I think I may have overpruned my hibiscus, because there has hardly been any new growth since I pruned it. It is now the third week of March, and I pruned it the third week of January. I left some leaves, though not too many, and I think I cut too much off. Both of them are tropical hibiscus, about 2 feet tall. One is in a container (about 5 years old), and the other is in the ground (planted in the ground last summer). Oh, the one in the container got repotted and root pruned as well. They were both doing fine before I pruned them. What can I do to nurse the plants back to health? Usually around this time of year in San Diego, California these plants are having growth spurts, so I know something is wrong. Please help!
