How & when to prune a tropical hibiscus?
I have two tropical hibiscuses. I have been unable to find the names to either of them. One has small blooms with a hot, hot, hot pink center with white edges. The other has the same colorations, but the blooms are almost double in size & is a double flower. In my zone, they have to be brought inside the house during the winter. The double hibiscus is getting huge. When should I prune it? Is it even recommended to cut back a tropical hibiscus?
