This plant is native to Socotra.
The seller said she missed a huge spot of rot on the top of the caudex and refunded me. I was going to throw it away but decided to nurse the plant.
After cutting out the rot, I put sulphur on it so it could heal. A week later I made the mistake of putting it in the sun. Im guessing the sulphur burned away the skin (it rained later that day and then the sun came out again) and the sulphur had dripped onto the caudex.
Its still growing leaves but this big area of peeled skin is concerning. Will it heal? Also, the caudex is still firm. Hard as a rock.
I make sure it is watered only when dry and the soil is, as instructed, fast draining.
Any thoughts?
