OK so my wife bought me 3 dinner plate hibiscu plants. MY research shows them to be native to Massachusetts and particularly to swampy wet areas. Having a wet area in the yard I confidently placed them there. The stalks grew well to about 13 or 14 inches...and the leaves fed the bugs very well. First year..no blooms. QUESTION....Do I cut them down to the ground and mulch them for the winter? Do I dig them up and move them inside? I will post another thred soon about my other hibiscus and shall post a photo......those will come indoors soon but I am sure I need to prune them back.
