|Hardy hibiscus sometimes die all the way down to ground level in cold winter areas. If this is the case with yours, simply cut them down to ground level in the spring and your plants will develop new stems in late spring or early summer. If yours do not freeze all the way down each winter you can prune them back by one half to two thirds each spring to help keep them under control. The best thing about hardy hibiscus is that they will take any amount of pruning and will still grow and flower each spring.
