What Is a True Mountain Garden?
Those of us who moved to the Sierra Nevada from the cities and suburbs did so because we loved the smell of the cedars, the vertical grandeur of the granite peaks, the lush, green meadows and the ruggedness of the outdoors. We were looking for a more pristine, natural environment than what the urbs and the burbs could provide. Swimming in a mountain lake with a soft breeze wafting over the surface seemed like a baptism in Nature.
Why, then, bring the aesthetic values of the cities and suburbs up here to the mountains? The city garden, for instance, is a study in constriction and confinement. Square patches of overly-watered lawns, manicured and fertilized until they glow like neon in front and back yards, look so jarringly out of place up here, where the lines of the landscape meander and stretch out for miles.
Lawns do almost nothing for the environment, and they use an inordinate amount of water. According to the United States Environmental Protection Agency, "An American family of four can use 400 gallons of water per day, and about 30 percent of that is devoted to outdoor uses. More than half of that outdoor water is used for watering lawns and gardens. Nationwide, landscape irrigation is estimated to account for almost one-third of all residential water use, totaling more than 7 billion gallons per day."
The fertilizers and herbicides needed to preserve a green lawn are washed by rain and irrigation into the very lakes and streams we came up to enjoy in the mountains, making them unfit for swimming and fishing in many cases. Synthetic fertilizers in streams and lakes create algae blooms that block the sun, causing dead zones beneath them. Fish and frogs are especially susceptible to herbicides and can end up producing deformed offspring.
There are environmentally-friendly alternatives to the urban garden. One of these alternatives is a meadow garden. Look at the meadows around us and try to emulate them; plant Sierra wildflowers and meadow grasses that need little watering and no mowing. The result is not only pleasing to the eye, but will save money with lower water bills.
John Greenlee, in his book, "The American Meadow Garden: Creating A Natural Alternative to the Traditional Lawn," writes, "Unlike lawns, meadows are better for the environment, a safe habitat for beneficial insects and pollinators, a place where native ecology can thrive. Meadows, by attracting a diversity of 'life' are animated, alive with rhythmic movement, catching both wind and light." He also suggests that the best place to start a meadow garden is where the lawn is.
Another attractive alternative to the lawn is to introduce more hardscape. Paths, waterfalls, ponds, fountains and rock walls fit into the rocky mountain environment and use little to no water. The sound of water in in the garden is pleasing to the senses, while attracting birds and pollinating insects.
For a green effect, paver stones with moss or other low-growing plants between them produce a country effect and need very little water to maintain. Lemon thyme, for instance, is a good choice as it tolerates freezing in the winter and needs little watering in the summer. As one steps across the stones, brushing against the thyme, a lovely fragrance is released, adding to the overall pleasures of the garden.
Yet another alternative to the urban garden is a rock garden. This is especially effective when dealing with steep hillsides. By piling rocks into attractive, naturalistic shapes on the side of the mountain, you can put planting soil in spaces between the stones and plant a variety of beautiful, drought tolerant flowers and shrubs.
Planting native flowers and grasses will also cut down on watering and will need no fertilizing. A little composted mulch is all that is needed to make a mountain garden thrive in the hot, arid summer climate of the Sierra Nevada. For a list of plants native to the Sierra foothills, go to the Internet site of The California Native Plant Society, www.cnps.org/cnps/nativeplants/gallery/callahan/index.php for suggested natives to plant in this area.
There are few things more spectacular than a mountain meadow with wild flowers and a melange of grasses and shrubs. The fragrance of the vegetation and the view of the surrounding mountains is hard to beat. Why not take it home with us? We can plant our own micro-meadow and enjoy the mountain habitat by just looking out our windows.
