Fresh Look Red Cockscomb problems — and how to fix them
Fresh Look Red Cockscomb (Celosia argentea) 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 / damping off
Caused by Pythium or Fusarium in cold, wet soils; do not sow until soil is warm and ensure sharp drainage.
Leaf spot (Alternaria)
Brown spots on foliage in wet weather; improve airflow and apply a copper fungicide if severe.
Aphids
Cluster on new growth and flower stems; treat with insecticidal soap at first observation.
Spider mites
Occur in hot, dry conditions; apply miticide or increase ambient humidity around plants.
Poor transplanting
Celosia resents root disturbance; sow in cell trays and transplant carefully without disturbing the root ball, or direct-sow after soil warms.
