Christmas Cactus Leaves Turning Purple and Thin
I purchased my x-mas cactus about 8 months ago and it had been doing wonderfully. It bloomed beautifully this past holiday season with dozens of flowers. Recently, the leaves have become very thin and are turning a purplish color. I am thinking it may be time to repot it as it was a tight squeeze when I first planted it. It is in a 3 inch square pot that is about 4 inches deep. I have been waiting until it dries out to water it and this had been working well prior to the bloom. I've heard different theories about the purple color and wasn't sure what to follow. Some have suggested under-watering, over-watering, root rot, or root constriction. Any input on what may be causing this?
