Q.blooms
My tree is inside sunroom for the winter. It is full of blooms but the blooms have small black spots (like sprinkled with pepper). Have had it for quite a few years and this is the first time. What do I do?

This might be sooty mold, which is a fungus that grows on the honeydew produced by certain insects:

Also check your plant carefully to see if the black spots are alive. They could be black aphids, mites, thrips, or other tiny pests.
