Calathea Zebrina Humilior problems — and how to fix them
Calathea Zebrina Humilior (Goeppertia zebrina 'Humilior') 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.
Browning, crisping edges
Low humidity or chemicals in tap water. Increase humidity and water with filtered, distilled or rainwater.
Yellowing leaves
Often overwatering or poor drainage. Let the top of the soil dry slightly and confirm the pot drains freely.
Velvet surface losing sheen
Dust and direct sun dull the nap. Keep out of harsh light and gently wipe leaves with a soft, damp cloth.
Spider mites and thrips
Thrive in dry indoor air. Inspect leaf undersides regularly, raise humidity, and treat early with insecticidal soap or neem.
