Plants wither and shed their leaves due to drought, lack of water, and the spring can recover again. Trees that have been infected with the virus cannot be saved.

To overcome the above harms, when planting papaya, we need to pay attention to overcome the following stages:

- In addition to choosing good soil, little dirt and dirt to avoid root nematode, rainwater is quickly drained in summer, also convenient for watering in the Autumn and Winter season. Papaya garden should be arranged toward the north and northeast wind. If there is no need for windbreak trees. In mountainous areas, avoid growing papaya in the valley or where there is frost.

- When planting papaya, need to fertilize many organic and good fertilizer. Swings are very resistant to feces. The more good fertilizer the more fat the tree is, the darker and more leafy green, the more favorable conditions for the tree to grow. Each tree always has a number of leaves 30-35, then the water is stable. In addition, trees are good enough to be resistant to cold and pests later.

- In the autumn and winter, it is necessary to water regularly to keep the plants moist, and it is not always possible to leave the garden ground white. Each time watering can be sprayed like a shower or slap the water into the groove of the bed to allow the soil to absorb enough water, remove the excess water. Combine spraying with 2-3 times per month of copper or copper oxide. These substances both provide calcium and provide copper, which helps the chlorophyll plant, limiting the white leaf disease or poor green.

The phenomenon of broken papaya is caused by aphids. This type of aphids is concentrated in clusters like a snail-shaped figure, half as small as a millet, not moving. They are colored like bark colors, so it is difficult to detect. Aphids sweep the plastic to suck the stem and create wounds, paving the way for pathogens to invade stem rot, then collapse. When detected, just use a strong cloth to wipe it, the bug will die. Preventing early plants will prevent death.

Papaya is a nutritious fruit, it contains up to 0.6% protein, 0.1% fat, 8.3-8.5% sugar, 60-20% vitamins B and C, Especially containing up to 2,000-3,500 units of vitamin A, 10 times higher than bananas, pineapples, 5 times more avocado, guava and nearly double mango. However, if the tree is severely ill, the fruit is bitter. There are many papain in papaya fruit. This type of yeast softens the bones, so sick or cold people should abstain from pain.
