Answer: I would suggest you use a thick layer of organic mulch in late fall, and make sure they are well watered (if needed to supplement rain) until the ground freezes. The soil should be damp but not sopping wet or saturated both this fall and again next summer while they are new and becoming established. If they are in a windy spot you might want to provide a windbreak for the boxwood this winter. Do not fertilize them until next spring. Good luck wiht your plants.
