COLUMBIA, Mo. - With drought affecting over 90 percent of Missouri, it's important to remember the well-being of one of the largest plants on your lawn.

University of Missouri Extension specialist Joni Harper says trees are sometimes forgotten about in droughts. Harper says trees are valuable when it comes to home landscapes, providing beauty and offering energy-saving shade.

Signs of stress in trees include wilted foliage, leaf discoloration, and early fall colors. Checking soil moisture with the "screwdriver test" can indicate the need for watering.

In a screwdriver test, you push the screwdriver into the ground. If the ground is dry, you won't be able to. If the ground is wet, you will. If you can't get your screwdriver to easily go at least 6 to 8 inches into the ground, it's time to water.

Mature trees should be watered beneath the entire canopy, while young trees require daily watering during the first week and twice a week thereafter. Proper care also involves mulching to retain soil moisture.
