How fast do onions grow




















Once the soil has warmed, put down a mulch around and between the plants to discourage weeds and to hold moisture in the soil. Dry conditions cause bulbs to split, so water when necessary to provide at least 1 inch of water each week; keep in mind that transplants require more water than sets do. Onions can't compete well with weeds, so it's important to direct water right to the onion roots.

If you've prepared your soil well, no fertilizing should be necessary. Always go easy on nitrogen , which can produce lush tops at the expense of bulbs.

New growth from the center will stop when the bulbs start forming. Egyptian onions, chives, and shallots require slightly different cultivation from regular onions.

Here are some guidelines for growing these onion relatives:. Egyptian Onions Plant Egyptian onions in fall throughout the country; harvest some in spring as green or bunching onions.

In mid-summer or fall, miniature bulbs will form at the stem tip, where most onions form flowers. Pick these tiny bulbs when the tops begin to wilt and dry. Use them fresh or store in the freezer. Chives Plant chives and garlic chives in early spring in rich soil. They will tolerate partial shade put prefer full sun.

Seeds are very slow to germinate, so most growers prefer to plant clump divisions, which you can harvest after two months. Space the clumps, each of which should contain about six bulbs, 8 inches apart. Cut the grass-like, hollow tops frequently to maintain production. The pom-pom-like lavender flowers are very attractive, but always remove the spent flowers to reduce the chance of rampant self-seeding.

Dig up, divide, and replant every third year. Transplant to containers and move indoors for winter harvests. Chives are almost as good frozen as they are fresh. Shallots Shallots, a favorite of French chefs, have a blue-green stem that's used when young. In addition, it has a gray, angular, mild-flavored bulb that's related to the multiplying onion and is used like a mild-flavored garlic. Shallots will tolerate all but the most acidic soils, but dig the earth deeply because the plants put down 8-inch-long feeder roots.

However, they have no lateral roots, so space them just 2 to 3 inches apart. Propagate shallots by dividing bulb clusters. Each clove, in turn, will produce four to eight new bulbs. In February or March, plant them 1 inch deep, barely covering the tip of the clove. Keep the soil weed-free and slightly moist, but don't fertilize.

In early summer, draw the soil away from the bulbs. All you need is a packet of onion seeds, a plastic lidded container, and some potting soil formulated for seed starting. I start planting onion seeds via winter sowing anytime between early December and mid-February.

Once the seeds are planted, put the container in a protected, shady spot outdoors. I keep mine on a picnic table against the back of our house. The seeds will be fine. Related post: Winter sowing containers. When the temperatures and day length are just right, your onion seeds will start to sprout inside the container.

At that time, you need to start monitoring the moisture level inside the container, watering your seedlings when necessary. Open the lid on warm days and close it at night. If you get a hard freeze in the spring, after the seedlings have germinated, toss a blanket or towel over the container at night for added insulation. Planting onion seeds by winter sowing means the plants are subjected to the natural day-night cycle right from the time of their germination.

This means that bulb set is triggered at the correct time and the plants can form large bulbs before hot temperatures arrive.

Try planting onion seeds instead of sets this year, and enjoy a prolific harvest of these beautiful bulbs. Pin it! Give it a try and let us know how it goes. Yes you can, they are even hardier than onions! When I put shallot sets in the ground, I do it as the same time as I plant garlic in the late fall, not spring!

I have a question do you think this sowing of onion seeds in the winter would work on potato seeds? Typically when grown from seed, they need more than one season. I need to try this method! How fascinating. It will be nice to plant them and leave them to do their thing for a while.

Winter Sowing works for most plants, too, in my experience! They grow best when the time is right for them, and they know that time better than any of us and what we try to replicate with grow lights and perfect conditions. Plants are hardy and know what to do to thrive! Even using indoor lights and putting them out in sheltered areas before finally transplanting them, my results were not as good as I had hoped. The seedlings were somewhat spindly.

A couple of days ago I did my winter sowing and placed the plastic container in a shady area. Lets hope things work better for me!! Wish me luck, lol. Love this idea! Thank you. Try it with a few seeds and let us know if your growing season is long enough for it to work.

I keep mine in full shade, though as the spring temperatures warm, I open the lid and gradually start to expose them to more sun in the week or two prior to planting them out into the garden. I planted seeds in an heated propagator in mid-january in a cold but well-lit room.

They are now happily sprouting. Jessica, Thank you for a wonderful, informative website devoid of noisy, blinking advertisements. Will let you know the results this summer. Any suggestions on keeping the onion maggot flies at bay? Thanks, Mary, for your kind words. Report back with how your onion seed planting goes. As for the onion maggot flies, I suggest covering your onions with a layer of floating row cover also called reemay fabric. It will keep the female flies from laying eggs that turn into those nasty little maggots.

Good luck! Water the seeds in right after planting and then leave it go. How large do the seedlings have to be before transplanting? More like the thickness of embroidery floss. Could you please give me the measurements on your plastic containers. I say No, they are a little bigger than a strawberry container. As you said… about the size of a lettuce container. Hi Barbara.

Thanks Jessca. I was surprised they were that big. My husband will be hapoy he was right. I did plant two packets of onion seed as per your instructions. See photo. My container was about the size you said but not as deep. It does have a high plastic cover and should work. I have done winter sowing before but never tried growing onion from seed. Are their varieties that can store for longer periods of time? Thanks in advance! Hi Jamie — Welcome to Savvy Gardening! Any of the long-day onion varieties listed in the article will work for your zone.

They all store about the same, as long as they are cured properly and you ensure the storage conditions are correct. Go for it! Still worth a try? Hi Jessica, I live in southern York co.

Pa in zone 6b. I planted yellow and red onion seed in the middle of February. Please tell me they will sprout when it warms up and have time to mature. I followed your directions exactly, even have high mowing seed. Thanks Michael. Hi Michael.

Mine have just started to sprout here in Western PA. Would it be to late to try this method in central Wisonsin? Also, how do you transplant your seedlings? Do you just separate the seedlings a push them in the ground a couple is inches apart? Sorry, seedling myself! You could certainly try it, but I would also start some seeds indoors under grow lights as a back up.

Once the seedlings are a few inches tall, transplant them into the garden, spacing them about inches apart. I had just about given up on my onion seed germinitating but today I checked again and they had finally germinated. It took 6 weeks.

Most perennials are easy to start via winter sowing. You can do tomatoes and other warm-season veggies this way, too, but you should delay planting the containers until early spring and bring them inside if the weather is going to get very cold, especially at night.

How deep do you plant the onions during transplant? It is absolutely awesome your number one! Thanks for the information I feel more confident now. If you have had not pest or disease problems in the current location and if you are constantly renewing the soil with the addition of aged compost then you can continue to plant in the same spot.

Onions will deplete the soil of nutrients so it is important to continue to renew soil nutrients with the addition of compost or a commercial organic planting mix add several inches to the planting bed each year. If disease or pests appear, it is best to rotate the onions to another planting area for at least 3 years.

You only need one seed to produce an onion bulb. However, most gardeners plant a few more seeds than they need when it comes to harvest; this allows for seed and plant failure over the course of the growing season. To produce an onion bulb you can plant a seed or a set—a set is a small onion bulb it was grown last season—and gives the grower a head start on seed starting. You can find seeds or sets at a nearby garden center or nursery.

Pine straw—dry dropped pine needles—can be used as a mulch throughout the garden. Keep in mind that pine straw if allowed to decompose or if turned under in planting beds can make the planting bed more acidic.

You can use pine straw around onions to keep weeds down and to slow soil moisture evaporation in hot weather. Check your soil pH before you turn pine straw under. Thank you. Thanks for the great advice. I am about to plant my sprouted onions in the ground today.
