Answer: One of the advantages of container-grown trees and shrubs is that they can be planted any time the ground isn't frozen. In general, they winter over better with their roots under ground and insulated than they do above ground in pots. Be careful to water them in well at planting and mulch them. Make sure the soil stays moist (you may not need to water while the weather is cold, but check to be sure as the weather warms) and then in spring and summer make sure they receive adequate water just as with any newly planted trees. If your location is windy, it may also help to wrap them in burlap for this first winter to protect them from drying winds.
