So my Christmas cactus was seemingly healthy...growing new little nodes until today, when two of the bigger sections (growing off one base piece) just up and FELL OFF...I took the base piece out and it was dry and very sick looking (photo attached). But the top pieces were nice and green. I only have one small section left and I really hope it doesn't die off too! Any help with what happened or how to prevent/correct it would be appreciated!
