Fall Color Trees for the Santa Cruz Mountains

Walking around my neighborhood I see neon red fall foliage at every turn. Japanese maples covered with vivid red, bright orange or yellow leaves steal the scene wherever they grow. Surrounded by greenery Canadian redbud now pop with burgundy and yellow color. Flowering dogwood look like they're on fire. Because we live among so many trees and shrubs that stay evergreen in winter, fall color is especially important for us. What plants put on a good show in our area?

We are all familiar with the brilliant fall color of Japanese maples. Bloodgood is probably the single most popular upright purple-leaved variety seen in gardens. Beautiful in color and form, it's easy to grow and fits nicely in the smaller garden. Mine is covered with glowing red foliage now even though it grows year round in the shade.

My Coral Bark Japanese maple has had glowing golden and red foliage since early September. It's one of the earliest to start coloring in fall and make quite a statement in the garden when combined with warm-toned plants like heauchere 'Creme Brulee'.  I love this tree as it grows more upright and looks great near an entry as an accent. That luminous spark of lighter color is beautiful next to the deep reds of the other trees.

I surveyed some fellow designers for their favorite fall color varieties and found another Japanese maple favored not only for fall foliage color but the purple leaf color maintained during the summer even in hot situations. Called Red Emperor it's a moderate grower to 15 ft tall and wide. Like other Japanese maples it needs regular watering-weekly or more often in extreme heat especially during the first growing season to establish a deep, extensive root system. Watering can be reduced after establishment. Keeping mulch over the root zone is vitally important in our hot summers. Japanese maples look dramatic when planted with Japanese Forest grass, deer fern, flowering cherry and coral Bells.

Another favorite of mine for fall color is Crape Myrtle. You see them covered with large, colorful flowers starting in summer and lasting through fall. They are planted everywhere for good reason. Easy to grow and fast growing they take heat or cool coastal conditions. They are not fussy about soil and ask only for deep but infrequent watering. As if the flower color weren't enough to attract you, they absolutely glow in the fall with shades of red, orange and yellow. I'm partial to purple flowers so varieties like Catawba, Muskogee and Zuni top my list. Watermelon red and other bright red flowering varieties are also popular.

A great tree for the gardener interested in edibles is the Fuyu persimmon. This beautiful small tree is ornamental with glossy green leaves and also offers a dramatic fall display in shades of yellow, orange and red. Bright orange fruit begins to develop in late October and clings to bare branches usually through December. The tree looks more like it's covered with holiday ornaments than fruit.

Chinese pistache is a good tree for a patio, lawn or streetside. They can get by with almost no water but will tolerate lawn watering if drainage is good. Luminous orange to red fall foliage color is reliable even in mild winter areas. They are usually grown from seedlings.  When you buy one, it might be either male or female but a male tree without berries will develop better color.

Other trees with vivid autumn color that also do well in our area include red maples like October Glory and Autumn blaze, liquidamber, ginkgo, ornamental pear, cherry or crabapple, dogwood, goldenrain, locust, katsura, oak, redbud, sumac. All add to the fall drama of the landscape.
 
Now through late fall is a good time to shop for trees that change colors because you can see in person just what shade of crimson, orange, scarlet or gold they will be. I'm off to the eastern side of the Sierra to see for myself the Black oak and Quaking aspen fall color.
 

Fall Wildflowers & October to-do’s

Above the clear turquoise water of the Big Sur coastline, wildflowers still bloom in October. Bright orange Sticky Monkeyflower meander among a carpet of rosy blooming California Buckwheat. Deep orange California fuchsia flower on hillsides alongside the bright white flower heads of yarrow. They make a striking combination. Under the partial shade of pine trees lavender Seaside Daisy explode with color. Even poison oak contributes deep rusty-red tones to the landscape making it easier to identify and avoid. This wild land offers lessons and ideas to make our own gardens more beautiful.

Big Sur has areas of chaparral, oak and pine woodlands, riparian or streamside woodlands and redwood-tanbark-oak woodlands. Nearly half of all the flora of California grows here and many northern and southern California plants mix in this unique location. . Only in Big Sur will redwoods and yuccas thrive together. The look is startling. Certainly not a combination you would think of for your own garden.

Near McWay Falls on Hwy 1, fragments of an elaborate stone house still remain along with some of the landscaping. Christopher McWay and his wife Rachel settled the area in the late 19th century.The land passed through several owners until former U.S. House of Representative Lathrop Brown and his wife Helen acquired it and built a beautiful stone structure overlooking McWay Cove. The house was torn down 50 years ago but many of the landscape plants still thrive after all these years.  Hardy pittosporum eugenoides have survived without any supplemental watering. A huge stand of blooming Naked Ladies covers the rocky slope. We all know what survivors these bulbs are. Tall Mexican palms and ornamental trees surround the fragments of stone staircases and walls reminding us that nature will endure.

What allows all plants to thrive in their environment is the simple set of conditions that they like. It's nearly impossible to grow ferns in the hot sun around here and don't even think about trying a California fuchsia in the shade. Soil is important, too. Rich, moist soil is perfect for wild ginger but gravelly, well drained soil works best for Five-fingered ferns. Match the right plant with the right spot and you'll have success every time. Big Sur is a chock full of success stories.

Here are more tips for early fall in the garden.

Fall is not a good time for major pruning.  Wounds heal slowly, leaving them more susceptible to disease.  As a general rule, don't prune when leaves are falling or forming.  Wait to prune most trees until late in the dormant season or in late spring after leaves and needles form.  To avoid sap flow on birches and maples, prune after leaves mature.  

Do refresh perennials, such as butterfly bush, salvia and yarrow by cutting a third to half of their growth.

Rake leaves– compost or put in your green can. If large leaves are left in place they will mat down and set up fungal problems come spring.
 

Fall Blooming Perennials

Every garden changes over time.  Gardening is a process, a constant experiment so don't get discouraged when things don't go exactly as planned. For example, a cool spring may cause some things to bloom later while a warm, dry winter speeds up plant and flower development. Maybe that pink flowering tree now conflicts with the red blooms nearby. Whether it's caused by climate change or just the weather, take comfort that your garden can grow more beautiful each year with a little tinkering now and then.

At this time of year look to the following plants combined with ornamental grasses coming into bloom to carry your garden until autumn color from trees and shrubs kicks in. Go for dramatic extravagance with color combinations than inspire.

Russian sage.  Tall, airy, spike-like clusters , create a lavender-blue cloud of color above the finely textured gray leaves. This perennial has a long blooming season and the cool color of the flowers is stunning in the fall garden. There are several varieties available with different shades of soft blue to violet blue flowers. Most grow 3-4 ft tall. Little Spire Russian sage is a shorter, upright selection that doesn't flop over in the landscape. It adds a sense of lightness to the garden. You'll love the cool color on a hot day.

Aster x frikartii 'Moench'.  The lavender-blue flowers on this perennial can get 3" across and cover the plant with blooms from early summer to fall, even longer in mild winter areas if spent flowers are removed. They attract butterflies and make a good cut flower. This reliable, drought tolerant plant thrives in full sun, grows 2- 3 ft tall and is mildew resistant.

Agastache which is also called hyssop attracts hummingbirds, butterflies and bees to your garden It's also deer resistant. Aromatic foliage on Blue Fortune smells like peppermint-lemon when brushed or crushed. The flowers on Electra are vivid orange. Then there's licorice mint hyssop, orange hummingbird mint hyssop, anise hyssop and a whole slew of hybrids of every color in the rainbow- lavender, pink, apricot, orange, purplish, coral, powder blue, tangerine, red – you name it. Agastache is easy to grow in full sun or partial shade and is drought tolerant. Just be sure to provide excellent drainage.

Salvia-  the workhorses of the garden. Their long blooming season makes them right at home in the fall garden. There are some 900 species of salvias.  They are the largest genus in the mint family. Choose from many new cultivars like Dancing Dolls with rose and cream colored flowers. Another good choice is a Ca. native hybrid called Starlight that blooms with long white flower wands that really stand out at twilight.
There are lots of Salvia greggii varieties available such as Pink Frills, Golden Girl and Neon Dancer which has vivid rose and red flowers.  Salvias are drought tolerant and deer resistant (really). Although they tolerate some shade they looks best when planted in full sun. To encourage repeat bloom trim off spent flowers stalks when they start to look rangy. They will rebloom for months.

Another common plant from this huge family is the Mexican bush sage.  So showy that people mistake them for huge lavender plants. They are vigorous and upright growing to 3-4 feet tall and as wide.  Velvety purple and white flowers cloak foot-long stems. Salvia Santa Barbara is a compact selection that grows 2-3 ft high and spreads 5 ft wide. They stop blooming only when frost hits them.  To limit plant size and renew flowering stems, cut back close to the ground before spring growth begins.  You can't go wrong with these plants if you have a large space to fill.  Hummingbirds love them, too.

Perennials should be planted in multiples, not only for beauty's sake but also for lower maintenance. Let your trees and shrubs lend structure and year round interest with an explosion of perennial color that gets all the attention. Just don't hesitate to change what needs adjustment or transplanting if needed to a better location.

Fall Lawn Care & Candlestick Park

I attended the first Forty Niner home game of the season thanks to my Aunt Rosemary. I'm a Niner "Faithful" but it sure is fun to be on the winning side after so many years. At the football stadium everything seems really bright and colorful. I'm always amazed at how lush and green the field looks. How do they do that?

If you have a small lawn you can appreciate how the caretakers at Candlestick Park accomplish this. Be grateful you don't have 110,000 square feet of grass that is replaced annually. In some years, due to inclement weather of abnormal wear-and-tear, the sod may be completely replaced a second time near the end of the football season. The grounds crew mows the field every day to encourage the grass to continue growing and remain vigorous and they fertilize approximately every 10 days. The sod they use is called Tiffway II Bermuda which is a hybrid of bermuda with perennial rye.

The Forty Niners will be moving to the new Santa Clara stadium next year and it also will have a natural grass fieldGreen technology will be a top priority. The landscape and field will be irrigated with recycled water and a green roof constructed on the roof of some of the suites. I don't know now which type of turf they will plant but it'll be interesting to see what they choose.

At your own home, fall is the best time to feed your lawn for winter hardiness and robust growth come spring. Grass stores nutrients in the roots to carry it over the winter months, so apply a generous application of organic lawn fertilizer.
Your lawn will need the phosphorus to encourage deep, strong roots for winter.

Over time, soil becomes compacted, especially is areas that get heavy use. Consider aeration that opens up the spaces in the lawn to allow water, nutrients and air to get to the roots, making it thicker and healthier. It also helps drainage and water runoff. There are aerators for every size job just make sure it's a core aerator that removes the core of soil rather than just punching narrow holes in the ground. Once aeration is complete, it's the perfect time to top dress the lawn with a half inch of organic compost..

If you can see patches of bare soil in your lawn, it needs to be over-seeded and fall is the perfect time to do this. Over-seeding helps make lawns full and dense, keeps weeds down and helps prevent disease. First remove any thatch- that layer of dead grass and debris that settles on the soil. To loosen the thatch, use a stiff-tined rake or rent a power de-thatcher for large jubs. Then simply rake it up and recycle it.

Just before over-seeding, mow the lawn at the mower's lowest setting and rake the surface clean. This allows the new seed to have better contact with the soil for good germination. Water often and never let the seed dry out. After the new grass blades have had a while to grow, you can mow the lawn at the mower's highest level. This minimizes the stress on the young grass blades as they settle in. Also keep debris off the area so the new blades can absorb as much light as possible.

This is also a good time to plant a new lawn either from seed or sod.  There really is no other surface that kids can play on that is as durable. There are lots of choices for low water types, including the variety that Candlestick park uses. Other common grass mixes are blends of dwarf tall fescues.  If you train your lawn in late spring to encourage deep roots most lawns don't need as much water as we think come summer.

Be sure to amend your soil first with plenty of organic matter rototilled 6-12" deep. Skimp on this step and your new lawn will look great usually only for the first season. Like sowing wildflower seeds, you need to first get rid of existing weeds and their seeds.  Also incorporate a pre-plant fertilizer raked in the top few inches of soil to get your new lawn off to a good start.

If you need a small lawn, take care of it this fall and make it as healthy and drought tolerant next spring as possible.
 

Gardening with Children

The other day a young girl asked me, "Are you the lady that writes the flower column in the paper"? I was thrilled to know that my readership includes middle schoolers.  Our conversation soon turned to vegetables. Which are good to plant at this time of year and how late can they be started. Gardening can be a wonderful learning opportunity for all of us but especially for children.

In a garden, children can breathe fresh air, discover bugs and watch things grow. And, of course, a garden offers kids and everyone else fresh, tasty homegrown food. What better place for kids to play than in a place where they can use their hands and connect with the earth? Where else can they make a plan for a plot of land and learn the lessons of hope and wonder, suspense and patience and even success and failure? In a garden you can have conversations about life and even death in a way that doesn't seem so sad.

With the school year just starting, now would be the perfect time to encourage your child to grow something, keeping track of the progress by pictures and notes. Their daily actions really can make a difference for a sustainable future. Maybe what they learn could even be used for a school project. Here are some ideas.

September is the perfect time to start cool season vegetables. Carrots are fun to start from seed as they can be harvested even when small. For flavor it's difficult to beat a Nantes.   Nantes Coreless or Little Finger are two popular varieties.  They're not a carrot you'll find in the grocery store because they're difficult to harvest commercially and don't store well.  Both are juicy and sweet.  Nantes coreless grows to 6-7 " long, is blunt-tipped and fine grained.  Little Finger is unmatched for snacks, pickling or steaming.  It grows to just 3-4" long and is ideal for container gardening. too.

Red Cored Chantenay has broad shoulders and strong tapered tips.  This wedge-shaped carrot is also rarely grown by commercial growers.  For the home garden it produces 6" long carrots that keep well when left in the soil, store well after digging and are sweet and crunchy.  They perform well in heavy soil, too.

Danvers Half Long are another variety that are tasty raw, cooked, or juiced. They are one of the best carrots for storage as they stay crisp.  Carrots found at the super market are usually Imperators just so you know.

You can still start peas, beets, spinach, arugula, mustard and radish now from seed but it's better to start other veggies like lettuce, chard, broccoli, cabbage, cauliflower, kale, onions, leeks and brussels sprouts from starts. If your veggies haven't gotten a good start before the soil cools, they'll just sit there until spring. Remember to rotate your crop locations so insects  and diseases don't cause problems. Also be sure to amend your soil with compost to replenish the nutrients that have been used by your summer veggies and flowers.  

Flowers in winter are always welcome so I like to plant early blooming types of sweet peas at this time of year. These varieties flower in the shorter days of late winter. Winter Elegance and Early Multiflora are common early flowering types. Also plant some of the more fragrant spring flowering heirlooms and Spencer's at the same time to extend your harvest time. My very favorite sweet pea with long stems for cutting and an intense fragrance is called April in Paris. Large ruffled blossoms are a soft primrose cream, tinted at the edges in dark lilac that deepens and increases with age. You can't go wrong no matter what color or style sweet pea you choose. They are all beautiful.

If you grow roses fertilize now to encourage another round of blooms.  A well-fed rose not only rewards you with beauty and fragrance but can stay healthy and resist attack from insects and diseases.   Roses grown in sandy soil or containers need more frequent feeding than those grown in loam or heavier soil.  Make sure the soils is moist before fertilizing and water well afterward.

Whatever you grow, include the kids in the garden. It's a free and fun activity.
 

Good Shrubs for Erosion Control in the Santa Cruz Mtns

You know fall is just around the corner when you hear thunder. Seems like summer just started but now plants like lilac, rhododendron and dogwood have already set flower buds for next year. We don't know exactly what winter will bring. Will we receive lots of rain or a meager amount?

The latest from the Climate Prediction Center for the San Francisco Bay Area 2012-13 rainy season is that a mild El Nino event may be setting up. There has been a  weakening of the positive sea surface temperature in the Pacific. El Nino has been known to come with plenty of rain for our area. We are still in a wait and watch mode.

Long range outlooks for the fall from the CPC run from equal chances for above or below normal rainfall to a slight tendency toward below normal. For the November through January period the probabilities start to shift and a slight chance of above normal rainfall creeps up along the coast from the south.  By the time we get to the December through February period, the outlook is for above normal precipitation for the whole state with significant above normal chances for the Bay Area.

This is not a forecast but an outlook for the probabilities of above or below normal precipitation. If we do get heavy rains in January or February you should be prepared. Do you have a slope that might have an erosion problem?  Now is the time to start planning and planting. The nights are cooler, the days shorter, the soil still warm. Everything that a new plant needs to get a good start.

What plants are good for controlling erosion in our area? When choosing plants to cover a bank for erosion control, assess the conditions of the area you want to plant.  Is it in the sun or shade?  Is it a naturally moist area or dry?  Do you intend to water it or go with our natural cycle of wet in the winter and dry in the summer? Matching the plant to the site conditions will ensure success.

When designing a plant layout I consider whether I want a sweep of the same plant or a tapestry effect with a variety of plants.  Using more than one type of plant allows me to work with contrasting foliage adding pattern to my composition.  To create a stunning combination choose 5 or 6 styles and repeat them in small drifts to carry the eye through the composition. Add grasses for linear texture.

If the area you need to stabilize is large and mostly shade, consider Ribes viburnifolium aka Evergreen Currant which grows 3-6 ft tall spreading to 12 ft wide. It needs no irrigation when established. Another plant that tolerates shade and needs no irrigation after 3 years is Mahonia repens aka Creeping Mahonia. It grows 1 ft tall by 3 feet wide spreading by underground stems that stabilize the soil.

Symphoricarpos aka Common Snowberry or Creeping Snowberry can hold the soil on steep banks. They tolerate poor soil, lower light and general neglect. Philadelphus lewisii aka Wild Mock Orange tolerates some aridity and partial shade. This beautiful, fountain shaped, fragrant flowering shrub grows about 8 ft tall by 8 ft wide and is not fussy about soil.

A bank in the sun would contain a different plant palette. Some of my favorite plants to control erosion in this situation include Ceanothus in all its forms. Groundcover types like Centennial, Anchor Bay and Maritimus are not attractive to deer like the larger leaved varieties. Rockrose such as Cistus purpureus also provide large-scale cover for expansive sunny areas.  Their dense strong root systems helps prevent soil erosion. Choose from white, pink or magenta flowers on plants varying from 1-5 ft. high depending on which variety you choose. This Mediterranean native is fast growing, drought tolerant and deer resistant.

Smaller plants for color that control erosion are lavender, California buckwheat, salvia leucophylla, California fuchsia, deer grass, needle grass, mimulus, yarrow, Pacific Coast iris, bush poppy, penstemon and artemisia.

These suggestions are just a few of the plants that control erosion. Every area is different and every situation unique. Email me if you would like help with your area.
