Xeriscaping is a landscape method that reduces or eliminates the need for supplemental water from irrigation. It is particularly effective in regions prone to drought or where water conservation is a priority. It should be common practice in all landscape design as the pressures of using the planet’s resources increase significantly over the next decade and into the future.
The term xeriscaping comes from the Greek word “xeros,” meaning dry, and it involves the use of drought-resistant plants, efficient irrigation techniques, and other water-saving practices.
There are some basic design principles involved when considering xeriscaping. Consider the local climate, soil type and available water resources for the space you are creating.
Simple Xeriscaping Design Principles
Soil Type
Soil type makes a significant difference not only to the plant species you are designing for, but also the drainage properties of the space you are creating. Reactive soils hold the water for longer periods and particular species do no tolerate having their roots waterlogged. Not only this, reactive soils can create issues with the footings of any buildings particularly when there are trees in the vicinity.
The soil should be improved. Enhancing soil quality will enhance plant health which reduces the consumption of water if species are well chosen and compliment the soil type.
Irrigation
Implementing systems like drip irrigation or soaker hoses minimize water wastage. Often sprayers will spray water onto concrete areas if not adjusted or designed correctly. However, sub-surface irrigation systems can be a maintenance problem and get damaged easily.
Species Selection, Drought Tolerance, Hardiness and Availability
Choosing native or drought-tolerant plants that require less water and are adapted to the local climate is essential. The same goes for applying mulch to retain soil moisture, reduce evaporation, and suppress weeds. Recycled mulch is a great idea if felled trees can be reused onsite.
Reduction in Turf Spaces
Limiting the use of high-water-demand turf grass and replacing it with spreading native ground covers is another design principle that should be used.
