Xeriscape Landscape Design & Planning

Author Teresa Odle

If you’re planning a xeric garden for spring, and especially if you’re planning to take out a grass lawn and replace it with gravel and xeric plants, try planning your garden in recommended water zones.

Ripping out grass and replacing it all with gravel represents many homeowners’ idea of xeric gardening. They soon find out that it’s not the best solution when a tree left in the middle of a gravel lawn dies and their home cooling bill skyrockets.

So let’s consider zones instead.

Arid Zone

You’ll want your most arid zone farthest from your house. Choose native plants that need the least amount of water, hopefully no supplemental watering at all. That might include cacti, yuccas and many varieties of native flowering plants like Kniphofia uvaria (Red hot poker) or Berlandiera lyrata (Chocolate flower). It all depends on your landscape and personal preference.

Transition or Middle Zone

Your next zone can blend some lush, medium water areas with drier ones. Here’ you’ll use plants that take low and medium water. They only need water beyond nature’s supply about once a week or less. It’s a great spot for medium-water shrubs and trees, such as Spartium Junceum (Spanish broom) and various native oaks to provide summer shade, but let winter sun shine through.

Mini-oasis Zone

If you want to keep some grass, here’s your chance. Drought-tolerant grasses like Bermuda, Blue Grama, or Buffalo Grass need little watering but keep your lawn green and other plant roots cool. When used in moderation, and not to cover huge areas, they are still low to medium water choices for this zone. Add some annual flowers in beds or containers up close to the house. By placing lusher plants and turf that need a little more water closer to your home, you help cool your house and take advantage of water runoff from the roof and downspouts.

Of course, the drawing simplifies the concept. Landscapers who understand xeriscaping concepts know how to make your zones appealing and customized for your tastes and gardening ability. And by using microclimates, mulching, welling and other waterwise concepts we’ve discussed in other posts, you can push the limits in some of the zones. The basic concepts are to keep from overusing water and avoiding undermining the health of existing trees, along with the comfort and appearance of your home.
