Maintain consistently moist soil, as Thelypteris confluens thrives in wet conditions. Water frequently, especially during warmer months, to prevent the soil from drying out.

In its natural habitat, it often grows in standing water or saturated soil, so aim for a similar environment.

Prune away any dead, damaged, or discolored fronds at the base of the plant. This is best done in late winter or early spring before new growth emerges.

Minimal pruning is generally required; the fern maintains a neat appearance naturally.

Propagation is typically done through division of rhizomes in early spring. Carefully separate sections of the rhizome, ensuring each piece has at least one bud.

Alternatively, spores can be collected and germinated on a sterile medium, though this is a more advanced method.

Repot Thelypteris confluens every 2-3 years, or when it becomes root-bound. Use a well-draining, yet moisture-retentive potting mix, ideally incorporating peat or compost.

Repotting is best done in early spring before active growth begins to minimize transplant shock.
