Planting time: Onions can be planted in March-April of each spring or during the period when the temperature continuously exceeds 6 degrees. Soil preparation: Soil preparation with sandy soil, pastoral soil and humus soil. Burying seeds: plant onion seeds in the soil with a spacing of 10 cm. Post-management: regularly eradicate weeds, water once a week and apply nitrogen fertilizer once a month.

How to plant onions 1, planting time

Onions can be planted in March-April every spring, or when the temperature is higher than 6 degrees continuously. At this time, the environment is suitable for the growth of onion stems and leaves, but it is not suitable for planting onions every winter. At this time, the onions planted in spring will consume all the stored nutrients, which is not conducive to the growth of bulbs.

2. Soil preparation

Onions are suitable for growing in loose and breathable soil with rich organic matter. In the process of planting, sandy soil, pastoral soil and humus soil can be mixed for soil preparation. In order to make the soil weakly acidic or alkaline, lime should be added to adjust the pH value.

Step 3 plant seeds

Select well-grown onion seeds, plant them in the field with the spacing of 10 cm, and then cover them with thin soil, and the buried depth should not exceed 2.5 cm, so as not to affect the growth of bulbs. After planting, step on the soil surface with your feet to improve the survival rate of onions.

4, post-management

After onion planting is completed, weeds in the field should be eradicated regularly to reduce the consumption of nutrients. Moreover, it should be watered once a week to moisten the soil layer of 2.5 cm, which is beneficial to the growth of seedlings. Nitrogen fertilizer should be applied every other month to allow plants to absorb enough nutrients.
