How to Grow Papaya? Detailed Guide to Planting Methods and Precautions

Papaya is a fruit that loves warm temperatures, so it is most commonly seen in the coastal regions of our country. Papaya has a rich flavor and high nutritional value, and in recent years its sales on the market have been very good, which is why it attracts so many people to grow it. However, before planting, what everyone most wants to know is surely its planting methods!

How to Grow Papaya

1. Pre-sowing seed treatment: The seeds are best disinfected with a 500-fold dilution of the pesticide thiophanate-methyl, then washed clean and soaked in a 1% baking soda solution for 4-5 hours to improve the germination rate. After removing them and washing them clean with water, place them in a constant-temperature chamber at 32°C to sprout. When the seed coat cracks and the white shows, take them out and sow. If farmers do not have the above conditions, they can soak the seeds in warm water for 12 hours, remove and wash them, wrap them well in a clean towel and place them on the stove top (mainly to keep them warm), check them twice morning and evening and keep them moist. After 4-5 days the seeds crack and show white, and can then be sown.

3. Sowing: Adopt winter raising and spring transplanting, generally carried out in a greenhouse in mid to late October. Put the prepared nutrient soil (the kind used for vegetable seedlings will do) into trays or nutrient pots, then arrange them on the seedling bed, press a small hole with a finger and sow, one seed per pot. After sowing, cover with soil, water, and cover with film. Before sowing, it is best to mix well-rotted manure or farmyard manure into the seedling bed.

Papaya Planting Methods and Precautions

I. Planting methods:

1. Seedling management: Seedlings usually emerge about 10 days after sowing. After emergence, the soil must be kept constantly moist, but waterlogging should be avoided. When the seedlings have grown 2-3 true leaves, water should be controlled appropriately. When 4 leaves have emerged, topdressing can be carried out, once every 15 days.

2. Field planting: Generally, field planting can be done in early to mid-February. Because the papaya canopy is large, wide-row close planting can generally be adopted, with a plant spacing of 1.5 m × 2.5 m. For field planting, deep holes should be dug, generally 60 cm in diameter and 40 cm deep. When planting, try not to loosen the pot soil when removing the nutrient pot, so as not to damage the roots. Finally, water with the settling water and cover with film.

II. Precautions:

As the temperature rises, pay attention to removing the film and ventilating, so as not to burn the seedlings. After May 1st, the film can be completely removed. As the plants gradually grow, the amount of fertilizer applied must gradually increase. Start applying heavy fertilizer at the bud stage, and apply heavy fertilizer once every month during the 6-10 months of fruit development. With strengthened fertilizer management, flowering and fruiting can occur in mid-June.

Papaya Field Management

1. Cultivation and weeding: After the plants survive field planting, carry out cultivation and weeding twice a year in spring and autumn together with fertilization, loosen the soil with a hoe and remove all weeds. When loosening the soil in winter, earth up the soil to help prevent freezing damage.

2. Topdressing: Apply topdressing once before flowering in spring. First open a ring ditch around the tree, and apply about 5 kg each of burnt mud ash and farmyard manure, or about 10 kg of human excrement and urine per plant, to promote growth and benefit flowering and fruiting.

3. Pruning: Pruning has a great influence on the flowering and fruiting of papaya, and is best carried out from December to March of the following year. Adult trees are pruned once a year, cutting off diseased branches, dead branches, aging branches and overly dense young branches, so that the tree shape remains hollow inside and round outside, to favor more flowering and more fruiting. For old plants that have already reached more than 10 years of age and whose vigor has begun to decline, renewal should be carried out. Before the freeze, cut off all the aboveground parts and let the old roots grow seedlings, which can be cultivated into new plants.

Common Diseases and Pests of Papaya and Their Control

1. Leaf blight: Causes serious damage from July to September, harming the leaves. Control method: clean the field in winter; spray with 1:1:100 Bordeaux mixture in the early stage of the disease.

2. Peach fruit moth: The larvae bore into and eat the fruit. Control method: clean the field in winter; spray with a 3000-fold dilution of 2.5% deltamethrin in the early larval hatching stage.

3. Citrus longhorned beetle: The larvae bore into and eat the branches and trunk. Control method: manual capture and killing; plug cotton dipped in 80% dichlorvos emulsifiable concentrate into the insect holes; release Sclerodermus guani parasitoid wasps.

When planting papaya, be sure to pay attention to seed selection, then carry out seed sprouting treatment, and then choose a suitable time for planting. After planting, management also needs to be strengthened. Timely weeding, pruning and pest and disease control are all essential conditions for ensuring its growth.
