Saving Water in the Garden

With so much rain this winter it's easy to forget just how precious water is. Globally, water is the new oil. In our own Santa Margarita aquifer everything we can do to replenish the groundwater is vital for our own survival and for that of generations to come. Water cost money – to buy, store, collect, pump, filter and distribute. It just makes good sense to be water wise in your home and garden.

Scotts Valley Water District has been offering a free information series during January about water conservation. Each Wednesday night from 7:00-8:30 a different subject is presented. They are open to the public. I've attended two so far- Storm Water Management and Rainwater & Greywater Harvesting, lots valuable information about ways to save water and money.

When it rains it pours. Think about ways to slow this free water from the sky and prevent it from running off your property. Allow it to spread and sink into the ground. Easy ways to do this can also make for a beautiful landscape.

Design your patio using permeable pavers that allow storm water to percolate into the soil. Whether you choose flagstone over a gravel base, pervious concrete, interlocking pavers with spaces between or crushed gravel all enable rainwater to seep into the soil, recharge the aquifer and prevent runoff into streams and storm drains.

Pervious pavement for driveways can capture runoff , recharge the groundwater and keep pollutants in place in the soil. Large volumes of runoff causes serious erosion and siltation in rivers and streams. Naturally occurring micro-organisms digest car oils, leaving little but carbon dioxide and water. Turf block (concrete blocks with holes) is a good choice for areas that don't receive a lot of heavy traffic and can also be used for paths with gravel or groundcover between.

Plants and trees also slow water runoff. They help stabilize slopes and prevent erosion of valuable nutrient-rich topsoil. They create wildlife habitat and act as a natural pest control. A beautifully designed landscape using California native or drought tolerant plants reduces the need for fertilizers, pesticides, excessive watering and overall maintenance requirements.

You can design a rain garden to capture stormwater runoff from roofs, driveways and other impervious surfaces and allow the water to sink back into the ground. A dry creek bed can also be a good way to slow runoff. Some utilize drain pipe underneath to capture the rainwater so it has time to percolate into the ground.

Using vegetation or mulches to cover bare soil is a key ingredient to slow down runoff. Mulches are a good choice for areas with less than 33% slope, Vegetation works well on areas with less than a 50% slope. Mulch can be organic-such bark chips, straw or grass clippings or inorganic gravel or cobbles. All protect soil from erosion, conserve soil moisture and prevent weed growth. It's all part of the plan to slow, spread and sink water back into the ground.

Installing a rain barrel is a simple way to catch rainwater runoff from your roof. If you have room you might consider a large water tank above or below the ground to collect water. A friend of mine operates a small nursery on her Watsonville property. Sherry and her husband, John, decided to collect the rainwater runoff into a series of tanks to save money and utilize this resource. The 4500 sq.ft roof of their barn provides enough water to fill 3 large tanks. Last year they collected enough water to irrigate their nursery, Terra Sole, for quite a bit of the year. They eventually plan to install solar panels to offset the energy required to pump the water. Every little bit helps

If you'd like more information and ideas about how to beautify your landscape and save water, maintenance costs and time  please come to the last Water Wednesday presentation by Scotts Valley Water District on Jan 30th at 7:00 pm at their office on Civic Center Drive. LeAnne, the water conservation coordinator, and I will be showing slides of landscapes, some of which I designed, that feature low water use plants, lawn replacement ideas and California natives. There's a solution for every family and lifestyle.
 

Vertical Green Walls in Tacoma & Seattle

Winter is a great time to daydream about future gardens – the garden that could be, the garden of your dreams. Soon it'll be time to prune the roses. The fruit trees are there just waiting for dormant spray and a little winter pruning and those tangled vines beckon you every time you walk by. But for now why not let your imagination go wild and consider adding a green wall to enjoy while you sit on the patio this summer?

While I was up in the Pacific Northwest over Christmas time I had the opportunity to visit two impressive green walls.  Also called living walls they got me thinking about the wall behind the patio table on my deck. It would look just awesome covered with living plants. Much of the cost of a large green wall installation is the irrigation system which allows for easy maintenance but since I'm willing to water it by hand every few days my wall will be an affordable version. First though, some inspiration.

The first wall I visited was the 20-by-40-foot living wall at the Goodwill-Milgard Work Opportunity Center in Tacoma. Designed by the the famous French inventor of modern green walls, Patrick Blanc, this wall literally dripped with plants, moss and raindrops on the day I was there.

Installed in 2009 the diagonal swaths of plants are inserted between a double layer of felt, slit to make planting pockets. Most of the soil was knocked off small 4" plants, even the woody plants. I read that Blanc used 96 different species initially but only the toughest have survived. Granted it was December when I saw the wall and some of the plants were dormant but those remaining were quite colorful and made a beautiful tapestry. Stripes of golden acorus grew beside ribbons of bergenia, artemisia, euphorbia, rubus, carex grass, Asiatic jasmine, thyme, pachysandra and vinca minor. Bands of variegated iris high up on the wall caught my eye and I marveled at the woody lily-of-the-valley shrubs and skimmia that remained small in this environment.

A drip irrigation runs across the top of the wall and in a horizontal band halfway down. Water and fertilizer drip through the felt to keep the plants perpetually moist and nourished similar to the mossy cliffs where many of these plants grow in their native environments. There's a freeze switch to stop the irrigation on the coldest days so the wall doesn't turn into a solid wall of ice.  I was told that the wall is pruned twice a year via a cherry picker.

The plan for my own living wall is to mimic the look with those Woolly Pocket planters made from recycled plastic bottles. They're the simplest and lightest to use. For clients I can suggest an outdoor wall near the kitchen planted with rosemary, oregano, thyme, parsley and other sun-loving herbs. Or in a super shady spot, the pockets could be planted with hardy houseplants like spider plant, creeping jenny, queen's tears, small ferns, wandering jew and creeping charlie. These have all survive at my house under the overhang for more years than I can count.

The second living wall I visited in Seattle covered a new building outside the new Amazon offices. This green wall is constructed from a vertical metal grid that supports square modular trays. The plants grow lush in soil pockets with micro spray irrigation providing moisture and nutrients. The effect is beautiful to look at and experience.

Winter chill made the plants pop with bright colors and glowed with deep gold, burgundy red, acid green and tawny auburn. Diagonal bands of familiar hardy plants such as carex buchanii, cotoneaster lowfast, iberis, star jasmine, Powis Castle artemisia, liriope and ferns drew my eye up, down and sideways. The wall encloses a small plaza with warm wood and concrete seating which would be inviting to sit and stay awhile on a warm day.

I'm looking forward to putting together my own green wall. I may even grow succulents in a frame in another spot.  It's an easy fun project to enhance your time outdoors and I plan to suggest this design solution whenever possible in the future.  Take the time to day dream about something new and fun for your own garden.

Native Plants for Winter Birds in the Santa Cruz Mts.

There's no way around it. January may signal the start of the new year but most of our plants still have the day off. I need inspiration on these cold mornings when most of my plants are asleep. This is the time of year when it's doubly important to include plants in your garden that can take a licking, keep on ticking and provide some much needed food for our feathered friends.

During the winter small songbirds and hummingbirds face big challenges, too. Just like us, they need to keep warm.  Our fuel might be a comfort food like hot stew, theirs are foods rich in antioxidants and fats or high octane nectar. Native shrubs with berries or nectar at this time of year will benefit them as well as providing hardy winter color in your garden.

Small flocks of Chestnut-backed chickadees frequent my garden regularly. I can hear their familiar chattering from quite a distance. I read in Audubon magazine that they weigh about as much as a dozen paperclips but their bodies are large for their mass. They have to ramp up the number of hours they devote to feeding. At night chickadees cram themselves into tiny cavities and shiver, burning the day's fuel to keep from freezing.

Other birds that I enjoy in my garden at this time of year are Lesser goldfinches, Townsend warblers, Ruby-Crowned kinglets, robins, brown creepers, Hutton's vireo, Dark-eyed juncos and Anna's hummingbirds.  These native plants will make both of you happy and it's not too late to plant.

Mahonia (Berberis aquifolium) is one of my favorites for winter color and spring berries. Fat cluster of golden yellow flowers light up the Douglas fir woodland understory. In the garden it has a surprising level of adaptability to tough conditions including low water, not-so-great soil and shade or partial sun. In the barberry family, they have gorgeous prickly foliage and powdery-blue, then black berries that the birds devour in late winter and early spring. Hummingbirds rely on the flowers as a source of nectar-rich food in wintertime when there isn't much else around. I saw them visiting these beautiful flower spikes in Seattle recently at Chihuly Glass Exhibit (got the spelling right this time). There are many cultivars of mahonia now available and they are all great.

Common Snowberry (Symphoricarpus albus) is a native that starts its show in fall. It thrives in a woodland garden or in the dry shade under oak trees. A background plant most of the year, the white berries on thie 4-foot shrub stand out when the leaves drop.  Seldom troubled by pests this small shrub can be used to control erosion and is deer resistant. Beautiful ornamental white fruits cover the plant at this time of year and are valued by varied thrush, robins and quail.

Hairy honeysuckle (Lonicera hispidula) can  provide both berries and nectar for local birds. Large, pink nectar-rich blossoms give way to red juicy berries in the fall and often hang on the vines during the winter. They are relished by birds. By pruning them a bit to get more branching they'll be denser and flower more. It's as deer proof as they come. They do well in clay soil in full sun and also shade. Snowberry, Hummingbird sage, toyon and coffeeberry are other natives that complement them.

Toyon (Heteromeles arbutifolia) is the official shrub of the State of California. Also called the Christmas berry shrub it's common in chaparral and open wooded forest. Many birds enjoy their bright red berries throughout the winter including cedar waxwing, bushtit, warblers, robins, flickers, finches and sparrows.  Toyon make a good screen as well as a beautiful specimen plant. They are drought tolerant when established but tolerate some water in the garden if drainage is good. They are relatively fire resistant, like full sun but will tolerate shade. They adapt to sand, clay or serpentine soils. Butterflies also are attracted to the flowers in the summer.

These are just a few great natives to plant in your garden. Other native plants for the winter garden are Pacific wax myrtle, Strawberry tree and Red-twig dogwood.  

By choosing plants that are native to our region birds spend less energy and time foraging for food as they more easily recognize them as a food source. You can have your beautiful berries and color and the birds can eat them, too.
 

Chihuly Garden & Glass

Recently I visited a garden of glass and it was spectacular. At the base of the Space Needle in Seattle, the newly opened Chihuly Garden and Glass Exhibit is a marriage of garden and art like no other I've ever seen. To experience larger-than-life blown glass in vibrant rainbow colors nestled among trees and shrubs was magical. I was transported beyond the ordinary to the extraordinary.

You may have seen some Dale Chihuly glass art at the DeYoung Museum when it was displayed there several years ago. Some of the pieces were influenced by Pacific Northwest American Indian art, others reminiscent of plants and sea forms. In a PBS special currently airing called Chihuly Outside, I learned that his love of blown glass has evolved since 1995 from installations in glass houses in Europe and the U.S. to massive outside exhibits in Finland, Venice, Japan, Australia and Jerusalem. The Chihuly Gardens and Glass Exhibit in Seattle is his most ambitious project ever.

Soft winter sunlight backlit the glass art that seemed to sprout up from the earth. Evergreen magnolia trees, pines and weeping cedar formed a dark green backdrop for the vivid blue, red, yellow, orange, mauve and chartreuse blown glass. Coral Bark maples echoed the same shade of glass reeds and spears. Red Twig dogwood sported a stand of fiori or flower inspired glass. Cobalt glass spheres reflected the Space Needle nearby. Swaths of steel blue eryngium or sea holly were still blooming a bit complementing the ruby glass behind.

Seattle is cold in the winter with lots of rain (sound familiar?) so plants appropriate to the site and climate are a must. Lily-of-the-Valley shrubs provide year-round interest. Their burgundy flower buds hung in clusters ready to open in the spring. Mahonia, which are native to our area also, bloomed with spikes of yellow flowers attracting hummingbirds that over winter in the area. Helleborus or Lenten Rose held tight flower buds just waiting to open. Sasanqua camellias in pink, rose and white popped with color.

Lots of burgundy coral bells carpeted the ground in front of massive logs that looked like petrified wood. I had to check for myself. Mondo grass, epimedium, strawberry  begonia and Japanese Forest grass complemented more flower inspired glass art. Strolling the garden and looking at the glass from different angles as the changing light filtered through was awesome. Chihuly doesn't so much mimic nature as borrow inspiration from it. As with all art, it's in the eye of the beholder and I fell, hook, line and sinker under its spell.

This garden of glass reminds you of frog legs with webbed toes, anemones waving in the incoming tide, towers of tall ti plants. Harmonizing plants and art is the creation of designer Richard Hartlage. Conifers, evergreen grasses, small shrubs and ferns set off the brilliant glass art. A green roof can be seen from above,a green screen of evergreen clematis encloses one side and large crape myrtles provide beautiful winter bark that blends with the lavender and burgundy glass sculptures.

A visit to the Chihuly Garden and Glass exhibit in Seattle was a day spent with light and glass and the plants that make them sparkle. I hoping to see this garden next July when the asters and rhododendrons are in bloom. Even in the quiet months of winter it was spectacular.
 

Happy New Year 2013 from The Mountain Gardener

It's a humbling experience to read some of my past columns celebrating the New Year. Once you write something down it's there forever. Like a social media post it can haunt you. Such lofty goals I've set for myself over the years. But now it's that time of year when I look around the garden and think about the good things I accomplished and some that didn't get done.  A garden reflects our lives- always room for growth as well as reflection.

We live in a rain forest. Easy to remember the past few weeks as gentle and not so gentle raindrops fall on the thick redwood duff beneath the trees.  Mushrooms of every color and type poke through leaves still bright with the shades of fall. Last year was pretty dry until March. Not that great for fungi but this year should be spectacular. All the better to continue learning about our local mushrooms. It's one of my favorite goals for the New Year. The fungus fair in Santa Cruz is coming up the weekend of January 11th and I want to be better informed before my volunteer shift as a basketeer arrives.

Each year I pledge to plant more things to eat. Edibles in the garden feed both the body and the soul. They are more than just vegetables and fruit trees. When you grow something you are being a good steward of the land as you enrich the topsoil using sustainable organic techniques. You can connect with neighbors by trading your extra pumpkins for their persimmons. Knowledge of how and what to grow can be exchanged, seeds swapped.
Growing edibles is more that time spent doing healthy physical work it's connecting us to the earth and to each other.

This year I was able to visit gardens in far away places such as Poland to learn about Eastern European landscaping styles and traditions. Some were very different than what we are used to here in western gardens. Gardeners, though, are the same everywhere-eager to show off and share. I also had the opportunity to visit Abkhazi Garden and the famous Butchart Garden in Victoria, British Columbia during the summer. Nothing can prepare you for the wonder that can be created out of nothing. I came back overflowing with inspiration for my landscape designs.

Next I plan to visit Chihuly Gardens in Seattle and a green wall installation in Tacoma. There's no better way to recharge your creative batteries than to see an inspiring garden. Even a walk around your neighborhood can give you ideas for your own garden. I can't tell you how many times I've seen a huge boulder and wished I could magically transport it to my own yard.

New Years resolutions for gardeners should be mere suggestions. Don't get hung up on achieving everything you would like. Your wish list will serve you well during the cold, wet days of winter even if you don't get them implemented. Sure planning a landscape that conserves water will benefit the environment and your budget. And ordering seeds for the spring garden is great therapy for winter blues and future meals. But there's always next year or next month or the summer after next.

Dreaming is more than an idle pursuit. It's good for you and improves the quality of your life over the long haul. So don't worry if you don't get to everything you hoped to accomplish. It's all in the baby steps. We gardeners are eternal optimists. Why else would be plant a tree or a seed or a garden?

Happy New Year from The Mountain Gardener.

Winter Solstice Christmas Traditions

We all celebrate the holidays in different ways. Each family has their own traditions and warm memories from years gone by. Some of us celebrate Christmas, some Hanukkah, some Kwanzaa. Many of our traditional Christmas customs originate from Winter Solstice celebrations. The plants associated with each are an important part of their tradition and symbolism.

Winter solstice is the 21st of December. Solstice literally means "Sun Stands Still' and for a few days around this time of year the sun appears to stand still in the sky. Nearly all cultures and faiths have some sort of winter solstice celebration. They have been with us for thousands of years starting at the beginning of agriculture among people who depended on the return of the sun. We have incorporated many of the plants from traditional winter solstice celebrations into our own- holly, ivy, evergreens, rosemary, mistletoe and poinsettia. How did this come about?

Holly remains green throughout the year when deciduous trees like the oak shed their leaves. Decorating with it throughout the home has long been believed to bring protection and good luck. Placing a ring of holly on doors originated in Ireland since holly was one of the main plants that was green and beautiful with its red berries at this time of year. Norseman and Celts use to plant a holly tree near their homes to ward off lightning strikes. The crooked lines of holly leaves gave rise to its association with lightning and in fact holly does conduct lighting into the ground better than most trees.

Like other evergreens, ivy symbolizes immortality and eternal life. In England it is traditionally used in kissing balls with holly and mistletoe. It has also stood for fidelity, healing and marriage. Ancient Romans thought it brought good luck and joy. It was worn as a crown or fashioned into wreaths or garland.

Evergreen trees play a role in solstice celebrations. Early Romans and Christians considered the evergreen a symbol of the continuity of life. Fir, cedar, pine boughs and wreaths were used to decorate homes. Small gifts were hung from the branches in groves. This may have been where the Christian tradition of decorating an evergreen tree  or Yule tree, in December originated. Other sacred trees of the solstice are yew, birch, arborvitae and ash.

We often see rosemary plants trained into a Christmas tree shape. Rosemary is evergreen in the winter and blooms at the same time making it the perfect plant for the holidays. Traditionally rosemary was spread on floors at Christmas as people walked over the herb releasing the fragrant scent and filling the home with blessings and protection.

How did our enduring fascination with mistletoe get started? From earliest times it has been one of the most magical, mysterious and sacred plants of Greeks, Celts, Scandinavia, England and European folklore in general.The Druids believed the mistletoe's magical powers extended beyond fertility. It was believed to cure almost any disease and was know as the "all healer". Sprigs fixed above doorways of homes were said to keep away lightning and other types of evil. Because the plant has no roots it was believed that it grew from heaven.

Kissing under the mistletoe probably came from the Greek/Roman belief that it bestowed fertility and had life-giving power. In Scandinavia it was considered a plant of peace under which enemies could declare a truce or fighting spouses could kiss and make up. However this tradition originated it's a good one.

The Yule log dates back to the Saxons and Celtics. Oak trees represented strength, endurance, protection and good luck. It was the most sacred tree of Europe. On the eve of the winter solstice, the longest night of the year, people would keep a huge oak log burning for 12 hours. They would toss oak twigs and acorns into the fire, shout out their hopes and resolutions for the coming New Year and sing Yuletide carols. A piece of the Yule log was saved to start the fire the following year.

It's traditional for us to have some poinsettias in the house for the holidays but they don't have a very long history of European tradition like other plants because pointsettia is a native of Mexico. In the 1820's President Andrew Jackson appointed Joel Roberts Poinsett as the first U.S. Ambassador to Mexico. In 1828 he found a beautiful shrub with large red "flowers" growing next to a road. He took cuttings and brought them back to his greenhouse in South Carolina. Because the leaves turn bright red around Christmas time they have been used as decorations for the holidays ever since.
 
Traditional plants symbolic of Hanukkah are the citron, myrtle twigs, willow twigs and palm fronds. The Four Species are weaved together along with special blessings as part of the synagogue service or at home.
Kwanzaa, another celebration of light, features the harvest foods of Africa: ears of corn, fruit and nuts. It is a secular celebration observed during the last week of December to celebrate the "fruit" or accomplishments coming out of the year of labor.

Around the world, holiday celebrations have their own special meaning. With friends and family, embrace your traditions and have a wondrous holiday.
