When to Plant Onions in Michigan: 2026 Guide for Spring and Fall Planting

KVITER's Vidalia Sweet Onion Seeds bring the famous Yellow Granex hybrid to your garden, offering a chance to grow those sweet, mild bulbs that make Vidalia onions so popular. This short-day variety is designed for southern growers, where fall planting lets the onions overwinter and develop into large, flavorful bulbs come spring. With 200+ organic, non-GMO seeds in the pack, you have plenty to work with, whether you start them indoors or direct-sow in your garden.

Real-world performance is a mixed bag based on customer feedback. Many reviewers praise the taste and ease of growth, noting the onions thrived in raised beds and even resisted pests. One happy gardener said the onions tasted great and grew easily with minimal critter trouble. However, others struggled with germination. A few reported that despite trying different methods, not a single seed sprouted, while another found that after two seasons, the bulbs never grew larger than a marble. This suggests that while the seeds are authentic, success may depend heavily on your planting conditions and timing.

Design and build quality are straightforward: these are tiny, uniform seeds in a standard packet, weighing just 0.176 ounces. The organic certification and non-GMO label are a plus for clean gardening. But be warned, the seeds are very small, so some reviewers recommend ordering more than 200 to ensure a full patch. The product care instructions are simple, requiring full sun, sandy soil, and moderate watering, but the short-day nature means you must plant in fall for the best results.

Drawbacks include inconsistent germination rates and the need for precise fall planting in southern zones. If you live in a colder climate or try spring planting, you might not get the large bulbs you expect. Still, for the price, these are a solid entry for anyone wanting to experiment with a classic onion variety. Just be ready to adjust your approach based on local conditions.

Final verdict: KVITER's Vidalia Sweet Onion Seeds are a good pick for southern gardeners who want sweet, homegrown onions, but they come with a learning curve. The organic, non-GMO seeds and generous count make them worth trying, but if you are new to onion growing, start with a small test batch to see how they perform in your soil.

The TomorrowSeeds Super Sweet Candy Onion Sets are a fantastic choice for home gardeners who want a reliable, mild-tasting onion. These Vidalia-type bulbs are intermediate day neutral, meaning they grow well in most U.S. regions without issues. Whether you're a seasoned grower or a beginner, these sets offer an easy entry into onion cultivation, with the promise of both green onions early on and full-sized bulbs for storage later.

One standout feature is the flavor: these onions are genuinely sweet and mild, perfect for fresh use in salads, sandwiches, or salsas. They also excel when grilled or caramelized, bringing out a rich, tender sweetness. Many customers note that the bulbs arrived in good condition and sprouted quickly, with high germination rates. The bulbs produce large, uniform rounds with golden-brown skin and crisp white flesh.

In terms of design and build quality, the product consists of small starter bulbs that are ready to plant. They are straightforward to handle, with no special preparation needed. However, packaging and shipping can be hit or miss. Some buyers reported receiving bulbs that were shriveled, rotten, or already sprouted, which impacted plantability. This seems to be a quality control issue, though most orders appear to be in fine shape.

Storage performance is a major plus. When cured properly, these onions can last for months without losing their texture or sweetness, a feature prized by those who like to grow their own pantry staples. The early maturity means you won't wait long for your first harvest, which adds to the appeal for impatient gardeners.

Overall, the TomorrowSeeds Super Sweet Candy Onion Sets deliver on flavor and ease of growth. While occasional quality issues with individual bulbs may occur, the majority of users are satisfied. This product is best for anyone wanting a dependable, sweet onion variety for fresh eating, cooking, and long-term storage. A solid choice for the 2026 growing season.

The 30 Yellow Granex Onion Plants bundle aims to bring the sweetness of famous Vidalia-style onions to your home garden. These short-day onions are known for their mild, non-pungent flavor and thin yellow skin. They're ideal for gardeners in USDA zones 7 and warmer, where they can be planted in early spring for a summer harvest. The plants are marketed as bolt resistant, which means less chance of flowers stunting bulb growth.

In terms of performance, the description promises a 100-day maturity and the ability to harvest green onions in just 30 days. Many customers have reported success with strong growth and good yields. However, a significant number of reviews point to poor condition upon arrival: plants arriving dried out, limp, or completely rotten. The 2.9-star average rating reflects this inconsistency. While some buyers loved their healthy transplants, others found up to 90% of the order unusable.

The build quality of the plants themselves is a gamble. When they arrive fresh, they are vigorous and easy to plant. But the packaging and shipping appear to cause issues, especially if delivery takes longer than expected. The seller offers a 100% guarantee, but getting a replacement may require extra effort. For the price, you're getting 30 bare-root starts, which is competitive, but only if they survive transit.

For potential buyers, the main drawback is the lack of reliability. If you have a garden that relies heavily on these onions, consider ordering early to account for possible replacements, or look for a more consistent nursery source. On the flip side, those who receive healthy plants often rave about the flavor and ease of growth. This is not a product for beginners who need guaranteed results.

Overall, the Yellow Granex onion plants promise excellent taste and good growing traits, but execution falls short due to poor handling and shipping. If you're willing to take a chance and can provide ideal growing conditions, you might be rewarded with a bumper crop of sweet onions. Otherwise, proceed with caution and check recent reviews before ordering.

If you are looking to grow your own onions at home, the CoolBeansNSprouts Red Onion Bulb Sets offer a straightforward and affordable way to get started. This package contains 100 red onion bulb sets, which are essentially small bulbs ready to plant in your garden or containers. The brand is upfront about one thing: they do not guarantee the size, shape, or form of the bulbs. That means you will receive a random assortment of sizes, but you will get the full count you paid for.

The standout feature here is the quantity. For the price, you get a hundred bulbs, which is enough to fill a decent-sized garden bed or several containers. Onions are a versatile crop; you can harvest them young as scallions or let them mature into full-sized bulbs. The planting instructions provided are clear: plant in spring or fall, bury the sets 1-2 inches deep with the pointy end up, and space them 2-6 inches apart. They need full sun and moderate watering, about an inch per week. If you want sweeter onions, you can water a bit more.

One thing to consider is the lack of reviews. With a rating of 3.9 but zero user feedback, it is hard to gauge real-world performance. The disclaimer about random sizes might be a concern if you are expecting uniform bulbs. However, for the price, it is a low-risk experiment for home gardeners. The bulbs are natural products, so some variation is normal. If you have sandy soil and a sunny spot, these should grow well.

In terms of design and build, these are just raw onion bulbs, so there is not much to say. They come in a simple bag. The key is to plant them correctly and provide the right conditions. The instructions mention that planting too deep can affect bulb development, so follow the guidelines.

Overall, the CoolBeansNSprouts Red Onion Bulb Sets are a solid value for gardeners who want to try growing onions from sets rather than seeds. The large quantity and clear planting advice make it beginner-friendly. Just keep in mind the variability in bulb sizes and the absence of customer reviews. If you are okay with that, these are a good buy for your home garden.

Many reviewers mention receiving over 100 bulbs in their order, offering excellent value for the price. The onions are suitable for both fresh eating and long-term storage, with the Yellow Stuttgarter variety known for its excellent keeping qualities.

In terms of quality, the bulbs are generally described as healthy and firm, though a few customers have noted some soft or moldy specimens. The packaging is compact and the sets arrive ready to plant. The color mix adds visual interest to garden beds, and the different flavors allow for culinary versatility from crisp red onions in salads to sweet whites in salsas.

One potential drawback is that the distribution of colors may not be perfectly equal, with some customers receiving more white and red onions than yellow. Additionally, while most bulbs sprout well, a small percentage may be too soft to use. However, the overall germination rate appears high based on feedback.

Overall, the TomorrowSeeds 3 Colors Mix Onion Sets are a reliable and cost-effective way to grow a diverse onion harvest.

It is designed for gardeners who want variety without having to buy multiple separate packs. Whether you have a small backyard patch or a dedicated raised bed, these bulbs are ready to go into the ground and start growing.

One of the standout features is the mix itself. Having three types of onions means you can enjoy different flavors and uses. White onions are great for fresh eating, yellow for all-purpose cooking, and red for salads and garnishes. The 100 count gives you enough to fill a decent area or share with friends. Users have noted that most bulbs are healthy and sprout reliably when planted in good conditions.

Planting is simple: just place the bulbs pointy side up in loose, well-draining soil and water regularly. The sets are small enough to fit in close spacing, making efficient use of garden space. Growth is steady, and within a season you can harvest full-sized bulbs. The brand is known for providing affordable seeds and sets for home growers, and this product continues that tradition.

There are a few things to keep in mind. Because the mix is random, you cannot control the ratio of colors. Some customers have reported receiving more of one type than expected. Also, the size of bulbs can vary; most are standard set size, but occasional smaller ones might take longer to mature. But overall, the quality is consistent for the price.

In summary, the CoolBeansNSprouts Mixed Onion Bulb Sets are a practical buy for anyone wanting to grow onions at home. They offer variety, value, and ease of use. While the random mix might not suit those who need specific types, for most gardeners it is a convenient way to start a productive onion patch.

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.

This heirloom variety is known for its cold tolerance, making it a great option for early spring, fall, and even winter gardens. With 200+ seeds per packet, you get plenty to start a decent patch or share with gardening friends. The seeds are non-GMO and open-pollinated, which means you can save seeds from your harvest and replant them year after year. That kind of food security is hard to beat, especially for the price.

One standout feature is the versatility. These green onions grow well both outdoors in the ground or in containers, and they also thrive indoors on a sunny windowsill or under grow lights. If you use hydroponics, they adapt nicely to that setup too. The plants produce small white bulbs and long green tops that are perfect for fresh eating. They add a mild onion flavor to salads, stir-fries, sandwiches, and salsas. Growth is straightforward, and the packets include clear instructions printed on water-resistant paper, which is a thoughtful touch for gardeners who might misplace details.

In terms of build quality, the seeds come from a small family-owned US business, and they are packed fresh. The packet is sturdy and resealable, which helps keep unused seeds viable for next season. The expected plant height is around 12 inches, and they do best in full sun with regular watering and well-draining loam soil. The USDA hardiness zones 3-10 cover a wide range of climates, so most gardeners can give these a try.

There are a couple of things to keep in mind. Since there are no customer reviews yet, you are relying on the product description and brand reputation. Also, because these are a cool-weather crop, they may bolt or become tough in hot summer weather. Plan your planting accordingly. Some gardeners might also wish the packet had more than 200 seeds for large-scale planting, but for most home gardens, this amount is just right.

Overall, the Gardeners Basics Tokyo Long White Bunching Green Onion seeds offer a reliable, affordable way to grow fresh scallions. The cold tolerance, indoor-outdoor flexibility, and seed-saving potential make them a smart buy for gardeners who want a steady supply of green onions.
