You can plant your sets as early as Onins, but many gardeners prefer to wait until October, when the weather has significantly cooled. You can even plant your sets in the early winter, as long as the ground has not become solid yet.

Select a sunny spot in your garden. Winter onions are hardy enough to grow in a gow of conditions, but they prefer to soak in full sun. Break up the soil. Use a rake or trowel to loosen the soil in your plot. Winter onions do best in loose, well-drained soil.

Avoid using sandy soils, however, since sand causes soil to lose moisture a little too quickly, preventing your onions from soaking in all the nutrients they need to thrive. Mix organic matter into the soil. Sterilized compost is a popular choice. Vrow matter provides additional nutrients and may improve the soil's ability to retain proper moisture levels. Gently push the set into the ground until it is just below soil level.

Cover it with additional soil if necessary, gently packing the soil over the bulb. Space sets 4 to 6 inches 10 to 15 centimeters apart within each row. Each row should also be spaced about 1 foot 30 centimeters apart. Cover your planted sets with a heavy layer of mulch. Groq mulch allows the soil to retain moisture longer and also keeps the onions a little warmer than they would be if the soil remained exposed.

Method 2 of Water the onions twice a week for the first two weeks. After that, avoid watering the onions at all, especially once the ground has frozen. Once the weather warms up again, water the onions only if you experience a drought and the soil contziner hard, cracked, and dry. Give your onions two contaainer of fertilizer.

The first dose should come shortly before the first heavy freeze. If you live in an area where it does not freeze, apply the first dose of fertilizer any time from late October through November. The second dose should be in the early summer, before harvest. Weed the area. Throughout the majority of the onionx season, weeds do not pose much grlw.

When you do see weeds, however, you should yank them up immediately, either by hand or by using a sharp hoe. Weeds will compete with your onions for nutrients in the soil, causing a small, dehydrated crop. Watch out for pests. You will not have much of a pest problem throughout the majority of the growing period, but if you notice any pests once the weather warms up, use a non-hazardous pesticide to kill or ward them off.

Harvest onion greens at any time during the spring. Once the greens reach several inches 10 centimeters or so in height, you can snip them off with shears. They have a mild flavor but work well in many recipes that call for onions. Harvest onion bulbs once the tops go brown. This usually occurs anytime from the late spring to the early autumn, depending on when you planted your sets.

Due to the lengthy growing period, winter onions have notably large root bulbs. Tug on the tops until the bulb comes out or pry them out with a garden fork. Dust off as much soil as possible how to stop people from smoking setting them out to dry. Allow a few of the bulbs to "walk. Once the bulblet grows large enough, the weight of it causes it to sink to the ground and plant itself.

Oftentimes, you can still snip off the stem and the ground bulb after this occurs. Allowing the bulblets to replant themselves ensures a crop for next year.

Introduction: Grow Onions From Discarded Onion Bottoms

May 01,  · Sweet onions refer to a number of onion varieties, including Walla Walla, Vidalia, Sweet Spanish onions, and more. While these onion varieties naturally tend to be less pungent than others, the soil in which you grow them also plays a large part in the final flavor of the onion. Oct 08,  · Winter onions are a hardy vegetable that grow well in colder climates. You’ll want to plant them in a sunny spot during the fall after the temperatures have cooled. Mix some organic compost into the soil, then gently push the onion bulbs into the ground inches apart. Cover the bulbs with mulch, which will help keep the soil moist. I grow store bought ginger and turmeric as well. Also shallots, celery and of course onions. I'm in an apartment and the plants are all outdoors (except I just brought in my celery, thanks to advice below) and no one complains. The key to success is the quality of the soil. You have to have container mix if you plant in containers, not "top soil".

As strange as it may sound, onions are one of our favorite crops to grow! Few pests bother them, and the plants are forgiving and versatile — since you can harvest and use these alliums at many different stages along the way.

Not to mention, onions are the ultimate garden-to-table crop. Just about every killer soup, stew, sauce, or stir fry begins with a familiar foundation: sauteed onions and oil or butter. Toss in some garlic? Read along to learn how to grow onions from seed, seedlings, or sets. This article will teach you everything you need to know, including how to choose the varieties that will grow best in your garden, when and how to start onion seeds, plus tips for transplanting and ongoing care.

Spoiler alert: homegrown onion powder is outstanding! Then as the weather warms up, they switch to focus their energy on bulb formation. Therefore, spring is the best time to plant onions in most places. After sprouting onions take three to five months to reach a mature size, depending on climate and variety. Gardeners with mild winters can also grow onions in the fall for a winter harvest. Here on the temperate Central Coast of California, we can grow onions essentially year-round!

In colder climates, it is also possible to plant onion sets in fall but allow them to overwinter and harvest mature onions in the spring to early summer. In that case, plant onions when the soil is still warm — at least a month before your first fall frost date.

That gives them time to establish healthy roots before they go dormant for the winter. All in all, it may take a little experimentation to figure out the best time to grow onions in your particular climate and garden. One very important key to this puzzle is to choose the right type of onions to grow for your area! Before forming large bulbs, immature onions may be picked and used as green onions — also known as scallions.

Gather up a cluster of young green onions, spring onions, or scallions, and now you have a handful of bunching onions. In addition to size and color, different onion varieties are further classified as either short-day, long-day, or day-neutral onions. It is important to choose and grow onion varieties that are a good fit for your location! Otherwise, the onion bulbs may fail to successfully develop.

As a very general rule of thumb, short-day onions grow best south of the 35th parallel , and long-day onions do well north of the 35th parallel. Ironically, our garden is located almost exactly on the 35th parallel — just a squeak north at We grow impressively large Walla Walla onions a long-day variety during the early spring to summer. There are three main ways to grow onions: from seed, seedlings, or by purchasing onion sets. Every gardener has their preference between the three!

We like to grow onions from seed, or from seedlings we buy at a local nursery. Growing onions from seed is easy, and allows you to choose the exact varieties you want to grow!

Purchasing started seedlings or sets is also a great option, and will give you a quicker start than seed. Onion seedlings are like small green onions, recently started from seed within the last couple months. You can grow your own, or purchase seedlings at your local garden center. You can still eat around the tough center of the onion bulb, but it will decline in quality and no longer be good for long-term storage. To grow onions from seed, you can either start seeds indoors, sow seeds directly outside, or use the winter sowing method.

Planting seeds directly outside is simple. However, starting seeds indoors during winter will put you several weeks to months ahead of schedule.

For northern gardeners with short growing seasons , this is a critical advantage! Plant onion seeds outside in late winter to early spring, once the ground is no longer frozen and can be worked in your area.

Read the soil preparation and site selection tips below before you start. Cover the seeds lightly with soil, and maintain damp to promote germination. Once they sprout, thin to one onion seedling per 4 inches to avoid crowding.

Note that germination rates will be slower and less consistent with this method, and not recommended for northern climates. Start onion seeds indoors about 8 to 10 weeks before the last spring frost date in your area. Follow the common best practices for indoor seed-starting: use a sterile seedling potting medium, keep the soil damp but not soggy, and provide at least 12 hours of bright light per day after germination.

The warm, comfy indoor conditions will help onion seeds sprout and grow quickly. Once they reach 5 or 6 inches or taller , trim the tips of their greens down to 3 or 4 inches. This encourages thickening, stronger root development, and prevents them from flopping over.

Eat those trimmed bits as green onions! I do not thin my onion seedlings until I transplant them outside. I allow a handful of seedlings to grow together in one cell or small pot, and then very gently pull them apart to plant separately come transplant time.

Please visit our Seed Starting article for more details about starting seeds indoors, and our favorite supplies. This is when you sow seeds inside a covered container , but do so outside.

As the name suggests, start your onion seeds outdoors during the winter — between late December to February in most locations. The seeds will stay dormant in the chilly outdoor conditions, and sprout in spring once the conditions are right. Then you can transplant the already hardened-off seedlings to their final location in the garden.

To grow onions with the winter sowing method, select a wide shallow container with drainage holes that can be covered with a clear or opaque dome or lid or, one that already has one. Add at least one or two air holes for ventilation to the cover. Set the container in a sunny location, water as needed to maintain the soil damp, and wait for the seeds to germinate.

Once the seeds sprout, open the container lid on warm days but close them back up on cold nights. Keep watered as needed. If snow or a hard frost is a threat, move the container to a protected location or cover it with a blanket for insulation. Plant onion sets in the garden 2 to 4 weeks before the last frost date in your area. Bury them deep enough that the bulb is mostly under the soil, but with the pointed tip level with the soil surface or just poking out.

Big box garden centers are notorious for selling very zone-inappropriate varieties. Small locally-owned nurseries should offer a much better selection. While this method is certainly easy, it can lead to underdeveloped or flowering bulbs more often than starting from seed or seedlings.

If you do opt to grow onions from sets, choose the smallest bulbs you can find. Sets around a half-inch in diameter or smaller are ideal. Experts say that larger onion sets are more likely to halt bulb development and bolt go to seed and flower sooner than more petite bulbs. Even though onion seedlings can tolerate chilly temperatures, hardening them off first will prevent shock or damage from the sudden change in environment. Learn more about hardening off here.

You can skip this step if you are growing onions from seedlings you purchased at a nursery, or if you used the winter sowing method. Onion seedlings that have been hardened off can withstand a light frost, but need to be protected from a hard freeze. If needed, shelter young onion transplants with frost cover, cloches, buckets, or other protective insulation.

Learn more about protecting crops from frost here. Choose a location in your garden that receives full sun. Some varieties of green onions can handle partial shade, but all onions grow best in ample sun.

If your garden is on the shady side, choose short day varieties to encourage bulb development. Onions grow most happily in moderately rich, well-draining soil. Amend clay soil with organic matter e. Before planting, amend the soil with a balanced, mild, slow-release fertilizer such as this organic all-purpose blend.

Avoid high-nitrogen fertilizers. Excess nitrogen will encourage ample green top growth, but at the expense of the bulb. During the growing season, we water our onions at least once with homemade compost tea. Mycorrhizae are beneficial fungi that promote healthy root development and nutrient uptake for all plants. Onions have shallow root systems, so it is important to keep them well-watered.

A lack of consistent water will result in smaller onion bulbs. Adding a layer of mulch around the onions is an excellent way to prevent the soil from easily drying out. We love to use compost as mulch! It is dual purpose since it helps feed the soil as well as retain moisture.

Remember, good drainage is crucial too! Soggy soil or standing water increases chances of onions rotting. Very few pests are attracted to onions. In fact, onions actually repel many pest insects , including aphids, flea beetles, cabbage loopers, ants, carrot rust flies, and more.

Therefore, onions make great companion plants in the garden! Onions can be interplanted among other pest-prone crops to help provide natural, organic pest control. Interested to learn more? Stop by this article , which also includes a handy printable companion planting chart!
