Calathea Majestica Royal Blue problems — and how to fix them
Calathea Majestica Royal Blue (Goeppertia majestica 'Royal Blue') 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.
Brown edges on the long leaves
The large thin leaves show hard-water and low-humidity damage readily. Use soft water and keep humidity high.
Leaves curling inward
Indicates thirst or dry air, sometimes cold stress. Check soil moisture and move away from drafts and radiators.
Faded blue cast and pinstripes
Excess direct light bleaches the colour; too little flattens it. Position in bright, filtered light to preserve the tones.
Spider mites
Dry air invites mites that stipple and web the undersides. Raise humidity, shower the foliage and treat with insecticidal soap if found.
