The most effective way to grow onions is to plant onion sets. An onion set is a small bulb, to 1 inch in diameter. Onion sets are produced under conditions that rapidly produce a small bulb which, when planted, will grow a larger bulb. You can buy onion sets at the local plant centre.
Onions can handle some frost and, in general, do not mind the cool and wet weather of spring. They prefer a soil that is rich and that drains well.
You can plant onion sets from two to four weeks before the last frost. Buy bulbs that are less than ¾ inches (19 mm) in diameter.
Space the onion sets approximately 4-6" (10-15 cm) apart, depending on the size of the mature bulb. Make sure that you gently press the bulbs into the soil about an inch (2.5 cm) deep and make sure to plant them so that their pointed tips just break the surface.
