Troubleshooting
Bertolonia Marmorata problems — and how to fix them
Bertolonia Marmorata (Bertolonia marmorata) 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 leaves in open air
Low humidity is fatal to this plant outside an enclosure. Grow it in a terrarium or sealed case at 70%+ humidity; ordinary room air will not keep it alive long term.
Leaf spotting or rot
Water sitting on the velvety leaves, or stagnant air, causes spots and crown rot. Water at the soil only, use clean low-mineral water, and ensure gentle air movement in the terrarium.
Bleached or scorched foliage
Too much light, especially direct sun, fades the marbling and burns the delicate surface. Provide low-to-medium indirect light or a dim grow light.
Stalled growth or rot from cold/wet
Cold temperatures below ~16°C combined with constant wet trigger rot and stagnation. Keep it warm and stable, and use an airy, fast-draining substrate.
