Q.Christmas Cactus Problem
I have a problem with my Christmas cactus. It is healthy, but it also has tiny black seed-type things on the leaves that must pop off because I have them on the wall, counter, and even the ceiling around the plant. These stick to the surface they land on and are very hard to get off. Is this an aspect of the plant or perhaps a pest on the plant? Also, can I keep the plant outdoors in a Zone 9 for the spring/summer?

Try treating the plant with neem oil. Here is more info: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
