The first two years can be a little scary…..




                                     © Project SOUND
…trust me, it’s even more scary for the plants!

                        Nursery life is heavenly:
                           Plenty of water
                           Nice, appropriate, well-
                            drained potting soil
                           Extra nutrients
                           A little extra shade/
                            temperature control
                           Pest-free
                           Basically, a coddled life-
                            style that allows many of
                            them to survive infancy
                            (as they rarely would in
                            the wild)

What happens in nature? [Ceanothus]
 Out in nature               In the new garden
 A big disturbance –        A big disturbance – you remove
  fire/etc. removes at        existing plants
  least the shoots of
  existing plants            Plant Year 1 – the plant is established
                              in the nursery – likely more water,
 Plant Year 1 – with         nutrients than in nature
  adequate rainfall seeds
  to sprout & establish new  Plant Year 2/Garden Year 1 – you plant
  seedlings; root system      your new Ceanothus in the garden –
  develops                    what a shock! Some root/shoot
                              growth
 Plant Year 2 – chugging
  right along expanding      Plant Year 3/Garden Year 2 –
  roots & shoots              developing good roots & shoots

 Plant Year 3 – pretty      Plant Year 4/Garden Year 3 – almost
  much established            established            © Project SOUND
10 Lessons to help you – and your plants -
       through the first two years




                                  © Project SOUND
What is the ‘Establishment Phase’?
         The period in which a new plant
          becomes relatively self-sustaining
          (when given it’s requirements) – a
          gradual process
         Involves two aspects:
            Acclimating to the garden environment
            Developing sufficient root structure to
             support and sustain the plant

         Generally, the plant becomes 2-3
          times its planting size during this
          Phase
         Plants require extra care during the
          establishment phase

What is the ‘Establishment Phase’?
                Length varies by species,
                 but some general rules of
                 thumb:
                   Annuals: 1-2 months
                   Herbaceous perennials: 1-3
                    years
                   Perennial grasses: 1-2 years
                   Local sub-shrubs: 1-2 years
                   Woody shrubs & trees: 2-5
                    years; the larger & slower-
                    growing species take up to 5
                    years

What is required during the Establishment
                 Phase?

                      Increased observation
                       – as with any baby
                      Extra water during dry
                       periods – including
                       prolonged winter dry
                       spells and summer/fall
                      Decreased competition
                       from other plants –
                       most notably weeds

Lesson 1: Plant with the seasons




                             © Project SOUND
What do we mean by ‘plant with the seasons’?




                                   © Project SOUND
The growth cycle of S. CA native
perennial species (herbaceous to woody)

                Fall/winter rains (Dec-Mar)
                     Seeds germinate (many)
                     Begin above-ground stem growth
                     Leaf out (may be ‘spring’ leaves)
                     ‘early’ flowering – some species


                Spring warm/dry down period
                 (Apr-June)
                   Seed germination (warm weather)
                   Continue stem growth
                   Many will flower

Advantages to planting during the rainy
                                      season
 Saves water – soils are naturally
  moist (Water Zone 3) during the
  critical first few months
 Vulnerable plants get the best
  water possible; dissolved oxygen
  & nutrients
 Vulnerable plants are not
  exposed to temperature
  extremes (at least in the past)
 Soils are well-saturated –
  promotes deep/wide root
  growth
 Coincides with native plant’s
  normal growth cycle; plants are
  primed to grow at this time

The benefits – and challenges – of where we live
 We can grow plants from a number of plant
  communities:
      Wetland/riparian
      Northern coastal prairie/CSS
      Southern coastal prairie
      CSS
      Chaparral
      Southern oak woodland
      Mojave & Sonoran deserts

 We need to be aware of local weather patterns
    Winters may be overly dry – or wet
    Plants from some communities need more water than we usually
     get – at least in the summer
                                                     © Project SOUND
Newly planted native plants should get a
           thorough soaking

                  Soak new plants no matter
                   what the planting season
                  The first watering is
                   important – over-soak to
                   settle the soil & remove air
                   pockets
                  Overhead watering is fine –
                   the plants will think it’s
                   raining

Gardens in Mediterranean climates
 (including S. CA) have three Water Zones

 Zone 1 – no supplemental summer water; soils
  are dry in summer/fall.
 Zone 2 – occasional summer water; soil is
  allowed to dry out between waterings.
  Watering is slow & deep to replenish the soil
  water stores. In most gardens, you will water
  deeply 1-2 times per month in summer.
 Zone 3 – regular water; soil is usually moist to
  soggy, even in summer.

Why more water during the first year?

                    Weaning from ‘nursery
                     conditions’ which
                     included plenty of water
                    Less cover/shade =
                     higher evaporation rates
                    Less developed/
                     efficient root systems -
                     < 10% of area covered by
                     roots

                                                first year; water
                                                as needed using
                                                the ‘rules of

                                               Remember: some
                                                areas may dry out

Some more irrigation tips for watering young
native plants     For individual plants, drip irrigation or
                          hose watering is best. You can even use
                          a ‘Homer Bucket’ for individual plants.
                        For large areas, micro-sprinklers or
                         soaker hoses are best – good flexibility,
                         control & coverage.
                        Don’t forget to move the irrigation out
                         as roots grow; make sure that the
                         entire root system gets wet.
                        Because conditions vary from garden to
                         garden, and even within gardens, the
                         best irrigation schedule is determined
                         by watching your plants. Manually set
                         each zone on the controller.
                        Relax: in well-drained soils, water is not
                         typically an issue when the appropriate
                         plants are chosen for the site (i.e., full
                         sun, coastal...), and planting takes place
                         during the cool, rainy season

Why do bunchgrasses mature quickly
              (have a short establishment Phase)?

                                                       Perennial grasses tend to grow
                                                        quickly – they establish an
                                                        extensive root system the
                                                        first year
                                                       They tend to have relatively
                                                        deep roots (3+ feet) compared
                                                        to non-native lawn grasses
                                                       S. CA bunchgrasses tolerate
                                                        dry conditions really well

                                 Foliage: effect depends on species
                                    Evergreen plants usually produce no
                                     new leaves – but retain leaves
                                    Many plants in some plant communities
                                     (Coastal Sage Scrub; Coastal Prairie;
                                     Coastal shrubland) are drought

                                    Some plants from these communities
                                     produce special ‘summer leaves’ that
                                     may remain on the plant until late
                                     summer
Why this variability & what      May leaf out & even flower if summer

   Black Sage is one tough plant – and part of the reason is
    it’s summer dormancy!!!!
Watering rules of thumb: Black Sage – Salvia mellifera –
Zone 1-2
                               Year 1:
                                   First winter/spring – Zone 3 (rain
                                    alone may suffice)
                                   First summer/fall – one full Water
                                    Zone more than it’s mature Zone –
                                    decrease slightly in Aug/Sept.
                               Year 2:
                                   Second winter/spring – water only
                                    if rains are inadequate
                                   Second summer/fall:
                                        Grasses & local native sub-shrubs:

  their water)                       their water)
 Causes emboli (air bubbles) in    Less apt to develop emboli

 Causes plants to lose their       Thus, they can remain
  leaves & become dormant            evergreen
 CSS shrubs are programmed         Adult plants (which are
  to grow rapidly in response        drought tolerant) don’t need

Take-home message

       Perennials from CSS, Coastal
        Shrubland and Coastal Prairie have
        dense, shallow roots

       They tend to become established
        quickly (1-2 years) and be < 6 ft tall

       They tend to dry out in early
        summer – either losing their leaves
        or growing small summer leaves

       Mature plants do best with little
        (Zone 1-2) water; will stay green
        longer – but shorter-lived – with
        more (Zone 2)

Take-home message
 Plants from Chaparral have both
  shallow & deep roots, allowing
  them to maximize available
  water

 The roots take longer to develop
  – hence the longer
  Establishment Phase for
  Chaparral shrubs

 Once established, Chaparral
  shrubs are very drought
  tolerant

 The roots of Chaparral shrubs
  allow them to be both evergreen
  and a large size (usually > 6 ft)

                  Benefits of mulch
                   renewal in fall
                     Easy time – when plants
                      are dormant/pruned
                     Adds color/interest
                     Prepares garden to

                                               Occurs: coast to mountains; open
                                                areas, chaparral, woodland, forest
                                                - often riparian areas
                                               Size: 1-3+ ft; spreading – texture
                                                somewhat coarse (typical ryegrass)

                                               Water: best on moderately moist
                                                soils but fairly drought tolerant
                                               Good for natural-looking areas,

           Plants dying
           Areas with too much or too
            little water
           Erosion/drainage problems
           Gaps in the plant cover (only
            after first 2 years or so –
            hard to tell before that)
           Plants that don’t fit the
            design/ are out of place

Observations
 Species distribution has
  changed – much like in
  nature (annuals & re-
  seeders common early on)
 As expected, smaller
  plants established more
  quickly
 The early garden looks
  ‘flat’ and ‘boring’ – many
  slow-growing species not
  yet visible

                  © Project SOUND
Observations
 Some plants have not
  made it – others have
  flourished
 Some plants are now in
  too much shade –
  succession
 Some plants probably
  planted in the wrong
  place – grew too big
 Some new plants are
  needed every year to fill
  gaps

First two years 2011

  • 1. Out of the Wilds and Into Your Garden Gardening with Western L.A. County Native Plants Project SOUND – 2011 (our 7th year) © Project SOUND
  • 2. The First Two Years in the Native Plant Garden C.M. Vadheim and T. Drake CSUDH & Madrona Marsh Preserve Madrona Marsh Preserve August 20 & 23, 2011 © Project SOUND
  • 3. The first two years can be a little scary….. © Project SOUND
  • 4. …trust me, it’s even more scary for the plants!  Nursery life is heavenly:  Plenty of water  Nice, appropriate, well- drained potting soil  Extra nutrients  A little extra shade/ temperature control  Pest-free  Basically, a coddled life- style that allows many of them to survive infancy (as they rarely would in the wild) © Project SOUND
  • 5. What happens in nature? [Ceanothus] Out in nature In the new garden  A big disturbance –  A big disturbance – you remove fire/etc. removes at existing plants least the shoots of existing plants  Plant Year 1 – the plant is established in the nursery – likely more water,  Plant Year 1 – with nutrients than in nature adequate rainfall seeds to sprout & establish new  Plant Year 2/Garden Year 1 – you plant seedlings; root system your new Ceanothus in the garden – develops what a shock! Some root/shoot growth  Plant Year 2 – chugging right along expanding  Plant Year 3/Garden Year 2 – roots & shoots developing good roots & shoots  Plant Year 3 – pretty  Plant Year 4/Garden Year 3 – almost much established established © Project SOUND
  • 6. 10 Lessons to help you – and your plants - through the first two years © Project SOUND
  • 7. What is the ‘Establishment Phase’?  The period in which a new plant becomes relatively self-sustaining (when given it’s requirements) – a gradual process  Involves two aspects:  Acclimating to the garden environment  Developing sufficient root structure to support and sustain the plant  Generally, the plant becomes 2-3 times its planting size during this Phase  Plants require extra care during the establishment phase © Project SOUND
  • 8. What is the ‘Establishment Phase’?  Length varies by species, but some general rules of thumb:  Annuals: 1-2 months  Herbaceous perennials: 1-3 years  Perennial grasses: 1-2 years  Local sub-shrubs: 1-2 years  Woody shrubs & trees: 2-5 years; the larger & slower- growing species take up to 5 years © Project SOUND
  • 9. What is required during the Establishment Phase?  Increased observation – as with any baby  Extra water during dry periods – including prolonged winter dry spells and summer/fall  Decreased competition from other plants – most notably weeds © Project SOUND
  • 10. Lesson 1: Plant with the seasons © Project SOUND
  • 11. What do we mean by ‘plant with the seasons’? © Project SOUND
  • 12. The growth cycle of S. CA native perennial species (herbaceous to woody)  Fall/winter rains (Dec-Mar)  Seeds germinate (many)  Begin above-ground stem growth  Leaf out (may be ‘spring’ leaves)  ‘early’ flowering – some species  Spring warm/dry down period (Apr-June)  Seed germination (warm weather)  Continue stem growth  Many will flower © Project SOUND
  • 13. Advantages to planting during the rainy season  Saves water – soils are naturally moist (Water Zone 3) during the critical first few months  Vulnerable plants get the best water possible; dissolved oxygen & nutrients  Vulnerable plants are not exposed to temperature extremes (at least in the past)  Soils are well-saturated – promotes deep/wide root growth  Coincides with native plant’s normal growth cycle; plants are primed to grow at this time © Project SOUND
  • 14. How much do I need to water during the first two years? © Project SOUND
  • 15. Lesson 2: Water to promote survival, not abundant growth © Project SOUND
  • 16. Watering: the impact of where we live  Region 3-South Coastal  Climate Zones 22, 23 & 24  CIMIS ETo Zones 1, 2, 4 and 6  Region 4-South Inland Valleys and Foothills  Climate Zones 18, 19, 20 and 21  CIMIS ETo Zone 9 http://www.water.ca.gov/wateruseefficiency/docs/wucols00.pdf © Project SOUND
  • 17. The benefits – and challenges – of where we live  We can grow plants from a number of plant communities:  Wetland/riparian  Northern coastal prairie/CSS  Southern coastal prairie  CSS  Chaparral  Southern oak woodland  Mojave & Sonoran deserts  We need to be aware of local weather patterns  Winters may be overly dry – or wet  Plants from some communities need more water than we usually get – at least in the summer © Project SOUND
  • 18. Newly planted native plants should get a thorough soaking  Soak new plants no matter what the planting season  The first watering is important – over-soak to settle the soil & remove air pockets  Overhead watering is fine – the plants will think it’s raining © Project SOUND
  • 19. Treat new plants as Water Zone 3 for the first winter/early spring (through April)  Rains may do the job  Check soil moisture, especially if we have:  Long period (3+ weeks) with no winter rains  Very hot periods (winter Santa Anas)  Strong winds (soil dries faster than you think) http://royrector.com/garden/?p=124  Check beneath the surface (under mulch) - ~ 3-4 inches  Dig down with trowel  Use a moisture meter or soil sampler © Project SOUND http://www.ecofitt.ca/Products/WaterProducts/Lawn-and-Garden/Soil-Moisture-Meter
  • 20. So, we’ve gotten to June, and it’s starting to get hot & dry…. © Project SOUND
  • 21. The first dry season is crucial - and challenging http://dharmaconsulting.com/products/accelerating-change/  ‘Don’t under-water; plants can die before they become established’  ‘Don’t over water! It leads to the death of many native plants; their roots suffocate & die of rot or disease.’ © Project SOUND
  • 22. We’ve been led to believe that all plants grow like tropical plants… http://www.kriyayoga.com/love_blog/post.php/950 © Project SOUND
  • 23. …and now the native plant ‘experts’ are trying to give us the same 1-2-3 gardening rules http://kmgardendesign.com/Portfolio-CANativeGarden.htm © Project SOUND
  • 24. Why can’t those (@@###**) experts get their watering advice straight??? http://www.glenbrookenews.com/2009/10/04/home-owners-association-workhop/ With CA native plants, one size does NOT fit all © Project SOUND
  • 25. Why can’t those (@@###**) experts get their watering advice straight???  Your soils (and other relevant conditions) may be different  They may be talking about a different climate region (often N. CA)  They may be thinking http://www.glenbrookenews.com/2009/10/04/home-owners-association-workhop/ about different species which have different You need to consider the information source - and use the water needs Water Zone principles © Project SOUND
  • 26. Gardens in Mediterranean climates (including S. CA) have three Water Zones  Zone 1 – no supplemental summer water; soils are dry in summer/fall.  Zone 2 – occasional summer water; soil is allowed to dry out between waterings. Watering is slow & deep to replenish the soil water stores. In most gardens, you will water deeply 1-2 times per month in summer.  Zone 3 – regular water; soil is usually moist to soggy, even in summer. © Project SOUND
  • 27. Water Result/consequence Description Picture Zone (for mature plants) Many Zone 1 plants (including many native to western L.A. No supplemental Zone 1 water county & deserts) become summer dormant; some shade species remain green Includes ‘CA Natives’ from Occasional water; many plant communities; soil dries out occasional summer water Zone 2 between deep helps many species to remain waterings evergreen – many also extend bloom season Only native riparian and some Regular water; Zone 3 soil moist/ soggy mountain/N. CA species – will kill many local CA natives © Project SOUND
  • 28. Water Zone Principles for the first 2 years Interpretation: give more water  ‘Water to keep the plant than the plant’s mature Water alive, not to make it grow Zone – but as close to it as fast. Try to make the reasonable. Taper the amount of water off as the root system plant drought tolerant!’ develops.  ‘Watering less often and more deeply to stimulate Interpretation: follow good roots to grow deeper Water Zone practices (e.g. water instead of on the surface deeply and less frequently) even where they will be during the first 2 years susceptible to drying out.’ © Project SOUND
  • 29. Why more water during the first year?  Weaning from ‘nursery conditions’ which included plenty of water  Less cover/shade = higher evaporation rates  Less developed/ efficient root systems - < 10% of area covered by roots © Project SOUND
  • 30. No two gardens are alike: that’s why you need to monitor your soil moisture  Check soil moisture every 1-2 weeks during the first year; water as needed using the ‘rules of thumb’  Remember: some areas may dry out more quickly The only way you can assure that you are watering correctly is to use the Water Zone method and check your soils! © Project SOUND
  • 31. Watering rules of thumb -  Year 1:  First winter/spring – Zone 3 the first 2 years (rain alone may suffice)  First summer/fall – one full Water Zone more than it’s mature Zone – decrease slightly in Aug/Sept unless it gets summer rain in nature  Year 2:  Second winter/spring – water only if rains are inadequate  Second summer/fall:  Grasses & local native sub- shrubs: mature Water Zone  All other perennial/woody species: ½ Zone above mature Zone – decrease slightly in Year 3: large woody shrubs/trees: Aug/Sept. unless it gets occasional supplemental summer water summer rain in nature © Project SOUND
  • 32. The best ways to supply water during the first two years – S. CA gardens  Low frequency (1-4 times a month), long duration (4-12 hours) irrigation is best to thoroughly soak the soil.  Hose, drip, soaker hose or low volume "micro“ sprinkler are http://lawncare.savvy-cafe.com/save-money-and-water-with-smart-lawn-and-garden-tips-2009-08-17/ often good choices  Use overhead watering very carefully – don’t let leaves remain moist in warm weather  Do not water during the heat of the day. Try very early morning or evening (good in coastal areas) © Project SOUND http://www2.ljworld.com/photos/2009/aug/16/
  • 33. Some more irrigation tips for watering young native plants  For individual plants, drip irrigation or hose watering is best. You can even use a ‘Homer Bucket’ for individual plants.  For large areas, micro-sprinklers or soaker hoses are best – good flexibility, control & coverage.  Don’t forget to move the irrigation out as roots grow; make sure that the entire root system gets wet.  Because conditions vary from garden to garden, and even within gardens, the best irrigation schedule is determined by watching your plants. Manually set each zone on the controller.  Relax: in well-drained soils, water is not typically an issue when the appropriate plants are chosen for the site (i.e., full sun, coastal...), and planting takes place during the cool, rainy season © Project SOUND
  • 34. This class is about teaching you ‘how to fish’ http://www.clipartheaven.com/show/clipart/kids_stuff/images_(a_-_f)/fishing-gif.html © Project SOUND
  • 35. Bunchgrasses –  Year 1:  First winter/spring – Zone 3 Water Zone 1-2 (rain alone may suffice)  First summer/fall – one full Water Zone more than it’s mature Zone – decrease slightly in Aug/Sept unless it gets summer rain in nature  Year 2:  Second winter/spring – water only if rains are inadequate  Second summer/fall:  Grasses & local native sub- Deergrass – Muhlenbergia rigens shrubs: mature Water Zone  All other perennial/woody species: ½ Zone above mature Year 3: large woody shrubs/trees: Zone – decrease slightly in occasional supplemental summer water Aug/Sept. unless it gets summer rain in nature © Project SOUND
  • 36. Why do bunchgrasses mature quickly (have a short establishment Phase)?  Perennial grasses tend to grow quickly – they establish an extensive root system the first year  They tend to have relatively deep roots (3+ feet) compared to non-native lawn grasses  S. CA bunchgrasses tolerate dry conditions really well http://www.pitzer.edu/offices/arboretum/tongva_gard en/plants/19-Muhlenbergia_rigens.htm © Project SOUND
  • 37. The growth cycle of S. CA native perennial species (herbaceous to woody)  Dry period (June/July-Nov)  Stem elongation (slower; may be ‘summer’ type growth pattern)  Foliage: effect depends on species  Evergreen plants usually produce no new leaves – but retain leaves  Many plants in some plant communities (Coastal Sage Scrub; Coastal Prairie; Coastal shrubland) are drought deciduous  Some plants from these communities produce special ‘summer leaves’ that may remain on the plant until late summer Why this variability & what  May leaf out & even flower if summer does it mean for watering? rains/watering occur © Project SOUND
  • 38. A comparison of two shrubs Coastal Sage Scrub Chaparral Black Sage – Salvia mellifera Bigpod Ceanothus – C. megacarpus © Project SOUND
  • 39. California Black Sage – Salvia mellifera
  • 40. Black Sage – Salvia mellifera  A “CA coastal plant”  Coastal ranges from San Jose to Baja  Channel Islands and Baja coastal http://www.swsbm.com/Maps/Salvia_mellifera.gif islands  on South and West facing slopes on rocky soil in California's coastal sage scrub and chaparral plant communities  Often in slightly wetter sites than other native Salvias  Common; may form dense thickets in wild http://ucjeps.berkeley.edu/cgi-bin/get_JM_treatment.pl?4745,4865,4880
  • 41. http://www.cnps.org/programs/vegetation/Coyote_Ridge/images/10a_Artemisia_californica-Salvia_mellifera_SS.jpg  Black Sage is one tough plant – and part of the reason is it’s summer dormancy!!!!
  • 42. Watering rules of thumb: Black Sage – Salvia mellifera – Zone 1-2  Year 1:  First winter/spring – Zone 3 (rain alone may suffice)  First summer/fall – one full Water Zone more than it’s mature Zone – decrease slightly in Aug/Sept.  Year 2:  Second winter/spring – water only if rains are inadequate  Second summer/fall:  Grasses & local native sub-shrubs: mature Water Zone  All other perennial/woody species: ½ Zone above mature Zone – decrease slightly in Aug/Sept.

  • 45. Big-pod Ceanothus  Soils: is a chaparral shrub  Texture: rocky or sandy best – needs well-drained soil  pH: any local  Light:  Full sun to light shade  Benefits from afternoon shade in hot inland gardens  Water:  Winter: needs good winter rains  Summer: low needs – Zone 1- 2 (water very infrequently, if at all, once established)  Fertilizer: none; likes poor soils; likes an organic mulch © Project SOUND http://farm4.static.flickr.com/3373/3275037528_782b3c6c8f.jpg?v=0
  • 46. Ceanothus –  Year 1: Water Zone 1-2  First winter/spring – Zone 3 (rain alone may suffice)  First summer/fall – one full Water Zone more than it’s mature Zone – decrease slightly in Aug/Sept. unless it gets summer rains in nature  Year 2:  Second winter/spring – water only if rains are inadequate  Second summer/fall:  Grasses & local native sub-shrubs: mature Water Zone http://www.calflora.net/bloomingplants/bigpodceanothus.html  All other perennial/woody species: ½ Zone above mature Zone – decrease slightly in Aug/Sept.

  • 47. Comparison of yearly cycle: CSS vs Chaparral Coastal Sage Scrub Chaparral  Environmental  Environmental  Lower total moisture/rain  Higher total moisture  Rain & snow  May also have summer rains  Moderate temperatures  Wider temperature extremes  Less natural mulch  More natural mulch  Growth patterns  Growth patterns  Summer deciduous (facultative)  Evergreen  Short, rapid growth season –  Longer growth season – winter through May/June spring through summer  May produce separate ‘summer  May have growth/flowering foliage’ (late spring) that is after summer rains more drought resistant © Project SOUND
  • 48. What happens when mature shrubs dry out? Coastal Sage Scrub Chaparral  Twigs become very  Twigs don’t become so dehydrated (lose 75-90% of dehydrated (lose 15-~40% of their water) their water)  Causes emboli (air bubbles) in  Less apt to develop emboli the water conducting vascular tissue (Xylem tubes)  Causes plants to lose their  Thus, they can remain leaves & become dormant evergreen  CSS shrubs are programmed  Adult plants (which are to grow rapidly in response drought tolerant) don’t need to water – they need to ‘re- to react so quickly to water grow’ their vascular tissue © Project SOUND
  • 49. Differences in root growth reflect native environment Coastal Sage Scrub Chaparral  Environmental  Environmental  Higher total moisture  Lower total moisture/rain  Rain & snow  May also have summer rains  Moderate temperatures  Wider temperature extremes  Less natural mulch  More natural mulch  Roots – 1-8x above-ground  Roots – 6-40x above-ground area area  Shallow roots – like CSS; grow  Wide-spread, multi-branched with rain (net-like) shallow (0-3 ft)  +/- Intermediate (often re- roots – very efficient for sprouting) roots water, nutrient up-take; grow  +/- Very deep vertical roots – with winter rains down into bedrock & watertable © Project SOUND
  • 50. Take-home message  Perennials from CSS, Coastal Shrubland and Coastal Prairie have dense, shallow roots  They tend to become established quickly (1-2 years) and be < 6 ft tall  They tend to dry out in early summer – either losing their leaves or growing small summer leaves  Mature plants do best with little (Zone 1-2) water; will stay green longer – but shorter-lived – with more (Zone 2) © Project SOUND
  • 51. Take-home message  Plants from Chaparral have both shallow & deep roots, allowing them to maximize available water  The roots take longer to develop – hence the longer Establishment Phase for Chaparral shrubs  Once established, Chaparral shrubs are very drought tolerant  The roots of Chaparral shrubs allow them to be both evergreen and a large size (usually > 6 ft) © Project SOUND
  • 52. Watering rules of thumb -  Year 1:  First winter/spring – Zone 3 the first 2 years (rain alone may suffice)  First summer/fall – one full Water Zone more than it’s mature Zone – decrease slightly in Aug/Sept unless it gets summer rain in nature  Year 2:  Second winter/spring – water only if rains are inadequate  Second summer/fall:  Grasses & local native sub- shrubs: mature Water Zone  All other perennial/woody species: ½ Zone above mature Year 3: large woody shrubs/trees: Zone – decrease slightly in occasional supplemental summer Aug/Sept. unless it gets water; all others at mature Zone summer rain in nature © Project SOUND
  • 53. What plant communities normally experience some summer moisture? Summer monsoons Summer fogs  Sonoran Desert  Northern Coastal Sage  S. CA Mountain Scrub/Coastal Chaparral Communities  Chaparral (+/-)  Fog events (usually over several days) can provide up to 2-3 inches of precipitation  Summer monsoon events  Can occur from June-Aug usually Aug-Sept  Fog drip occurs at night  Locally rare – but can contribute significant precipitation in a single event (1/2-3”) © Project SOUND
