Discover the Secrets to Growing Alliums: Your Ultimate Guide to Onion Cultivation
Cooking with onions has always been a delight in our kitchen, and recently, my family decided to take the plunge into growing our own. This journey began with purchasing onion starts online, which yielded successful results, but after a little research, we decided to try starting our seeds from scratch, and what a game changer that has been!
In just a couple of years, we went from a small family garden to harvesting a catchy number of 1,000 onions this past season! If you’re a beginner, fear not—onions are not as finicky to grow as some might lead you to believe. With a dash of nitrogen-rich soil, a sprinkle of sunshine, and consistent watering, you can achieve your onion-growing aspirations!
Onions, glorious onions—growing in the home garden.
Starting Your Onion Adventure from Seed
While you can always purchase onion starts, starting from seeds opens up a world of options! Not only can you choose from a range of varieties, but you also get the satisfaction of nurturing them from the very beginning. In regions with harsher winters like mine, starting seeds indoors around the first of January means a flourishing harvest come late June. However, if you’re in a warmer climate, summer sowing is the way to go, allowing for a fall planting and a sweet spring yield.
To embark on your seed-starting quest, gather your moistened seed-starting soil and containers with drainage holes. Fill the containers, ensuring a gentle pack, and then spread your onion seeds in rows or broadcast them randomly—onions can be nestled closely together unlike many other garden plants. A light covering of soil followed by a gentle misting will keep your seeds moist. Be sure to cover your containers with plastic bags or lids, or simply mist daily until germination graces you!
The Art of Planting Onion Bulbs
Once your seedlings stand tall and proud, it’s time to transition to the outdoor garden. In my zone, the sweet spot for planting bulbs is early March, or even February if you have a high tunnel! Arrange your onions six inches apart in rows, leaving six to nine inches in between each row, so they have room to grow wild and free. Remember to shower them with water generously after planting!
Nitrogen is the magical elixir for onions, nourishing them as they grow. If your soil lacks this essential nutrient, consider enriching it with compost to ensure your bulbs don’t just grow—they thrive!

Knowing When to Harvest
As the ascent to harvest day approaches, keep an eye on the tops of your onions. When they start wilting and falling over, it’s time to scale down on watering. Once half of your crop has bowed down, give the rest a gentle push. Harvesting should happen when the outer tops have browned—a clear sign that your labor has paid off!
Storing Your Bountiful Harvest
Once you’ve gathered your crop, the next step is curing them for long-term storage. This involves letting the onions sit in a breathable area for several weeks, allowing the tops to dry naturally. Once dried, snip the tops off around 1 to 2 inches above each bulb and place them in netted bags. A cool, dry space is ideal for storage, and remember that different onion cultivars have different storage longevity—monitor them closely to enjoy their flavor for months to come!
Proper storage extends the shelf life of your onions.
Final Thoughts
As someone who has turned my gardening passion into a full-blown onion-growing venture, I encourage everyone to give it a go. The rewards are endless—from their versatile use in your favorite dishes to the sheer joy of harvesting what you’ve sown. My trips to the grocery store have become less frequent as I’m now reaping the benefits of homegrown goodness. So grab those seeds, roll up your sleeves, and transform your culinary experience with an abundant supply of delicious onions!
