Troubleshooting
Sea Lettuce problems — and how to fix them
Sea Lettuce (Dudleya caespitosa) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Summer rot
Watering during summer dormancy is the leading cause of plant death. Stop watering in late spring when temperatures rise and leaf tips begin to shrivel slightly. Resume only in early autumn.
Farina damage
The white powdery coating (farina) protects leaves from intense sun and reflects heat. Handling, splashing water, or rubbing leaves permanently removes it and cannot be restored. Handle only by the base.
Etiolation in low light
Without adequate bright light, rosettes stretch toward the source and lose their tight, ornamental form. Move to the brightest available windowsill or supplement with a full-spectrum grow light.
