Grow Amazing Alliums: How to Plant Onion Bulbs and Seeds

Discover how to cultivate a year’s worth of flavorful onions right in your garden!

Growing your own onions can transform your culinary adventures. The journey begins with either purchasing onion starts or going the more rewarding route of starting from seed. Growing from seed offers a wider variety and the chance to nurture your plants right from the beginning.

Starting Onions from Seed

For those new to gardening, starting onions from seed might seem daunting. However, it’s quite manageable once you understand the process. In colder climates, sowing seeds needs to commence as early as January to ensure a bountiful harvest in late spring. Conversely, in warmer zones, seeding can occur as late as summer, gearing up for a fall harvest.

Start by filling containers with moist seed-starting soil, ensuring each has proper drainage. You can broadcast seeds or arrange them in rows, planting them close together. Cover with a thin layer of soil and lightly mist with water to create a humid environment—seeds prefer this sprouting method. Using plastic bags can help maintain moisture until they sprout.

Planting onion seeds in a cozy container setup can boost your yield.

How to Plant Onion Seeds

Timing is everything when planting onions. In many regions, March marks the ideal planting period; however, if you’re utilizing a high tunnel, you might get away with planting in February. Remember: the sooner your onions get in the ground, the healthier they’ll become!

Onions are resilient and can withstand frost, so don’t fear planting early. When ready to transplant, carefully separate the seedlings and place them in the ground with their tops exposed and roots just touching the soil. Space them about six inches apart in rows—keeping the rows six to nine inches apart will ensure good air circulation. Rich, nitrogen-based soil is essential for their growth, so consider enriching your garden bed ahead of time.

As your onions start bulbing, which is when the roots swell, it’s crucial to stop fertilizing. Continued thorough watering is key, but loosening the soil around the bulbs is not necessary; they will naturally push the earth away as they grow.

Harvesting and Storing Options

You’ll know your onions are nearing harvest when the tops begin to fall over. At this stage, cease watering. Once about half the tops have laid down, bend the remaining tops to assist with drying. Harvest the bulbs once the outer skins appear brown and papery.

Be gentle when brushing off soil; retaining the outer skin is essential for storage. After allowing the tops to dry completely, cut them off about one to two inches above the bulb and store them in netted bags or cool, dark places. Each onion cultivar might have a different shelf life, so monitor them closely. Smaller or damaged bulbs should be used promptly, whether through cooking or preserving methods like freezing, dehydrating, or pickling.

Harvesting onions at the right time ensures the best flavor and longevity.
