Troubleshooting
Fine-lined Living Stone problems — and how to fix them
Fine-lined Living Stone (Lithops gracilidelineata) 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.
Rot from seasonal watering mistakes
Watering in summer or during the winter leaf-split phase is the primary cause of plant loss. Strictly follow the seasonal schedule.
Loss of window clarity
Dust or algae on the lobe surface reduces light transmission through the windows. Wipe gently with a dry cloth; never use soap or chemicals on the lobes.
Etiolation
Lobes elongate and lighten if light is insufficient. Provide direct sun or supplement with a full-spectrum grow light at 12-16 hours daily.
Mealybugs in lobe crevice
The narrow crevice between lobes is a favoured mealybug hiding spot. Inspect regularly and treat with isopropyl alcohol on a fine brush.
Failure to flower
Usually caused by insufficient light or incorrect watering. Ensure maximum light in autumn and make sure the plant has had a proper dry summer rest.
