In this series I’m compiling the quick and dirty info on growing specific vegetables. Just the basics. No fluff, no frills. When you’re sitting down in the late Winter, surrounded by seed catalogs, and your garden plan in front of you, you want a quick reference. How far apart can you plant? What pH do they need? How much water? What vegetables can you plant next to others? Which should you avoid?
Onions are a staple in any American kitchen. I have fond memories of my grandmother’s kitchen. The smell of onion skin, garlic, and banana nut bread still bring me back to playing on the kitchen floor while she cooked.
They are incredibly easy to grow, needing only occasional weeding. They can be started from seed or you can buy onion “sets” or small, already started onions.
Starting onions from seed gives you the opportunity to grow more varieties of onions, whereas the “sets” you can generally find in feed stores are hybrids. To start them from seed, dig a shallow trench (1/4 inch deep) and sow them in a long line. Keep them warm and moist (but not soggy!). It may take a few weeks for them to sprout. Be patient! Once they’ve begun to sprout and grow tall enough to fall over, cut them back a few inches. These onion sprout trimmings are a great addition to soups, salads and sandwiches.
One the root balls are about quarter sized, you can harden them off and transplant them outside. Check out my post on how to start plants from seed for tips on transplanting success.
If starting the onions from “sets”, plant them in bunches of four. The onions will grow away from each other, but be easier to water and weed.
If you’re brave enough to start onions from seed, check out Seeds for Generations. They’re a small, family-run seed business that boast great quality seeds.

Saving The Seeds
To harvest onion seeds, you need to leave the plant in the ground for two years. Onions only go to seed every two years. The plant will form flowers and then seed heads. Once the flower starts to dry, harvest it and dry it out completely. Then separate the seed from the rest of the flower.
