Take advantage of the characteristics of the site, such as sun, shade, wind and soil.
soil bed preparation
Soil is a collection of mineral particles of different sizes. If most of the particles are large (sand), water passes through rapidly. If most of the particles are small (clay), water will penetrate the soil much more slowly. The solution for either problem is the same: add organic matter.
Organic matter, in the form of compost, chopped up leaves or composted manure will improve the texture and water-holding capacity of soil.
Choose plant material that is drought tolerant or native to your area (or a region with a similar climate). These plants will have adapted to your climate and soils.
Mulch allows for moisture to be retained and reduces evaporation. Mulch prevents the soil from being heated up from the mid-day sun -lessening water consumption.
watering & irrigation
Water plants early in the morning. Rainwater is the best choice for plants. Use rain barrels
or a cistern to collect water from your downspouts. Drip irrigation and soaker hoses minimize evaporation loss and keep the areas between plants dry. Soaker hoses ensure that up to 90 percent of the water you apply to your garden is actually available to your plants. Sprinklers are about 40% to 50% effective at getting
moisture to the intended plants.
