How to Grow Onions

Onions can be grown from seed or sets (small bulbs). Sets are more costly, and there is a smaller range of cultivars available, but they are quick, reliable and a good choice for beginners.

Lift and Dry

Onions are ready for harvesting in midsummer, when the leaves turn yellow and fold over. Lift them and place in a cool, airy place to dry out for a couple of weeks. Use any with thick necks right away, and store the others for later.
