One of the oldest known cultivated plants, onions are a staple in kitchens around the world, adding flavor to soups, sauces, stews, salads, salsas, and so much more. Known in the plant world as allium cepa, the onion crop is as diverse as it is delicious, with globe-shaped types you see at the supermarket, more rare heirloom varieties, and mild green onions — and the list could go on.
The beauty of growing onions, though, is that no matter what type you’re looking to cultivate in your garden, onions are hardy — they don’t mind a bit of early spring frost — and are consistent in growing requirements, which includes a lot of sunlight and well-drained, nutrient-rich soil.
In this guide, we’ll cover all the basics of how to grow onions, tips for tending to your onions as they grow, plus how to harvest onions and store them.
