Q.What Do I Do When My Chokeberries Arrive?
I ordered some 2-3 year old chokeberry bushes, only now I see that they ship in november. I live in northern Maine, and the ground may be frozen by then. Should I container them over winter? How would I go about making sure they survive?

Yes, you will want to leave them in container. Though they are VERY cold hardy, they will appreciate an early spring planting. If you don't have a horticultural lamp, you can keep them alive (but likely not the happiest) indoors using natural window light, given you can find a well lit spot.
