I have had this succulent for about 6-9 mos. After it was planted, I noticed some sand-like granules on some of the blooms. Sadly, it has spread, and the plant looks very sad now. Any suggestions to heal it? The whole plant appears to be turning a dark purple color. It is very beautiful when it’s healthy.
Any suggestions would be appreciated!
The sand-like stuff on the blooms is Aphids, an insect that is feeding off the blooms. You can spray the blooms and try to get rid of them, but often the answer is to cut the blooms off. As for the rest of the plant, a Graptopetalum, it doesn’t look good. I think the plant may already be dead, though it’s hard to tell for sure from the photo. If it was the aphids, it would have to have been a major infestation to do that kind of damage. To me it actually looks like the plant may have suffered sun burn. Was it recently brought outside?
If it is still alive, the best thing you can do is get it afternoon shade, cut off all the bloom stalks, hose it off vigorously, and then spray it with an organic insecticide. We recommend Neem oil, diluted from 100%.
