Q.I have a christmas cactus and it’s emitting sap all around it I don’t remember this happening before? What could be happening
to it? The plant is producing beautiful flowers so I don’t think that it’s dying.

It sounds like you have a pest that produces honeydew. Look carefully at the plant – do you see small insects in the folds or new shoots of the plant, or perhaps oval shaped bumps? The insects could be mealy bugs, aphids, or white fly. The bumps could be scale. These insects usually congregate in groups, and all suck the sap from the host plant. The sticky stuff is called “honeydew” and that is what is excreted by the insect.
Isolate your plant from other plants and treat with Neem Oil.
