The Portia Tree prefers consistently moist soil, especially when young. Water deeply when the top 2-3 cm of soil feels dry. Reduce watering in cooler months, allowing the soil to dry slightly more between waterings.

Ensure good drainage to prevent waterlogging, which can lead to root rot.

Prune the Portia Tree to shape the plant, remove dead or crossing branches, and encourage bushier growth.

Light pruning can be done anytime, but heavier pruning is best done in late winter or early spring before new growth begins. Remove any suckers that emerge from the base.

The Portia Tree can be propagated from seeds, which should be soaked in warm water before sowing.

Cuttings, typically semi-hardwood, taken in late spring or early summer, also root well in moist, well-draining potting mix. Rooting hormone can improve success rates.

Young Portia Trees benefit from repotting every 1-2 years in spring. Choose a pot that is one size larger with ample drainage holes.

Mature trees require repotting less frequently, perhaps every 3-5 years, or when root-bound. Use a well-draining potting mix.
