  • Works well in containers, making it accessible for small spaces
  • Produces sweet onions with proper watering and full sun exposure

Detailed Review

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.

Detailed Review

The Vegetable Gardener's Container Bible is a comprehensive resource for anyone who wants to grow fresh food in limited space. Written by Ed Smith, author of the best-selling Vegetable Gardener's Bible, this book zeroes in on container cultivation. It covers everything from selecting the right pots and soil to watering, fertilizing, and pest control. Whether you have a small balcony, a patio, or just a sunny windowsill, Smith shows you how to turn it into a productive vegetable garden.

What really stands out are the detailed photographs and the author's straightforward, experience-based advice. Smith explains how to create your own potting mix and build self-watering containers.

The book includes growing guides for dozens of crops, from tomatoes and peppers to lettuce, herbs, and even pumpkins. Real-world user reviews highlight how this book helped beginners successfully grow their first patio garden and gave seasoned gardeners new techniques to try.

The physical book itself is well-bound on quality paper with vivid images. At 264 pages, it's substantial but not overwhelming. The layout uses clear headings and bullet lists, making it easy to find information quickly. However, some readers note that the author heavily recommends self-watering containers, which can involve extra cost or DIY effort. Also, the guidance is tailored to North American climates and seasons, so gardeners in other regions may need to adjust timing.

Overall, this is a trusted, practical resource that delivers on its promise. It earns a high rating from over a thousand reviewers for a reason. If you're committed to growing your own food in containers and want a single book that covers everything from start to finish, this is an excellent choice.

Detailed Review

The Stargazer Perennials Mixed Onion Sets offer a practical way to start a home onion patch. This 1-pound bag contains a random mix of red, white, and yellow onion bulbs, all non-GMO and grown in the USA. It's designed for gardeners who want a simple, all-in-one solution to grow multiple onion types without buying separate packs. The included tip sheet makes it accessible even if you're new to growing onions from sets.

What stands out is the variety. The mix includes intermediate, day-neutral, and long-day varieties, so it adapts to different regions and seasons. You can plant them in a vegetable garden, raised bed, or container, and even grow them indoors near a window. The flexibility to harvest young as salad greens or let them mature into full-size onions adds real value. Expect roughly 80 to 100 sets per pound, though the exact count depends on bulb size.

In terms of quality, the bulbs arrive hand-sorted and ready to plant. The growing guide covers spacing (3 to 6 inches apart), when to pull (after tops fall over), and curing instructions (14 days in a cool, dry spot). This attention to detail helps ensure a successful harvest. The sets are firm and viable, with no signs of damage in typical shipments.

One limitation is that Stargazer Perennials cannot ship to Washington or Idaho, so gardeners in those states need to look elsewhere. Also, because the mix is random, you won't know the exact ratio of colors until you open the bag. Some users might prefer a more predictable assortment. But for most home growers, this is a minor trade-off for the convenience and variety.

Overall, the Stargazer Perennials Mixed Onion Sets deliver on their promise. They're a reliable, no-fuss option for anyone wanting to grow a colorful onion harvest. The non-GMO sourcing, included guide, and flexible planting options make it a solid buy for both beginners and experienced gardeners. If you're in a state where shipping is available, this pack is worth considering for your spring planting.

This is a half-pound mix of red, white, and yellow onion sets from TomorrowSeeds, offering about 50 bulbs for a colorful, easy-to-grow harvest. It's ideal for beginner and seasoned gardeners who want fresh green onions early and storage onions later, with strong growth and long shelf life.

Cons

  • Some bulbs may be small or soft upon arrival, though most still sprout successfully.
  • Color distribution can be uneven, with fewer yellow sets than red or white in some orders.
  • Not ideal for gardeners seeking a single onion type or precise quantity of each color.
Detailed Review

The TomorrowSeeds 3 Colors Mix Onion Sets bring a fun and practical twist to home gardening. This half-pound pack contains roughly 50 individual bulbs, blending three popular onion varieties: Yellow Stuttgarter, Red Karmen, and Snowball White. It's designed for gardeners who want both early green onions and full-sized storage bulbs later in the season. Whether you're a beginner or have years of experience, these sets make it easy to grow a colorful, productive crop.

What stands out most is the mix itself. Each variety offers a different flavor profile: the yellow onions are classic and savory, the reds add a sharp, zesty bite, and the whites bring a mild sweetness. This diversity is perfect for cooking, from fresh salads and salsas to hearty soups and roasted dishes. The bulbs are GMO-free and cold-stored, which helps them stay fresh and ready to plant. Many buyers report that nearly every bulb sprouts within a week, even the smaller ones, leading to a robust harvest.

In terms of performance, these sets are reliable. They thrive in full sun to partial shade and adapt to sandy soil with moderate watering. The intermediate-day length means they work well in many regions, not just specific zones. Storage life is excellent, so you can enjoy your homegrown onions for months after harvest. The only real downsides are occasional soft or moldy bulbs in the pack, and some customers note that the color ratio can be skewed toward red and white, with fewer yellows. But overall, the germination rate is high, and the value is solid.

Build quality is good for a natural product. The bulbs arrive firm and smell fresh, though a few may be small or slightly soft. That's typical for onion sets, and most still grow fine. The packaging is simple but protective, ensuring they reach you in good shape. For the price, you get a lot of potential harvest in a single order.

If you want a straightforward way to grow a mix of onions without buying separate packs, this is a smart choice. It's especially good for gardeners who like variety and don't mind a little unpredictability in color distribution. The pros far outweigh the cons, and the positive reviews from repeat buyers speak for themselves. I'd recommend it for anyone looking to add some homegrown flavor to their kitchen.

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.

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.

Frequently Asked Questions About Planting Onion Sets in Containers

Here are answers to common questions about how to plant onion sets in containers based on real gardener experiences and product feedback.

What container size is best for planting onion sets?

A container at least 6-8 inches deep with drainage holes works well. For multiple sets, use a wider pot or a planter box (like those featured in our planter box guide). Onion roots are shallow, so depth is less critical than width for spacing.

How many onion sets can I plant in one pot?

Space sets about 3-4 inches apart for full bulbs, or closer for green onions. A 10-inch pot can hold 4-5 sets. Many of the how to plant onion sets in containers products we list, like the Mixed Onion Assortment, include 50+ sets, so you may need several containers or a raised bed setup.

Do I need special soil for container onions?

Use a well-draining potting mix enriched with organic matter. Avoid garden soil because it compacts in pots. For best results, mix in a balanced plant food before planting – check out our best plant food for window boxes guide for container-friendly options.

When is the best time to plant onion sets in containers?

In most climates, plant onion sets 2-4 weeks before the last frost in spring. They can also be planted in fall for a spring harvest in mild zones. The how to plant onion sets in containers process is simple: push the set into the soil until the tip is just visible, water well, and place in full sun.

Can I grow onions indoors under grow lights?

Yes! Onions need 12-14 hours of bright light daily. If natural light is low, use a full-spectrum grow light. For more indoor growing tips, visit our Grow Lights category. The StargazerPerennials and TomorrowSeeds sets in this list are great for indoor containers.
