Guest post by Eric Berry of The Care of Trees

It's easy to forget that trees need watering during dry spells, just like other plants. It is better to water deeply or soak the soil than to water more frequently with less water.

Watch the weather forecast. If rainfall is plentiful, extra water may not be needed. Use a rain gauge or simply place a cup or can in your garden to monitor rainfall and/or your sprinklers. Don't overwater. Too much water, especially in poorly drained areas, may do more harm than good. The best way to water is to place an oscillating sprinkler next to the trunk and water in an arc directed away from the trunk. Mulching and watering should be part of a comprehensive tree care program.



What can I do now to make sure my trees are healthy throughout the summer?

Check your trees for damage that may have occurred due to recent storms.
Check mulch rings to see if additional material needs to be added. If the mulch is less than 2 inches thick, grass growing through it may become troublesome. Enlarge mulch rings whenever possible.
Monitor for insects and diseases. Check your trees and shrubs regularly for any sign of pest activity.
Avoid using herbicides beneath trees that warn against such use on the label. The same herbicides that kill dandelions can hurt trees if they are not applied properly.
