How and when to plant onions

Onion planting time and month

Onions can be planted all year round, and the best time to plant them is from August to September. The temperature at this time is between 20-25 degrees, which is conducive to the germination and growth of onions. The onions planted at this time are high-yield and high-quality.

Onions can be sown in spring from February to March. After sowing, water and fertilize in time to promote vegetative growth, control reproductive growth, and reduce immature bolting. Water for the first time when the plants turn green, and apply top dressing in combination with the greening water.

Onions can be sown in June-August and spread evenly. The amount of seeds used depends on the purpose of cultivation. If the temperature is high and the light intensity is high, a shade net can be used. In addition, an insect-proof net is also needed to achieve the goal of using less or no pesticides.

Onions are generally planted from July to September, but are harvested in late May to early June. After the bed surface is leveled, you can wet the soil and then spread the seeds evenly. After sowing, cover with 0.8 cm of nutrient soil to ensure that the seedlings are all grown at once. You can also sow them after germination.

How to plant onions

1. Watering: Onions will enter the seedling growth stage 15-20 days after planting. Do not water too much at this time, otherwise the ground temperature will be lowered, causing the seedlings to grow slowly. At the same time, the new roots of the newly planted seedlings have not yet sprouted, and the soil cannot be dry. You can water them in small amounts multiple times to promote the rapid rooting and survival of the seedlings.

2. Fertilization: Onions are fertilizer-loving plants. Fertilizers containing nitrogen, phosphorus and potassium should be applied in time during the growth period. Do not apply too much nitrogen fertilizer. Water the spring-sown onion seedlings in time before and after they emerge from the soil to keep the soil slightly moist. Appropriate amounts of water and fertilizer should be added during the peak leaf growth period and bulb expansion period.

3. Loosening the soil: Planting onions in loose soil is conducive to the development of the root system and the expansion of the bulb. Generally, the soil can be loosened 3 to 4 times during the seedling stage, which can be done after watering, and 2 to 3 times during the stem and leaf growth period. The depth of inter-cultivation should be about 3 cm.
