San Antonio summers are hard on trees, and one of the most common mistakes we see is homeowners watering their trees the wrong way. Sprinkler systems aimed at the base of the trunk, or short daily watering cycles, do more harm than good. Trees need water where their roots actually are.
For a mature tree, the active root zone starts at the drip line (roughly the outer edge of the canopy) and extends well beyond it. A slow, deep watering once or twice a week out at that drip line is far more effective than daily shallow watering near the trunk. Think about it this way: you want roots to reach out toward moisture, not stay clustered where the surface dries out fast in South Texas heat.
A newly planted or transplanted tree has different needs. For the first full growing season, it needs consistent moisture closer to the root ball while it establishes. A soaker hose set in a ring about 18 inches from the trunk works well. The goal is to keep the root ball moist, not saturated.
Getting watering right is one of the single biggest factors in whether a tree thrives or declines in the San Antonio climate.
