Should I prune a hibiscus that has wintered indoors?
I have 2 (two) hibiscuses, one is a shrub, the other a topiary. Both are being kept in my garage to weather out the winter in coastal NC; I use a small heater to keep the temperatures above 50 F. They are both at an eastern facing window. Both still have their leaves, and are watered once a week. Should they be pruned before they go back outdoors when they can tolerate cool overnight temps? (I already receive your weekly newsletter by email).

Yes, you can prune those in spring before they go out. I believe these are tropical. If not, you can plant hardy hibiscus outside.
