Anthurium 'Pterodactyl' problems — and how to fix them

The most common killer, caused by overwatering or a dense, water-retentive mix. Use a chunky aroid substrate, a snug pot, and let the top few centimetres dry before watering again.

A sign of humidity that is too low (or, occasionally, salt build-up from over-fertilising). Raise humidity toward 60%+ with a humidifier or pebble tray and flush the soil periodically.

Usually overwatering or waterlogged roots; can also follow sudden cold drafts. Check that drainage is fast and the plant is kept above 15C / 55F, away from cold windows and heat vents.

Mealybugs, scale, thrips and aphids can infest the foliage. Inspect leaf undersides and crevices regularly and treat with insecticidal soap, neem or by wiping with diluted alcohol on a cotton bud.

Too little light mutes the signature pale veins and stalls new leaves. Move to brighter indirect light, but avoid harsh direct sun that scorches the foliage.

Growth naturally pauses or slows in winter as the plant goes semi-dormant. Reduce watering, hold off on feeding, and resume normal care as light levels increase in spring.
