Keep the soil consistently moist, especially the crown. Water frequently, ensuring good drainage to prevent waterlogging. In drier periods, increase watering frequency.

Avoid letting the substrate dry out completely, as this can stress the plant.

Pruning is generally not required for Dicksonia sellowiana. Remove any dead or damaged fronds by cutting them at the base of the trunk. This helps maintain a clean appearance and prevents potential disease issues.

Avoid cutting into healthy tissue.

Propagation is primarily achieved through spores, which requires specific conditions of high humidity and consistent moisture. Division of the rhizome is also possible but challenging and less common for this species.

It is a slow process.

Dicksonia sellowiana is a tree fern and does not require traditional repotting in pots. It is typically planted directly in the ground or in very large, custom containers.

If a specimen outgrows its space, transplanting to a larger or more suitable location is necessary.
