Century Yellow Feather Celosia problems — and how to fix them
Century Yellow Feather Celosia (Celosia argentea var. plumosa) 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 poorly drained soil; ensure containers have adequate drainage holes and reduce watering frequency in cool weather.
Botrytis (grey mould)
Grey fuzzy growth on plumes in humid or wet conditions; remove affected blooms promptly and improve air circulation.
Spider mites
Fine webbing under leaves in hot, dry conditions; mist foliage and treat with insecticidal soap or neem oil spray.
Aphids
Clusters on growing tips distort new growth; knock off with a strong water jet or apply a dilute insecticidal soap solution.
Leggy growth
Result of insufficient light; move to a sunnier position and pinch growing tips on young transplants to encourage bushier habit.
