Calathea Majestica Sanderiana problems — and how to fix them
Calathea Majestica Sanderiana (Goeppertia majestica 'Sanderiana') 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, crispy leaf edges
The classic calathea complaint, driven by low humidity and hard or fluoridated tap water. Raise humidity and water only with filtered, distilled, or rainwater.
Curling leaves
Indicates underwatering or excessive light. Keep the soil evenly moist and move out of direct sun; leaves that stay tightly furled need attention.
Faded or washed-out striping
Too much direct sun bleaches the pattern, or too little light dulls it. Provide bright, indirect light to keep the pink-to-silver markings vivid.
Spider mites
Dry air invites mites that speckle and web the leaves. Increase humidity, rinse the foliage, and treat with insecticidal soap or neem if they appear.
