Troubleshooting
Ox Tongue Plant problems — and how to fix them
Ox Tongue Plant (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 rot
Caused by excessive watering or compacted, poorly drained compost. Repot into fresh dry medium and reduce watering.
Leaf discolouration
Red or brown tints indicate too much direct sun. Move to a position with more filtered light.
Mealybugs
Hide in leaf axils and on roots. Treat above-ground infestations with isopropyl alcohol; drench soil if root mealybugs are suspected.
Sluggish growth
Slow growth is normal for Gasteria; provide optimal light and seasonal watering to maximise growth rate.
Brown leaf tips
Can indicate fluoride sensitivity. Use filtered or rainwater if tap water fluoride levels are high.
