Water Calathea carlae thoroughly when the top 2-3 cm of soil feels dry. Use filtered or distilled water to prevent mineral buildup, which can cause leaf tip browning. Avoid overwatering, as this can lead to root rot.

Allow excess water to drain away completely.

Prune Calathea carlae to remove any dead, damaged, or yellowing leaves. Use clean, sharp scissors or pruning shears. Pruning helps maintain the plant's aesthetic appeal and encourages bushier growth.

Avoid heavy pruning, focusing instead on tidying up the existing foliage.

Calathea carlae is primarily propagated by division. Carefully divide the root ball into smaller sections, ensuring each section has healthy roots and shoots. Replant these divisions into suitable potting mix.

This is best done during repotting in spring.

Repot Calathea carlae every 1-2 years or when it becomes root-bound. Use a well-draining potting mix, such as a blend of peat moss, perlite, and compost.

Choose a pot that is only slightly larger than the current one to avoid waterlogging.
