Nel's Tongue Plant problems — and how to fix them
Nel's Tongue Plant (Glottiphyllum nelii) 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 from overwatering
The most common issue; caused by watering before soil is completely dry. Reduce watering frequency and improve drainage immediately.
Leaf stretching (etiolation)
Caused by low light. Move the plant to the brightest available spot with direct sun.
Mealybugs
Inspect leaf crevices for white fluffy deposits. Treat with isopropyl alcohol on a cotton swab or diluted neem oil spray.
No flowers
Requires a distinct dry, cool winter rest to initiate autumn flowering. Ensure it receives reduced water and cooler temperatures (10-15°C) in winter.
Sunscald
When moving from lower light into intense direct sun, acclimatise gradually to avoid bleached or brown patches on leaves.
