hardy (pernnial) hibiscus

I've got 4 of them and they get huge but I think one needs some fertilizer.
what kind of fertilizer do I use?
Thanks. I'm in zone6b

Just a simple garden fertilizer. I use 10-10-10 from the garden center for my flowers and shrubs.

I, for one, don't believe that flowers need the special attention and fertilizer care that veggies do. Compost for the veggies, general fertilizer for the flowers.

I had hardy hibiscus in a protected area, that didn't get much wind or rain. The plants got white flies and suffered terribly, no matter what I used on them. Finally one year I dug them up while they were dormant and gave them away. At their new home, they don't have a white fly problem.
