In the southern regions, where winters are not so harsh, onions can be planted quite early. As soon as the average daily temperature stabilizes within 5-7 degrees Celsius, and the soil thaws and becomes suitable for cultivation, you can start planting. This usually happens in mid-March or early April. In this region, it is important not to delay, as excessive heat can cause the plants to shoot.
In the central part of the country, planting dates are shifted closer to mid-April. Spring here can be changeable, so it is worth focusing on the condition of the soil. If the ground is still cold and sticky, it is worth waiting a few days until it dries well. It is important not to rush, but also not to wait too long, as late planting can affect the harvest. Moist spring soil promotes rapid rooting, so the onion develops well and forms a strong root system.

In the northern regions, planting takes place later, approximately at the end of April or even at the beginning of May. Spring here is long, and the soil warms up more slowly. If you plant onions too early, there is a risk of their rotting or slowing down their growth. It is optimal to wait until the top layer of the earth warms up and stops being too wet. Some gardeners additionally cover the beds with agrofibre to speed up the warming process and protect young plants from possible night frosts.
It is important to remember that planting dates can be adjusted depending on the weather conditions of a particular year. If spring is early, work can be started earlier, but if it is long and cold, it is better to wait so as not to risk the harvest. In addition to temperature, it is worth considering the varietal characteristics. Early varieties are planted in the first half of the season, and late ones - a little later. The main thing is to follow the natural rhythm and choose the best moment to work on the beds.
