When planning an irrigation system for trees, a common misconception is that tree roots will "grow toward water." Roots will not grow through dry soil.
Trees require water in a larger area to allow the roots to spread out and provide a sturdy base for the tree.
Young trees need enough drip emitters to cover the canopy from the tree trunk out to the ends of the branches.
Mature trees should have enough drip emitters surrounding it that 50 to 75 percent of the tree's canopy area should be wet.
If a tree is standing alone in a landscape, its demand for water increases as the tree and the roots grow. The wetting pattern must be increased at the same time. Roots only grow in soil that provides moisture and growth can be stunted if the roots can't find moisture as it tries to grow.
