Pictured is my Milk Tree. I have had him for a little over a year now and never had any problems. He's grown an exceptional amount and always seemed healthy and happy.
However in the last week one of his branches/stalks (pictured) has wilted, become soft to the touch and broken over at a weak point. I've also noticed that the outer layer of "skin" peels off when handled.
None of the other branches/stalks ste like this and I aim to keep it that way. Does anyone know what could have cause this to happen and what I can do to prevent it from happening to the rest of my plant? I've really become rather fond of him.
Thank you in advance for any and all advice.
