I bought a R. Capilliformis and a R. Pilocarpa a few months ago from the home improvement store. They were bought because of their light requirements (basement), and have been doing well, even though its hard to tell because of their painfully slow growth speed. When I bought them, their dirt was soaked, and I figured I would let them dry a little, so they could be on the same, and correct, schedule. I have given them minimal water just because I can't see how they could live without it, however, their soil remains soaked. Their pots are still the original grow pots. I have misted them from time to time while it was warm out to make up for the air conditioning.
Lately I have noticed that the Pilocarpa would occasionally have one of its small stems lying on the counter. Tonight I noticed that it seemed to be getting discolored, and pulled the grow pot out of the decorative metal pot. There was no water in the dish, or the bottom of the metal pot, the roots are not extending out of the grow pot. There was condensation in the bottom of the metal pot, and between the grow pot and the dish. The dirt on this end of the pot is still soaked as well. It is now out of its decorative pot, and I am hoping the roots aren't too damaged. Just handling it the little bit that I have tonight made it lose about 10% of its stems, though they were all from around the perimeter of the pot.
I understand that this is a picky plant to grow, and I know that it is waterlogged. Any suggestions from those familiar with this plant on what my next step should be? I do have some cactus potting soil, but I fear I may send it into shock if I try to change anything. FWIW, the R. Capilliformis is just as soaked, but isn't showing signs of stress yet.
