Water Podocarpus costalis regularly, especially during its active growth period. Allow the soil to dry slightly between waterings. Reduce watering in winter to prevent waterlogged roots, which can lead to root rot.

Ensure good drainage to avoid standing water.

Prune Podocarpus costalis in late winter or early spring before new growth begins. This helps maintain its shape and encourages denser foliage. Remove any dead, damaged, or crossing branches.

Light pruning can be done throughout the growing season to shape.

Podocarpus costalis can be propagated from semi-hardwood cuttings taken in summer or autumn. Use a rooting hormone to encourage root development.

Plant cuttings in a well-draining medium and maintain high humidity until roots form. Seed propagation is also possible but slower.

Repot young Podocarpus costalis plants every 2-3 years, or when they become root-bound. Established plants can be repotted less frequently. Use a well-draining potting mix.

Repot in spring before the active growing season begins. Water thoroughly after repotting.
