Short Answer
Onion sets should be planted in early spring or late fall, depending on your local climate.
When planting, make sure to space the sets about 4 inches apart so that the onions have room to grow.
Plant the sets about 1 to 2 inches deep in the soil, with the pointed end facing up.
Finally, be sure to water regularly after planting to encourage the growth of the onions.
What are Onion Sets?
Onion sets are immature bulbs that are planted in the spring in order to grow full-size onions.
The bulbs are small, about the size of a marble, and can be found in garden centers or catalogs.
Onion sets are a great way to get a jump start on your onion crop, as they can be planted weeks before the traditional onion seeds.
When planted properly, onion sets can produce a full-sized onion crop in as little as 6 to 8 weeks.
They are also a great choice if you live in an area with short growing seasons, as they mature more quickly than traditional onion seeds.
Benefits of Onion Sets
Onion sets are a great way to get an early start on your onion crop. Planting onion sets is a simple and straightforward process that can provide a number of benefits. Here are just a few:
First, planting onion sets is an efficient way to get a head start on your onion crop.
Onion sets are small onions that are harvested before they reach maturity.
By planting them in the spring, you can get a jumpstart on your crop, allowing you to harvest your onions sooner.
Second, planting onion sets allows you to avoid the hassle of starting from seed.
Growing from seed can be a time-consuming process, involving germination and the need to start seeds indoors.

Third, onion sets are generally less vulnerable to disease and pests.
Onion seedlings are particularly prone to disease and pests, making them hard to keep healthy.
Onions sets, on the other hand, are more mature and better able to resist these issues.

Onion sets are usually much cheaper than starting from seed, allowing you to get a good harvest without breaking the bank.

Caring for Onion Sets
Once you’ve planted your onion sets, there are a few key steps you should take to ensure they thrive and you get the best yield.
The most important step is to keep the soil moist.
Make sure to water your onion sets regularly, especially during periods of dry weather.
Additionally, you should mulch around the sets to help them retain moisture and prevent weeds from overtaking them.
If you live in an area with a longer growing season, consider adding a light fertilizer to the soil to help boost the growth of your onion sets.
Once your onion sets have grown to full size, you should thin them out by cutting the leaves off the weakest plants.
This will help the remaining sets get the best chance of success.
Finally, make sure to harvest your onions when the tops of the plants start to yellow and fall over, usually around mid-summer.
This is the best time to harvest onions while they are still at peak flavor.
Harvesting Onion Sets
Harvesting onion sets can be a rewarding experience for any gardener.
Typically, onion sets are ready for harvest in late summer, after the foliage has died back and the bulbs have reached their full size.
When harvesting onion sets, it is important to wait until the tops of the onion bulbs have turned yellow and the necks have dried out.
This is an indication that the onions are ready to be harvested.
To harvest, use a garden fork to gently loosen the soil around the bulbs.
Then, use your hands to carefully remove the bulbs from the soil.
Once harvested, shake off any excess soil and lay the onions out to dry in an area with good air circulation.
Once the onions are completely dry, they can be stored in a cool, dry area in a mesh bag or burlap sack.
Be sure to check the onions periodically for any signs of spoilage, such as mold or soft spots.
If any spoilage is found, discard the affected onions immediately.
With proper care, onion sets can be stored for up to nine months.
Once the onion sets have been stored for a few months, their flavor will improve and they will be ready for use in your favorite recipes.
