My Song of India started dropping leaves and the stem is shriveling up. I’ve had it about a year and had repotted it about a week before it started dying. I’ve been following the Plants instructions and don’t think I’m over/under watering. Any chance I can save what’s left? Does trimming the stem below the shriveled part do anything? It was perfectly healthy before the repotting, and I initially thought it was just transplant shock.
