All Plants Have a Place in Water Efficient Landscapes
Texas Cooperative Extension
Revised 6 July 2005 by Dr. Doug Welsh

Every plant in the nursery or garden center truly has a place in a water-efficient landscape. Its not which plant you use, but where you put it. Three different plant zones can be incorporated into a water-efficient landscape:

  • Regular Watering Zone
  • Occasional Watering Zone
  • Natural Rainfall Zone
Plants in the "Regular Watering Zone" would require watering once every week or more ONCE ESTABLISHED, in the absence of rain.

Plants in the "Occasional Watering Zone" would require watering once every two or three weeks ONCE ESTABLISHED, in the absence of rain.

Plants in the "Natural Rainfall Zone" would require only natural rainfall ONCE ESTABLISHED.

By zoning the plants in the landscape according to their water requirements, you prevent the situation of having to overwater one plant type to meet the need of another.

Every region of Texas has a pallet of plants to choose from which are adapted to the soil, temperature extremes and pest problems of the area. The challenge for the professional and
amateur gardener is to categorize the plants based on expected
water requirements. By using the categories of natural rainfall, occasional watering and regular watering, most gardeners can place the plants from their region into these water-use zones.

For example, in much of Texas (areas of 30+ inches of rainfall), the following categorization is often used: Regular Watering Zone: turfgrass and annual flowers
Occasional Watering Zone: perennial flowers and tender woody shrubs and vines
Natural Watering Zone: tough woody shrubs and vines and all trees
All plants do have a place in a water-efficient landscape. Visit your nursery or garden center today and get started on creating your own beautiful, water conserving landscape!
