Propagate by softwood grafting, air layering or epicotyl grafting. For the nursery, soak seed nuts in water for 12–24 hours and use only those that sink. Dig 45 x 45 x 45 cm pits and fill with soil, 10 kg FYM and 1 kg neem cake. Spacing: 7 m each way (200 plants/ha); high-density planting at 5 x 4 m (500 plants/ha), pruning interlocking branches in July–August.
