A detailed guide to growing onions from seed, from sowing to daily care

Onion is a common vegetable in our daily life, with high nutritional value. Onions are always propagated by sowing when grown, so how should onion seeds be planted? Let's take a look at the detailed introduction.

1. Seed selection

When planting, you must first select suitable seeds for planting. Generally, seeds from the current year should be chosen, as this can increase the sowing germination rate. If old seeds are chosen, the lifespan of the seeds is limited, old seeds have lower vigor, and the longer they are stored, the lower the germination rate becomes, making it difficult for them to sprout after planting and causing losses to farmers. At the same time, also check whether the seeds show signs of pests or diseases and whether their surface color is bright and fresh.

2. Sowing time

Sowing time is extremely critical, as it affects the yield and quality of onions, so sowing time must be taken seriously. Although onions can be grown all year round, they prefer a cool environment and have strong cold tolerance; at high temperatures above 26 degrees they enter a dormant state and stop growing. Therefore, it is recommended to plant from July to September, when the temperature is about 20-25 degrees. After sowing, onions will grow extremely fast, which can improve yield and quality.

3. Seed soaking to speed up sprouting

To increase the germination rate of the seeds, sprouting should be promoted before sowing, which not only improves the seed germination rate but also makes the seedlings grow uniformly. First, soak the seeds in warm water at about 50 degrees for 4 hours so they absorb water fully, then rub and wash off the waxy layer on their surface, and after drying they are ready for sowing.

4. Sowing method

The soil for sowing onions must be fertile, loose and well aerated. You can also mix garden soil with decomposed farmyard manure to create the needed fertile, well-aerated soil. Then water the soil thoroughly, keep a layer of fine soil spread on top, and simply scatter the seeds over the soil. After sowing, cover with plastic film and keep the temperature at about 20 degrees. After about a week the seeds will sprout. Do a good job of seedling-stage management, thinning and filling in seedlings in time, to promote seedling growth.
