The black is a fungus...but the cause is an insect...
Sooty mold. black and Sticky is caused by several insects.
All sucking mouth part type insects.
Most often Aphids, mealy bug or scale.
All can be treated with a systemic insecticide and a direct spray of Horticultural Oil.
Take time to closely examine the plant to determine which of the insects that it is before you choose a pesticide! Some are more insect specific than others.

Read the info above.
Sounds like Sooty Mold. I have had pretty good luck using a high powered hose nozzle on Gardenias. It has lessened the sooty mold and the plant is doing much better.
Good luck.
