Royal Ferns thrive in consistently moist soil. Water regularly, especially during dry periods, ensuring the roots never dry out. Maintain a bog-like environment if possible.

Reduce watering slightly in winter but never allow the soil to become completely dry, as this can harm the plant.

Pruning is primarily for aesthetic purposes and removing dead or damaged fronds. Cut back any brown or yellowed fronds at the base of the plant in late winter or early spring before new growth begins.

This tidies up the plant and encourages vigorous new development.

Osmunda regalis can be propagated by dividing established clumps in early spring. Carefully dig up the plant and separate it into smaller sections, ensuring each section has roots and at least one bud.

Replant divisions immediately into moist, well-draining soil.

Repotting is rarely necessary for Royal Ferns as they are slow-growing and prefer to be undisturbed. If repotting becomes essential due to overcrowding, do so in early spring.

Choose a larger pot and use a rich, moist, well-draining soil mix, handling the roots gently.
