Onions are a cold-season fall or spring crop, easy to grow because of their hardiness. Whether you start your onions from seed, sets, or seedlings, there are some tricks of the trade that make the difference between a great crop and a disappointing one. We’ll show you how to grow onions so perfect they could make you weep!
Onions can be planted in either the spring or fall. Onion plants grow well in raised beds or raised rows at least 4 inches high. We usually plant a mix of white, yellow, and red onions.
Should I Grow Onions from Seed or from Sets?
We prefer planting onion sets over starting them from seeds, simply because the sets establish quickly and are easier to plant. Onion sets are small onion bulbs that are sold specifically for gardening. Once planted, they develop into a full-size bulb after about 3½ months.
Also, onion sets can be planted without worry of frost damage and have a higher success rate than planting from onion seeds or transplants.
Of course, starting onions from seed is certainly doable, and may even be necessary in colder regions (Zone 5 and colder). If you’d prefer to try this method, check out our tips for growing onions from seed indoors.
