: We have two gardenia plants. One is fine. The other is covered with sooty black mold. For the past year, I've washed the leaves with dish soap, but the mold keeps reappearing.

Hi Dolly,

we have similar problems in Hilo, and I think the problem is green coffee scale. There also is a white scale on some gardenias in this area. I have only seen the black bugs recently but we have had sooty mold for a long time. I usually just let the rain wash it off and don't bother with it. As for spraying I have only tried a mixture of a mild dish detergent and water. It helps some, but I have never managed to get rid of it completely - scales are notorious for that.


Aloha,

Maren, in Hilo.
