Then choose an old fruit to get seeds for seed germination.

In addition to seeding, people can also buy grafted plants or plant branches. However, it is necessary to choose good plants, no pests and diseases, and the leaves are not crushed.

If the soil is salty, the water is often high and waterlogged, the rootstock of the bowl should be grafted. Thus, the plant will adapt well to alkaline, drought, and waterlogged soils. At the same time, this method also helps the tree to grow well, give more fruit, and take longer to collect fruit.

The planting hole needs to be loosened, forming a mound of 40-60cm wide and 25-30cm high.

Prepare the soil 5-7 days in advance to have time to dry and kill pests. At the same time, apply lime powder and fertilize with 2 – 3 kg manure + 200g phosphate fertilizer per hole to improve and add nutrients to the soil.

  1. How to grow soursop

Put the potted rootstock in the lake, then bury the soil around it, then make sure it’s soaked with water.

For nursery plants with pots, gently remove the pot, place in the center of the base, fill the surrounding soil to form a 10cm high mound. Each year, tissue accretion will be carried out according to the radius of the foliage.

Taking care of the soursop tree

  1. Fertilization

Use: 10 – 15 kg of rotting manure + 0.5 kg of fused phosphate + 0.5 kg of powdered lime to fertilize each planting hole.

People can use synthetic fertilizer NPK 10 – 10 – 10 or NPK 16 – 16 – 8 + 10kg per year of rotting manure to fertilize plants for 3 years. In the following years, each year, add 0.3kg of NPK synthetic fertilizer. Fertilizing the 9th year stops at that level, does not increase anymore.

When fertilizing, farmers divide it into 2-3 times: After harvesting (at the end of the rainy season) and when the tree is growing fruit (at the beginning and at the end of the rainy season). In addition, at the beginning of the rainy season, people add 1kg of fused phosphate fertilizer to each tree. At the end of the rainy season, apply 0.2kg of potassium/plant.

  1. Sprinklers

Although custard apple lives at high temperatures, it has good drought tolerance, but in order to produce a lot of fruit, it needs to be watered with enough water. If planted at the beginning of the rainy season, people do not need to water too much. In the dry season, water once a day when the tree has not yet produced fruit.

Note that when the tree is carrying young fruit, it needs to be watered enough, if there is a lack of water, the tree will lose leaves and fruit, small fruit. Time of fruiting, if in the dry season, water 2-3 times/week.

This disease is caused by fungi and nematodes. Diseased trees will quickly weaken, yellow leaves, drop leaves, trees will die gradually. The roots are necrotic. This disease attacks from the roots to the base causing the tree to die from the inside out. With trees that have died or fallen fruit due to disease, people should dig anise and bury them.

Anthracnose is caused by the fungus Colletotrichum gloeosporioides. Infected plants will have soft rot on the branches, which will spread to the fruit. This disease is especially contagious during the rainy season.

To prevent diseases, people need to prune trees to create airiness for good photosynthesis. Dead trees and fallen fruit should be destroyed to avoid spreading. Can be buried or burned.

  • Aphids, mealybugs, leaf borers

In addition, there are some types of planthoppers, aphids, and other pests that suck sap from the fruit, affecting yield and creating opportunities for pathogens to develop.
