Due to the devastating of papaya ring spot virus, papaya plants can only be grown in the net house with a special bending plant type to control the plant height and easy for harvesting. Papaya plants can grow on the same piece of land for 2-3 years, and then, they should be replanted again. Most seedlings came from asexual reproduction such as grafting, cutting, or tissue culture, replanting plants by seeds is not very common but is feasible.
