Troubleshooting
Javanese Ixora problems — and how to fix them
Javanese Ixora (Ixora javanica) 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.
Chlorosis from alkaline soil or water
Yellowing of new leaves between green veins is the hallmark of iron or manganese deficiency triggered by high soil pH. Test and correct soil pH to 5.0–6.0 with sulphur; switch to rainwater or reverse-osmosis water; apply chelated iron foliar spray as an immediate fix.
Root rot in waterlogged soil
Wilting despite moist soil, yellowing lower leaves, and a foul smell at the root zone indicate root rot. Improve drainage, reduce watering frequency, and if container-grown, repot into fresh acidic mix after trimming dead roots. Treat with a copper-based fungicide drench.
Aphids and mealybugs on new growth
Soft new growth is particularly vulnerable. Aphid colonies on shoot tips cause distorted, sticky foliage; mealybugs produce white wax at leaf axils. Treat with insecticidal soap or neem oil spray applied to all surfaces, repeating every 7–10 days. Encourage natural predators in outdoor planting.
