Calathea Undulata 'Wavestar' problems — and how to fix them

Calathea Undulata 'Wavestar' (Goeppertia undulata 'Wavestar') 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.

Crispy, browning leaf edges

Low humidity or hard, fluoridated water. Switch to rainwater or distilled and keep humidity high, ideally in an enclosed space.

Curling leaves

Underwatering or dry air. Keep the rootball evenly moist and raise humidity until leaves relax.

Loss of leaf contrast

Too much direct sun fades the silver feathering. Move to brighter indirect light, out of direct rays.

Spider mites

Dry air invites mites on the small leaves. Increase humidity, rinse foliage, and treat promptly with insecticidal soap.
