Use turf only in high traffic areas or play areas. Bluegrass typically requires 25 - 30 inches of water per growing season. If you are planning on grass seeding areas of your lawn, group the areas together so efficient watering can take place. By visiting the xeriscape websites listed below or by speaking with nursery personnel, you will get a very clear picture of which plants will work well in your design. There is a place for almost any type of plant as long as they are grouped by their water needs.
Organic mulch does much for a garden area.
Initially they hold in moisture and keep the ground from becoming parched. As they decay they help feed the soil and maintain it's composition. These mulches need to be applied at a depth of 3 - 4 inches and replaced every so often. Inorganic mulch such as gravel and sand can actually create a hotter, drier climate in the garden. Maintenance is required as it is in any landscaped area.
