Yellowing Leaves on Hibiscus
I have been having occasional problems with yellowing leaves on my hibiscus. I have five of them planted in a row. The two that are partly shaded don't get many yellowed leaves but the other three get several. A couple of weeks ago I read a tip on adding 1 cup of vinegar to one gallon of water to help this and other acid loving plants. You just apply it to the soil at the base of the plant. You do NOT pour it on the leaves. It actually worked...and pretty quickly! I was really happily surprised. All my hibiscus are now nice and green and the yellow leaves are gone. I just thought I'd pass the tip along in case anyone else was having that problem.
