Troubleshooting
Lamb's Stomatium problems — and how to fix them
Lamb's Stomatium (Stomatium agninum) 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 is the main cause of failure. Allow complete drying between waterings.
Etiolation in low light
Leaves become elongated and plants fail to flower without adequate sun. Move to a south-facing window.
Mealybugs
White cottony deposits in leaf axils are a sign of mealybug infestation. Treat with alcohol or dilute neem oil.
Failure to open flowers
Flowers are nocturnal; they open in the evening and close in the morning. This is normal behaviour, not a problem.
Poor flowering
Cool, dry winter rest and adequate summer sun are the key triggers for reliable flowering.
