Trees and Shrub Water-Saving Methods
All trees and shrubs need more frequent watering from planting time until becoming well rooted, which may take two growing seasons.
Once established, plants can then be weaned to tolerate less frequent watering. Proper weaning develops deep roots and makes the plants more drought enduring.
- As with lawns, water established trees, shrubs and groundcovers infrequently, yet thoroughly.
- In the absence of rain, most trees and shrubs benefit from a once-a-month thorough watering during the growing season.
- Remember, normal lawn watering is not a substitute for thorough tree and shrub watering.
The feeding root system of a tree or shrub is located within the top 12 inches of the soil and at the "dripline" of the plant. The dripline is the area directly below the outermost reaches of the branches.
- Apply water and fertilizer just inside and a little beyond the dripline, not at the trunk. Simply lay a slowly running hose on the ground and move it around the dripline as each area becomes saturated to a depth of 8 to 10 inches. For large trees, this watering technique may take several hours.
