sun scorch on Stapelia
Quick answer
If your Stapelia has sun scorch, the most likely cause is: Stapelia pulvinata is adapted to bright sun but its hairy, velvety stems scorch when they are moved into stronger sunlight too quickly, especially during a hot, stuffy spell; the damage shows as brown scorch marks on the stem surface, often combined with shrivelling, and the marks are permanent on that segment.
Start here:
- 1. Move the scorched Stapelia out of bright midday sunlight into a position with light shade, and give it plenty of fresh air during hot weather.
- 2. Reintroduce the plant to stronger sun gradually over about two weeks so the velvety stems can acclimatise without further burning.
