Onions are easy to grow and can be planted from sets, plants or seeds. The size of the onion’s bulb is determined by length of growing season, so if you have a short growing season get sets or transplants.  

How Do I Grow Onions?

When you start your onions from seed begin in late winter.  Sprinkle twenty seeds into cups of vermiculite 8-12 weeks before last spring frost and keep the seeds warm at 70 F until they have sprouted.  Once the seedlings have begun to sprout, about 5 days later, move them to full sun and place them in seedling trays.  

Four weeks before the last spring frost, transplant your onion seedlings into their containers.  Shake most of the vermiculite from your plants then gather them in bunches.  With a pair of scissors but off the tops and roots of the plant so it’s balanced in terms of weight on either side.  Once the plants are prepared, make four holes per square foot and place your plant into each. Firm up the soil and water your new onions.

If you decided to purchase your onions by mail order, or from sets they may look dead upon seeing them for the first time, but they will perk up as soon as you get them in the ground.

Harvesting

Harvest your onions by pulling them for fresh use as you need them. Onions with thick green stems don’t do well in storage, so you’ll need to use them right away. For onions that do store well, harvest them when the tops have fallen off and knock over any upright stalks with a rake.  Then pull your onions 1-2 days later and let them dry on the ground.

When your onions are dry, braid the tops and hang in a cool dry place, or clip off the tops and store them in either a mesh bag or slat-sided boxes.

Preparing and using

Onions are easy to grow and almost necessary in the kitchen! They will store for months if kept in a dark, cool and dry place. Use them raw in your dips and salads or add them to whatever you're cooking for a nice flavour. Try different varieties to see which flavour you like the best.
