3. Which is the best month to sow onion seeds?

Onion seeds can be planted directly in the garden bed. However, when growing onion seed, some people prefer to start them indoors. This can be done in late autumn. The best time for planting onion seeds outdoors is in spring, as soon as the soil can be worked in your area.

4. How long does it take to grow onion from seed?

Onions are cool-season crops that require 90 days or more to reach maturity. Because of this long growing season requirement and their preference for cooler weather, planting onion seeds directly into the garden in the spring makes it difficult for the bulbs to reach a good size before warm temperatures arrive.
