Gardening in S. CA IS different

What makes us so unique?
Latitude & coastal position – mediterranean climate Mild rainy winter/spring
Moderately hot, dry summer/fall
Year-to-year variability
Extreme elevation changes Foothills and mountains have
very different climate than our local ‘lowlands’
Soils – our lowland soils are mostly sedimentary (ocean/river deposited)

You likely live in Sunset Zone
22, 23 or 24
Sunset Zone 24
Coastal Marine Zone
Where hills/cliffs/palisades are low/nonexistent, it runs inland several miles.
Soils tend to be sandy to sandy-clay
Climate zone is almost completely dominated by the ocean – a mild, marine climate. Winters are mild, summers cool, and the
air seldom really dry.
On many days in spring and early summer, the sun doesn’t break through the high overcast until afternoon.
Record heat usually comes in early October, carried to the coast by Santa Ana winds. The wind’s power and dryness usually causes more problems than the heat itself.
Some plants bloom all year long

los-angeles-area-00418000067298/
This is a wonderful
Zone for gardening!
Sunset Zone 23
Coast Thermal Belt Mostly influence by oceans but
sometimes influenced by inland heat
Frosts don’t amount to much – 85% percent of the time, Pacific Ocean weather dominates; interior air rules only 15% percent of the time. A notorious portion of this 15 percent consists of those days when hot, dry Santa Ana winds blow.
Lacks either the summer heat or the winter cold necessary to grow pears, most apples, and most peaches. But it enjoys considerably more heat than Zone 24
Temperatures are mild, but severe winters descend at times.

Sunset Zone 22
Cold-winter Coastal
Cold-winter portions of S. CA coastal climate
Is a coastal climate - influenced by the ocean approximately 85% of the time).
Average summer temperatures warmer than Zone 24
When temperatures drop in winter, these cold-air basins have lower winter temperatures than those in neighboring Zone 23.
No pronounced chilling period – limits growth of plants from local mountains that need a cold dormant period

One key to wise gardening: becoming
more aware of your climate
Read the weather forecasts like a hawk – they are a good clue to things you’ll need to do or not do
Set out a rain gauge and chart precipitation
Indoor-outdoor thermometer/ humidity meter
Chart soil moisture from Apr-Oct.
Become more aware of wind: daily patterns; direction; monthly patterns; ‘unusual’ events

Several good general books specific to
our area (L.A. county)

We’ll begin our tour of the gardening year in July
Why? - it’s a time of endings & beginnings
The spring bloom season is at it’s end
The warm weather really starts in – true beginning of the dry season
It’s a good time to evaluate what worked – or didn’t – and plan for the next season
Summer vegetables and fruits start to ripen

October: lots of preparation
Planning/Preparation: Purchase plants from native plant
nurseries/sales; place in semi-shade and water regularly until planted out.
Consider adding some decorative and educational signs to your garden; explore your options – purchase/ create, then install after pruning
Hardscape/General: Finish installing any hardscape: fences,
paths, patios
Re-apply mulch after pruning

http://www.calvin.edu/news/archive/a-perennial-the-native-plant-
sale
October: time for some planting
Propagation: From seed: cool-season grass plugs;
annual wildflowers, bulb seeds in nursery containers; winter veggie crops. Keep them well-watered.
Start chilling seeds w/ shorter (1-2 month) pre-plant stratification period; check for roots every 2 weeks – plant in nursery containers when first roots emerge
Take semi-soft wood cuttings of ceanothus, manzanita for propagation
Planting: Plant out cool-season vegetables from
starts/pony-packs or from seed

http://nadiaknows.com/tag/southern-california-planting-guide/
Watering: prepare for the rainy season – but water like
summer if needed
Watch weather forecast like a hawk!!!
Taper off watering all but Zone 2-3 & 3 plants. Keep Zone 3 plants watered – particularly if Santa Anna winds are predicted
Once rains saturate the soil you can turn off your irrigation system (if you have one); check soils periodically during hot, windy, dry weather and water as needed
Install/repair/clean rainwater collection/infiltration system (if not done in Sept.)
© Project SOUND
http://en.wikipedia.org/wiki/Rain_gauge
Set out/clean rain gauge
October: time for fall pruning??
Pruning: major pruning month, particularly for Water Zone 1 and Zone 1-2 plants
Prune to shape/thin: Ribes spp. - Be sure to prune Ribes
now, as they can bloom very early
Most summer-dry shrubs & sub-shrubs/perennials (particularly Coastal Sage Scrub and Coastal Shrubland species)
Hedge-shear – now through Dec. best time for mature plants
Divide native bulbs/corms; store or replant (better)
Remove old leaves, dead stems, tidy up perennials, groundcovers and ornamental grasses
© Project SOUND
The trick is to prune before
the rainy season but not
during hot, dry periods – to
minimize stress on the
plant
1/6/2013
14
The pleasures of fall
begin
Edibles/crafts: Dry aromatic prunings for
seasoning/tea/potpourri
Save artistic-looking materials for fall/winter decorations, flower arrangements, etc.
Dye some yarn with prunings; or dry the dye-stuff for later
Carve a pumpkin – or make a pie
Enjoying the garden: Go to the native plant sales; see what’s
new, ask questions
Visit a new-to-you native plant garden; take your camera and notebook to jot down ideas.
Enjoy the play of tans, browns and grays – a subtle sophisticated color palette
Mother Nature’s advice: don’t fight the weather – work with it.
