Watering is critical for newly planted trees, shrubs, and evergreens, especially in the heat of the summer. Water slowly for deeper penetration once per week for the first three weeks. Water once every other week after that until plants are established, in most cases six to eight weeks. If we get one inch of rain in a week, decrease the watering amount. Shrubs and small evergreens need 3 to 5 gallons per plant per watering. Water spreading evergreens in the center of the plant to get water to the roots. Trees and larger evergreens need 10 to 20 gallons per plant per watering. If you questions whether to water, remove a small area of mulch and check soil moisture three or four inches down. If wet, hold off a couple of days; if dry, give the plants a good drink.
Watch for insects and fungal problems. New planted trees and shrubs are particularly susceptible. Fertilizing should be considered only after plants are established, usually after one year.
Winter care is important for the new plants, too. Evergreens need a good watering before the ground freezes in late Fall. Many plants are lost each winter due to rabbits and mice. Certain plants are very susceptible and need protection every winter. Fencing, baits, and repellents can be very effective.
