Notice how some of my hibiscus leaves are deep, dark green, and some are very yellowish? I use Os-mo-cote (sp?) fertilizer. It's a time release product, so should I throw on some more? Or some more coffee grounds or what? I'm thinking this thing has just gotten way too big and is probably sucking everything out of the soil, but it's probably too late (hot) to try to divide it up now. I'll do it in late fall when I cut it back to the ground. Your thoughts, please.
