Gardening Tips for August & IPM

I go out into my garden and look around daily. I pick basil for tonight's bruschetta, parsley for the potatoes and a few Sungold cherry tomatoes that don't make it into the kitchen but are eaten on the spot. I count 10 hummingbirds around my 3 feeders, the Ruby-crowned kinglets are scouring the trees for spiders and other bugs and the Wilson's warblers have found the thistle sock.

But what's this? Some of the fuchsia leaves and buds are curled, there are notches in the impatien balfourii and I see white furry things on the trunk of the crabapple.  The weather is hot one day and foggy the next. Better adjust my watering schedule, too. Whether you're seeing some of these same problems in your garden or have different issues that you don't know how to handle, here are some tips to help you decide what you can live with and what you can't.

Integrated pest management or IPM is a fancy name for common sense. By planting the right plant in the right place you can prevent most pest infestation. Pick your battles.Take action against insects only when they pose a significant threat to your plant.

Plants can usually survive with a little bug damage. Insects that are natural predators often will eventually arrive and handle your bug problem.  Picking them off by hand or spraying them off with water often works, too. Some vegetable plants may need to be protected with insect barriers or row covers. Simple traps for earwigs, slugs and snails are effective, too. Vacuuming is another method of controlling pests. Tilling the soil often disrupts the breeding cycle of insects like the rose slug. Encourage beneficial insects to visit your garden by planting a variety of plants. Use natural biological insecticides like Bt and nematodes that have minimal environmental impact.

If you feel you must spray for soft bodied insects like mites, choose insecticidal soap. This may sound strange but by not killing all the pests there will be some left in the gene pool that are not resistant to the organic or chemical sprays. Those left will dilute any resistant genes that appear.

Regular monitoring is the cornerstone of IPM. This is where that daily walk in your garden with a beverage comes in. You can see if a problem is getting out of control or not.

The fuchsia gall mite is one problem that I keep tabs on or the hummingbirds aren't happy. If your fuchsias aren't blooming and the leaf tips look curled up and deformed, your plants are infested with fuchsia gall mite.  First discovered on the West Coast in 1980 it is often mistaken for a disease because of the way it distorts and twists fuchsia leaves and flower buds.  The damage caused can be debilitating.  The leaves curl and distort so much that normal photosynthesis is disrupted and weakened plants fail to bloom  Infested plants usually recover if further mite damage is controlled.

Prune off all distorted foliage and buds.  This may be the best method of control as petroleum oil or insecticidal sprays need to be made every 4-7 days to disrupt the mite life cycle and will result in the mites becoming resistant. Neem oil is not recommended for use on fuchsia flowers.

There are several gall mite-resistant fuchsias, both hanging and upright, that are every bit as showy as the traditional fuchsia varieties.  if you have been plagued by fuchsia mites, try growing one of these instead. A list from Crescent City Fuchsia growers is available at http://www.ccfuchsia.net/ccfuchsia5.htm.

Lake Tahoe vs Santa Cruz Mts

Boy are we spoiled living here like we do. Our climate is just cold enough in the winter to grow delicious fruit that likes a bit of chill but not so cold that we're forced inside during those months. Our summers are warm and long allowing vegetable gardens to thrive as well as people.

Not so at Lake Tahoe where I recently spent some time. Here cold winters make snow sports reign supreme and summer brings a short growing season. Locals told me that their lilacs are just now blooming, the peonies are in tight bud and many gardeners don't bother growing vegetables. Late snow often in June and early snow sometimes in late August make gardening in the Sierra so much more difficult.

I visited a beautiful nursery in Tahoe City, the Tahoe Tree Nursery to get a feel for what's popular in these parts. This destination nursery is landscaped for weddings as well as bringing in perennials, trees and shrubs to sell from their growing grounds in Loomis in the central valley. Quaking aspen grew in lovely stands providing shade for ferns, hostas and ligularia.  Favorite perennials are echinacea or cone flower and were offered in all the hot new colors: Hot Papaya, Raspberry Truffle, Marmalade, Primadonna White as well as the beautiful magenta standard, Magnus. Many varieties of coreopsis, stachys, lonicera, rudbeckia, kniphofia and hardy geranium are also popular. Rugosa roses do well in this climate also.

On a hike to Shirley Lake in the Squaw Valley area the wildflowers were in full splendor. Fields of Indian paintbrush, mules ears, penstemon, lupine, phlox and delphinium and Mariposa lily covered the slopes. Early summer starts off this areas growing season and everything was lush with new growth and color.

In our part of the world, our early wildflower season is almost over but perennials and flowering shrubs are at their peak and need a bit of attention about now. Here are some tips of what to do in the garden in July.

Make sure vines have support. Some grow so fast that if you look away for a week they become a tangled mess. A little maintenance goes a long way in this department.

Trim back early flowering perennials to encourage the next flush of blooms.

Turn the compost pile often and keep moist.

Add additional mulch to planting beds to keeps roots cool and preserve moisture.

Check ties on trees to make sure they aren't cutting into the bark.

While your out in the garden, take some cuttings from favorite plants like roses, hydrangeas, geraniums, trumpet vine, blackberries, lavatera and salvia. Softwood cuttings are taken during the growing season from relatively soft flexible growth.  Gather 8-12" cuttings early in the day. Discard flowers, buds and side shoots. Then cut the stem into 3-4" pieces, each with at least 2 nodes. Keep track of which end is the bottom and dip in rooting hormone. Poke holes with a pencil in a rooting medium such as half peat moss or potting soil with half perlite, vermiculite, or sand or use perlite or sand only and insert cuttings. Enclose each container in a plastic bag to maintain humidity, opening the bag for a few minutes each day for ventiliation. Place the containers in bright shade.

Some cuttings take 4-6 weeks to root while others take longer. Once they have taken root and are sending out new leaves, open the bags. When the new plants are acclimated to open air, transplant each to its own pot of light weight potting soil.

Enjoy your garden even more this summer by rooting your own plants for yourself, to give away or trade. This is how early settlers filled their gardens, too.
 

Ahbkazi Garden – Victoria, BC.

How many beautiful gardens can one visit on one vacation? I spent a whole day at the spectacular Butchart Gardens on Vancouver Island. a couple of hours at St. Ann's Academy heritage garden and the lovely Empress Hotel rose garden is a nice place to watch the sunset over the harbor.  But I wanted more and on the outskirts of Victoria in a residential neighborhood I found the perfect garden.

Smaller and more intimate, Abkhazi Garden offers a fine example of what you can do with a large lot full of rocks and trees if you put your mind to it. Now owned by The Land Conservancy of British Columbia, the property was bought in 1946 by Peggy Pemberton Carter who recognized the possibilities on this last undeveloped lot in the neighborhood. This independent minded woman traveled to the west coast after WW II from a prisoner of war camp in Georgia, using funds she had hidden during the war in talcum powder. She married Prince Abkhazi, a Russian fellow prisoner, when he joined her in Victoria and they began to build the summer house and lay out the garden together.

Over the next 40 years, Prince and Princess Abkhazi  designed, planted and maintained the property. Peggy had lived in Shanghai before the war and it was this influence that plays out in the garden. Chinese gardens are essentially places of meditation, places to withdraw from worldly cares. This must have been very appealing to the Abkhazi's  after their experiences in prisoner of war camps. Nothing in a Chinese garden is hurried or blatant. Paths are not just a way of getting from one point to another, instead they are a way of exploring changing views that slowly shift as you walk through the garden.

As I made my way between massive glaciated rock outcroppings and under mature native Garry oak trees gorgeous views of the snow-covered Olympic mountains and the Straight of San Juan de Fuca could be seen.
Each garden "room" utilizes the natural lay of the land and has a welcoming bench for sitting and taking in the flowers. Lots of birds and butterflies were busy feeding and going about their daily activities.

Purple allium flowers the size of grapefruit caught my attention. Growing nearby, pale yellow Candelabra primula[/caption]Japanese iris bordered one of the paths. Fragrant dianthus, several varieties of campanula and euphorbia, lady's mantle and candelabra primula were all blooming and the weeping Crimson Queen Japanese maples were pruned to perfection.

More than just a collection of plants, this garden flows with the natural contours and blends the house with it's surroundings. it is a stunning example of West Coast design. The garden flows around the rock outcroppings, taking advantage of deeper pockets of soil for conifers, Japanese maples and rhododendrons. The original Lily-of-the-Valley beds still carpet a slope. Alpine plants are placed like little jewels around the boulders and woodland plants border the undulating lawns.

A small waterfall flows into a pond where 2 large turtles sunned themselves on the rock edge while a third rested on a waterlily pad, it's red ear markings picking up the dark pink color of the waterlily flower. A stand of stately white calla lilies emerged through a piece of drifwood near a resting spot. The garden is magical. One that you could imagine on your own property if you had the next 40 years to plant and maintain it.
 
It would have been  a terrible loss if the property had not been purchased in 2000 by The Land Conservancy. After the death of the Abkhazis the land was slated to become a townhouse development. This unique garden
is truly a place of wonder. a place to meditate and to withdraw from worldly cares.
 

Zauchneria & other Favorite Plants for the Santa Cruz Mountains

I don't have room for any new plants. Really I don't, but come spring I just can't help myself. Every pretty plant I see in a nursery or at a friend's house, I want. Admiring from afar just won't do. I rationalize that if I choose from plants that will do well in my specific environment then it's OK to add something new to the garden. If you want to be armed with a check list of possible new plants that are almost guaranteed to do well in your own neck of the woods and without a lot of water, here are some good choices.

For those who live in the sun, consider a brilliant red California fuchsia. Hummingbirds and butterflies are both attracted to zauschneria which starts blooming in summer and continues through fall. They provide a principle nectar source for hummingbirds though the hottest, driest season. Deer aren't interested in them, either.

Ghostly Red is one of my favorites for sunny slopes although it will grow in some shade and is tolerant of many soils including alkaline, sand, clay and serpentine. The foliage is grey-green and shows off the intensely red flowers. It grows about 1-2 feet tall which is tall enough to attract the hummingbirds but low enough to be neat and tidy. Each plant can spread to 5 feet wide.

Another good variety of California fuchsia is Everett's Choice. This fast growing groundcover has dark orange-red flowers on a low, spreading plant. Furry grey foliage creeps along the ground and looks beautiful next to a path or rock wall. It's drought tolerant but will look fuller with an occasional drink after it's established. As with all California fuchsia a hard winter pruning will produce a denser plant the following year.

Consider combining either of these grey-leaved California fuchsias with the new Black Adder phormium to make a dramatic statement in your garden. Black Adder was bred from the deep, deep brown Platt's Black phormium but its color is even more striking. Deep, burgundy-black leaves have a high gloss overlay which eliminates sun fading. Black Adder is a strong and healthy grower with an upright but not stiff architectural form. When mature it reaches 3 ft tall by 3 ft wide so fits nicely into the garden.

Originally native to New Zealand, phormiums are also known as flax and their hemp-like plant fibers were traditionally used by New Zealand's Maori people to make rope, baskets and cloth.

Other good companion plants for California fuchsia are Bee's Bliss salvia, Western redbud, rockrose, buckwheat, armeria maritima, deer grass and ground morning glory. Ceanothus, rosemary and manzanita also look good with California fuchsias.

Shady gardeners ( no, I'm not making a moral judgement here ) or should I say gardeners who live in the shade or have portions of their gardens in the shade, have lots of plants to tempt them. Favorite plants for dry shade include flowering currant which is so spectacular at this time of year. This shrub blooms with huge clusters of pink, rose or white flowers. Other plants that attract hummingbirds in bright shade are Western columbine, bleeding heart, heuchera and mimulus. You can find these in a rainbow of beautiful colors these days.  Humminbirds love salvia spathacea so much they're called Hummingbird flower. Also suitable for planting under oaks are Douglas iris. I love the white Pacific Coast hybrid variety, Canyon Snow. Their white flowers make an area under tall trees come alive.

A couple of new additions to the garden would be fun especially if they don't use up your water budget. With a little planning you can have color, attract wildlife and have water for the vegetable garden, too.
 

Tomatoes for the Santa Cruz Mountains

The spring sun has started to warm the soil. I'm already having visions of eating ripe, luscious tomatoes later in the season. I have several friends who are tomato fanatics and share their trials, tribulations and successes with me. Every year brings new hope to a gardener who is excited to grow the best tomatoes ever.

One friend who loves her tomatoes is going to finally start a gardening journal in a binder. With a page devoted to each of her tomatoes, complete with color pictures, seed grower descriptions and space for her own notes, this year her tomatoes just can't fail to be delectable.

During the last couple of years, cool spring and early summer weather  took its toll on tomato production and taste so this year she is trying some different types for cooler climates. Many of these tomato varieties originate from cooler growing areas in Russia and other northern growing areas. She chose from Alaska, Amber Colored, Anna Russian or Azoychka varieties that are all Russian heirlooms,  Alicante from England or Black Krim originally from the Isle of Krim on the Black Sea in the former Soviet Union. Of course, Black Cherry, the only true black cherry tomato, is on the list. With a description of "irresistibly delicious with sweet, rich, complex, full tomato flavor that bursts in your mouth" , who could resist?

This tomato aficionado planted out her early "tried and true" varieties that she started from seed in the ground the last week of March in Wall O' Water season extenders to keep them warm. Night time temps in March were pretty cold so they needed all the help she could give them. The regulars include Early Girl, Stupice, Carmello and Sun Sugar.

New seedlings she bought and recently planted include Purple Cherokee, Paul Robeson, Northern Lights, Black Plum, Green Zebra and Sunset Red Horizon. She is also trying "a Red Brandywine that didn't do well last year but if we are lucky enough to have a warmer season if may do better".  She is "looking forward to the addition of new colors ( green striped, black, purple, marbled orange and red)  and hoping to enjoy the nuances of flavor that accompany them".

Renee's Garden Seeds has lots of great tomato varieties available online at www.reneesgarden.com. One is a colorful trio of treasured heirlooms that consists of Black Krim, the glowing orange Sweet Persimmon and traditional Italian Costuluto Genovese. She offers a total of 13 varieties including  heirloom Camp Joy cherry as well as everybody's favorite Sungold. For containers, there's Super Bush and for that burger, Big Beef Beefsteak tomato.  I'd like to try a Chianti Rose or the Italian Pompeii plum tomato.

According to Renee's website, tomatoes are native to South America and were carried to Europe in the 1500's by the Spanish conquistadors. Southern Europeans began enjoying their fruits early on, but in England they were viewed with suspicion and grown as ornamentals only as they are members of the nightshade family. In this country, Thomas Jefferson grew tomatoes to eat although most Americans didn't start cultivating tomatoes for the kitchen until the end of the Civil War.

Hope springs eternal for a tomato grower. What tomatoes are you growing this year? What were your best producers in years past? I'd love to hear from you as the season progresses and I'll share this with readers later in the summer or early fall.
 

Trials & Tribulations of a Test Garden

While at the Watsonville Terra Sole Nursery recently, owner's John and Sherry Hall shared with me their experiences growing and experimenting with plants in their own landscape and nursery. From these personal trials, they decide what to propagate and sell in the small, independent nursery they operate on their property.

With a philosophy to share what they learn with their customers, they grow native and unusual plants and other drought tolerant plants that are adapted to our dry summer climate. Sherry told me that they grow their plants as sustainably as possible, hand pulling weeds and collecting snails by hand. They said they propagate and grow their plants without growth regulators or dangerous chemicals. I saw many birdbaths both in their own landscape and in the nursery. Sherry told me they encourage feathered friends like the Western Bluebird to live in the garden to eat bugs. It's a win-win situation.

Sustainable doesn't just get lip service at this nursery. They don't use labels on their containers making it easy to recycle them. And John makes his own succulent garden boxes from 100 year old barn wood. They looked awesome planted up with a collection of various succulents propagated in the greenhouse.

I commented on the hardy geraniums and other plants coming up through the gravel on the nursery floor. John and Sherry both laughed as they told me "it's the best place to propagate some of the plants. Our son works at a big grower nearby and can't propagate some of these plants even in his $10,000 greenhouse".

What were some of my favorite plants that I saw on the tour and which do they think are the best performers?  
In the test garden, a Lemon Fizz santolina, with foliage so brilliant it looked like a lit light bulb, nestled at the base of a burgundy phormium. A blooming euphorbia completed the vignette. Santolinas are drought and deer tolerant. One important thing Sherry has learned from the test garden is how close to plant things. "They get a lot bigger than you'd imagine from seeing them in that cute little gallon can".

They have an extensive coral bell or heuchera collection that they have been testing for the past 4 years. Starting with 80 plants of different kinds, 90% have survived. The fancy hybrids do need some summer water and compost to look their best. The variety Pinot Gris, with molasses colored foliage, really stood out among the rest.

The echinacea were just emerging from dormancy and will bloom during the summer.  They are very dependable in the garden unless the gophers get them, I was told. Agastache is another one of their favorites and the hummingbirds love them, too. They grow many colorful cordyline from clumpers to tall types. They are doing great, Sherry said. "Maybe a little too great" as they get big fast. Gaillardia have been disappointing but maybe they received too much water at the wrong time, she confessed.

In the nursery, I was drawn to the hardy geranium, 'Bill Wallace'. Loaded with purplish-blue flowers, this mounding perennial blooms for a long time. In another spot, I couldn't miss the rich, dark burgundy flowers of the camellia "Night Rider". "It's the only camellia we grow", the Hall's explained. A very slow grower, it's perfect for containers.

At the Spring Trials they bought a flat of a new acacia called 'Cousin Itt'. This plant is very different from the invasive tree we see blooming each winter. A well behaved 30" mound of soft, emerald green foliage it's drought tolerant and would look great near a dry stream bed.

With so many plants to talk about, we ran out of time and ended with the "under-used, under-appreciated" Beschorneria.  This genus of succulent plants belong to the subfamily agavoides and is native to Mexico. The Hall's are concentrating on propagating a variegated variety in their nursery. A tall blooming red spike had emerged from one of the green species.

This is just a taste of the many plants I learned about that day at Terra Sole Nurseries. From drought tolerance, disease resistance, cold and wildlife compatible the experiments continue.
