I have a 18 year-old Hibiscus in an indoor container. It recently started dropping leaves - very quickly. I thought it might be root-bound, so I repotted it. While repotting, I noticed a sticky, clear substance (maybe insect honeydew?) a the the point where the leaf connects with the stem. Emerging leaves appear to be mis-shaped and stunted in growth. Is there an insect I can't see?
