Answer: New trees should be watered deeply once or twice a week, depending upon weather. The goal is about one inch of water, applied slowly so it has a chance to trickle down and wet the entire rootmass. The easiest way to accomplish this is to dig a water well or water basin directly beneath your trees and shrubs. Once a week flood the basin, allow the water to drain, then flood it a second time. Keep expanding the basin as the tree or shrubs grows so the water you apply goes directly down to the majority of the root mass.
Best wishes with your new trees!
