Troubleshooting
Few-fruited Tongue Plant problems — and how to fix them
Few-fruited Tongue Plant (Glottiphyllum oligocarpum) 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
Overwatering or waterlogged soil rapidly causes rot. Allow complete soil dryness between waterings and use gritty, fast-draining mix.
Etiolation
Insufficient light causes pale, elongated leaves. Reposition to a sunny window or supplement with a grow light.
Mealybugs
White waxy deposits in leaf bases indicate mealybug infestation. Remove by hand or treat with neem oil.
Lack of flowering
Cool, dry winter rest is needed to trigger autumn bloom. Reduce water and keep cooler (10-14°C) in winter.
Leaf spotting
Dark spots can appear from cold water on leaves in bright sun. Water at soil level to avoid splashing foliage.
