<p>Nangka thrives in various environments, ranging from dense forest to open areas, and can flourish at elevations below 1,000 meters above sea level. The tree typically begins to bear fruit 3 to 6 years after planting, with continuous fruit production year-round. Monkeys and squirrels are particularly fond of the half-ripe fruit. Propagation of the tree is done through seeds.</p> <p>Female and male flower heads are frequently located on the same twig. Additionally, it has been observed that female flowers are typically found on cauliflorous shoots, while male flowers are formed on shoots at the edge of the canopy. These flowers are thought to be primarily pollinated by wind, although a recent study by Gardner et al. (2018) suggests that both fungus and insects play a role in pollination. The study also demonstrated that insects are attracted to the scents of both types of flowers, aiding in pollination.</p> <h2>References</h2> <p><b>Gardner EM, Gagne RJ, Kendra PE, Montgomery WS, Raguso RA, McNeil TT & Zerega NC. </b> (2018).
