Can durian be grown in the north? A detailed explanation of the growing climate conditions

SummaryDurian is not suitable for growing in the north. Growing durian in the northern climate makes it very difficult to survive, and it will not bear fruit. Durian is a tropical crop, and generally only in areas with no frost throughout the year, annual rainfall of 1000 mm, and a multi-year average low temperature above 0°C can it bear fruit normally.

1. Can durian be grown in the north

Durian is a crop that grows in the tropics. The tree is 15-20 m tall, with a relatively obvious trunk and fragile branches that are easily damaged by strong winds. It generally can grow normally only in areas with a multi-year average low temperature above 0°C, basically no frost throughout the year, an accumulated temperature of 7000-7500°C or more at ≥10°C, and annual rainfall of 1000 mm. Therefore, growing durian in the north is very difficult to succeed at.

2. Durian growing methods

1. Sowing

Durian is generally sown in spring. The durian seeds are inside the flesh. You can take them out and soak them in clean water. Under relatively suitable temperatures, wait 24 hours and you will see the seed coat split. Then continue soaking until the white inner kernel comes out, sow at a plant spacing and row spacing of 20 cm, then cover with a small amount of shallow soil. During this period, keep the soil moisture at about 30%, and before long it will sprout and emerge.

2. Raising seedlings

During the growth of the seedlings, weed and shallow-cultivate in time, clear the weeds in the field to avoid weeds robbing the seedlings of nutrients for growth. Shallow cultivation can speed up seed germination and emergence. When shallow-cultivating and weeding, you can water and fertilize to promote rapid seedling growth. In addition to the sowing and seedling-raising method, you can also use air layering propagation from excellent mother plants. This makes it easier to take root and form new seedlings, and from propagation to becoming a seedling takes only 2-3 months.

3. Transplanting and field planting

When the seedlings grow to 40-50 cm, they can be planted. When planting, first plow the planting soil, then apply organic fertilizer, farmyard manure, and lime as base fertilizer. The amount of base fertilizer applied can be determined according to the growing environment and scale. Generally, planting can be done throughout the year. When lifting the seedlings, water the soil thoroughly, then dig out the root system with soil. Be careful not to damage the root system, to avoid affecting the survival rate of planting. Planting can be done at a plant spacing of 3 m and a row spacing of 5 m.

4. Field management

(1) After durian is given sufficient base fertilizer, it still needs to be fertilized 2-3 times each year, respectively at the flower bud emergence stage, the fruit expansion stage, and before harvest. The types of fertilizer applied also differ among these three periods. During this time, mainly water-soluble fertilizer is applied. The water-soluble fertilizer can be diluted with water and applied by drip irrigation, sprinkler irrigation, or root irrigation.

(2) This method is both convenient and quick, and it will not harm the durian root system. It helps improve fertilizer use efficiency. Durian has relatively strong sprouting ability, and under conditions of sufficient water and fertilizer, it is prone to excessive vegetative growth. Therefore, timely shaping and pruning are needed to keep the plant in a beautiful tree shape, increase its air permeability, and improve quality and yield.

5. Harvesting

The ripening period of durian is in November, February, and June-August. When the fruit color turns orange-yellow or orange-red, it is ripe, and then it can be harvested. After harvesting, it needs to be stored for about 7 days, and it can be eaten only after the flesh becomes soft.
