Aglaonema Pictum Tricolor problems — and how to fix them
Aglaonema Pictum Tricolor (Aglaonema pictum 'Tricolor') 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 soggy, poorly-draining mix leading to root rot. Let the top 2-3 cm dry between waterings and ensure the pot drains freely.
Crispy brown leaf edges
Air too dry, or salt/mineral buildup from tap water or fertiliser. Raise humidity to 50-70% and water with filtered or tepid low-mineral water; flush the mix occasionally.
Faded or reverting variegation
Too little light dulls the camouflage pattern and causes leggy growth. Move to brighter indirect light — but never harsh direct sun, which scorches.
Scorched, bleached patches
Direct sunlight burns the variegated leaves. Filter the light or move a little further from the window.
Cold damage (grey/black blotches, wilting)
This is a warm-loving tropical; exposure below about 15°C (60°F) or to cold draughts damages foliage. Keep it warm and away from chilly windows and AC vents.
Pests (spider mites, mealybugs)
Dry indoor air invites spider mites; mealybugs hide in leaf joints. Inspect regularly and treat with insecticidal soap or neem, raising humidity to deter mites.
