You will have to check the soil moisture of newly planted trees and shrubs about once a week for the first two growing seasons until the root systems get established. Soil that is moist or damp to the touch is fine. You may need to probe with a screwdriver. If the soil begins to dry out, water the plant deeply. Do this up until the ground freezes. Do not overwater.
Make sure mulch is no thicker than several inches and keep away from the base of the stems. http://extension.umd.edu/hgic/trees-and-shrubs/post-planting-care
