- Preserve and cultivate specimens in backyards, family gardens, and agroforestry projects.
- Propagate the species by fresh seeds or grafts to maintain genetic variability and fruit quality.
- Use modern biotechnology methods, such as cultivation vitro and cryopreservation, to conserve germplasm of high medicinal and agricultural value.
The tree tolerates deep, well-drained soils well, resisting several months of drought and low temperatures if well established, but requires protection during its early stages. It prefers mild climates, although it can adapt to different conditions if properly cared for.
