Xeriscaping refers to water wise gardening, hence they require very little water to thrive on. Here are some tips to a water wise garden:
- Use less-than-thirsty plants in your garden.
- Look for plants that are well-suited to regional and local conditions.
- Water plants only when needed, not by the clock or calendar.
- Water at night, when evaporation is much lower and air is calmer.
- A two- to four-inch layer of mulch also evens out temperature extremes, keep soil cool on hot days and warm on cool days.
