I was given 2 large bags of hibiscus fertilizer. What other plants can this be used on besides hibiscus? Thank you.

You can use it on just about anything that requires lots of nitrogen and potassium. These are taken up quick by the hibiscus, so they need more of it than usual. When you use it, just be on the lookout for phosphorus deficiencies. This is not likely to happen, but can in plants that have a need for more phosphorus.
