Black plastic bags can be used as containers (with a size of 18 x 25 cm). You may have to punch 5 to 6 holes close to the bottom and fill with sandy soil. It is advised to poke a piece of wood at the center of the pot/container and insert the basal part of the seedling into the hole. Water the seedling pot immediately and it should be kept under partial shade conditions. The raised seedlings in plastic bags can be transplanted within 6 to 7 months in the main field.

After seedlings are set in the holes, you can refill these with topsoil and applying the water immediately. When it comes to planting spacing, These seedlings may be planted in a rectangular, triangular pattern or square methods at a  distance of 5 meters x 5 meters to 7 meters x 7 meters. The plant density may depend on the pattern followed. In the case of a square system, usually, 1-hectare land can accommodate about 200 to 600 plants whereas 250 to 700 in the triangular system. You need to prepare a layout to know the exact number of plants. The Soursop tends to flower and fruit throughout the year, but in every growing region,  there is a principal season of ripening.

  1. Thanks for the useful information on soursop cultivation! We are planning to expand our business in Sri Lanka where the focus will be on leave production. This project is set up in order to empower local women and children. We plan to set up our own product line ones we have sufficient production.
    My question to you is whether you can see anything about leave production and leave harvest regulations. Do you have any information on this specific topic?

    Hope hearing from you soon!

    Kind regards, Ard
