Troubleshooting
Imperial Green problems — and how to fix them
Imperial Green (Philodendron 'Imperial Green') 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.
Yellowing lower leaves
Usually overwatering or poor drainage. Let the top third of the soil dry out and confirm the pot drains freely.
Brown crispy leaf edges
Low humidity or fertiliser salt buildup. Raise humidity and flush the soil with plain water every few months.
Leggy, small new growth
Insufficient light. Move to a brighter spot with bright indirect light to restore full, broad leaves.
Soft, blackened crown
Crown rot from water sitting in the rosette. Water at the soil, not the centre, and improve airflow.
