How to Plant Green Onions from Bulb: Helpful Products for Easy Regrowth (2026)

The Liliana's Garden Bunching Onion Mix is a curated collection of eight different scallion varieties, all packed into one convenient seed packet. Designed for both new and experienced gardeners, this mix includes types like Ishikura Improved (long white stalks), Apache (red with a sharp bite), and Heshiko (rich heirloom flavor). It's ideal for anyone who wants a continuous supply of green onions for garnishing, cooking, or fresh eating, without having to buy multiple packets of different varieties.

One standout feature is the diversity of colors and flavors. You get red, white, and green stems, so your garden and plate look as interesting as they taste. The claim of harvest in 50 days holds up well in most home gardens, especially when seeds are sown in fertile, well-drained soil with regular watering. Many users report that the seeds sprout quickly and abundantly, and that the plants regrow after cutting, extending the harvest season.

On the downside, a few customers experienced poor germination rates or weak seedlings. While the brand guarantees at least 85% germination, results can vary with temperature, soil quality, and watering consistency. There have also been occasional delays in shipping and some packets arriving with fewer seeds than advertised, though these instances seem infrequent. The product is also not suited for indoor growing unless you have strong grow lights and a controlled environment, as it prefers outdoor conditions.

Overall, this bunching onion mix offers excellent value for the price, especially for gardeners who appreciate variety and quick turnaround. The heirloom, non-GMO seeds and USA origin add to its appeal. If you follow the included growing guide and provide consistent moisture, you'll likely enjoy a steady supply of fresh scallions from spring through fall. Just be prepared for the possibility of variable germination, and order early to avoid any shipping delays.

You can harvest them young for salads or let them mature into full-size onions for storage. The ability to plant in garden beds, raised planters, or even containers indoors adds to their appeal.

In terms of build quality, the bulbs are generally healthy and firm upon arrival, though a small number of customers have received dried-out or papery bulbs. The packaging is recyclable and the sets are shipped year-round, which is convenient for planning your planting schedule. The brand's commitment to chemical-free growing and bee-friendly practices is a nice bonus for eco-conscious gardeners.

On the downside, some users experienced variable yields, and a few found that a portion of the bulbs didn't sprout. Additionally, the product cannot be shipped to Idaho or Washington. Overall, this onion set mix offers good value for the price, especially if you want a diverse harvest without buying multiple varieties separately. It's a solid choice for any home gardener looking to grow their own onions with minimal fuss.

The CaribbeanGarden Sweet Granex onion sets bring one of the most beloved sweet onion varieties straight to your home garden. These are intermediate day-length onions, meaning they perform well across a wide range of latitudes. Each pack contains between 40 and 70 bulbs, giving you plenty of starts for a generous harvest. The variety is closely related to the famous Candy onion but with better storage capabilities - a clear advantage if you want to enjoy your onions well into the fall.

What sets these onions apart is their super sweet, mild flavor. They lack the harsh bite of standard storage onions, which makes them perfect for eating raw in salads or on sandwiches. That sweetness also shines when caramelized or grilled, adding depth to burgers, pizzas, and soups. Because they store longer than other sweet types, you can gradually use them over several weeks without worrying about spoilage.

Growing these onion sets is straightforward. Simply plant the bulbs pointy side up in sandy, well-drained soil about an inch deep and four inches apart. They thrive in full sun and need consistent moisture, especially during bulb formation. The plants are hardy to USDA zone 4, so they can handle colder springs and early frosts better than many other sweet onion varieties. You can expect good-sized, round bulbs with a bright yellow skin.

One minor drawback is that not every bulb may sprout - a common issue with onion sets. To maximize your yield, choose firm, dry bulbs and avoid planting in soggy ground. Also, if your soil is heavy clay, consider amending it with sand or organic matter to improve drainage. The pack size claims 40-70 bulbs, but the standard unit count is 40; larger packs may yield more, but it's worth checking the listing details.

Overall, these onion sets are an excellent choice for home gardeners who want a sweet, versatile onion that's easy to grow and stores well. Whether you're a beginner or an experienced grower, the CaribbeanGarden Sweet Granex delivers reliable results and delicious flavor straight from your backyard.

The Sow Right Seeds Tokyo Long White Bunching Onion seeds are a fantastic choice for anyone looking to grow fresh green onions at home. This Japanese heirloom variety is known for its mild, sweet flavor and tender white flesh, making it a versatile ingredient in everything from omelets to stir-fries. Whether you are a beginner gardener or a seasoned pro, these seeds are designed to deliver a reliable harvest with minimal fuss.

One of the standout features is the high germination rate. A verified buyer tested these seeds in winter conditions using a moist paper towel and seed mat, and nearly all seeds sprouted within days. This indicates fresh, clean seeds with no signs of mold or fungus. The packet is stamped for 2026, so you can expect strong viability. The plants grow 14-24 inches tall, which is impressive for green onions, and they mature in 65-95 days, giving you a steady supply from summer through fall.

This means you are getting a sustainable product that is safe for your family and the environment. The packet includes clear planting instructions, and the brand offers a germination guarantee if you encounter any issues. The only potential drawback is that there is only one customer review so far, so long-term performance data is limited. However, the available evidence points to a high-quality product.

Overall, these seeds are an excellent value for home gardeners. They are easy to grow, productive, and deliver a delicious, mild onion flavor that elevates any dish. If you want a reliable bunching onion that thrives in a range of climates, this is a solid pick.

The Sow Right Seeds Heshiko Japanese Bunching Green Onion is an heirloom, non-GMO variety that brings a mild onion flavor to your kitchen garden. It is ideal for home cooks who want fresh green onions on demand, whether you have a backyard plot or just a sunny windowsill. This bunching onion grows upright and does not form a bulb, so you can keep harvesting the green stems as needed.

One standout feature is its cold hardiness. Unlike many onions, Heshiko can withstand cooler temperatures and continues producing through fall. The seeds germinate quickly in warm soil, often within 10 to 14 days, and many users report sprouts in under a week. The full-grown plants reach 10 to 14 inches tall, and the mild flavor works perfectly in stir-fries, soups, and salads without overpowering other ingredients.

The seeds come in a large, colorful packet with about 250 seeds, more than enough for multiple plantings. The instructions are printed on the packet and are easy to follow, even for beginners. Sow Right Seeds operates on solar power and pledges to sell only safe, non-GMO seeds. This commitment adds to the appeal for environmentally conscious gardeners.

That said, germination success depends on soil temperature staying between 68 and 75 degrees F. A few customers had poor results, likely because they planted in cooler soil or did not keep the seeds evenly moist. Starting them indoors under a grow light or in a warm spot can help. Overall, when conditions are right, these seeds perform reliably well.

Verdict: The Sow Right Seeds Heshiko Japanese Bunching Green Onion is a solid choice for anyone wanting an easy-to-grow, mild-flavored green onion that keeps on giving. With quick germination, cold tolerance, and a generous seed count, it offers great value for both new and experienced gardeners. Just pay attention to soil temperature and moisture for the best results.

In terms of performance, customer reviews are overwhelmingly positive, with many praising how quickly and reliably the onions regrow.

The Simply Seed Sweet Yellow Onion Bulbs are a popular choice for home gardeners who want a reliable, high-yielding onion variety. This long-day onion is bred for northern and southern climates alike, forming bulbs when daylight lasts 8-10 hours. It's non-GMO, naturally grown, and raised in America - a solid option for anyone who values seed integrity and straightforward gardening.

In terms of performance, these onions consistently produce heavy bulbs that can reach up to 1 pound each, with a sweet, mild flavor that works great fresh or cooked. Many reviewers report good germination rates and vigorous growth, especially when planted in well-drained soil with full sun. The storage life is a standout feature: properly cured bulbs can keep for 6-8 months, giving you homegrown onions well into winter. Some users note that not every bulb hits the 1-pound mark, but overall yields are substantial for a standard garden pack.

The bulbs arrive as sets (small onion bulbs) ready for planting. They typically come in a bag with 60-80 pieces. Quality control can be a minor issue - a few customers mention finding mold or rot from moisture during shipping. It's wise to open the package upon arrival, remove any soft or damaged bulbs, and plant the healthy ones promptly. The sets are generally firm and fresh, with many already showing green tips when received, which signals they're ready to grow.

Drawbacks are limited but worth noting. Besides the occasional size discrepancy, germination can be uneven if the soil is too wet or compacted. Also, the long-day requirement means they may not perform as well in extreme southern areas with short summer days. But for most of the U.S., this variety is a dependable performer. The price is reasonable for the quantity, and the seller offers a guarantee on growth results.

Overall, the Simply Seed Sweet Yellow Onion Bulbs are a solid buy for any gardener who wants a sweet, storing onion that delivers consistent results.
