Troubleshooting
Gasteria (Ox Tongue) problems — and how to fix them
Gasteria (Ox Tongue) (Gasteria carinata) 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.
Root, crown and heart rot
The most common killer, caused by overwatering, water pooling in the crown, or poorly draining soil. Use gritty mix, water only when fully dry, and never let the rosette centre stay wet.
Etiolation / pale, stretched growth
Insufficient light makes the centre pale and the plant stretch and deform. Move to a brighter spot with a couple of hours of gentle direct sun to keep it compact.
Sunburn and red stress colouring
Sudden or harsh midday summer sun scorches leaves and turns them reddish-bronze. Acclimatise gradually and filter intense afternoon light.
Mealybugs, scale and spider mites
Sap-sucking pests hide between leaves and at the base. Inspect regularly and treat with insecticidal soap, neem or 70% isopropyl alcohol on a cotton bud.
Brown leaf tips and patches
Usually from inconsistent watering, soggy soil or temperature extremes. Keep a steady soak-and-dry rhythm and avoid cold draughts or sudden heat.
