A while back I had a mass die off of sans in my house, only a few survived. Someone told me they're susceptible to disease and that may have been what happened. Anyway, some of the ones I saved I decided to experiment with and rooted them in water. Now I have sans with water roots in a glass, even one has a little pup growing, however they look like they're in the initial stages of rotting, but with lots of water roots. I drained the water to let them dry out a bit, but I'm not sure what to do with them. Can they be grown in water and I didn't do something right, or do I need to pot them up and let the air roots grow? If I need to pot them up, what's the best way to do so for their survival?
