White Tabernaemontana problems — and how to fix them
White Tabernaemontana (Tabernaemontana alba) 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.
Leaf yellowing and drop
Yellowing lower leaves often indicate overwatering or waterlogged roots. Improve drainage and reduce watering frequency. General yellowing of multiple leaves can also signal nutrient deficiency — apply a balanced fertiliser and check soil pH is below 7.0.
Mealybugs and aphids
Common sap-sucking pests, especially in warm indoor conditions. Inspect leaf undersides and stem axils regularly. Treat with insecticidal soap or neem oil applied every 7–10 days until clear. Maintain good air circulation to reduce pest pressure.
Weak, leggy growth indoors
Caused by insufficient light. Move to the brightest available location or supplement with a grow light providing 12–14 hours of bright indirect light daily. Prune leggy stems back to a healthy node in spring to encourage bushy regrowth.
