Troubleshooting
Ox Tongue problems — and how to fix them
Ox Tongue (Gasteria bicolor var. liliputana) 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 and crown rot
The leading killer, caused by overwatering or a water-retentive mix. Leaves go translucent, soft and yellow at the base. Always let the soil dry fully and use gritty, free-draining compost.
Etiolation in low light
Insufficient light makes the compact rosette stretch, pale and lose its spotted markings. Move to brighter, indirect light to restore tight, well-coloured growth.
Sunburn
Sudden exposure to intense direct summer sun scorches dull brown or white patches onto the leaves. Acclimatise gradually and shade from fierce midday rays.
Mealybugs
White cottony clusters hide in the crowded leaf axils and between offsets. Dab with isopropyl alcohol on a cotton bud and isolate affected plants.
