Water Oldfieldia dactylophylla moderately, allowing the soil to dry out slightly between waterings. Avoid waterlogging, which can lead to root rot.

Reduce watering significantly during the dormant winter months to prevent excessive moisture.

Prune Oldfieldia dactylophylla primarily to maintain its shape and size or to remove dead, damaged, or crossing branches. Light pruning can be done in late winter or early spring before new growth begins.

Avoid heavy pruning.

Propagation of Oldfieldia dactylophylla is typically done by seeds, which require stratification. Alternatively, semi-hardwood cuttings can be taken in summer and treated with rooting hormone, then planted in a well-draining medium.

Repot Oldfieldia dactylophylla every 2-3 years, or when it becomes root-bound. Use a well-draining potting mix. Repotting is best done in spring before the start of the active growing season to minimize transplant shock.
