I have a client consultation today. She is worried about her Christmas cactus. No bug issues, but this plant is 50+ yrs old. I need to know if repotting or trimming is a good idea this time of year. I don't want to hurt her plant. I am up for both if it going to help the plant. I hear February- April is the best for both, but I do want to help this person troubleshoot threw her options. We have discussed trimming to propagate, but I'm concerned with disturbing this plant in its peak blooming season. Love to hear some info:)
