Watering, pruning, propagation, and repotting details from plant data
Keep the soil consistently moist but not waterlogged. Water thoroughly when the top 2-3 cm of soil feels dry. In warmer conditions, more frequent watering may be necessary.
Reduce watering slightly during cooler periods, but never allow the soil to dry out completely.
Prune to remove any dead, damaged, or discolored fronds. This can be done at any time of the year. Trimming encourages healthy new growth and maintains the plant's tidy appearance.
Use clean, sharp shears to prevent disease spread.
Propagation is typically done by dividing established plants. In spring, carefully separate clumps of rhizomes with attached fronds. Pot each division into its own container with well-draining potting mix.
Keep moist and in a warm, humid location until new growth appears.
Repot every 2-3 years or when the plant becomes root-bound. Use a well-draining potting mix, preferably one formulated for ferns or containing peat and perlite.
Choose a pot that is only slightly larger than the current one to avoid overwatering.
