I purchased 12 lemonthread false cypress but did not get them in the ground . Can they be safely overwintered in their pots? What do I need to do? I’m in Wilmington, DE which is in zone 7. Thank you for any advice.
Find a location out of the wind that blows from the west and north (the east side of a structure or fence is ideal) and sink the pots into the ground up to their rims. If that isn’t possible, set them on the ground out of the wind and pile mulch around them up to the top of the pots. They should be fine if you do this.
