Troubleshooting
Chinese Ixora problems — and how to fix them
Chinese Ixora (Ixora chinensis) 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.
Iron chlorosis (interveinal yellowing)
The most common issue — new leaves yellow between the veins while veins stay green. Caused by soil pH above 6.5 making iron unavailable. Acidify soil with sulphur amendments, use rainwater, or apply chelated iron. Check and correct pH before adding more fertiliser.
Bud drop
Flower buds abort and fall before opening, typically due to dry air, inconsistent watering, temperature fluctuations, or being moved mid-bud. Maintain stable humid conditions and avoid moving the plant when in bud. Do not let soil dry completely.
Sooty mould / scale insects
Sticky honeydew from scale or mealybug infestations leads to black sooty mould on leaves. Wipe leaves with a damp cloth, apply horticultural oil or insecticidal soap to eliminate the insect source, and ensure good air circulation. Treat monthly until clear.
