Sooty Mold grows on the secretions of plant sucking insects and mites. It does not harm the plant except insofar as it blocks light from the surface of the leaf
thereby interfering with photosynthesis. It may be removed with soap
and water and it's return prevented by identifying and controlling the
insect or mite that is most likely infesting your plant.
White flies love Gardenias; the sap excreted by the white flies turns into a black, sooty mold layer on the leaves that is unsightly. If your gardenia suffers from this black layer, simply take a hose with a strong sprayer attachment and blast each individual leaf with a sharp stream of water. Hold each leaf in the palm of your hand as you blast the water onto the mold and it will peel this black layer right off. It does NOT harm the leaf at all, in fact your Gardenia will thank you with the increased vigor. Don't forget to blast the stems as well. (Do this before the flower buds appear.)
Add a systemic granular insecticide to the soil regularly to keep the white flies at bay.

How do you reproduce gardenia plants?
A gardenia is an evergreen acid loving plant. If you plan to keep it indoors, then be prepared to give it afternoon partial sun. It likes the fertilizer for azalias and rhododendrons, and doesn't like wet feet. The occasional yellow leaf is normal, in fact, the plant may have up to 10% yellow leaves during flowering. Do not be alarmed as this is normal behavior for the gardenia. If you live in a moderate climate, you can grow this plant outdoors. It loves a shade garden, and will happily blend in with azalias. My gardenia bush is about 18 years old, and is 8 feet tall and 15 feet around. I live in zone 9.
