Troubleshooting
Bluff Lettuce problems — and how to fix them
Bluff Lettuce (Dudleya farinosa) 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
The most common cause of loss. Dudleya farinosa must be kept nearly dry during warm months. Move containers under cover or stop all watering from June through September.
Aphids on flower stalks
Yellow-green aphids commonly attack the spring flower stalks. Blast with a gentle stream of water or apply insecticidal soap, avoiding the main rosette.
Etiolation
Stretched, pale growth indicates insufficient light. Move to a brighter location; the distorted form will not recover but new growth will be compact and tighter.
