How to transplant onion seedlings?

Onions are grown in all parts of my country and can be sown directly or transplanted. Transplanting onion seedlings can increase their survival rate and yield, but attention should be paid to the time and method of transplanting. So how to transplant onion seedlings? Let’s take a look with the editor below.

1. Choose the soil

Onions prefer fertile, loose and well-drained soil. Before transplanting, if the soil texture is poor, you can improve the soil by adding an appropriate amount of organic fertilizer or compound fertilizer to improve the soil fertility and air permeability. Remove weeds and rocks from the soil to avoid affecting the growth of the onion seedlings.

2. Transplanting time

The best time to transplant onion seedlings is usually in spring (April to May) or autumn (late October to mid-November), when the temperatures are moderate, which is conducive to the growth and rooting of onion seedlings. In areas where the winter temperature is above -7°C, it is best to transplant about 30 to 40 days before freezing. In areas where the temperature drops below -7℃ in winter, seedlings can be grown in greenhouses or greenhouses in March and onion seedlings can be transplanted from April to May.

3. Choose onion seedlings

Select seedlings with dark green leaves, thick stems and well-developed root systems for transplanting. Such onion seedlings have strong vitality and are easier to adapt to the new environment after transplanting. Avoid choosing seedlings with yellow leaves, thin stems or damaged roots, as these seedlings have a low survival rate after transplanting.

4. Remove the seedlings

Before transplanting, water the soil thoroughly to make it loose and easy to dig and transplant. Use a spade to carefully dig out the onion seedling, trying to keep the roots intact.

5. Planting

Determine the spacing between plants and rows for transplanting according to the onion variety and soil fertility. Generally speaking, the appropriate plant spacing is between 10 and 15 cm, and the row spacing is between 16 and 18 cm. The transplanting depth should be appropriate, generally controlled between 2 and 3 centimeters, to ensure that the roots are completely buried in the soil, but the stems should not be buried too deep to avoid affecting the growth and ventilation of the leaves. When transplanting, the seedlings should be vertical and not tilted.

6. Watering

Water in time after transplanting to ensure that the roots of the onion seedlings are closely integrated with the soil and promote root growth. Water the plants within 3 to 5 days after transplanting to promote survival. After that, water frequently based on weather and soil moisture, keeping the soil moist but not too wet.

The above is an introduction to how to transplant onion seedlings. After transplanting, the onion seedlings should be checked in time and the missing places should be replanted to avoid affecting the overall yield and quality. Weeding should also be done regularly to prevent weeds from competing with the onion seedlings for nutrients and light.
