Troubleshooting
Long Eye-leaf problems — and how to fix them
Long Eye-leaf (Ophthalmophyllum longum) 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 the summer dormancy period is the most common cause of death. The plant should appear shrivelled in summer — this is normal, not a sign to water.
Etiolation
Long, pale bodies signal insufficient light. Move to a brighter location or supplement with a grow light.
Old body not absorbed
If the previous year's leaf pair does not shrivel and absorb by late autumn, reduce watering; the plant is not ready to receive water yet.
Mealybugs at roots
Root mealybugs are common in mesembs. If growth stalls without obvious above-ground pests, unpot and inspect roots; treat with systemic insecticide.
