Where should I water my tree for the best effect?
The roots that absorb water and nutrients are only close to the trunk for about the first 5 years of a tree’s life. After that, these feeder roots are farther out. The optimal place to water older trees is near the drip line, which is the outside edge of the tree canopy where rain would drip down from the leaves. Ideally, you want to water the area half way between the trunk and the drip line, and up to the same distance beyond the drip line. Refer to the diagram. Mature trees do not do well when the trunk gets wet.

Sometimes these areas are covered by our homes, driveways, sidewalks and other impervious areas, in these cases do the best you can. Watering in a lesser optimal location is better than no water.
