Revolutionize Your Cultivation in Dragon Fruits


Normally farmers in Malaysia planted dragon fruits 3 meter X 3 meter, which makes 500 poles or stake to an acre using about 2,000 cuttings. However, with a high density planting concept (close planting) more plants could be planted to a unit area up to 10,000 plants per acre.
I have seen a farm which practice this technique. In this way yield could be increase tremendously.
