Q.My Carolina Jasmine Bush Is Sick With A Black Mold On The Branches And Leaves.
My Carolina Bush is an older bush which has been healthy until last year. I began treating it with Daconil, Fungicide 3, and Neems oil, but none of these three is clearing up the mold. Help please, what should I do to make this a healthy bush again?

It could be sooty mold, which usually means you have an insect problem like aphids. Check for those. If you have aphids, for example, they produce a honeydew, which in turn feeds sooty mold. You can try hosing them off. If that doesn't help, you can try an insecticidal soap or a product labeled for aphid control. Here is info:
After your plant finishes blooming, I would cut it back by 1/3 to 1/2. That should help. Thinning it out will help with air circulation
