Lessons from Butchart Gardens and the Pacific Northwest

Leave a comment

I can see snow-covered Mt. Rainier from my sister's deck. Last night a rainbow bridged the Puget Sound which flows around Fox Island at the southern end of the sound. The landscape here is lush and green. Dogwoods, foxgloves and rhododendrons are still in full bloom. This temperate rain forest receives more rain than ours but I see many of the same woodland plants that we grow. I study each garden for new ideas.

The next day we head for Vancouver Island. As the clouds clear the Victoria Clipper pulls into the harbor. The Empress Hotel's landscaping is picture perfect. Purple rhododendron, hosta, and hellebore grow under the white Kousa dogwood trees. Late afternoon sun backlights each leaf. Gingko trees and weeping birch frame the Parliament building. The lights come on and outline each gable and tower. Still exploring the city later I look at my watch. It's after 10pm and still light. I forget we are closer to the land of the midnight sun at this latitude.

Visiting gardens is always the highlight of all my trips.  Butchart Gardens, a National Historic site of Canada, is a prime example of quarry restoration. Huge 100 year old poplar trees with gnarled trunks frame the famous sunken garden. Throughout the perfectly manicured lawns perennial beds grow oriental poppy, Japanese iris, Asian lily, hosta, black mondo grass, black-eyed susan, and lady's mantle. This kind of perfection comes with a price. We saw several gardeners raking and deadheading while several others cleaned around the stone border with pastry brushes.

Victoria is famous for its hanging baskets. At Butchart Gardens several hundred hand from every arbor, trellis, pergola and shepherd's hook. Mixed baskets of long blooming annuals and perennials are started early in the greenhouse then brought out in full bloom. One of my favorites featured peach-toned tuberous begonias, trailing sapphire lobelia, bacopa and coral calibrachoa. I was drawn to the dozens of hanging fuchsias and a rainbow of begonias planted with columbine, ferns and gold acorus grasses.

It must be fun to plant up the large pots that decorate the grounds. Even the wooden recycling receptacles have mixed planting on the top. Several noteworthy pots were planted with orange flowering maples paired with blue Mexican poppies and a variegated geranium. Another we liked contained a striking Electric Pink cordyline, coral petunia, calibroachoa and Bonfire begonia.

Fragrant flowers entice the senses and are planted everywhere. Strolling through the garden, vanilla scented heliotrope greet you. Spice-scented stock is planted nose high atop rock walls. Mrs. Butchart started this tradition and the garden strives to have something fragrant blooming every season of the year.

The roses were just starting to open. Many of them originated in England and Australia. The Queen's Pink peony Golden Jubilee was honored with decorative flags hung from the light posts. Flanked my tall gorgeous blue delphiniums it was quite a sight.

If it was early for the roses, the peony did not disappoint. I have never seen so many in one place. This climate is perfect for their culture. I had a hard time deciding which was my favorite. Double deep burgundy flowers grew alongside soft peach and bright pink ones. A cool white one paired well with Bridal Veil spirea. A soft peach variety looked great with the darker orange oriental poppies.

Always on the lookout for planting ideas, the endless vignettes were inspiring. The many different garden rooms in this garden allowed for countless combinations. One that caught my eye paired a purple smoke bush with coral verbascum and the variegated iris pallida. The blue flowers of the iris contrasted perfectly with the coral flowers and burgundy foliage of the other two plants.

I saw this garden in a new light on this visit. It was spectacular. Next week I'll recount my visit to Abkhazi Garden outside Victoria.

January To-Do’s for the Santa Cruz Mtns

Leave a comment

A new year in the garden. I'm already starting to make journal entries for January. Not much to shout about in the weather department. We've had dry Decembers before but if January turns out to be the start of 6 weeks of Caribbean-like weather like last year we'll never catch up.

The weather affects how things grow as much as the soil that plants grow in. Remember the cool spring and summer we had while you waited for your tomatoes to ripen? I was just looking at the weather forecasts for 2010 that the Farmer's Almanac predicted. Last May when I first wrote about them they were way off for the first half of the year and at best were hit and miss for the latter half. October did bring rain for us as predicted but they hedged their bets for November calling for "bands of showers" off and on during the month. December for us brought lots of frost and a heavy wind storm.  Although the frost was predicted by the Almanac, I didn't see any "light to moderate rainfall" in December. I put my trust in the satellite map, internet weather sites and my own common sense to judge when to start planting, pruning and transplanting for the season.

This year I'm going to start off right by noting on my calendar at the beginning of each month just what I need to do to ensure a happy, healthy garden.

Here are the tasks to do in the garden in January:

  • Plan for spring. Bareroot fruit, nut, berry and ornamental season runs through the end of February. Don't miss this inexpensive way to add to your edible garden or your landscape.
  • Cut back hydrangeas if you haven't already done so. Apply soil sulfur, aluminum sulfate or other acidifier if you want to encourage blue flowers. You must do this before they set flower buds or it won't help.
  • Prune fruit, nut and shade trees and spray with horticultural oil, lime sulfur, liquid sulfur or copper dormant spray. You should get one more spraying in about Valentine's Day. This is actually the most important one as it's just before bud break. Don't use lime-sulfer on apricots, though.
  • Cut back summer flowering deciduous shrubs and vines.  Don't prune spring flowering varieties like lilac, flowering cherry, plum and crabapple, rhododendrons, azaleas, camellias, weigela and spirea until after flowering but you can cut some during flowering to bring in for bouquets.
  • Control overgrown honeysuckle, potato vine, morning glory, trumpet creeper and pink jasmine by thinning now or even cutting back low to the ground if  they are a big tangled mess.
  • Prune roses towards the end of the month. I'll tell you how to do this later but it's not as hard as it sounds.
  • Bait for slugs and snails

And here are the tasks you should not do in January:

  • Don't cut back grasses yet if you get frost in the area where they grow.
  • Wait to prune back perennials that may have their new foliage damaged in a late frost
  • Wait until February to prune frost  damaged shrubs  if you can tell how far down the die back goes otherwise wait until growth starts in the spring.
  • Wait to prune fuchsias and other perennials until February.
  • Don't fertilize houseplants until March. Because they are resting at this time of year, they use little water.  Don't overwater.  Be sure they are dry before watering.

As always, if you have any questions, feel free to email me. I'd love to hear from you.

Saving Trees by Removing Ivy & other tips

Leave a comment

Well, it’s that time of year again when all things seem possible. Hope springs eternal –  the spring will be warm and the veggies will get off to a good start this year. That torrential rains won’t knock off the fruit blossoms and that all will be right with creatures big and small.  The narcissus are blooming already signaling the start of the new season.

An important thing to remember is that garden is a verb as well as a noun. It’s the act of gardening that’s important not so much what your garden looks like. So relax a little and enjoy it. With that in mind here are some tips to improve the health of your garden.

I received an email from a reader asking that I please advise people to save the life of their trees, including redwoods and oaks, by removing the ivy that grows up the trunk. Ivy can kill trees by tightening its hold on the trunk while both of them grow and can eventually stop the supply of nutrients and water from the roots to the branches. Trees supporting heavy ivy growth can be uprooted or broken by wind. The environment ivy creates is also harmful to trees. It keeps moisture against the bark of the trunk, creating a state of constant wetness which attracts insects. It covers up any developing problems with the tree. Many tree diseases and decay became major problems because they were hidden by ivy growth.

If you have a tree with a lot of ivy coverage, there are a few simple steps you can take to remove the ivy. Go around the tree and cut out a vertical section of ivy about 1-2 feet wide around the entire tree. A large screwdriver or forked garden tool can be used to pry and snap the cut section away from the trunk. The lower portion of ivy will need to be pulled and cut off periodically to prevent further growth from the base. The upper ivy will die on its own and can be removed much later when it’s easier to pull.

What else should we be doing to enjoy our gardens more?
    Use plants that bloom over a long season, have colorful leaves and attractive bark and berries.

    Garden on a small scale using containers and small, easy to manage plots for organic vegetables, flowers     and herbs.

    Add low voltage, LED or solar lighting so you can use the garden after dark.

    Furnish your patio during the warm season with pots, furniture,a fire pit and a patio heater.

    Add water to your garden with a small recirculating fountain or pondless waterfall.
gold, chartreuse, variegated or burgundy colored foliage in the     garden. Abelia Kaleidescope paired with Purple Smoke tree is one of my favorite combinations.  A combo     to try for the shadier parts of the garden is Black mondo grass with white variegated Jack Frost brunnera.     Look at your garden as a series of small vignettes and pair new plants together you haven’t tried before.
    Go through one of your seed catalogs and see what’s being offered in these tones.

Remember that garden is a verb as well as a noun. It’s the act of gardening that’s important not so much what your garden looks like so don’t sweat the small stuff.

National Arbor Day 2010

Leave a comment

National Arbor Day was founded by J. Sterling Morton in 1872 and is celebrated on the last Friday in April. This year it falls  on April 30th.  The simple goal of this day is to inspire people to plant, nurture and celebrate trees.  So whether you’ve been thinking about planting a fruit tree to feed the family, a shade tree to save on summer cooling, a flowering tree to attract pollinators, or some trees to hang the hammock on this is a good time to plant as well as nurture and celebrate all trees.

Trees are remarkable in how they grow and adapt to their environment.  Some trees, like crape myrtle, sycamore, madrone and cherry have especially beautiful bark. This is the tree’s protection from the outside world. Continually renewed from within, it helps keep out moisture in rain and prevents the tree from losing moisture when the air is dry. It insulates against cold and heat and wards off insect enemies.

The inner bark, or phloem, is the pipeline through which food is passed to the rest of the tree, It lives for only a short time, then dies and turns to cork to become part of the protective outer bark.

The next layer in is the cambium cell layer which is the growing part of the trunk. It annually produces new bark and new wood in response to hormones that pass down through the phloem with food from the leaves.  These hormones are called auxins and stimulate growth in the cells.  They are produced by leaf buds at the ends of branches as they start growing in spring.

Inside the cambium layer is the sapwood or xylem which moves water from the roots to the leaves. Sapwood is new wood. As newer rings of sapwood are laid down, inner rings lose their vitality and turn to heartwood.

Finally, the central supporting pillar of the tree is called heartwood. Although dead, it will not decay or lose strength while the outer layers are intact. A composite of hollow, needlelike cellulose fibers bound together by a chemical glue called lignin, it is in many ways as strong as steel.

Leaves make food for the tree. Their shapes help them reduce wind resistance, shed rain that could decay the leaf if left standing and produce chlorophyll. The narrow needles of a Douglas fir, for instance, exposes as much as three acres of surface to the sun.

There is a tree to please everyone. Don’t have much space for a fruit tree? Consider a Garden Annie dwarf apricot, a dwarf Garden Prince almond, Compact Stella cherry, dwarf Red Sunset nectarine or a Garden Delicious apple.

Rather not have fruit to contend with? How about a flowering crabapple, cherry or plum? Want a deciduous shade tree that grows fast? Red maples with blazing fall color fit the bill.

Need to screen a neighbor quickly? Then plant a honey locust or catalpa. Another fast growing,deer resistant tree is the silk tree.   It’s flat topped, spreading canopy make this a good patio tree and is especially beautiful when viewed from above, as from a deck or hilltop.  If left unpruned it will become a multi-stemmed tree but with training can be grown as a single trunk 10-20 foot umbrella.   Fluffy pink flowers like pincushions bloom in summer.  Grow it in full sun to partial shade.  With regular water it grows fast.  They are attractive to birds, too. 

Be kind to your trees. They are a valuable asset to your home and our environment.

How to have a Sense of Place in your garden

Leave a comment

Recently I got to enjoy this beautiful October weather walking among the redwoods, mixed oak woodland and open fields watching hawks soar overhead and listening to migrating warblers in the trees.  I was not here in Santa Cruz county, however, but Pt. Reyes National Seashore-a similar but different environment. What struck me was how the gardens of the local residents reflect where they live.  There was a sense of place to the landscaping. 

Our gardens reflect where we live, too.  What can we learn from our surroundings that will help us in our own gardens?

Look to the horizon.  Check views from every possible angel. Borrow scenery if it’s attractive or screen eyesores and distract the eye from them.

Highlight existing features. Develop designs that retain and enhance elements on site like interesting rock formations, meadows, existing trees and native woodland plants.

Consider all aspects of your outdoor space. What are your favorite flower and plant foliage colors?  What patio materials do you like -flagstone, wood, gravel, pavers? What is your favorite season- spring flowering trees and bulbs or fall foliage and berries?  How many hours do you spend enjoying the garden-  sitting, reading, working, relaxing or entertaining?

Whatever landscape design elements you use in your garden, remember they can be broken into smaller parts to make them more manageable- paving this year, planting trees next year, then shrubs, perennials, garden art. Installing a garden is about the journey.  There is never a finishing point.

Important in any design is your choice of trees. More than any other living feature in your landscape, trees contribute to your sense of place. Imaging how different this area would look without the redwoods, spreading oak trees or tall ponderosa pines.

A tree that looks good and thrives in many types of gardens while requiring little summer water once established is the Strawberry tree or arbutus. A relative of the madrone, this evergreen tree is interesting year round. In the fall and winter, clusters of small white or pink, urn-shaped flowers hang from rich, reddish-brown branches with shedding bark. Fruit resembling strawberries ripen in the fall and attract birds. The handsome glossy green leaves emerge from red stems and contrast nicely with the bark, flowers and berriies. Growing to about 25 ft tall they accept full sun or part shade. What’s not to love about a tree with ornamental bark, dainty flowers, decorative edible fruit and handsome foliage?

Another tree to dress your garden for fall is Prairifire flowering crabapple. Birds love the berries and the 1/2 inch fruit remains on the tree for a long time after leaves drop providing food well into winter.  Many of the popular crabapple varieties of the past were highly prone to fungal diseases but this one is among the new disease- resistant varieties now available. Prairifire bloom later than most crabapples with long lasting bright red flowers. Even the red leaves lend color to the garden when they emerge in the spring. If your looking for a small 20 foot ornamental tree with spring flowers and fall berries, this is a good choice for your garden.

Let your landscape express a sense of place to your garden.

Watering, Fertilizing and Weed Control

Leave a comment

Whether you grow a full-blown vegetable garden or a few herbs and edible flowers in containers, celebrate this Fourth of July by serving a menu created with produce harvested from your own garden. It may be too early for your corn or tomatoes to be ready but peas served with a touch of basil would be delicious. A fellow gardener recently told me that she loves steamed baby zucchini cooked with a small pinch of lavender flowers. I haven’t tried this myself but it sounds interesting, maybe garnished some some edible nasturtium or viola flowers.

Actively growing vegetables and flowers need a boost from They use a lot of nutrients, especially nitrogen, at this time of year. Add water soluble fertilizer to your drip irrigation system or apply it through a hose-end sprayer. Sprinkle dry fertilizers over the soil around the plants or apply in trenches next to the rows. Water deeply afterward.

Remember that weeds compete with vegetables and flowers for moisture, nutrients and sunlight. Weeds can also serve as alternate hosts for disease and pest problems. You can prevent weeds from getting out of control by using the "half-hour" rule. Weeding for just half an hour every couple of days will save you hours of hard work in the future. By staying ahead of the weeds, you’ll grow more healthy produce and flowers.

If you battle dandelions and don’t want to use chemical weed killers around pets and children, get out the white vinegar from the cupboard. On a hot sunny day spray straight white vinegar directly on the weed. This method will kill whatever it touches so direct the spray carefully. If the dandelion is in the lawn, wait a week, pour some water on the dead spot to dilute any lasting effects of the vinegar. then pole a bunch a holes and drop in some grass seed. Sprinkle a bit of fertilizer where the seed is planted and keep the area moist. In three weeks you won’t remember where the dead spot was and the dandelion will be long gone.

Trees are the most important living asset on your property. They cool your house and offer shade and protection for your plants. They provide food and shelter for birds and other wildlife. Summer heat can take a toll on trees. Fruit trees, citrus and flowering trees need a deep irrigation every other week. Less thirsty established trees like Chinese pistache and strawberry tree need irrigation about once a month. Newly planted trees need water regularly. Gradually reduce frequency after a year or so.

There are ways to maximize the efficiency of the water you apply.  Drill several 4" wide holes about 24-30" deep around the drip line of the tree, being careful not to damage large roots. Fill the holes with compost and water.   Or you can use a soaker hose on the surface to slowly water the tree.   Mulch heavily all planting beds. Do not use rocks or gravel as a mulch because hey add heat to the soil and moisture evaporates faster.

Happy Fourth of July.
