· Hi Joy,
Caring for a Confederate Rose Hibiscus is quite easy. You can fertilize it with a well-balanced shrub and tree or flower food in spring, after the new growth has emerged. I like using Milorganite, a non-burning plant food. On a small plant I would use a couple handfuls of Milorganite. On larger, more mature plants I would broadcast four or five handfuls in an area about 3 feet or so out from the main trunk(3).
Regarding pruning in zone 8, where the top of the plant usually dies back to the ground, I usually prune mine back to short stumps in 6 to 12 inches tall in late winter. Some people might wait until spring when the new growth starts to emerge from the base of the plant. Either way is fine. I don't prune mine during the active growth season as the plant fills out nice and thick on its own.
Because the Confederate Rose Hibiscus is such a leafy plant, it might be necessary to provide supplemental water on a regular basis during prolonged summer droughts until average rainfall resumes.
That's about all there is to caring for Confederate Rose Hibiscus. Hope this info helped.
