In zone 7 - what care is need to prepare this for winter?
Certified GKH Gardening Expert
This plant is not hardy in zone 7. It would need to come indoors to survive the winter. If it is in a container, than it is just a matter of acclimating it to inside your home and you can care for it as a houseplant. It will need the bright light of a South facing window and to be watered only when the soil is dry to the touch. Even with that, it may look a bit ragged over the winter but will perk back up in the spring when you take it back outside.
If it is in the ground, you will need to move it to a container to bring it in. After transferring it to a container, leave it outside to recover for a week or 2 before trying to bring it indoors (As outlined above).
