Plant Communities of the Santa Cruz Mtns

Leave a comment

Knowing which type of plant community you live in can make the difference between success and ho-hum results in your garden. Choose the right plant for the right place. 

Plant communities have evolved over time with geologic changes in climate, topography and soils. We have several district areas here- mixed evergreen forest and redwood forest, chaparral and the sandhills.

If you live in a mixed evergreen forest you garden with trees like coast live oak, tan oak, madrone, bay and buckeye. Understory plants include ceanothus, coffeeberry, hazel and poison oak.  Your soil contains serpentine and granite. Many other unthirsty plants like salvias, lavender, santolina, society garlic, needle and giant feather grass and rockrose also do well here. Another plant to try that will also flourish in your garden is a native of New Zealand called Coprosma.  There are many colorful varieties now available like "Evening Glow".  All are valued for their colorful variegated foliage especially in the cooler months when the leaves turn orange red.  Many coprosmas grow to 4-5 ft but Evening Glow is just 14" tall. They need little water and can be happy in full sun or partial shade.

Mixed evergreen forest may also be found along canyon bottoms near streams where bigleaf maple, white alder, cottonwood, and western sycamore trees grow.  Most plant grow lush in this deep soil.  If you are looking to add something new to your garden here consider brunnera which blooms now with tiny clear blue flowers that freely self-sow without being invasive. It has large heart-shaped leaves that are showy, too,

Chaparral areas are the hottest, driest slopes of these mountains. Dense thickets of manzanita, coyote brush, chamise, coffeeberry, ceanothus, monkey flower and sage are native here. These plants are adapted to little water and often have tiny, thick, waxy,  light green or grayish leaves. Soils tend to be rocky, shallow and overlaying rock or a subsoil that is mostly clay. Plants here need to have an extensive root system that reaches widely and deeply for water. If you live here be sure you have the spring blooming western redbud and Julia Phelps or Dark Star ceanothus. The combination of magenta and electric blue flowers is unforgettable.

The sandhills near Quail Hollow and Bonny Doon around Martin Rd. are part of an ancient sandy sea floor that was uplifted, eroded and exposed. These sandy soils lack organic matter and nutrients and their white color magnifies the temperature of the summer sun. Unique, native plants include silverleaf manzanita and Ben Lomond wallflower live here.  When you plant in these soils amend with compost to provide needed nutrients. Lewisia, a pretty little plant native to northern California, thrives in sand and gravel soils with good drainage. This 8" tall hardy perennial blooms from spring to early summer with extremely showy flower clusters in colors ranging from apricot to pink, rose and bright cherry red.  Mulch these beauties with gravel or crushed stone.

Remember right plant-right place.

It’s Spring – What do I do?

Leave a comment

Yes, we need more rain but the recent sunny weather has been good for both people and plants. I remember many years ago when we had "The Miracle March" as a local meteorologist called it. It rained for 30 days straight. This was great for the watershed but drowned new emerging roots, starving them of oxygen and causing lots of fungal problems.  Let’s hope Mother Nature spreads out the remaining precipitation keeping everyone happy.

Spring begins today. This year, especially, think of gardening as therapy.  Every moment you put in your garden is paid back with fresh vegetables and fragrant flowers.  Think about it- stir up the soil, plant some seeds and you have flowers and vegetables in a few months.  The satisfaction you get from cultivating living things is priceless.

Get started on this free therapy by tending to your garden this week:

Plant low water use plants in place of those that have been struggling. Use your precious time, space and sun to grow the plants you most want to look at, pic or eat.  As a reminder, never work with soil that is very wet and keep off your lawn the, too, as this can compact the soil.

Cut back deciduous shrubs and vines except those that flower now in the spring. Don’t prune rhododendrons, camellias, or azaleas until the last flowers have started to open and green growth has started.
Prune frost  damaged shrubs if you can tell how far down the die back goes otherwise wait until growth starts in the spring.  For your shrubs, test bark for viability by scraping with a sharp knife.

If you are interested in being less of a slave to your lawn, consider reducing the size. If you’ve decided that you don’t need a traditional grass lawn anymore at all, replace it with a sustainable alternative.

Check for early aphids and blast them off with a hose or use no-tozic sprays like horticultural oil or insecticidal soap. Check for snails and slug damage and apply organic iron phosphate bait. Earwigs and sowbugs can be controlled by organic spinosad. Reduce their numbers by eliminating hiding places.  Clean out leaf litter and garden debris and use organic iron phosphate bait.  Copper pennies in your containers can also deter them.

Get weeds out of the garden early and you’ll save yourself a lot of digging later. Weeds rob your plants of precious moisture and nutrients.

Plant cool season vegetable like peas, chard, spinach, broccoli, cauliflower, cabbage, lettuce, onions and other greens.  You can also sow seeds of beets and carrots. The soil is still too cold for tomatoes and other warm season vegetables. 

Grow the sweetest strawberries this year by planting them in a bed that receives at least 6 hours of direct sun at midday.  Don’t water too much.  This can dilute their flavor.  You want the soil to be moist but not wet. Don’t apply excess nitrogen fertilizer which causes overly lush growth at the expense of berry production. Also keep beds free of weeds and space each strawberry plant about a foot apart.

Plant a spring flowering tree such as a flowering cherry, dogwood, crabapple or plum or a native western redbud to welcome the new season and make your spirits soar.

What Zone Are We?

Leave a comment

Spring is coming. Like me, you’re  probably anxious to get started in your garden. We’ve gotten some much needed rain and hopefully there is more to come. As you’re thoughts turn to gardening, though, make sure those new plant choices are the right ones for your area.

Notice how much sun or shade an area gets during the growing season- from April through September. Knowing  also which Sunset climate zone you are in is equally as important to make sure your garden thrives. Every year I get asked which zone the areas of Scotts Valley, San Lorenzo Valley, Bonny Doon are in. It’s confusing in Sunset Western Gardening Guide as our area has many microclimates and their map is not detailed enough to reflect this. They even show Felton as being on a ridge top instead of on the valley floor. Here are some tips to help you determine in what zone you garden.

Zone 7  has the coldest winters in our area.  Very high ridge tops like the Summit area and the most northern portions of Bonny Doon lie in this zone.  My records show average winter lows ranging from 15-25 degrees based on 20 years of input from gardeners in these areas.  This does not apply to other areas of zone 7, just those around here.   Record lows have occurred during freezes in 1990, 1996 and 2007 but as gardeners we rely on average highs and lows to help guide our planting times.  Spring weather comes later in this zone with the growing season mainly from April – October.

Zone 15 – this zone encompasses most of our area.  Winter lows average 20-30 degrees. The valley floor of both San Lorenzo and Scotts Valley lie in this zone and are what I call "a cold 15".  Cold air sinks and is trapped in these areas. Often there is damage to the tips of oleanders and citrus while gardenias and tropical hibiscus need extra protection.There are warmer parts of this zone, though, where the growing season starts in March and ends in November.  These areas rarely get a freeze after March 15th or before Thanksgiving.

Zone 16 – those who live up off the valley floor but below ridge tops live in this "banana belt". Pasatiempo also falls in this thermal zone.  Light frost can occur during the winter but mostly the winter lows in this zone stay above freezing. Lucky you.

Planning for Extreme Weather

Leave a comment

Drought one year,  rainy the next.  How do you plan for these weather events in your garden?

CLIMATE-PROOFING used to mean tossing a little mulch on the garden, hauling pots of tender plants indoors or under an overhang.   But global warming and cyclical climate change has caused weather to grow so volatile that these traditional practices just don’t cut it anymore. Our gardens need year-’round help to deal with the new weather realities, including increasingly rain events in the winter and dry springs and of course our usual dry summers. . If you doubt the significant effects of climate change on our gardens, think about all the plants you consider hardy that may have died off in a really cold spell or the usually drought tolerant plants that didn’t like our dry spring last year.   The list varies by microclimate, but might include escallonia, abutilon, verbenas, Melianthus major, phormium and yuccas. Have you noticed birds returning earlier in the spring and lilacs blooming two weeks ahead of when they flowered 30 years ago?

We need a fresh arsenal of garden strategies, and it will help if we better understand the changing weather where we live and garden.  Our climate is influenced by the Santa Cruz mountain range and moderated by the Pacific Ocean.  Sixty inches of rain is "normal" for us but it’s been a few years since we’ve had this much.  While there is great year-to-year variability in our weather,  we need to be prepared for the worse case scenario.  You can lose both precious plants and trees as well as all the money and work you put into the garden.

How to deal?

• Begin by choosing tough, sturdy, self-reliant plants that need less water and fertilizer. Healthy plants are naturally resistant to pests and diseases when put in the sun/shade/water situations that suit them.

• Compost-enriched soil provides the foundation for thriving plants that are more resilient to disease, drought or insect damage. Healthy soil absorbs water like a sponge and also stores carbon from the atmosphere, helping reduce greenhouse gases.

• Reduce water consumption by using drought-tolerant and native plants, and by grouping plants with like water needs. Water with drip systems or soaker hoses; use tools like watering bags to keep new trees healthy. Remember to check whether your soil is dry before irrigating, and make sure you are watering more than just the surface.

• Weed regularly so you aren’t wasting water on nuisance plants. To keep weeds down and water in, mulch garden beds at least once a year in late winter.

• Global warming is creating what climatologists call "heavier rainfall events." This means more runoff and more stormwater problems. We can help by avoiding chemical fertilizers, pesticides and herbicides, and using porous surfaces like pebbles, gravel or pavers for patios and driveways rather than solid concrete. Install rain barrels and cisterns to capture rainwater to use for irrigation. Consider taking advantage of low-lying or boggy spots in your garden to create a rain garden, planted with moisture-loving natives, to slow down the passage of rainwater through the soil.

• Nurture the birds, bees and insects in your garden that are also confused by climate change. Make your garden a healthy habitat for all living things by eschewing chemicals. Plant a diverse array of flora that blooms early and late to encourage pollinators. Add natives and plenty of berried plants to feed and attract creatures.

• And finally, a few ideas on saving energy: Solar garden lights are the smart way to go; cut energy use on other outdoor lights by putting them on a timer. If you aren’t yet lawn-free, at least get rid of your gas mower, blower and weed eater, and use rakes and hand clippers; you’ll be rewarded with blessed quiet as well as energy efficiencies. You might consider arbors and pergolas for shade in summer and rain protection in winter. And it might not be a bad idea to invest in a rain barrel.

 Sure has been cold the past few weeks.  Many of the perennials in my garden have suffered from frost and will need to be cut back later in February or March.  After strolling through Strybing Arboretum in San Francisco recently, I’m newly inspired for the coming season.


At the arboretum you can experience unique gardens created with California natives or drought tolerant plants from Australia.   Other gardens have plants from New Zealand or So. Africa.  Meandering paths bisect each garden.   It is a marvelous place to explore and discover what plants appeal to you as each is clearly labeled.  Be sure to take your camera.  It’s a great way to see what a mature specimen of a plant or tree looks like. Those descriptions on a nursery can don’t compare to seeing a plant in person.

While you’re up in Golden Gate park  don’t miss the new museum of natural history, planetarium, tropical rainforest and aquarium.  Green technology is used and explained throughout, including the green roof.  Last summer I wrote about visiting Rana Creek nursery in Carmel and talking to the grower of the native plants that cover the roof.  The  plants selected, eight drought tolerant California natives, include  prunella, armeria, stonecrop, goldfield, lupine, poppy,  plantain and beach strawberry.  I didn’t see seedlings of the spring wildflowers on the roof when I visited but the stands of prunella and beach strawberry were thriving.  Also beach asters seemed to be doing well although they weren’t listed.  Seeds may have blown in.  If you’re thinking of replacing your traditional lawn in the spring with drought tolerant ground covers, consider these plants.   They are not only survivors but will flourish under adverse conditions. 

As I write this, I’m spending the holiday in the Seattle area near Lake Washington.  Here you can really see plants that know how to survive the elements.  Actually, it’s hard to identify most of them as they are totally covered with snow.  It snows everyday.  Beautiful white powder blankets the trees and landscape. My sister’s  perennial planters will not be joining her this spring.   So pretty to look but not that great when you venture out  to get last minute presents.  Snowplows are scarce up here.

What plants bloom in the winter where we live?  A little color at this time of year is always welcome.   Native mahonia are just coming into full and glorious yellow flower.  The hummingbirds love their flowers as well as hellebores, sasanqua camellias and strawberry trees.

Oregon  grape ( mahonia ) are deer-resistant shrubs with large, prickly leaves.  Long sprays of fragrant, yellow flowers rise above the foliage in January and February.  Blue fruit follows which is also attractive.   Mahonias grow best in partial shade but will take full sun if given occasional, deep watering in the summer.

Sasanqua camellias are valuable for their massive display of large flowers in fall and winter.  If you’re driving along and see a shrub covered with dark pink, white, lilac or red flowers, most likely it will be this plant.  They are often called the roses of winter.  Many are fragrant and can be espaliered on a trellis.  Sasanqua camellias are easy to grow in partial shade and need only moderate water. 

Another wonderful plant for winter color that I saw so many of at the arboretum is winter heath.  Heaths and heathers love acidic soil so combine well in sunny areas near rhododendrons and azaleas.  Ground cover types are smothered with lilac, pink or rose flowers starting in December and last into April. 

Don’t forget Iceland poppies, violas and cyclamen for small color accents.  Happy New Year  from The Mountain Gardener and may your garden flourish this year.

Twas the Night Before Christmas

Twas the Night Before Christmas
                 A poem for Gardeners
                    by Jan Nelson "The Mountain Gardener"

Twas the night before Christmas and all through the garden,
All the creatures were stirring,  the deer got a pardon.
The hummingbird feeders were hung by the chimney with care,
In hopes that the Anna’s soon would be there.

The flowering cherries were nestled all snug in their beds,
While visions of spring glory danced in their heads.
The summer vegetables were harvested and beds put to nap,
The compost’s a brewing so next year’s a snap.

When out on the native grass lawn there arose such a clatter,
I ran into the garden to see what was the matter.
And what to my wondering eyes should appear,
But a big flock of chickadees and eight black-tailed deer.

They spoke not a word, but went straight to their work,
The chickadees devouring aphids with amazing teamwork.
And then, in a twinkling, I heard on the deck,
Prancing and pawing, the deer making a wreck.
 

 

A hydrangea here, an abutilon there, this garden’s a feast,
Fruit, vegetables and color:  it must belong to an artiste.
We love this garden, they whispered to themselves,
With any luck,  they’ll think we’re the elves !

Beautiful flowers and nectar and fragrance abounds,
We’ll include this forever on one of our rounds.
The birds can sing and fly in the skies
But we have the charm with huge brown doe-eyes.

We get a bad rap, it’s not all our fault,
Our old feeding grounds are now covered with asphalt.
Just give us a sleigh and we’ll make you proud,
We’re good for more than just eating roses they vowed.

Call us Dasher and Dancer and Comet and Vixen,
Or Comet and Cupid and Donner and Blitzen,
Then maybe you’ll forgive us for our past mistakes,
We can’t help that we eat plants, we just don’t eat steaks.

Now if you’ve been good this year,  go ahead and make a wish,
And each time you see one of us,   think welcome,  not banish.
And all of us creatures will give you our best shot,
To feed and nourish your garden with nary a thought.

So everybody listen carefully on Christmas Eve,
And maybe you’ll hear us and then you’ll believe.
You may even hear us exclaim as we prance out of sight,
" Happy Christmas to all, and to all a good night ! "

My thanks to Clement Clark Moore who wrote this poem in 1822 in New York.  I’d like to believe that he would enjoy my version for gardeners everywhere.
