Wheat cockscomb problems — and how to fix them
Wheat cockscomb (Celosia spicata) 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.
Root rot
Caused by overwatering or poor drainage. Plants wilt suddenly despite moist soil. Improve drainage and reduce watering frequency; avoid letting pots sit in standing water.
Aphid infestations
Soft new growth and flower buds attract aphids, causing distorted tips. Knock off with a strong water spray or apply insecticidal soap. Check undersides of leaves regularly.
Botrytis (grey mould)
Fuzzy grey mould on flowers and stems in humid, crowded conditions. Improve air circulation by spacing plants 25–30 cm apart, remove affected tissue promptly, and avoid wetting foliage.
