Here’s how to grow drought tolerant plants for xeriscape gardens that save water.
Xeriscaping, commonly known as drought-tolerant gardening, can be spectacular water-saving gardens when planned properly and maintained regularly.
In a nutshell, xeriscaping is landscaping using plants that do not require additional watering above normal rainfall. These gardens are typically advocated in areas prone to drought, such as Arizona. A xeriscape garden is also perfect where the pace of development is outstripping water reserves, such as Los Angeles. Xeriscaping provides a great way to have a great-looking garden without overtaxing the water supply.
Drought Tolerant Plants Save Time and Water
Xeriscaping and desert gardens require a design that minimizes rainwater runoff and evaporation. Fortunately, an interesting selection of flowers, grasses, cacti, shrubs, and trees can do very well in low-water environments. This plant variety provides many exciting design opportunities for a desert garden. Plant varieties commonly used in xeriscape gardens include cacti, agave, lavender, juniper, thyme, and various kinds of sedums. Many semi-tropical plants can survive in protected desert areas as well.
Fewer than 10 inches of rainfall falls annually in most desert areas, making growing plants a serious challenge. In addition, many dry areas also suffer from hard clay-type soils such as adobe. That makes getting water down to deep plant roots especially difficult.
Plant Xeriscape Gardens for Longer Growing Season
On the other hand, xeriscape gardens have distinct advantages as well. For one thing, they enjoy longer growing seasons than gardens in colder climates. In some cases, desert gardens allow avid gardeners to practice their horticultural skills every month of the year. By definition, water bills are lower with xeriscape gardens, making more water available for other uses and needs.
Because of reduced water availability, xeric gardens sprout fewer weeds that need to be pulled. Because xeriscape yards rarely include turfgrass, lawn-mowing chores are reduced or eliminated.
Xeriscape Design Is Clean and Minimalist
In communities that periodically restrict water usage, drought tolerant plants look better and live longer than their water-thirsty peers.
To design a workable and attractive desert or xeriscape garden, try the following:
- Design beds to maximize water retention and minimize water runoff. If gardening in a hilly or sloped area, plant the most water-needy plants at the bottom of the slope. Create a tiled or paved channel so that more rainwater will reach them.
- Chose flowering plants that bloom at different times to keep as much color as possible in your garden. Don’t expect perennials to bloom continuously.
- Remember, there is beauty in all living things. Learn to love the minimalist look of fewer plants and little or no grassy lawn areas.
Maintaining a Xeriscape Desert Garden
A xeriscape garden filled with drought tolerant plants requires far less maintenance than a traditional lawn-dominated yard. But that’s not to say there is no maintenance involved. One tool that is very useful in keeping a xeriscape yard looking tidy is a cordless electric blower.
A cordless electric blower can be used to blow leaves and debris from gravel mulch and other areas between plants. Plus, it is far quieter than a gas-powered model. Read the HG&H story about the Best Cordless Electric Leaf Blowers.
Drought Tolerant Plants for Xeriscape Gardens
When choosing drought tolerant plants for your xeriscape garden, remember to group plants with similar water needs together. For example, cacti and other desert plants should be grouped together. Also, select flowering perennials that bloom at different times during the growing season.
Below are some of the best drought tolerant plants for xeriscape gardens.
