400 Anniversary Column Memoirs

Leave a comment

OLYMPUS DIGITAL CAMERAI started writing this column in October 2005. I remember the day the editor of the paper at that time gave me the go ahead and bestowed upon me the title, 'The Mountain Gardener'.  I was so excited. I immediately started writing down every subject I could think of. In the world of horticulture there are myriad subjects to write about and nearly as many different plants. I'll never run of ideas.

This week marks my 400th column. As I've traveled near and far over the years I love to pass on what's growing in that area whether it's in an arboretum, personal garden or the plants native to the region. Last week I took you with me as I traveled to Whidbey and Vashon Islands in the Puget Sound of Washington. The gardens and nurseries were spectacular. There were so many flowers to admire.

I'll never forget another trip I took to Guatemala, Honduras and Utila, an island off the coast of Honduras. It was on Utila that I saw plants growing in washing machine baskets in everyone's yard. I thought it was a clever way to re-use old appliances but wondered why there were so many old washing machines on a tiny island.  A local laughed at me for asking about them and told me the baskets protect their plants from the big blue crabs that come out at night. Seems they'll sever the stems right at ground level and drag the whole plant into their hole. Also the baskets protect the plants from iguanas who will eat anything within two feet of the ground. And you thought deer were a problem.

Redwoods in Maui? I was skeptical too but during a trip to the islands I saw them first hand growing in the fog near Haleakala crater in Polipoli State Park.

Like our area that was clear cut in the 1800's for lumber and to fuel the lime kilns so too the forests of Maui were harvested in the 1700's.  Sandalwood, exported to China for its fragrant aroma, became the island's first cash crop. Millions of trees were logged from the mountain forests. The men of the farming class were forced to cut trees, first on the lower slope and then farther up into the mountains, to pay for the chief's acquisitions of weapons, warships Polish_house_with_sunflowers 2and European imports.  Further damage was done by livestock brought by westerners  – pigs, goats, sheep and especially cattle.  

When the watershed was destroyed, the water disappeared for sugar cane, too. Reforestation started in the 1920's when nearly two million trees were planted annually.  Fast growing species like redwoods, cedar, sugar pines and eucalyptus were planted to increase the watershed.  While these introduced trees and shrubs prevented catastrophic destruction, they produced sparse forests with fewer species than the complex, multi-layered systems created by native forests.

In 2007 the area was devastated by a wildfire. It destroyed most of the forest. The redwood trees survived however. Now the area has been replanted with native trees plus 57,000 redwood seedlings. And that's why there are redwoods growing on Maui.

The gardens in eastern Poland were spectacular. The climate is influenced by the interior of the continent Poland_perennial_bed 2towards Russia and so receives summer rain. The wildflowers, vegetable gardens, perennial and annual flowers love the moisture and were in full bloom. The soil here, deposited by glaciers, is rich with sediment and nutrients. Sunflowers border neat plots of cabbage, beets, potatooes, cucumbers, lettuce and leeks. Black-eyed Susan cover the hillsides with swaths of gold blooms. Besides perennial plants, every garden was chock full of annuals, too. I never saw a nursery even in the outdoor markets so they must start plants from seed.

Polish houses are tidy with nary an abandoned car or farm implement to be seen. Brightly colored ivy geraniums tumble from window boxes. If vegetables or berries such as currants, blueberry, blackberry or raspberry are grown for sale these large plots are fenced with wire. Every 10 feet or so plastic bags are attached and wave in the breeze. I was told this keeps the wild boar, roe and red deer at bay.

I've traveled in southern Mexico twice in years past and enjoyed the Mexican weeping bamboo growing in the forests of Oaxaca. I even bought one to grow in a pot at my own house to remind me of this beautiful area.

On another trip I traveled from Chiapas to the Yucatan and all parts in between. Every area from the tropical lowlands to the mountains grow their own special mix of plants.

In the warmer spots bromeliad, tillandsia, lilies, elephant ears, bougainvillea, coffee, coleus, impatiens and marigolds are typically grown around the house. Scarlet runner beans morning glory, ficus trees, banana, pineapple, avocado, papaya and gum trees are also common. Red clay soil is typical here,  

In the mountains, apples are the mainstay of gardens. Asclepias or butterfly weed grows here although I didn't see any monarchs A village called San Juan Chamula had dozens of greenhouses all growing marigolds.. The Indian people use lots of these flowers as traditional decorations in religious ceremonies. They are also used extensively on the Day of the Dead which follows Halloween. Every small house grows marigolds as well as maize, squash, fava beans and other edible greens.

I haven't touched on plants that I found on trips to British Columbia, Yosemite, Lassen, the Sierra, Big Sur or Death Valley. Guess I'll have to keep writing and visit memory lane another time.

Gardens around The Puget Sound

Leave a comment

My summer travel season started this year in the Puget Sound in the Pacific Northwest. My sister lives on Fox Island overlooking the sound with a breathtaking view of Mt. Rainier. There are so many gardens and nurseries in this area I hardly know where to start when I come up here. Any destination was sure to provide lush landscapes and a cornucopia of colorful flowers.

clematis_tangerine_alstroemeria2green island at the southern end of Puget Sound. After the ferry docked we headed south to visit The Country Store and Gardens. This nursery in the heart of the island boasts mature plantings on a 10 acre site with the nursery featuring rare and and unusual plants along with a wide selection of perennials, shrubs and blueberries.

The flowers of a deep, dark purple clematis mingled with a rich pink, climbing cabbage rose both growing on a long trellis surrounding the front porch of the store. A dead fruit tree was left to provide support for another midnight purple clematis blooming above a bed of deep red Lucifer crocosmia.  I'll remember this exciting pairing for a future design where the spreading crocosmia won't be a problem.

This nursery propagates many of their plants from their own stock. Mature specimens of ornamental grape, lace-cap hydrangeas, tangerine colored alstroemeria, hellebore and heuchera grew in the perennial beds bordered by sections of cut logs. We enjoyed the sweet scent of Summer Ice daphne and admired the velvet red blossoms of Serotina honeysuckle before moving on to our next destination.

swallowtail_on_hydrangea2The Pacific Northwest is famous for their lavender fields. The soil and climate here really agrees with this plant.
Lavender Hill Farm is just one of many lavender growing concerns on the island. On a hill overlooking the picturesque Quartermaster Harbor, several lavender varieties are grown.

You can pick some for yourself or buy some already harvested. Sitting under an apple tree, a young worker introduced herself as Audrey and told me the farm grows several French lavender varieties. Grosso is grown for the long stems and fat flower buds, Provence for intense fragrance and Melissa and Coconut Ice for their pink flower buds. It's a beautiful spot with sailboats docked below in the tiny harbor.

Next stop, famous in the nursery world, was Dig Nursery. I've seen it mentioned in Pacific Horticulture and Sunset Dig_Nursery_waterfeature2magazines. The plants here are displayed in very unique ways making this destination nursery something to be experienced. Massive gabion pillars made of heavy wire fencing and river rocks provide the base for rusted ornamental iron trellises and arbors. More rusted iron is fashioned into hanging planters overflowing with flowers, succulents and grasses.

Repurposed cyclone fence sections provided a perfectly drained platform for more succulents, native plants, herbs and grasses. Several pots of unique black daylilies caught our attention as did the large collection of Darlingtonia and other carnivorous plants. In the shade section, a lime-green lace cap hydrangea was offered for sale with mopheads, Japanese forest grass and hellebore. We wondered if the resting Swallowtail butterfly came with the pot of hydrangeas.

Another ferry another island. This time the ferry takes us to Whidbey Island. Here there are flowers blooming everywhere. Hanging baskets of purple and lilac supertunia, lobelia and red ivy geraniums grace every light pole. The container plantings burst with color. White rugosa roses grow on a split rail fence overlooking the harbor in Langley.

Meerkerk_Gardens2One of our stops on the island is Meerkerk Rhododendron Garden. At this time of year we thought the show would be over but we were pleasantly surprised to find several very specimens still blooming. There are so many kinds of rhododendrons here and we were drawn to one called Golfer with silver fuzzy leaves. Another one had velvety rusty red leaves that sparkled backlit by the late afternoon sun.

The perennial beds were filled with lilac oriental poppy, dahlia, campanula, lavender and shasta daisy. A 30 ft white dogwood shone like a beacon surrounded by the deep green fir trees. Bordering the curving paths, oregano and moss covered fieldstone beckoned one to linger and admire the smaller jewels of the garden.

Another highlight of my tour of gardens was a visit to Chocolate Flower Farm in Langley. If you like deep burgundy, chocolate, black, midnight blue, deep magenta or mahogany flowers and foliage like I do you would  also be amazed by this garden. There is so much to share about this special place that I plant to write about all it's treasures in another column. Stay tuned.

As I left to fly back to California and the redwoods I thought that in some ways this temperate rain forest is not so different from ours. It's a little greener up here during the summer and the daylight from 5am to 10 pm makes the plants bloom like crazy, but there's no place like home.

Good Watering Practices

Leave a comment

philadelphus_Covered_BridgeThe recent heat wave was one for the record books. The temps were not the highest we've ever had around here but as each day melted into the next I kept thinking that fog, nature's air conditioning, was surely on it's way. Even drought tolerant plants need a little help at these times.

Watering is crucial as plants are growing vigorously. Water makes up 90-98% of every plant we grow. It's needed for photosynthesis, as well as reproduction and defense against pests. Checking soil moisture and improving a soils ability to absorb and hold water should be a priority when you're out in the garden. Don't wait for plants to wilt and burn before correcting watering problems.  

There are ways to water more efficiently and ways to conserve that water. Now is the a good time to review some good watering practices and guidelines.

When is the best time to water? Watering in the morning is the most efficient whether you water by sprinkler, drip system, soaker hose or by hand. The water soaks deep in the soil without risk of evaporation. It bolsters the plant for the day and has dried from leaves by evening reducing the risk for foliar diseases like mildew. Plant roots are also more receptive to watering in the morning.

Is it true that water droplets will scorch leaves in the sun? According to a study published in New Phytologist, a journal of research in plant science, there is a slight risk of leaf burn on fuzzy leaved plants in the sun. The hairs can hold the water droplets above the leaf surface and act as a magnifying glass to the light beaming through them. The study also reported that water droplets on smooth leaves, such as maples, cannot cause leaf burn, regardless of the time of day.

I my forty years of gardening, my own observation is that the leaf burn on a fuzzy leaf must be very small, indeed, as I've never observed any damage. If you find a plant needs water midday, by all means go ahead and water it. Containers even benefit from the cooling effect that watering provides

Most plants need 18" depth of well-drained soil to thrive although trees and many vegetables roots grow several feet deep. More than an inch of water per week may be needed for their success and in the case of many trees and native plants, deeper but more infrequent watering is required.

You can easily measure how much water you are applying. If you have a sprinkler system, place a straight-sided container like a tuna can on the outside edge of the area being watered. Let the sprinkler run until one inch of water has accumulated in the can. When using a drip system or soaker hose, irrigate until a 3" deep test hole dug 1 ft out from the emitter or end of the soaker is moist. Moisture at that level indicates than an inch of water has been applied. The best way to determine how many inches of water your soil needs for a good soak is by digging down after the water has had a chance to settle. When watered well, the soil should feel cool and damp at the bottom of the hole. If the soil feels warm and dry you haven't watered long enough. You need to do this test just once to get a feeling for how much water your soil can hold and how deeply it's soaking in.

if you have a lawn, decide if you really need it that large and maybe not in the front yard at all.  Keep the mowing height high during the heat of summer.  Mow when the grass is about a third taller than recommended height. For common fescue, mow when the grass is 3-4" tall, with your mower set at 2-3 ".  Fertilize only when your lawn needs it to keep a good green color.  Over fertilizing results in quick top growth which needs more water and is susceptible to insect damage and fungus problems.  A good rule of thumb for watering a lawn is to water 1 x per week when the temperature is 70 – 80 degrees., 2 x per week when it's 80 – 90 and 3 x per week only when it's above 90 degrees.  Make sure the water soaks in encouraging the roots to extend  30" below the surface which will make your lawn more drought tolerant.
 
Consider replacing your lawn with a walk-on ground cover like woolly thyme or chamomile.  You can't play touch football on these ground covers but they will tolerate light foot traffic.  Another alternative is to plant low growing native grasses that require only a handfull of trims per year compared to a conventional lawn.
 
Water wisely in other areas of your garden.,  Construct soil basins and furrows to direct water to plant roots and increase this basin as the plant grows or use a soaker hose on the surface to slowly water at the drip line of trees and shrubs. 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.

And above all, mulch, mulch, mulch.  Cover the soil with at least 2" of organic mulch such as compost or chipped bark.  The mulch holds in moisture as well as keeping roots cool and gradually decomposes and enriches your soil.  Keep it away from the base of trunks or plant stems. Don't use rocks or gravel as a mulch because they add heat to the soil and moisture evaporates faster.

Take good care of your plants this summer.
