I have had my desert rose in dormancy since about November now in a cool dark basement which gets about 12 - 15 degrees Celsius (54 - 59 Fahrenheit).
I have not watered it since I put in dormancy and as expected the leaves turned brown and eventually withered away.
But what I did not expect was that the caudex started to get soft and a bit wrinkly. I was expecting it to remain hard. It is not mushy, just starting to get wrinkly and a bit shrunken.
Is this normal, or is the plant toast. If it is normal, how do I awaken it from dormancy and rewater to plump it back up (most likely in about a month or so).
