My poinsettia is getting black on the red leaves and the red and green leaves are falling off. What’s the problem? It otherwise looks healthy.

I would check for pests. It sounds like your plant may have sooty mold, which is a fungus caused by insect pests, like scale or aphids. Neem oil is an effective treatment, both for the pest and the fungus. Here is mroe information: https://www.gardeningknowhow.com/plant-problems/disease/how-to-get-rid-of-sooty-mold.htm
