XERISCAPES: WATER SAVING LANDSCAPING

All across America, communities have been faced with increased demands on existing water supplies. In Canada and other countries, we too have faced increased demands on water supplies.

Consequently, there is a greater focus on water conservation, not just in times of drought, but in anticipation of future population growth. 

Water can no longer be considered a limitless resource. 

A philosophy of conservation of water through creative landscaping has created the new term, xeriscape.

The term xeriscape is derived from the Greek word xeros meaning dry, combined with landscaping, thus xeriscaping. The term was coined by the Front Range Xeriscape Task Force of the Denver Water Department in 1981.

The goal of a xeriscape is to create a visually attractive landscape that uses plants selected for their water efficiency. Properly maintained, a xeriscape can easily use less than onehalf the water of a traditional landscape. Once established, a xeriscape should require less maintenance than turf landscape.

The eight fundamentals of waterwise landscaping illustrate the concepts and principles of Xeriscape landscaping and other waterefficient approaches.

- Group plants according to their water needs. Use native and low water use plants.

- Limit turf areas to those needed for practical uses.

- Use efficient irrigation systems.

- Schedule irrigation wisely.

- Make sure soil is healthy.

- Remember to mulch.

- Provide regular maintenance.

Water efficient landscaping offers many economic and environmental benefits, including:

• Lower water bills from reduced use.
• Conservation of natural resources and preservation of habitat for plants and wildlife.
• Decreased energy use because less pumping and treatment of water is required.
• Reduced home or office heating and cooling costs through the careful placement of trees and plants.
• Reduced run off of storm water and irrigation water that carries top soils, fertilizers, and pesticides into lakes, rivers and streams.
• Fewer yard trimmings to be managed or landfilled.
• Reduced landscaping labor and maintenance costs.
• Extended life for water resources infrastructure, thus reduced taxpayer costs.

In short, plan and maintain your landscape with these principles of water efficiency in mind and it will continue to conserve water, as well as be attractive.
