Hi! I recently transferred the 4 canes I had in a water/pebble pot to soil. I was very careful not to overwater...I went away for a week, and they weren't watered. But now one stalk is entirely yellow, as are most of its leaves, and another has yellowing leaves, but the stalk is still green. It was colder in the apt. than usual - may have been a temp change or a draft? Or maybe it's underwatered? I checked the root tonight - no brown and soggy - gave it a bit of water. What should I do? Should I separate it from the other in that pot? It's still yellow - no browning - any chance I can save it? Thanks for any help! Jude
