Calathea crispy leaves

When large parts of the blades are brittle, check whether there are still firm leaf bases or green shoots at the crown. Dead blades will not recover, but a sound crown can produce replacements.

Rehydrate only if the root ball is dry

Apply water slowly across the mix. If it runs around a shrunken root ball, soak the pot from below until the mix rewets, then remove and drain it. Keep the surface from staying waterlogged and avoid another complete dry-out.

Reduce the load on surviving leaves

Move the plant out of hot sun or heating airflow and remove wholly dead leaves near their bases. Retain partly green blades. Stippled, dusty undersides or webbing need mite treatment; wet soil with soft leaf bases needs a root check. With fewer leaves, the pot may now dry more slowly.
