Water
Water regularly, especially during establishment and dry periods, allowing the soil to dry out slightly between waterings. Reduce watering in cooler months to prevent waterlogging, as established trees are relatively drought-tolerant.

Watering, pruning, propagation, and repotting details from plant data
Water regularly, especially during establishment and dry periods, allowing the soil to dry out slightly between waterings. Reduce watering in cooler months to prevent waterlogging, as established trees are relatively drought-tolerant.
Prune to shape the tree, remove dead or crossing branches, and improve air circulation. Heavy pruning is best done after flowering. For fruit production, thin out crowded branches to encourage larger fruit development.
Propagate primarily through seeds, which benefit from scarification or soaking to improve germination. Cuttings can also be taken from semi-hardwood, but success rates can be variable.
Young plants may require repotting every 1-2 years into a slightly larger container. Mature trees in the ground generally do not require repotting. Ensure good drainage in the pot.
