Question
Why do some Jade plant leaves get powder like sparkles on them then shrivel and fall off?

Answer
Hi Deborah,

Jades have a thin, waxy outer coating that helps it retain moisture in hot, dry climates. If a leaf dies (from too little water, too much heat or almost any other reason), then the waxy coating crystallizes and that is the sparkley stuff that you see.

In my experience, excessive soil dryness and temps above 90 degrees are the most common causes associated with this symptom. But I would not rely on that as a definitive cause of the leaves dying.

Please let me know if any of this is unclear or if you have any additional questions. If you would like to e-mail some photos to my address below, I may be able to provide some additional insights.
