1. Notes from the Vegetable
Garden
When deciding what you
want to plant in your
vegetable garden, you have a
choice between planting
heirloom or hybrid plants.
Both types of plants have
their advantages and
disadvantages.
Heirloom vegetables are
open pollinated, which
means they are capable of
producing seeds that will
produce plants with the same
characteristics of the parent
plant. Hybrids, on the other
hand, are a cross breed of
two parent plants in order to
create a plant with the best
features of both parents.
Although you may grow
plants from hybrid seed
saved from the previous year,
the new generation of plants
will not have the same
characteristics of the parent
plant, as they do with
heirloom plants. Also, just
because a plant is a hybrid
does not mean that it was
developed through genetic
modification.
Heirloom vegetables date
from before 1951, when
hybrid plants came into
widespread production in the
United States. Because these
plant seeds were handed
down from generation to
generation, they acquired the
name “heirloom” or
“heritage” vegetables. Since
heirlooms are grown and
handed down for a long time,

Heirloom vs. Hybrid Vegetables—Which is Right for You?
By Jeff Addis, Penn State Master Gardener
Autumn is here—which
means that dreaded frost
isn’t far behind, forcing even
the most stalwart of
gardeners to beat a hasty
retreat to the warmth of their
favorite sweaters. Sadly, the
first hard frost, typically
arriving in mid-October in our
area, generally sounds the
death knell for the vegetable
gardening season.
Or does it? If you can’t
bear to lose that lettuce or
part with those peppers just
yet, there is hope for
extending the season: row
covers. Row covers are
essentially blankets for your
vegetables: plastic or gauze-
like fabric sheets that can
ward off frost damage and
extend the growing season
well into the fall.
Row covers can be made
from a number of materials,
including spun-bonded

2. For prime health and
productivity, prune your
raspberry canes during their
dormant period. Guidelines
often suggest pruning in
February or early March;
however, I was glad I pruned
on a nice January day this
year. The mild winter and
early spring brought buds and
growth much earlier than
usual. Ideally, pruning should
happen before leaf buds start
to pop out.
Understanding their
growth pattern is key to
pruning raspberries. The
roots and crowns are
perennial, while the canes are
biennial—growing one year
and producing fruit the next.
The first year a cane emerges,
it is called a primocane. In its
second year, it is called a
floricane (or fruiting cane).
Secondly, you must know
your variety. Do you have
summer-bearing or
everbearing raspberries? The
former bear one crop in the
summer, while the latter bear
a small summer crop and a
heavier fall crop. These
different fruiting patterns call
for different pruning
methods.
If you have everbearing
raspberries, dislike fussy
pruning, and don’t mind
sacrificing your summer crop,
you can prune all the canes
down to two inches each
dormant season. This will
result in one heavier and
earlier crop on primocanes in
the fall. If you want to retain
both summer and fall crops
of everbearing varieties,
however, more selective
pruning will be necessary, as
with summer-bearing
varieties.
Dormant-season selective
pruning has three steps:
remove the spent floricanes,
thin out weak primocanes,
and prune back vigorous
primocanes. The spent
floricanes are quite easy to
spot: their bark will be gray,
peeling, and the canes will
look dried up. In summer-
bearing varieties, these spent
floricanes will also have more
laterals, giving them a more
branched appearance.
(Dormant everbearing
primocanes will have laterals
just near the tip.)
Take the spent floricanes
out at ground level. Also
prune out any primocanes
with a diameter thinner than
a pencil. These lack sufficient
vigor to produce well.
Vigorous primocanes can
be topped to about chest
height. Everbearing

raspberries sometimes grow
so vigorously that they need
to be tipped in the spring at
about 3 to 4 feet above
ground level. Tip just above a
bud. Avoid tipping just below
a bud, as this leaves sections
of cane prone to disease
problems.
Do not compost the
canes, as they may carry
disease and do not break
down readily. Bundle and
store pruned canes away
from the patch. After giving
hibernating pollinators a
chance to emerge from
hollow spent floricanes once
temperatures top 50 degrees
F, send the canes out with
the trash.

3. Choosing Plants
One of the easiest ways to
reduce chemical use in the
garden is to select pest and
disease-resistant plant varieties.
Many vegetable cultivars are
more resistant to powdery
mildew, bacterial wilt, blight,
beetles, and other pests.
Do some research before
shopping, and check
plant labels.

they have become adapted to
an area’s soil, climate, and
pests, which may be an
advantage over hybrid plants.
Heirlooms, as opposed to
hybrids, are not used in large
scale agriculture. Since
hybrids were developed for
their ease of shipping,
uniform appearance, large
productivity, and ability to
grow well all over the
country, they are the
loosely drape the cover over
the plants. This affords
decent frost protection, but
resting row covers directly on
top of vegetables can also
damage the growing shoots
of some plants by snapping
them off or by bringing them
in close contact with frost.
Slightly more involved,
but offering greater
protection, are row covers
supported by a framework.
This setup, which can be as
simple as a basic A-frame
“tent” created by draping the
cover over stakes in the
middle of the row, creates a
low tunnel framework above
the plants. This extra
clearance protects your
vegetable plants’ tender
shoots and allows more heat
buildup.
Regardless of which
method you choose, you
must anchor the sides of the
row cover to prevent it from
blowing away. This can be
easily accomplished by piling
bricks or stone or soil along
the edges of the cover.
Depending on the quality
of your row covers, you may
be able to get several
seasons’ use out of them. An
added bonus of row covers:
besides keeping plants alive
in the fall, they can also be
used to get a head start on
the growing season in early
spring!
polyester, polypropylene, or
polyethylene, which all have
varying degrees of heat
retention and permeability to
sunlight, water, and air. The
level of frost protection
(anywhere from two to seven
degrees Fahrenheit) depends
primarily upon the heaviness
of the material—heavier
covers equal better
protection. Row covers are
available from seed catalogs
and from garden supply
stores, or they can also be
purchased online.
You have two general
options when installing a row
cover: floating row covers, or
row covers set atop a
framework. Floating row
covers are much simpler to
create, requiring you only to

vegetables you usually find in
grocery stores throughout
the year. Heirlooms usually
do not produce as heavily as
hybrids, but they have been
shown to often taste better,
which may be the most
important factor to a home
gardener. Some popular
heirloom varieties include:
‘Chioggia’ beets; ‘Savoy’
cabbage; ‘Buttercrunch’
lettuce; and ‘Brandywine’ or
‘Black Krim’ tomatoes.
Hybrid vegetable plants
have a smaller gene pool than
heirlooms, which can lead to
increased pest and disease
problems. However, hybrid
plants produce a greater
amount of vegetables than
heirlooms, so depending on
what the home gardener is
looking for, either a hybrid or
an heirloom plant will fit their
needs perfectly.

4. Pesticides are poisonous. Read and follow label directions and safety precautions on labels. Handle carefully and
store in original labeled containers out of the reach of children, pets, and livestock. Dispose of empty containers
right away in a safe manner and place. Do not contaminate forage, streams, or ponds.

Storage conditions are
characterized by temperature
and humidity.
Cold, moist storage is
defined as 32-40° F and 90-
95% relative humidity. These
are ideal conditions for root
crops, such as beets, carrots,
horseradish, and potatoes;
and cole crops such as
cabbage. Temperatures
should not drop below 32°F.
Cool, moist storage is
defined as 45-50° F and 80-

You’ve spent all summer
nurturing your wonderful
home-grown produce. You’ve
enjoyed it fresh, but you’d like
to store the bounty for use
during cold winter weather.
Different types of produce
require different storage
conditions. Although you may
not be able to provide perfect
conditions, an unheated but
well-ventilated basement is
often a good storage location
for many vegetables.
Lacking a basement, a
second refrigerator, or a root
cellar, there are some very
creative and ingenious
methods to store produce
outdoors, using the natural
warmth of soil to keep
produce from freezing while
still remaining fresh. These
tomatoes can be ripened in
these conditions and, by
wrapping each tomato in
newspaper, kept for 3 to 5
weeks.
Cool, dry storage is
defined as 45-50° F and 50-
60% relative humidity. This is
the best situation to keep
onions for winter storage.
Warm, dry storage is
defined as 55-60° F and 60-
70% relative humidity, ideal
for winter squash and
pumpkins. These fruits should
be harvested before frost,
with 3-4” stems left on.
Warm, moist storage is
defined as 55-60° F and 80-
85% relative humidity; sweet
potatoes are best stored in
these conditions.

use for storage, the
condition of the produce
going into storage is critical
to maintain its quality for
the longest time. Select
only mature and
undamaged produce for
long-term storage, and be
sure to clean it off carefully,
either by washing or with a
soft brush. Any bruises,
cuts, or wounds to the skin
will lead to more rapid
decay or disease problems.
Some vegetables, such as
onions, winter squash, and
potatoes, need a curing
period to dry and toughen
the skin before being put
into storage.
