Keep the soil consistently moist but not waterlogged, especially during the growing season. Reduce watering in cooler months, allowing the top few centimeters of soil to dry out between waterings.

Proper drainage is crucial to prevent root rot, as this species dislikes soggy conditions.

Pruning is generally not required for Phyllocladus hypophyllus, as it maintains a natural, attractive form.

If necessary, remove any dead, damaged, or crossing branches in late winter or early spring before new growth begins. Avoid heavy pruning.

Propagation is best achieved through seeds, which require stratification. Sow seeds in a well-draining seed-starting mix and keep them consistently moist and cool. Germination can be slow and erratic.

Cuttings are difficult to root and rarely successful.

Repot young plants every two to three years, or when they become root-bound, typically in early spring. Use a well-draining potting mix. Mature specimens can be left in their pots for longer periods.

Ensure the new pot has adequate drainage holes.
