Troubleshooting
White Ixora problems — and how to fix them
White Ixora (Ixora finlaysoniana) 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.
Interveinal chlorosis (iron deficiency)
Yellow leaves with green veins indicate iron chlorosis, almost always triggered by alkaline soil or water raising pH above 6.5. Lower pH with sulfur drenches or switch to rainwater; apply chelated iron foliar spray for rapid correction.
Bud drop
Sudden bud drop is caused by drought stress, cold drafts, or low light. Maintain consistent moisture, keep plants above 15 °C, and ensure they receive adequate sun. Moving a budding plant often triggers drop.
Scale insects and sooty mold
Soft scale and mealybugs colonise stems and leaf axils, secreting honeydew that leads to black sooty mold. Treat with horticultural oil or neem oil; improve air circulation and avoid over-fertilising with nitrogen.
