Q.How to Repot
I understand February is the best time to repot Christmas cactus. I have two old and two new plants that I would like to combine in one pot. Do I use all new soil or the existing plus some new? Will they all four grow happily together?

As long as the pot is big enough, they will be fine together. You can use both the existing soil and new soil.
