October is a good time to plant trees and shrubs, since dormant plants will be under less stress. Newly installed deciduous plants require almost no watering during the winter months, but don’t forget that a thorough initial watering is paramount. Monitor evergreens, such as junipers, hollies and aborvitae, for watering needs if rain is sparse. Even in winter a plant with leaves on it will transpire. Winter wind desiccation can hurt an evergreen tree that lacks sufficient moisture.
