Thank you for your help, in advance. We have a hibiscus, in a pot kept inside, in a semi-greenhouse. It has about 5% of yellow leaves, the large leaves. I have given it some "Miraclegrow", diluted, does not seem to help. It is about 3' tall in the original pot of about 4 years ago. No blooms. . . any ideas? Thanks again!
