NOTICE: many of our plants and trees are shipped in a dormant condition. If you receive in dormant state soak overnight before planting. In general, these items can be planted anytime your ground is not frozen. An early snow or frost will not harm a nursery stock item that is already dormant. On the other hand, these items can also be planted during warm weather--simply be sure to water well.
