What Are Short Day Onions: Producers of onions often refer to onions as “short-day onions,” which means onions that need fewer sun hours to start growing bulbs under the soil. Onion bulbs form when the temperature and length of sunshine are just right. This sets off the Onion’s internal clock. Long-Day onions need 14 to 16 hours of sun, but Short-Day onions can start to bulb at 11 to 13 hours.
Onions need sunshine to have a lot of top growth before the bulbs form, and the amount of top growth is strongly linked to the size of the bulbs. One type of Onion stops growing at the top and starts to form blooms when the length of the day is right for that type of Onion.
People who live in places with warmer winters and shorter days, like the South-South, usually plant Short-Day Onions in the fall. This deliberate time delays bulb formation until spring, when there are the most daylight hours, which lets the tops grow at their fastest.
At a latitude of about 32 degrees north, the line of separation in North America goes from the middle of Georgia to the southern part of California. Short-day onions tend to start bulbing too early in the north after this latitude, making smaller bulbs that look like pearl onions. In places where it is very cold, like Canada or Scotland, where days can last up to 14 or 20 hours, Short-Day Onions might not be able to grow bulbs.
Benefits of Planting Short-Day Onions
There are many benefits to growing short-day onions, such as:
Early Harvest: Onions grown on short days are ready to be picked earlier than onions grown on long days. This makes them a great choice for gardeners who want to start the growing season with an early crop.
The short-day Onion does best in warm winters and early spring. It can also grow in other climates. Their ability to make lights with fewer sunlight hours makes them useful in a wider range of climates.
Onions that grow in short days are less likely to bolt, which is when the plant gets a flower stalk too early. This trait makes it less likely that the bulbs will get smaller and less good, which raises the chances of a successful harvest.
What varieties are short day onions?
Different types of short-day onion cultivars have different tastes and traits. Some of the most well-known types of short-day onions are:
Georgia Sweet: This short-day onion type is known for its unique sweetness. It’s great for people who like mild to sweet onion flavors.

Texas Super Sweet: This type of Onion is known for being very sweet, and people who like onions with a sweet flavor really enjoy it.
Because it tastes mild and sweet, Texas Sweet White is a great twist for people who like white onions with a bit of sweetness.

White Bermuda Onions: These onions can be identified by their bright white bulbs. They have a mild taste and are often used in salads, sandwiches, and other dishes.
All of these short-day onion cultivars give gardeners and chefs a lot of flavor choices when they’re making food, and each one brings something special to the table.
Are Spanish onions short day onions?
People who want a standard large sweet onion often choose the White Sweet Spanish Onion, which is also known as a long-day type. This onion variety comes from the same family as the Yellow Sweet Spanish, but it tastes very sweet and not harsh like some onion types do.
The sweet white Spanish Onion grows best when there are 14 to 16 hours of daylight every day. This is because it is a long-day onion. This makes an onion that is bigger than usual and tastes sweeter than usual onions.
The white sweet Spanish onion tastes milder than the yellow one, so it’s a better choice for people who like onions’ sweetness but don’t want their sharp bite. Because of its high quality, it can be used in many cooking situations and gives food a nice, mild flavor.
People who want a large, sweet onion with a mild flavor can count on the sweet white Spanish Onion, which grows well in both the kitchen and the yard. Its unique taste and adaptability make it popular with both gardeners and chefs, showing how different onion types can be.
The Difference Between Short Day and Long Day Onions
Usually, onions are put into groups based on how much sunshine they need to grow bulbs. These onions are called short-day, intermediate-day, and long-day onions. When the days get longer—ten or twelve hours—short-day onions start to grow bulbs. These onions do best in the southern United States and have a sweeter taste. Because they have a lot of sugar and water, they should be used right away in cooking and shouldn’t be stored for a long time.
Long-day onions, on the other hand, do better in northern areas because they need 14 to 16 hours of sunlight to grow bulbs. These onions, which have more sulfur and less sugar, keep well and are ready to use right away in the kitchen. It’s very important to pick the right day length because putting the wrong kind of Onion in the wrong place can keep it from growing to its full potential.
To help you make this choice, imagine a line going across the United States from San Francisco to the southernmost point of South Carolina. People who live north of this line should plant long-day onions for spring and summer, while people who live south should plant short-day onions. People in many places can grow intermediate onions because they do well in both northern and southern temperatures.
Onions, But No Tears – Growing Short Day Onions.
When another Master Gardener gave me some garlic and told me it was easy to grow, I made it a top goal to grow it this winter. It has been easy to grow garlic for four years, just like she said it would be. However, this year, I was driven by a desire to grow my favorite Walla Walla sweet onions.
Usually, the sweet corn is picked in late August or early September. Then I get my garlic bed ready. This area gets enough winter sun, which is important for garlic and onions. To make the earth better, you can mix compost and chicken dung into it. Stir the dirt around a lot to make it loose and easy to drain. Onions were put right on top of raised beds that were six feet long and one foot wide. I made my choice after reading that sweet onions grown from seeds can survive the winter and store better than sets. Sets don’t work as well for me, and straight seeding works better than flat seed starts.

In the South-South, where the change in daylight hours between summer and winter is less obvious (Zones 7 and higher), growing short-day onions is a good idea. Different types of short-day onions are grouped by how well they adapt to the length of the day. For example, short-day onions turn into bulbs when they get about ten hours of sun.
Onions with shorter days do better in the South, while onions with longer days do better in places where the days are longer. Daytime changes less dramatically from season to season in zones seven and up, so they are good places to grow short-day onions. The South is a great place for these onions because their bulbs grow best when there is less sun.
By planting short-day onions, gardeners can make the most of the long days in these places and get a good crop of onions. In the South, where summer days are about the same length as winter days, this systematic approach of choosing onion types based on day length makes gardening more successful and produces more.
How do you grow onions in a short day?
Sow short-day onion seeds in late summer in rich soil with some light frost protection for overwintering to harvest onions in late spring, when 10-hour days promote bulbing. Note: Planting long day varieties in the South means you will never get any bulb development because there is not enough light.
In late summer, plant short-day onion seeds in rich soil that will be protected from light frost during the winter.

Onions can usually handle temps as low as 20°F, but we’ve seen them live in temperatures as low as 17°F. Short-day onions do best when moved in the fall and left to overwinter in places where they don’t get below the low 20s. It is best to wait to move plants until late winter in places where temperatures regularly drop below 20 degrees Celsius.
Onions usually grow from a seed to a plant that can be moved in five to six weeks. Going backward from when you want to plant, keeping the five to six-week window in mind, will help you find the best time to plant. To make sure the onion seeds sprout well, you should grow them in a greenhouse or seed starting room where the dirt is at least 70°F. It usually takes 8–10 days for onion seeds to sprout, but if the dirt isn’t very good, it can take up to 2 weeks.
