Watering trees and shrubs during dry weather

During a dry spell, the lawn isn't the only part of the yard that needs attention. Trees and shrubs can become short of water too, especially those planted within the last few years. Their roots are still establishing and may not reach enough moist soil to get through a prolonged dry period.

Check the soil before deciding how much to water. Carefully examine a small area a few inches below the surface, avoiding damage to roots. Soil that feels cool and moist is different from soil that is dry and crumbly. If it is saturated, adding more water can make the situation worse.

Water slowly enough that it soaks into the root area instead of running away across the surface. Then check the soil again to see whether the water has actually reached it. A brief spray over the top may leave the ground underneath dry.

How often you water will depend on the tree, the soil, drainage, recent rain, and the weather. A newly planted tree may need closer attention than an established one, so don't treat a weekly schedule as a rule for every situation.

A suitable organic mulch layer can help slow drying and keep competing weeds down. Keep it away from the trunk, and continue checking moisture beneath it. If a tree remains stressed despite watering, the cause may need a closer look.
