According to the planting experience of households in Phuoc Vinh commune, Ninh Phuoc district, custard-apple is quite well adapted to sandy soil as well as hot and dry local climate. Plants are easy to care for, resistant to many types of pests and diseases, cost less to buy fertilizers and fertilizers.
