7. There’s Quite A Variety of Onions

Perhaps you’ve already cultivated onions in your garden but have been somewhat disappointed by a less than thrilling harvest of small bulbs. It may not be your soil or growing technique that’s at fault. You may have started with the wrong onion.

Bulbs vary in size, shape, color, and pungency dependent on soil conditions and growing temperatures. Warmer growing areas tend to produce a milder and sweeter flavored onion. Each different type of onion presents flavor and texture attributes or growing condition requirements that make it the best type of onion for your particular growing conditions.

When it comes to size, onions range from quite tiny, at less than 1/2 inch around, to large orbs 5 inches or more in diameter. A seasonal vegetable, onions are divided into two main classifications. Spring and summer onions, available March through August, and Fall and Winter onions, available August through May.

8. Storage Life Depends on the Onion Variety

Sweet and mild flavored, spring and summer onions, with lighter, thinner skin and higher water content, have a shorter storage life. Fall and winter onions tend to have thicker skins, are darker in color, and contain less water: thus, an extended storage life. Winter onions also tend to provide a heartier flavor and present a more pungent aroma.

5. The Onion Itself Doesn’t Make Us Cry

An onion’s pungency results from the level of sulfur-rich volatile oils the onion contains. During peeling or slicing, the volatile oil is released. The oil released is what causes eyes to water and burn when chopping an onion.

9. Onions Flourish In A Wide Range Of Soil Conditions

Hardy, easy to grow, easy to transport, and easy to store, onions are an ideal crop to add to the homestead garden. Commercially, most onions are grown from the plant’s small seeds sown in early spring. However, most home gardeners get a jump on the growing seasons by starting onions from small bulbs or transplants. Contact your local county extension office for helpful advice on when to plant different varieties of onions in your particular part of the county.

10. Onions Love The Sun

Select a sunny spot in the garden for your onion patch. Onions can tolerate a bit of shade but prefer a location with full sunlight. Onion bulbs grow in response to daylight. When daylight hours reach a certain level, onions start forming bulbs, also known as bulbing.

Short-day onions require only 10 daylight hours to develop to their full potential. Long-day varieties require 15 hours of daylight to form bulbs. Savvy gardeners advise choosing day-neutral varieties, which perform well regardless of day length and do well in most any region.

11. Onions Don’t Fare Well In Heavy Clay Soils

Onions are heavy feeders and do best in nutrient-rich, loamy, well-drained soil. Before planting, work the soil well, breaking up dirt clods and removing rocks and weeds.

Work the soil at least 8-12 inches deep. Avoid working wet soil, which causes soil compaction. Compacted soil keeps air and moisture from reaching plant roots, thus hindering vigorous growth.

Supplement soil with generous amounts of well-aged herbivore manure (cow, sheep, horse, goat, llama) and incorporate well into the soil. Worm castings are also an excellent soil supplement for growing onions.

The soil mixture for onion cultivation should be about 20 percent well-aged organic compost. Avoid commercial fertilizer supplements that contain sulfur, which reduces the sweetness of the harvest.

12. In The Produce Section, The Onion Is Surrounded By Relatives

The common onion (Allium cepa L.), also known as the bulb onion, is a popular vegetable, widely cultivated around the globe. Onions are Asian herbs, members of the lily with pungent edible bulbs: The most cultivated of all plants in the genus Allium.

The genus Allium includes leeks, chives, shallots, and garlic as well as pearl onions, green, red, yellow onions, and Chinese onions. The term ‘onion’ is often used as the generic name for any of the hundreds of plants in the genus Allium.

13. There Are Short-Day, Intermediate-Day, And Long-Day Onions

Experienced onion growers report that success lies in allowing the plants sufficient time to form solid, large bulbs. If you live in an area with mild winters, the best way to grow the sweetest onions is to plant bulbs or transplants in late summer or early fall and let them grow and mature through the winter.

Sweet onions are mild and flavorful, lacking the sharp and slightly tart taste of winter onions. They are a mouth-watering treat when sliced very thin and served in salads, sandwiches or with your favorite burger.

Short-Day Onions

When selecting sweet onion bulbs for over-winter planting, look for varieties known as short-day onions. This type flourishes despite the short days of winter. Short-day varieties are considered cold-hardy down to 20 degrees Fahrenheit.

Short day onions produce the best bulbs when given 10 or more hours of daylight: ideal for southern regions in United States plant hardiness Zones 7 or warmer.

If you reside in a colder climate but would still like to cultivate sweet onions, they can be started indoors and transplanted out in early spring. Grown this way, they will be mild and sweet, but will not mature to the same magnificent size as those grown outdoors all winter long.

Favorite varieties of short-day sweet onions include:

  • Maui Maui
  • Texas Sweet
  • Red Texas Sweet
  • Georgia Sweet
  • Bermuda Sweet
  • White Granex
  • White Bermuda

Intermediate-Day Onions

Also known as day-neutral onions, intermediate-day onions are cold-hardy to 0 degrees Fahrenheit. Intermediate types of sweet onions do fine in colder climates in plant hardiness Zones 6 and colder.

A variety known as Candy Onion is the most widely planted variety of day-neutral onions. Red Sweet and Cimarron are also widely grown.

Long-Day Onions

Requiring 15 hours of daylight to promote bulbing, long-day onions are also the slowest type of onion to mature. If your growing region does not receive this amount of average daylight, long-day onions will never form bulbs. Plan 90-110 days from planting to harvest time.

Favorite varieties of long-day onions include:

  • Walla Walla Sweet
  • Spanish Sweet
  • Vidalia
