOTOS COURTESY VIRGINIA BURT
“Somewhere in every garden, there must be
at least one spot, a quiet garden seat, in which a
person – or two people – can reach into themselves
and be in touch with nothing else but nature.”
– Christopher Alexander
S
omewhere in ev-
ery garden, there
must be that
perfect bench, as
Christopher Al-
exander so aptly
puts it in his
1977 classic ref-
erence, A Pattern
Language. That
“quiet garden
seat” will be most used, in my experi-
ence, when it is located within a spatial
landscape archetype known as “Harbour”.
The Harbour, one of seven landscape
archetypes described by Julie Messervy in
The Inward Garden (1996), is common to
all healing gardens and in fact to all good
garden design, whether for people who
are healthy or those who are ill. Messervy
defines the harbour as “a haven, an em-
bracing space, a space of enclosure, a safe
refuge for body and soul.”
A bench within a Harbour feels safe,
offering just enough privacy, yet remain-
ing a part of the path or garden in which
it sits. A Good Bench is usually set just
off the main path, where it takes in the

view of a beautiful rock or a sculpture or
a distant point. It may even be shaped in
a semicircle, feeling like a literal harbour
embracing those who sit there.
Ideally, if we create a place where
people will sit longer, they are apt to
receive more of Nature’s inherent bene-
fits. Across the world’s cultures, “sitting
meditation is the universal posture used
for accessing the human resource of wis-
dom,” writes Angeles Arrien in The Four
Fold Way.
THE SEAT
Good benches share several qualities.
First, consider the seat itself including its
comfort, materiality, and orientation to
climate. Author Dr. John-Roger says “the
amount the brain can take in, is as much
as the butt is comfortable.” Yet too often
in gardens for healthcare settings, one
comes upon the ubiquitous white plastic
chair overturned in a snowbank.
Benches (or chairs) must be ergonom-
ically designed, with backs and armrests.
Assign a worthy budget for quality out-
door furniture. This will assist in creating
visual coherence, and make the garden
inviting. Sitting is ideally an invitation,
rather than a navigation.
Materiality becomes a multifaceted
decision. Natural materials are always
preferable due to our human biophilic
tendencies. Ideally, the bench materials
will be neutral with respect to ambient
temperature absorption (neither too hot
nor too cold). The material must also
be well draining and relatively easy to
maintain.
Orientation, particularly in our Canadi-
an climate, generally means facing south
for warming sun exposure in winter, and
providing shade in summer. In my own
garden, seats face one another across an
open expanse of lawn (hiding the septic
field beneath). In summer, the north
facing bench is shaded all morning by the
tall hedge beyond; the south facing bench
is shaded all afternoon. The opposite is
true in winter.
A QUIET BACK
Creation of a quiet back is the second
ingredient of a Good Bench. “Small spaces
succeed by providing a sense of enclosure”
(Kaplan, p.119). So often, people search for
places to confront a poor prognosis or to
comfort a loved one, or just to be alone.
Privacy is often overlooked.
On a bench that offers effective enclo-
sure, we are able to track the area beyond,
yet feel safely tucked within. This is more
fully described in a new book by Clare
Cooper Marcus and Naomi Sachs, Ther-
apeutic Landscapes: An Evidence-Based
Approach to Designing Healing Gardens
and Restorative Outdoor Spaces, which
explores Jay Appleton’s prospect and
refuge theory. His theory postulates that
“the ability to see with a clear view (pros-
pect) from a safe vantage point without
being seen (refuge) and without potential
danger (hazard) is most comfortable and
thus most preferred.” A Good Bench
should have a quiet back, perhaps formed
by a wall, shrubs approximately three feet
high, a thick tree trunk, or evergreens.
SOMETHING TO LOOK AT…
Third, a Good Bench offers something
to look at. Christopher Alexander, again,

ccording to a recent ASLA
report, Fire pits/Fireplaces
were ranked the highest
in expected popularity
for 2015 desired outdoor
design elements. Landscape architects
are anticipated to receive an increase
in fire pit installation requests, ASLA
notes. “Consumers care about designed
landscapes that are attractive, easy to
take of and eco-friendly,” states Nancy
Sommerville, executive vice president
and CEO of ASLA.* Fire pits are cer-
tainly an attractive landscape design
feature and give residents an atmosphere
suited for family gatherings and outdoor
entertainment. There are three different
types of fire pits available to consumers:
traditional wood-burning, natural gas, or
propane-liquid. There are some things to
consider when presenting these options
to your buyers. With liquid propane, it is
important to note that it offers buyers a
portable option. Natural gas fire pits can
be cheaper if your buyer expects to use it
often, by connecting it to the house’s gas
line.
When comparing traditional wood-
burning fire pits to gas, consumers might
be surprised to discover the benefits of
using gas fire pits. Although it is obvious
they don’t have a smell or smoke, this
can be a very important selling feature
for people with respiratory issues. They
are also much easier to maintain and
install, saving you labor costs. As Nancy
Sommerville notes, consumers like easy
maintenance and eco-friendly options
which gas fire pits fulfill. From an aes-
thetic point of view, gas fireplaces offer
more design options for the upscale buyer
and high-end user. For a more traditional
design, consider using artificial log sets.
For modern designs, using lava media,
volcanic stones, fire glass, gems, or nug-
gets works great for gas fire pits.
Here are some tips for installing a gas
fire pit:
■■ Install on a level surface away from
flammable material
■■ Consult the fire pit manufacturer’s
installation guide for specific minimum
distance requirements
■■ Always turn off gas supply before
installation
■■ Observe local gas codes before
hooking it to house’s gas line when using
natural gas or even for liquid propane
■■ Place the holes down to avoid clog-
ging of the pipes due to weather
■■ Always check for gas leaks after
installation
■■ For annual service, ensure the con-
trol compartment, burners and circulat-
ing air passageways of the fire pit are kept
clean.
■■ When adding lava or glass media, it
is best not to exceed ½” above burner.
■■ When adding volcanic stone or log
sets, it is best to use lava granules as a base
(not higher than ½” above burner).
	
It is important to educate your buy-
ers with simple steps they can take to
maintain their fire pit. They should
always wipe away any brush or flammable
material. Stones and pavers will eventual-
ly erode so it is necessary to protect them
with a thin coating of sealant. Applying
a thick layer causes bubbling thereby
reducing the effectiveness of the sealant.
HISCO carries many types of sealants
for different stone or granite material. To
avoid weather damage, consumers should
cover their fire pit with a waterproof vinyl
tarp. Keeping your consumers informed
will make it easier for you upon annual
servicing. Visit your local HISCO to get all
the materials you need to install a fire pit
at your next job!

munity for over 40 years, providing the best

“Often people get trapped
in a color palate. Pottery
allows us to break out
of the trappings of a
monotone canvas”
I
n Hawaii’s sub-tropics, we’re
surrounded by natural beauty and
color. Our landscape designs are
often expressions and celebrations
of these surroundings. One factor
that can make or break a landscape set-
ting is color balance.
Pottery is an ultra simple and inexpen-
sive way to bring the color palette of any
landscape project to the next level. Just
one piece can transform ordinary into
extraordinary — from conservative rustic
earth tone to bold splashes of color.
“When you’re furnishing a landscape,
pottery is an excellent way to enhance
the attractiveness and livability of any
project,” says Randall Monaghan of
Monaghan Landscape Architects.
Key placement of pottery can add
richness and variation to a hardscape ele-
ment, as well as color in a bed of vegeta-
tive green. Pieces comes in array of styles
and colors — blue, green, red, orange,
yellow, silver, black and more — allowing
the homeowner or client to match colors
that express their personal tastes.
“Often people get trapped in a color
palate. Pottery allows us to break out of
the trappings of a monotone canvas,” says
Geobunga owner Andrew Dedrick.
Examples of well-placed pottery can be
seen across the state, from private homes
on the Kona Coast to shopping centers in
Poipu to everywhere else in between.
Andrew Dedrick is the Executive Director
of Geobunga.

TIPS
TOOL
M
ake no mistake all hedges
are not created equal. In
Hawaii, where lot sizes
are smaller and creating
a perimeter boundary to
delineate property lines and/or spaces, and
create additional privacy, hedges seem to
be the ideal solution. Not only can they add
color and texture, they are sometimes a dec-
orative element to break-up a monotonous,
flat space. Many different plants can be used
for hedges, and the height of the hedge can
vary according to its purpose. In some situ-
ations, the height is specified in the contract
(or scope of work), in others, it is the aes-
thetic that dictates the appearance (height
and width). No matter what the situation,
hedges, like all plants, need to be maintained
on a regular basis. Often the time between
trimming is determined by the amount of
sunlight and the amount of water.
The tool of choice the: HEDGE TRIM-
MER. The hedge trimmer is more than a
line trimmer with a different cutter head.
Here are some truths common to all
hedge trimmers. Hedge trimmers come
in a variety of styles and lengths (We will
be discussing commercial, gas powered
trimmers; not corded electric units which
have shorter blades, and cost a fraction of
the commercial units.) In general, hedge
trimmers are more expensive than line
trimmers, averaging between $400.00 to
$550.00. There are more parts to maintain,
even though it is used less often than a line
trimmer.
Before purchasing a hedge trimmer,
identify the height of the hedge and the
size of the branches you will be trimming.
Remember you will not be buying a hedge
trimmer every year, so you need to antic-
ipate the rate of growth of the plant and
know how tall and wide you want the
hedge.
There are size limits to the cutting
capacity of the trimmer, but the specs may
not apply to the type of plant that you will
be cutting. You need to know if you will
only be cutting new growth, or cutting
back 12” on an old mockorange hedge. If
the hedge is old, and woody, the hedge
trimmer may not be the appropriate tool.
(You may do better with a small chain saw
to cut through the woody branches.) Most
commercial hedge trimmers say that they
will cut between one half to three quarters
of an inch. This number is approximate and
based on the plant material AND sharpness
of the blades.
The additional cost of hedge trimmers is
related to 1) The cutter gear case, and 2) The
hardened steel of the blades. The cutter
gear case is like an additional machine,
it is the part that makes the blades move
back and forth. It is made up of a cam gear,
connecting rods and
bearings. Most have
a grease fitting which
enables greasing on a regular
basis. When the blades are
“forced” from cutting things that
are too hard and/or too big – 1) the
gear case internal parts will jam and break,
and the cutter blades will not work; and/or
2) the blades will become damaged and will
need to be replaced. (Do not use the hedge
trimmer if the blades are broken.) In order
to replace the blades, the gear case will need
to be opened up, and parts replaced.
HAND-HELD, EXTENDED REACH.
SINGLE/DOUBLE SIDED. Hedge trimmer
generally need to cut horizontally (the top
of the hedge) and vertically (the sides of the
hedge). Know the height and width of the
hedge that you will be cutting. For hedges
that can be reached while standing on the
ground, the hand held (24”, 30”, 40”) is
usually the trimmer of choice. Single sided
trimmers are usually 30” or 40”. With these
trimmers you can only cut in one direction.
The double-sided trimmer allows you to
cut in both directions, but usually comes
in shorter lengths. In either case, operators
should wear protective leg gear to prevent
injuries. There are some safety videos for
non-believers about the dangers when
using hedge trimmers.
For taller hedges, rather than using a
ladder, consider either a short shaft (half
the length of a line trimmer shaft) or an
extended reach hedge trimmer (the same
length shaft as a hedge trimmer). The
extended reach comes with an articulating
cutter head allowing the operator to cut
the horizontal portion of a tall hedge while
standing on the ground.
No matter which style of hedge trim-
mer you have, BLADES NEED TO BE
SHARPENED to get a clean, crisp cut. The

bolts and nuts holding the
blades together need to be
checked and adjusted. If the
bolts are too loose, the blades
will not meet properly; if they
are too tight, the blades will not
move.
I recently spoke with a grounds supervi-
sor who had several hedge trimmers which
were not working. I asked him if he thought
that this was a coincidence. I suggested that
he examine what they were trying to cut, or
the way that the operators were using the
machine, before he bought a new machine.
It was like a light went on—he hadn’t
thought about that.
Get the right tool for the job.

is frank: “Where outdoor seats are set
down without regard for view...they will
almost certainly be useless,” he writes. To
help create a meditative space, particu-
larly in healing gardens, provide a natural
distraction, also known as a ‘fascination’.
There are so many to choose from, from
sculptures to aspects of nature aptly
described by Kaplan, Kaplan and Ryan, in
With People In Mind. “Nature is well en-
dowed with objects of fascination in flora,
fauna, water and the endless play of light.”
In my experience, these ingredients
will create wonderful places to sit. I spoke
one day to a cancer survivor, who was
sitting on a carved bench custom made
to fit most garden visitors perfectly – a
Good Bench that has a quiet back formed
by a curving wall, and offers a view of
low plantings and spruces, with a lovely
church window and tower beyond. “I
have been treated twice for cancer at Uni-
versity Hospitals in the past seven years
and today I am a happily, healthy person
who rarely thinks of myself as a cancer
survivor,” she said. “As I … sat quietly by
myself on one of the rocks that creates a
private space at the back of the garden,
a wave of emotion washed over me that
was completely unexpected.”
These unexpected moments are so
often due to the salutogenic design of a
good bench – design that encourages use,
vitality, health and wellness.

P
esticide products on the
market contain more than just
active ingredients. They con-
tain other ingredients added
by manufacturers to stabilize
the product and protect its performance.
Glycol may be included in water-based
formulations, for example, to stabilize
them during a freeze-thaw cycle. Glycol
won’t keep the pesticide from freezing,
but will protect it from degrading when
the product thaws. There may be addi-
tives to thicken a formulation or stabilize
chemicals. Surfactants or other adjuvants
may also be included in pesticides to
improve their function.
The addition of adjuvants to pesticide
products by the manufacturer, however,
has disadvantages. An adjuvant that is
compatible with the active ingredient
under dilute conditions may be incom-
patible in the concentrated product.
Similarly, an organosilicone surfactant
may be stable in a spray tank, but unstable
on a shelf after several years.
The active ingredient, or ingredients, is
the most valuable component of the pes-
ticide product. Therefore, manufacturers
strive to present the most effective prod-
uct in a stable, easy to use formulation.
Adding adjuvants, however, increases the
cost of the product and may make it less
competitive on the market.
Manufacturers have several reasons
to leave the addition of adjuvants to the
applicator. Therefore, applicators must
consider a number of factors when pre-
paring a spray mixture.
■■ Local water quality features, such
	 as pH and hardness.
■■ Final volume of the spray. The
	 amount of adjuvant is usually
	 calculated on a volume-to-volume
	 rate and the manufacturer cannot
	 know the requirements of the
	 individual applicator.
■■ Local differences in the
	 target pest. A pest may be
	 more difficult to control
	 in some areas and
	 require more or less
	 of an adjuvant. Timing
	 and crop tolerance
	 also need to be considered.
■■ Local or regional weather
	 conditions that may influ
	 ence the amount of adjuvant need
	 ed. In hot, dry weather for example,
	 humectants (evaporation retardants)
	 and drift retardants may be needed.
	 They usually are unnecessary in
	 wetter, more humid climates, how
	 ever, and adding them would be an
	 unnecessary expense for the manu
	facturer.

The pesticide label gives the applica-
tor information developed over years of
testing by the manufacturer. This infor-
mation may include: a specific recom-
mendation to use an adjuvant, whether
adjuvants are prohibited, or provide no
information about an adjuvant.
Adjuvants
“Unless specific tank mix directions
are given in Corn Use Directions, always
use a methylated seed oil (MSO) or a pe-
troleum-based vegetable seedbased oil
concentrate (COC) with [product name].”
—from the “Additives”
section of an herbicide label
Labels Prohibiting
Specific Adjuvants
Sometimes pesticide labels will state
that the use of an adjuvant is unnecessary,
will make the pesticide less effective, or
may injure the crop. If spray drift control
is a component of a new pesticide, man-
ufacturers may warn that adding other
adjuvants may
increase
drift.
Though the applicator takes full
responsibility for possible unintended
consequences, the use of adjuvants can
produce excellent results. The decision is
assisted by knowing the following:
■■ Set-up of the sprayer
■■ Properties of the water in the tank
	mix
■■ Main pests being targeted
■■ Rate of pesticide and volume of
	 water used
■■ Environmental conditions.
■■ Previous experience with the
	 pesticide and adjuvant.
Spray Drift
“The best drift management strategy
and most effective way to reduce drift
potential is to apply large droplets that
provide sufficient coverage and control.
Applying larger droplets reduces drift
potential but will not prevent drift if ap-
plications are made improperly or under
unfavorable environmental conditions.”
—from the “Managing Off-Target Mo
Pesticide labels may describe condi-
tions that suggest a type of adjuvant may
Labels on some adjuvant products may
warn users as follows:
■■ “High relative humidity may in
	 crease the risk of temporary discol
	 oration. Use of surfactants is not
	recommended.”
■■ “Use only nonionic surfactant on
	 ornamentals. Do not use a crop
	 oil concentrate with [product name]
	 on ornamentals.”
■■ “Do not add surfactants, additives
	 containing surfactants, buffering
	 agents, or pH-adjusting agents to
	 the spray solution when [product
	 name] is the only pesticide used.”
■■ “Certain spray tank additives (adju
	 vants, wetting agents, surfactants),
	 liquid fertilizers, and tank mixtures
	 containing emulsifiable concen
	 trates may reduce the selectivity on
	 turfgrass. Use adjuvants and spray
	 additives or tankmix combinations
	 only when your experience indicates
	 that the tank mixture will not result
	 in objectionable turf injury.”
If adjuvants are already included in
a pesticide product, adding more may
be unnecessary, reduce effective-
ness, or cause crop damage. For
example, adding a surfactant
to a fast-acting herbicide can
increase the risk of injury to
the crop. The label of one
herbicide has the follow-
ing warning: “Temporary
discoloration of some turf
types may result from use
of surfactants or adjuvants
with [product name].
High temperatures and
high relative humidity
may increase the risk of
temporary discoloration.
Use of surfactants is not
recommended.”
be effective. For example, it may state
that when applying the pesticide in low
relative humidity the equipment should
be adjusted to produce larger spray drop-
lets. You may be able to accomplish this,
however, by using a humectant to keep
smaller droplets from evaporating. Or you
might use a deposition or retention (drift
suppressing) agent that would increase
the overall size of the droplets.
Representatives from pesticide manu-
facturers, consultants, local crop advisors,
or university extension agents may offer
important advice. They not only have the
When Labels Say Nothing
About Adjuvants
The manufacturer may not recommend
or prohibit the use of adjuvants to its
product. If the label does not prohibit the
addition of an adjuvant, it is not against
state or federal law to do so. Pesticide
products are often formulated for various
types of applications and some situations
may require adjuvants when others do
not.
Tank Mixes
“If this product is used in combina-
tion with any other product except as
specifically
recommended in writing by [the man-
ufacturer] then [the manufacturer] shall
have no liability for any loss, damage, or
injury arising out of its use in any such
combination not so specifically recom-
mended.”
—from the “Uses With Other
Products” section of an herbicide label
There is a wide range of adjuvants
on the market and they are constantly
changing. Pesticide manufacturers cannot
test them all. Changing the pesticide
label is also time-consuming and must
be approved by the U.S. Environmental
Protection Agency.
Therefore, manufacturers may only
make general recommendations on
their labels, to give more flexibility of
use to the consumer and not to discour-
age the makers of adjuvants from devel-
oping new products.
If an adjuvant is not recommended on
the pesticide label, however, the responsi-
bility for its use is the applicator’s alone.
The manufacturer of the adjuvant may
specify on their label that the surfactant
“is recommended for use with those pesti-
cides whose label recommends a non-
ionic wetter/spreader-type adjuvant,” or
“Always refer to the label on the product
before using [name of adjuvant product]
or any other product.”

has been done with the pesticide product
or adjuvant for a specific pest and on a
particular crop.

nificant floricultural crop
with average annual sales
of flowers in the State of
over $500K per year, primarily for the
lei industry. In 1991, Plumeria rust leaf
disease became established on Oahu and
quickly spread throughout the State. It is
easily recognized by its yellow spots on
the leaves with yellow-orange powdery
spore masses on the underside of leaves.
Most Plumeria cultivars grown in Hawaii
are susceptible.
Plumeria rust is caused by the fungus
Coleosporium plumeriae. The pathogen
infects only the leaves, not the stems or
flowers. When leaves are severely dis-
eased, they may dry, curl, become distort-
ed, and drop from the tree. Total defolia-
tion of the tree may occur. The disease is
more of a problem in warm, moist areas.
While treatment with listed fungicides
such as Eagle (40 WP or 20EW) with
an active ingredient of mycobutanil or
Heritage with an active ingredient of
azoxystrobin is possible, planting resis-
tant species or hybrids is a better option.
Plumeria stenopetala and Plumeria
caracasana have been found to be highly
resistant to this disease. Growing Plume-
rias in drier areas with wider spacings
to enhance airflow also helps to reduce
infestations of Plumeria rust, as does
avoiding monocultures. Picking up and
destroying fallen leaves may also help
since these are a source of spores. Some
biological control agents of Plumeria rust
have been reported, including fungal hy-
perparasites and a midge insect predator.
Spraying fungicides or insecticides may
disrupt the life cycles of these biological
control agents.

The Way of St. James was one of the most important Christian pilgrimages during the Middle Ages along with Rome and Jerusalem. Some of you may have seen the movie called “The Way” starring Martin Sheen…if not it’s a good movie to watch sometime. Some do the walk for religious reasons but I went to get away from everything and get some space to think about what I wanted to do next in my life and instead I learned two important lessons. Thefirstdayofthejourney,IbeganontheborderwithFranceandIrememberthink- ing to myself, “why did I sign up for a 300 mile walk?” It’s funny but I am not a person who walks a lot. I had doubts probably like everyone else waking up on the border that day, but it’s really about breaking it down to digestible portions. The important thing is to have a long term goal and always be making progress, however small the progress it. The biggest lesson I learned is “keep it simple.” Our lives in 2015 are so complicated and it seems to be getting more complicated over time. The good news is you need less than you think. We live in an age of smartphones, smart watches, computers, and lots of other distracting beeping devices that we respond to like Pavlov’s dog. The constant distractionsinterruptyourmomentumandmakeitdifficulttocompletecomplextasks. The camino reminded me to enjoy technology but not to let it run my life. Sounds sim- pleasIseeeveryoneontheirdevices“beingconnected”,butkeepingitsimpleallowsme to focus on the things that really matter. Keep it simple and always work towards your goals.

That “quiet garden seat” will be most used, in my experi- ence, when it is located within a spatial landscape archetype known as “Harbour”. The Harbour, one of seven landscape archetypes described by Julie Messervy in The Inward Garden (1996), is common to all healing gardens and in fact to all good garden design, whether for people who are healthy or those who are ill. Messervy defines the harbour as “a haven, an em- bracing space, a space of enclosure, a safe refuge for body and soul.” A bench within a Harbour feels safe, offering just enough privacy, yet remain- ing a part of the path or garden in which it sits. A Good Bench is usually set just off the main path, where it takes in the

It may even be shaped in a semicircle, feeling like a literal harbour embracing those who sit there. Ideally, if we create a place where people will sit longer, they are apt to receive more of Nature’s inherent bene- fits. Across the world’s cultures, “sitting meditation is the universal posture used for accessing the human resource of wis- dom,” writes Angeles Arrien in The Four Fold Way. THE SEAT Good benches share several qualities. First, consider the seat itself including its comfort, materiality, and orientation to climate. Author Dr. John-Roger says “the amount the brain can take in, is as much as the butt is comfortable.” Yet too often in gardens for healthcare settings, one comes upon the ubiquitous white plastic chair overturned in a snowbank. Benches (or chairs) must be ergonom- ically designed, with backs and armrests. Assign a worthy budget for quality out- door furniture. This will assist in creating visual coherence, and make the garden inviting. Sitting is ideally an invitation, rather than a navigation. Materiality becomes a multifaceted decision. Natural materials are always preferable due to our human biophilic tendencies. Ideally, the bench materials will be neutral with respect to ambient temperature absorption (neither too hot nor too cold). The material must also be well draining and relatively easy to maintain. Orientation, particularly in our Canadi- an climate, generally means facing south for warming sun exposure in winter, and providing shade in summer. In my own garden, seats face one another across an open expanse of lawn (hiding the septic field beneath). In summer, the north facing bench is shaded all morning by the tall hedge beyond; the south facing bench is shaded all afternoon. The opposite is true in winter. A QUIET BACK Creation of a quiet back is the second ingredient of a Good Bench. “Small spaces succeed by providing a sense of enclosure” (Kaplan, p.119). So often, people search for places to confront a poor prognosis or to comfort a loved one, or just to be alone. Privacy is often overlooked. On a bench that offers effective enclo- sure, we are able to track the area beyond, yet feel safely tucked within. This is more fully described in a new book by Clare Cooper Marcus and Naomi Sachs, Ther- apeutic Landscapes: An Evidence-Based Approach to Designing Healing Gardens and Restorative Outdoor Spaces, which explores Jay Appleton’s prospect and refuge theory. His theory postulates that “the ability to see with a clear view (pros- pect) from a safe vantage point without being seen (refuge) and without potential danger (hazard) is most comfortable and thus most preferred.” A Good Bench should have a quiet back, perhaps formed by a wall, shrubs approximately three feet high, a thick tree trunk, or evergreens. SOMETHING TO LOOK AT… Third, a Good Bench offers something to look at. Christopher Alexander, again, continued on page 25
  • 8. HAWAIISCAPE.COM 1514 LANDSCAPE HAWAII JULY | AUGUST 2015 For Information call: 808-677-1580 or visit www.tensarnagreen.com A ccording to a recent ASLA report, Fire pits/Fireplaces were ranked the highest in expected popularity for 2015 desired outdoor design elements. Landscape architects are anticipated to receive an increase in fire pit installation requests, ASLA notes. “Consumers care about designed landscapes that are attractive, easy to take of and eco-friendly,” states Nancy Sommerville, executive vice president and CEO of ASLA.* Fire pits are cer- tainly an attractive landscape design feature and give residents an atmosphere suited for family gatherings and outdoor entertainment. There are three different types of fire pits available to consumers: traditional wood-burning, natural gas, or propane-liquid. There are some things to consider when presenting these options to your buyers. With liquid propane, it is important to note that it offers buyers a portable option. Natural gas fire pits can be cheaper if your buyer expects to use it often, by connecting it to the house’s gas line. When comparing traditional wood- burning fire pits to gas, consumers might be surprised to discover the benefits of using gas fire pits. Although it is obvious they don’t have a smell or smoke, this can be a very important selling feature for people with respiratory issues. They are also much easier to maintain and install, saving you labor costs. As Nancy Sommerville notes, consumers like easy maintenance and eco-friendly options which gas fire pits fulfill. From an aes- thetic point of view, gas fireplaces offer more design options for the upscale buyer and high-end user. For a more traditional design, consider using artificial log sets. For modern designs, using lava media, volcanic stones, fire glass, gems, or nug- gets works great for gas fire pits. Here are some tips for installing a gas fire pit: ■■ Install on a level surface away from flammable material ■■ Consult the fire pit manufacturer’s installation guide for specific minimum distance requirements ■■ Always turn off gas supply before installation ■■ Observe local gas codes before hooking it to house’s gas line when using natural gas or even for liquid propane ■■ Place the holes down to avoid clog- ging of the pipes due to weather ■■ Always check for gas leaks after installation ■■ For annual service, ensure the con- trol compartment, burners and circulat- ing air passageways of the fire pit are kept clean. ■■ When adding lava or glass media, it is best not to exceed ½” above burner. ■■ When adding volcanic stone or log sets, it is best to use lava granules as a base (not higher than ½” above burner). It is important to educate your buy- ers with simple steps they can take to maintain their fire pit. They should always wipe away any brush or flammable material. Stones and pavers will eventual- ly erode so it is necessary to protect them with a thin coating of sealant. Applying a thick layer causes bubbling thereby reducing the effectiveness of the sealant. HISCO carries many types of sealants for different stone or granite material. To avoid weather damage, consumers should cover their fire pit with a waterproof vinyl tarp. Keeping your consumers informed will make it easier for you upon annual servicing. Visit your local HISCO to get all the materials you need to install a fire pit at your next job!

Pottery allows us to break out of the trappings of a monotone canvas” I n Hawaii’s sub-tropics, we’re surrounded by natural beauty and color. Our landscape designs are often expressions and celebrations of these surroundings. One factor that can make or break a landscape set- ting is color balance. Pottery is an ultra simple and inexpen- sive way to bring the color palette of any landscape project to the next level. Just one piece can transform ordinary into extraordinary — from conservative rustic earth tone to bold splashes of color. “When you’re furnishing a landscape, pottery is an excellent way to enhance the attractiveness and livability of any project,” says Randall Monaghan of Monaghan Landscape Architects. Key placement of pottery can add richness and variation to a hardscape ele- ment, as well as color in a bed of vegeta- tive green. Pieces comes in array of styles and colors — blue, green, red, orange, yellow, silver, black and more — allowing the homeowner or client to match colors that express their personal tastes. “Often people get trapped in a color palate. Pottery allows us to break out of the trappings of a monotone canvas,” says Geobunga owner Andrew Dedrick. Examples of well-placed pottery can be seen across the state, from private homes on the Kona Coast to shopping centers in Poipu to everywhere else in between. Andrew Dedrick is the Executive Director of Geobunga.

BY PHYLLIS JONES TIPS TOOL M ake no mistake all hedges are not created equal. In Hawaii, where lot sizes are smaller and creating a perimeter boundary to delineate property lines and/or spaces, and create additional privacy, hedges seem to be the ideal solution. Not only can they add color and texture, they are sometimes a dec- orative element to break-up a monotonous, flat space. Many different plants can be used for hedges, and the height of the hedge can vary according to its purpose. In some situ- ations, the height is specified in the contract (or scope of work), in others, it is the aes- thetic that dictates the appearance (height and width). No matter what the situation, hedges, like all plants, need to be maintained on a regular basis. Often the time between trimming is determined by the amount of sunlight and the amount of water. The tool of choice the: HEDGE TRIM- MER. The hedge trimmer is more than a line trimmer with a different cutter head. Here are some truths common to all hedge trimmers. Hedge trimmers come in a variety of styles and lengths (We will be discussing commercial, gas powered trimmers; not corded electric units which have shorter blades, and cost a fraction of the commercial units.) In general, hedge trimmers are more expensive than line trimmers, averaging between $400.00 to $550.00. There are more parts to maintain, even though it is used less often than a line trimmer. Before purchasing a hedge trimmer, identify the height of the hedge and the size of the branches you will be trimming. Remember you will not be buying a hedge trimmer every year, so you need to antic- ipate the rate of growth of the plant and know how tall and wide you want the hedge. There are size limits to the cutting capacity of the trimmer, but the specs may not apply to the type of plant that you will be cutting. You need to know if you will only be cutting new growth, or cutting back 12” on an old mockorange hedge. If the hedge is old, and woody, the hedge trimmer may not be the appropriate tool. (You may do better with a small chain saw to cut through the woody branches.) Most commercial hedge trimmers say that they will cut between one half to three quarters of an inch. This number is approximate and based on the plant material AND sharpness of the blades. The additional cost of hedge trimmers is related to 1) The cutter gear case, and 2) The hardened steel of the blades. The cutter gear case is like an additional machine, it is the part that makes the blades move back and forth. It is made up of a cam gear, connecting rods and bearings. Most have a grease fitting which enables greasing on a regular basis. When the blades are “forced” from cutting things that are too hard and/or too big – 1) the gear case internal parts will jam and break, and the cutter blades will not work; and/or 2) the blades will become damaged and will need to be replaced. (Do not use the hedge trimmer if the blades are broken.) In order to replace the blades, the gear case will need to be opened up, and parts replaced. HAND-HELD, EXTENDED REACH. SINGLE/DOUBLE SIDED. Hedge trimmer generally need to cut horizontally (the top of the hedge) and vertically (the sides of the hedge). Know the height and width of the hedge that you will be cutting. For hedges that can be reached while standing on the ground, the hand held (24”, 30”, 40”) is usually the trimmer of choice. Single sided trimmers are usually 30” or 40”. With these trimmers you can only cut in one direction. The double-sided trimmer allows you to cut in both directions, but usually comes in shorter lengths. In either case, operators should wear protective leg gear to prevent injuries. There are some safety videos for non-believers about the dangers when using hedge trimmers. For taller hedges, rather than using a ladder, consider either a short shaft (half the length of a line trimmer shaft) or an extended reach hedge trimmer (the same length shaft as a hedge trimmer). The extended reach comes with an articulating cutter head allowing the operator to cut the horizontal portion of a tall hedge while standing on the ground. No matter which style of hedge trim- mer you have, BLADES NEED TO BE SHARPENED to get a clean, crisp cut. The Do you know enough to buy a HEDGE TRIMMER? Beforepurchasinga trimmertakeinto accountsizeandrate ofgrowthofhedge bolts and nuts holding the blades together need to be checked and adjusted. If the bolts are too loose, the blades will not meet properly; if they are too tight, the blades will not move. I recently spoke with a grounds supervi- sor who had several hedge trimmers which were not working. I asked him if he thought that this was a coincidence. I suggested that he examine what they were trying to cut, or the way that the operators were using the machine, before he bought a new machine. It was like a light went on—he hadn’t thought about that. Get the right tool for the job.

To help create a meditative space, particu- larly in healing gardens, provide a natural distraction, also known as a ‘fascination’. There are so many to choose from, from sculptures to aspects of nature aptly described by Kaplan, Kaplan and Ryan, in With People In Mind. “Nature is well en- dowed with objects of fascination in flora, fauna, water and the endless play of light.” In my experience, these ingredients will create wonderful places to sit. I spoke one day to a cancer survivor, who was sitting on a carved bench custom made to fit most garden visitors perfectly – a Good Bench that has a quiet back formed by a curving wall, and offers a view of low plantings and spruces, with a lovely church window and tower beyond. “I have been treated twice for cancer at Uni- versity Hospitals in the past seven years and today I am a happily, healthy person who rarely thinks of myself as a cancer survivor,” she said. “As I … sat quietly by myself on one of the rocks that creates a private space at the back of the garden, a wave of emotion washed over me that was completely unexpected.” These unexpected moments are so often due to the salutogenic design of a good bench – design that encourages use, vitality, health and wellness.

This is the last of four articles about spraying crops and weeds. It is based on the Purdue Extension publication, “Adju- vants and the Power of the Spray Droplet (PPP-107).” P esticide products on the market contain more than just active ingredients. They con- tain other ingredients added by manufacturers to stabilize the product and protect its performance. Glycol may be included in water-based formulations, for example, to stabilize them during a freeze-thaw cycle. Glycol won’t keep the pesticide from freezing, but will protect it from degrading when the product thaws. There may be addi- tives to thicken a formulation or stabilize chemicals. Surfactants or other adjuvants may also be included in pesticides to improve their function. The addition of adjuvants to pesticide products by the manufacturer, however, has disadvantages. An adjuvant that is compatible with the active ingredient under dilute conditions may be incom- patible in the concentrated product. Similarly, an organosilicone surfactant may be stable in a spray tank, but unstable on a shelf after several years. The active ingredient, or ingredients, is the most valuable component of the pes- ticide product. Therefore, manufacturers strive to present the most effective prod- uct in a stable, easy to use formulation. Adding adjuvants, however, increases the cost of the product and may make it less competitive on the market. Manufacturers have several reasons to leave the addition of adjuvants to the applicator. Therefore, applicators must consider a number of factors when pre- paring a spray mixture. ■■ Local water quality features, such as pH and hardness. ■■ Final volume of the spray. The amount of adjuvant is usually calculated on a volume-to-volume rate and the manufacturer cannot know the requirements of the individual applicator. ■■ Local differences in the target pest. A pest may be more difficult to control in some areas and require more or less of an adjuvant. Timing and crop tolerance also need to be considered. ■■ Local or regional weather conditions that may influ ence the amount of adjuvant need ed. In hot, dry weather for example, humectants (evaporation retardants) and drift retardants may be needed. They usually are unnecessary in wetter, more humid climates, how ever, and adding them would be an unnecessary expense for the manu facturer.

  • 15. HAWAIISCAPE.COM 29THE VOICE OF HAWAII’S GREEN INDUSTRY WWW.AMERICANMACHINERYHAWAII.COM The pesticide label gives the applica- tor information developed over years of testing by the manufacturer. This infor- mation may include: a specific recom- mendation to use an adjuvant, whether adjuvants are prohibited, or provide no information about an adjuvant. Adjuvants “Unless specific tank mix directions are given in Corn Use Directions, always use a methylated seed oil (MSO) or a pe- troleum-based vegetable seedbased oil concentrate (COC) with [product name].” —from the “Additives” section of an herbicide label Labels Prohibiting Specific Adjuvants Sometimes pesticide labels will state that the use of an adjuvant is unnecessary, will make the pesticide less effective, or may injure the crop. If spray drift control is a component of a new pesticide, man- ufacturers may warn that adding other adjuvants may increase drift. Though the applicator takes full responsibility for possible unintended consequences, the use of adjuvants can produce excellent results. The decision is assisted by knowing the following: ■■ Set-up of the sprayer ■■ Properties of the water in the tank mix ■■ Main pests being targeted ■■ Rate of pesticide and volume of water used ■■ Environmental conditions. ■■ Previous experience with the pesticide and adjuvant. Spray Drift “The best drift management strategy and most effective way to reduce drift potential is to apply large droplets that provide sufficient coverage and control. Applying larger droplets reduces drift potential but will not prevent drift if ap- plications are made improperly or under unfavorable environmental conditions.” —from the “Managing Off-Target Mo Pesticide labels may describe condi- tions that suggest a type of adjuvant may Labels on some adjuvant products may warn users as follows: ■■ “High relative humidity may in crease the risk of temporary discol oration. Use of surfactants is not recommended.” ■■ “Use only nonionic surfactant on ornamentals. Do not use a crop oil concentrate with [product name] on ornamentals.” ■■ “Do not add surfactants, additives containing surfactants, buffering agents, or pH-adjusting agents to the spray solution when [product name] is the only pesticide used.” ■■ “Certain spray tank additives (adju vants, wetting agents, surfactants), liquid fertilizers, and tank mixtures containing emulsifiable concen trates may reduce the selectivity on turfgrass. Use adjuvants and spray additives or tankmix combinations only when your experience indicates that the tank mixture will not result in objectionable turf injury.” If adjuvants are already included in a pesticide product, adding more may be unnecessary, reduce effective- ness, or cause crop damage. For example, adding a surfactant to a fast-acting herbicide can increase the risk of injury to the crop. The label of one herbicide has the follow- ing warning: “Temporary discoloration of some turf types may result from use of surfactants or adjuvants with [product name]. High temperatures and high relative humidity may increase the risk of temporary discoloration. Use of surfactants is not recommended.” be effective. For example, it may state that when applying the pesticide in low relative humidity the equipment should be adjusted to produce larger spray drop- lets. You may be able to accomplish this, however, by using a humectant to keep smaller droplets from evaporating. Or you might use a deposition or retention (drift suppressing) agent that would increase the overall size of the droplets. Representatives from pesticide manu- facturers, consultants, local crop advisors, or university extension agents may offer important advice. They not only have the When Labels Say Nothing About Adjuvants The manufacturer may not recommend or prohibit the use of adjuvants to its product. If the label does not prohibit the addition of an adjuvant, it is not against state or federal law to do so. Pesticide products are often formulated for various types of applications and some situations may require adjuvants when others do not. Tank Mixes “If this product is used in combina- tion with any other product except as specifically recommended in writing by [the man- ufacturer] then [the manufacturer] shall have no liability for any loss, damage, or injury arising out of its use in any such combination not so specifically recom- mended.” —from the “Uses With Other Products” section of an herbicide label There is a wide range of adjuvants on the market and they are constantly changing. Pesticide manufacturers cannot test them all. Changing the pesticide label is also time-consuming and must be approved by the U.S. Environmental Protection Agency. Therefore, manufacturers may only make general recommendations on their labels, to give more flexibility of use to the consumer and not to discour- age the makers of adjuvants from devel- oping new products. If an adjuvant is not recommended on the pesticide label, however, the responsi- bility for its use is the applicator’s alone. The manufacturer of the adjuvant may specify on their label that the surfactant “is recommended for use with those pesti- cides whose label recommends a non- ionic wetter/spreader-type adjuvant,” or “Always refer to the label on the product before using [name of adjuvant product] or any other product.” experience, they may know if research has been done with the pesticide product or adjuvant for a specific pest and on a particular crop.

  • 16. 30 LANDSCAPE HAWAII JULY | AUGUST 2015 Plumeria RUST BY CAROL KWAN PHOTOS BY SCOT NELSON P lumeria is a popular or- namental plant in Hawaii and also serves as a sig- nificant floricultural crop with average annual sales of flowers in the State of over $500K per year, primarily for the lei industry. In 1991, Plumeria rust leaf disease became established on Oahu and quickly spread throughout the State. It is easily recognized by its yellow spots on the leaves with yellow-orange powdery spore masses on the underside of leaves. Most Plumeria cultivars grown in Hawaii are susceptible. Plumeria rust is caused by the fungus Coleosporium plumeriae. The pathogen infects only the leaves, not the stems or flowers. When leaves are severely dis- eased, they may dry, curl, become distort- ed, and drop from the tree. Total defolia- tion of the tree may occur. The disease is more of a problem in warm, moist areas. While treatment with listed fungicides such as Eagle (40 WP or 20EW) with an active ingredient of mycobutanil or Heritage with an active ingredient of azoxystrobin is possible, planting resis- tant species or hybrids is a better option. Plumeria stenopetala and Plumeria caracasana have been found to be highly resistant to this disease. Growing Plume- rias in drier areas with wider spacings to enhance airflow also helps to reduce infestations of Plumeria rust, as does avoiding monocultures. Picking up and destroying fallen leaves may also help since these are a source of spores. Some biological control agents of Plumeria rust have been reported, including fungal hy- perparasites and a midge insect predator. Spraying fungicides or insecticides may disrupt the life cycles of these biological control agents.
