Watering, pruning, propagation, and repotting details from plant data
Maintain consistently moist soil conditions, providing water when the top layer begins to dry out. Avoid letting the plant sit in standing water to prevent root rot.
Remove any dead or damaged fronds as needed to maintain plant health and appearance. Minimal pruning is typically required for this species.
Propagation is usually done by division of rhizomes in spring. Spore propagation is possible but more challenging and time-consuming.
Repot every 2-3 years in spring when the plant becomes root-bound. Use a slightly larger pot with fresh, well-draining potting mix.
