Planning Drip Systems for Healthy Trees

Trees can be more complicated than the rest of the plant world. They grow to greater heights and require more water and nutrients than smaller shrubs, bushes, and plants. And, to be healthy, their root systems must grow to greater depths to create long-term stability. Young trees may seem to do well with lawn irrigation and rainfall. However, a supplemental drip system for trees is needed to encourage long-term root growth and depth. Designing a Drip System for Trees Healthy root growth occurs when the soil beneath is moist enough for the roots to grow outward and downward. Improper watering in the early years may cause the roots to grow laterally rather than downward as they seek moisture near the surface. For a new or young tree, the best strategy is to establish a drip system that meters the correct amount of water at ever widening perimeters. Water emitters should be spaced beneath the drip line or outer edges of the tree’s foliage. The placement encourages the ...
