christmas cactus - divide or cut back or both?
My christmas cactus has gotten so big that I can barely lift it, it's 5 feet across. It looks like there are 2 separate plants in the pot - there were 3 but one rotted and died last year. I was thinking of dividing it to make it easier to handle but then I'll need twice as much room.
I have never cut it back and wonder if I should or if that would affect its blooming next year?
I transplanted it once when I got it 5-6 years ago but it didn't need it.(the lady who gave it to me said it was root bound, but it wasn't)
I had a hard time transplanting it and damaged and lost alot of the branches, that was when it was small, now that it's huge I am leary of trying it again so all I do is replace 3-4 inches of top soil every year.
Any help or ideas would be appreciated.
