Q.Coffee Plant Black Leaves and Falling Off
It was healthy till I brought it in the fall. The leaves started to turn black and fall off. I see no bugs, and the rest of the plant is healthy.

It sounds like you have a fungus, possibly sooty mold. Treat the plant with a fungicide. I personally like neem oil because it will kill fungus and any pests that happen to be around as well. Here is more info on neem oil:
