Troubleshooting
Jungle Geranium problems — and how to fix them
Jungle Geranium (Ixora coccinea) 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 chlorosis (yellowing between veins)
The most common Ixora complaint, caused by alkaline soil or iron deficiency. Lower soil pH with an acidifying fertiliser and apply chelated iron; avoid hard tap water where possible.
Few or no flowers
Almost always insufficient light. Move to full sun or the brightest window. Cold drafts, overpruning at the wrong time, or letting the soil dry out can also cause bud drop.
Sap-sucking pests
Aphids, scale, mealybugs, thrips, and spider mites are common, especially indoors in dry air. Inspect leaf undersides and treat promptly with insecticidal soap or neem oil.
Sooty mould
Black sooty film grows on the honeydew left by aphids, scale, and mealybugs. It is harmless itself but signals a pest infestation; control the insects and wipe leaves clean.
Bud or leaf drop
Triggered by sudden temperature swings, cold below 10°C (50°F), drafts, or the soil drying out completely. Keep conditions warm, stable, and evenly moist.
Fungal leaf spot
Wet foliage encourages fungal spotting. Water at the root zone rather than overhead, improve air circulation, and avoid splashing the leaves.
