One of my hibiscus plants has ugly black spots on the leaves (taking up most of the leaf on some) and they are now turing kind of dry and brittle. Anyone know what I can do to save it? [Roll Eyes] Its a variety of a tropical hibiscus, I have three others that are doing just fine, two are planted in the same bed. This one produces yellow flowers, the two that share the bed are pinks. I had a battle with whiteflies last summer but they never attacked this one, just the one pink and my red. The whiteflies are under control now and I pruned them all a few months ago.

Thanks in advance. [kissies] Any help will be much appreciated. If its a goner or diseased [Eek!] I'd like to get rid of it before it spreads to my other babies.

Women and cats will do as they please. Men and dogs should relax and get used to the idea.

spray with some neem oil.you have a fungas growing.you want to keep it under control so it don't spread to your flowers also.& if you do any trimming at all dispose of the cuts in a non gardening area and clean them cutters.
you don't normally have this problem cause you don't normally get much rain.I'd spray the soil also.& if you add a bit of bakeingsoda will help it hold to the leaves.1 tsp.to 1 gal mixture acorrding to neem oil mixing insctructions...cause my bottle is outside and I don't feel like getting up to read the back of it.
