Does it mean using sand and desert plants?
No, it depends on the climate what you will use to create a water conserving landscape. You are using drought tolerant landscaping. Native plants will be good choices to use, as they have evolved to withstand the varying precipitation cycles of your climate, plus they provide food and cover for wildlife. Suggestions: • Group plants with similar water requirements together. • Pick drought-tolerant species. • If possible channel water to the site, such as the runoff from a rain spout. • Use soak irrigation; use soak hoses instead of sprinklers. • Mulch the site. • Prune when necessary. • Fertilize only when needed. Slow release types are preferred.
