prep potted fern for winter outside?
i just picked up some hanging ferns set out on the curb by a neighbor. they are about half brown, but the green half is healthy and includes strong new growth. i have not had ferns before; afraid i'd kill them
i would like to save them for spring, preferrably not bringing them inside. what's the best way to handle them for a cold winter ? (southern tennessee)
should i set the pots into the ground? clip back the fronds? water or let dry?
i am open to rigging up a small "greenhouse" structure behind the garage, in the sun, if it's possible to use thick clear plastic sheeting effectively. thanks in advance!
