Troubleshooting
Aglaonema Harlequin problems — and how to fix them
Aglaonema Harlequin (Aglaonema 'Harlequin') 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.
Dull, faded colours
Too little light mutes the yellow and pink; relocate to brighter indirect light to revive the variegation.
Yellowing leaves
Usually overwatering and poor drainage; let the soil dry more and confirm the pot drains freely.
Brown leaf tips and edges
Low humidity or salt buildup from water and fertiliser; raise humidity, use filtered water and flush the soil.
Leaf scorch
Pale variegated tissue burns in direct sun, leaving bleached patches; filter strong light with a sheer curtain.
