The growth of the tree is typically slow, with seedling height increasing by approximately 60 cm per year. The juvenile phase can last for 4-5 years or even longer. In regions with higher latitudes, shoots primarily grow in the spring, flowers bloom throughout the summer, and pods ripen in the spring. The period from flowering to harvest spans about 8 months, with fruit ripening mainly between June and September. In East Java's monsoon climate, the tree undergoes leaf changes towards the end of the dry season. While some trees may temporarily lose their leaves, they typically remain foliated. The emergence of flowers on new shoots coincides with the leaf change, with the flowers providing nectar and likely being pollinated by insects. Self-pollination also leads to the development of seeded pods.

Asam Jawa can be propagated through seeds or cuttings, with seeds remaining viable for several months and taking approximately 1-2 weeks to germinate. It is important to ensure that seeds are thoroughly cleaned and removed from the pulp before germinating.

Shield and patch budding, along with cleft grafting, are efficient and dependable techniques that are currently employed for large-scale propagation in the Philippines. These methods are most effective during the cool and dry months of November to January. The budded or grafted trees are then transplanted into the field at the beginning of the rainy season (typically May to June in the Philippines) with a recommended spacing of 8-10 meters.
