What spacing and how many grafted jackfruit plants per acre for a commercial orchard?

Traditional seedling jackfruit trees become huge and need very wide spacing, but for a commercial orchard with grafted dwarf or medium clones you can plant closer and manage canopy size by pruning, which raises trees per acre and makes harvesting easier. Conventional wide spacing gives only a small number of trees per acre, while higher density grafted planting with pruning can fit more, so the exact figure depends entirely on your variety, soil and how aggressively you will prune; confirm it with your horticulture department. Plant grafted material at the onset of the monsoon in good pits with organic matter and ensure drainage. Use the open early years for intercrops since jackfruit is slow to fill space. Regular formative pruning to keep trees low and open is the key to a manageable commercial orchard.
