Desert Rose leaf tips dying
I've had this desert rose (my favourite plant) for over a year I think. It started well last year, but then all the leaves started turning brown at the tip. This spring I repotted it into a bigger pot, moved it to a south facing window (sliding door off kitchen) fed it, and watered it more frequently. Next thing I know, it's twice as big, all the old, half-brown leaves had fallen off and given way to big, beautiful leaves about 3 times the size. This has lasted for about a month, but now the ends of many of these big new leaves are dying. I haven't changed anything since it responded so well. Any ideas??
