Garden Tips for March

Leave a comment

Spring is in the air. It’s always exciting to see the plants in the garden come to life. I’ve been invited to tour a  garden in Scotts Valley in April when many of the early flowering plants will be in bloom.  I’ve been to this garden before and there’s always an interesting tree, shrub or flower to enjoy.

One of my long term goals is to view the great gardens in the Santa Cruz Mountains. If you have a garden that you think others would like to hear about and you are willing to share it with me, please contact me. I’d love to spend time with you in your garden.

There’s so much to do now in the garden. If you are feeling overwhelmed here are some suggestions for the more important to-do’s.

* Check drip systems for leaks or clogged emitters. Flush sediment from filters and check screens for algae. You may need to add emitters if plants have grown significantly.

* Finish pruning and clean-up of trees, shrubs, vines and perennials. This includes fireblight die-back on pears, apples, hawthorn, pyracantha, photinia, crabapple quince and toyon., Prune out and discard diseased branches making the cut at least 6-8" below blighted tissue. Clean the pruning blades with alcohol or a 1:5 solution of household bleach to prevent spread of the disease. Also finish pruning and cutting back perennials and ornamental grasses. Go ahead and give grasses a 3-5" crewcut so fresh growth can emerge. Cut back old foliage of maiden hair ferns to allow new growth to take center stage. If you have Western sword ferns or another type that has winter or thrip damage, remove shabby looking fronds. Even if you have to cut back the entire fern it’s OK. It will regrow in just of couple of months.  Prune any other frost damaged plants when you see new growth begin.

* Spread fresh compost around all your plants. Good soil is the secret to successful gardening. The first principle of organic gardening is to feed the soil and it will feed the plant. Remember that all gardening used to be organic. Layer compost and or mulch on top of the soil and let it slowly decompose and filter down into the earth.

* As you plant new additions to the garden add organic matter to the soil. If your garden’s soil is sandy, organic matter enriches it and allows it to hold water more efficiently. If your soil tends toward clay, organic matter will loosen it up and improve drainage. In well-amended soil, plants grow deep roots, are hardier and more resistant to disease. Organic matter, such as compost, planting mix and well-rotted manure, boosts nutrition and improves soil structure.

* Fertilize if you haven’t already done so. Citrus, shrubs and fruit trees just emerging from dormancy are begging for their first meal of the season. Lawns begin their spring growth now also and benefit from a boost of nitrogen. You can also spread a thin layer of composted manure over you lawn. Leaving you grass clippings on the lawn will benefit it by shading the roots as it get warmer and as they break down they help feed it, too. Perennials benefit from both a fresh layer of compost or manure and a light application of balanced fertilizer. They respond to phosphorus especially in the spring for root growth, stem sturdiness and flower development. Wait until azaleas, camellias and rhododendron have finished blooming before feeding them.

* The most important to-do for March is to take time out and enjoy your garden and our beautiful surroundings. Those last few weeds will be there tomorrow but you’ll never get another today.

New Plants for 2011

Leave a comment

I know this gardening season isn’t over yet, but I’m already . Some are already being grown on a limited basis by the wholesale growers while others won’t become available until 2011. Recently I had the opportunity to view up-close and personal some of these new unique perennials, shrubs and grasses. It’s exciting to envision these in our own gardens.

It’s no secret our weather is just about perfect here. That’s why so many of the wholesale nurseries have operations in this county. They know the growing conditions are excellent here for annuals, perennials, grasses and woody ornamentals.

Many of the plants we buy start life as small plugs and liners. Some of these are produced in tissue culture labs located in places such as India, China, Guatemala and Holland. These are then grown on to sellable size by other wholesale growers before they eventually arrive at your local nursery. If you have a Black Mondo or carex grass or a cordyline, hellebore or heuchera it may have been started from a tissue culture somewhere on another continent and has more frequent flyer miles than you do.

Plant tissue culture consists of taking a piece of a plant, such as a stem tip, and placing it in a sterile ( usually gel-based ) nutrient medium where it multiplies, It’s similar to taking a cutting of your favorite houseplant and growing it to share with a friend. The production of plants in sterile containers allows the propagator to reduce the chance of transmitting diseases, pests and pathogens.

One of the new plants that I saw that really caught my eye is the grass,  Pennisetum Fireworks. The variegated pink striped blades of this grass are just as spectacular as the pink flower heads. Some gardens with clay soil and heavy frost in winter may need to grow this plant in a container but it’s worth babying this one, it’s so beautiful.

You may have bought a bright orange Begonia Bonfire this year and were impressed with the hundreds of flowers that it easily produced over the season. Well, next year you’ll be seeing the Sparkle series begonia which is similar. This tuberous begonia is nothing like the classic you are familiar with.  One plant will grow to about 24" in the ground or a container and depending on which color you choose, will be covered with scarlet, white blush, rose or apricot flowers.

And don’t even get me started on all the new mimulus colors that are going to be available next year. The Jellybean series comes in classic orange and gold but also red, purple, pink, light pink, lemon and terra cotta. Remember these are deer resistant, too.

Also there are new hummingbird favorite agastache flavors out now.  Picture in your garden, flower spikes in colors that look like fruit- grapefruit, apricot, grape and orange nectar.

I haven’t even touched on new introductions like Green Jewel echinacea or dwarf butterfly bushes in magenta, violet or pink. How about a bush form of the vine, Hardenbergia?  Meena will grow 36" tall and have purple flowers in winter.

Look for one of these new perennials next year. It’s going to be a colorful year in the garden.

Landscaping Tips for Great Gardens

Leave a comment

By this time of the year, you probably have planted some new perennials for color in your garden. But if you look around and still feel something is missing the answer may be that your landscape needs more than color. As a landscape designer I am often called upon for ideas to create richer landscapes that provide four seasons of interest. Here are some tips I pass along.

A more sophisticated appeal and enduring quality in your landscape can be achieved if foliage color is used to complement, or contrast with, other plants within the design. This technique unifies the overall look while offering appeal throughout the season. One plant that would make this happen is Rose Glow Japanese barberry. Their graceful habit with slender, arching branches makes a statement by itself but it’s the vivid marbled red and pinkish foliage that steals the show until they deepen to rose and bronze with age. In the fall, the foliage turns yellow-orange before dropping and bead-like bright red berries stud the branches fall through winter.

Abelia Confetti is another small shrub that can be used to unify your landscape. Growing only 2-3 ft high and 4-5 ft wide with leaves variegated white, their foliage turning maroon in cold weather. Abelias are adaptable plants, useful in shrub borders, near the house or as as groundcover on banks. White, bell-shaped flowers are plentiful and showy during summer and early fall.

Texture in foliage is very important in good garden design. Varying the size and shape of leaves creates diversity and variety among neighboring plants. Striking visual interest can even be achieved when working with two different plants with similar shades of green.

An example of this would be combining Gold Star pittosporum tenuifolium with grevillea noellii. The first has dark green oval foliage on 10-15 for dense plants while the latter is densely clad with narrow inch long glossy green leaves. Clusters of pink and white flowers bloom in early to late spring and are  a favorite of hummingbirds.

Using the same plant shape throughout a landscape can create and tie the entire design together. Forms and shapes of plants and trees can be columnar, conical, oval, round, pyramidal, weeping, spreading and arching. A loropetalum with its spreading tiers of arching branches could be repeated throughout your garden to create visual interest and balance. A dogwood tree could also repeat this same form as their branches grow horizontally.

Consider also layering plants to create a beautiful garden. From groundcovers all the way up to the tallest tree, natural looking designs mimic nature.

Don’t forget about focal points. This could be a Japanese maple cloaked by a wall of dark evergreens or a statue or pottery at the end of a long, narrow pathway. Focal points draw attention and even distract the eye from an unsightly view.

There are many solutions to make your garden complete. Consider using some of the above design elements to make your landscape beautiful.

New Plants for the Garden

Leave a comment

Every season new varieties of colorful flowering annuals and perennials are introduced by hybridizers. These new plants are field tested and bred for better performance, disease and insect resistance, flower size, color and heat tolerance.  Where does this happen?  What goes into that gorgeous vivid red geranium you see on the bench at the nursery?

Over 30 breeders of flower seeds and perennial starts each spring showcase their new varieties in trials held throughout the state.  Professional growers visit the trials to choose which new varieties they will grow this year and offer to local nurseries and garden centers.  Goldsmith Seeds in Gilroy is one of the locations that hosts the colorful spectacle.

Fragrant, wisteria-covered arbors shade paths that wind throughout the landscaped grounds . The grounds are open to the public to enjoy throughout the summer.  Also on site are the greenhouses where breeders work on creating new and better flower varieties.  It was interesting to see several acres planted with fava beans as a cover crop. Soon the fields of this flowering legume will be cut down and tilled into the soil to add nitrogen. Legumes attract soil dwelling bacteria that attach to the plant’s roots and pull atmospheric nitrogen out of the air and soil, storing it on the roots as nodules.  When the plant is cut down and chopped up to decompose that nitrogen remains in the soil to feed new plants. After a few weeks of decomposition the energized soil will be ready for planting test flowers that Goldsmith seeds will further evaluate.

All of the seeds are actually grown in greenhouses in Holland and Guatemala. Cool season flowers like primroses, cyclamen, violas and pansies are produced mainly in Holland while warm season flowers like dahlias, geraniums, gazanias, and verbenas are grown at different elevations in Guatemala. I learned Goldsmith Seeds has been developing and growing seed in Guatemala for 40 years.

What new cultivars really impressed me at the trials?  There’s a new geranium that combines the best features of ivy and zonal geraniums. I liked the amazing color of Calliope Dark Red but all the colors were show stoppers. They would be perfect for baskets or beds in full sun or part shade. And you should see all the colors that calibrachoa now comes in-light blue, dark blue, deep yellow, peach, orange, even white with rose veins. These have now been bred to bloom earlier in the season which is why you’re seeing them in nurseries now.  There were many fragrant flowers like . I always looks forward to them when they arrive at the nursery. 

Try something new in your garden this year. There are so many good choices.

Planning this Summer’s ‘Staycation’

Leave a comment

Picture yourself this summer with your family outdoors  during your  "staycation" – relaxing, cooking on the barbie, entertaining, playing with the kids or maybe just reading in the shade. Maybe you need to make some changes to truly have a relaxing backyard.  Now is the perfect time to plan while the yard is still a bit bare and you can see the space for what it really is.  Here are some ideas to get you started on your backyard makeover.

Make sure you have enough shade in your garden to keep everyone comfortable in the hot summer. We usually get a heat wave in May so be prepared early.  National Arbor Day in the last week of April but each state sets its own day of celebration. California celebrates this week, March 7-14, as the week to plant a tree.

There are so many good choices for our area.  First, determine how wide and tall you want your tree to grow. Next, know your soil and growing conditions.  Those who live in sandy areas might consider a strawberry tree, chitalpa, crape myrtle, Grecian laurel, fruitless olive, Chinese pistache, Purple Robe locust, California pepper tree or native oak.  Good choices for those who live with clay soil are arbutus ‘Marina’, western redbud, hawthorn, gingko, Norway or silver maple.  If you have quite a bit of shade but still need a bit more for the patio area, think dogwood, strawberry tree, Eastern redbud or podocarpus.

What would entice everyone out to the backyard after dark when it’s cooler? How about a simple metal fire bowl set on gravel, with brick or pavers?  If a piece of crackling firewood throws any sparks, they fall on the the gravel and expire.

How about a hidden getaway to read or just sit and relax? All you need is a quiet nook carved out of the larger garden.  Place a comfortable chair or love seat on some flagstone pavers, add a table and a dramatic container planted with flowers or colorful foliage and your retreat is complete.

After you’ve planted your tree and planned your hidden getaway take advantage of the moist soil to fertilize your garden .  Lawns and groundcovers are beginning their spring growth spurt and new leaves on trees, shrubs and perennials are starting to emerge. Spread compost, manure, or organic fertilizer to help plants get off to a strong start.  If you need to move any plants in the garden, now is a good time.  Plants are full of growth hormones and recover quickly from transplant shock. Pull weeds regularly before they set seed. They pull out easily from moist soil. Think of weeding as free gym time. The last frost of the season is approximately March 15th.  Spring is on its way.

    PROMISE YOURSELF  to be so strong that nothing can disturb your peace of mind.
    To talk health, happiness and prosperity to every person you meet. 
    To make all of your friends feel that there is something in them. 
    To look at the sunny side of everything and make your optimism come true.
    To think only of the best, to work only for the best and to expect only the best. 
    To be just as enthusiastic about the success of others as you are about your own. 
    To forget the mistakes of the past and press on to the greater achievements of the future.
    To wear a cheerful countenance at all times and give every living creature you meet a smile.
    To give so much time to the improvement of yourself, that you have no time to criticize others.
    To be too large for worry, too noble for anger, too strong for fear and too happy to permit the presence of        trouble.

 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.
