How to Recognize Drought and Water Stress
It's important to be able to recognize the first signs of drought stress because there is a point of "no return" where no amount of water will save a stricken plant. Large trees and shrubs are an investment worth saving. So how to recognize drought stress and how do you save these plants?
- Wilted or drooping leaves that do not return to normal by evening
- Curled or yellow leaves that fold or drop
- Greyish foliage that loses its green luster
- Smaller than normal new leaves
- Lawns that keep footprint more than several minutes
Use whatever water is available to save mature ornamentals and fruit trees. One or two deep, slow irrigations with a garden hose several weeks apart will often keep these plants alive through another dry summer.
