How to Sow and Plant

Onions may be grown from seed, from young bare root plants or from sets (small bulbs). Make sure to choose the correct variety for your day length. Southern gardeners should select Short Day varieties; Northern gardeners do best with Long Day varieties; gardeners in the middle of the country should select Intermediate Day varieties, but can use some Short Day varieties.

Sowing Seed Indoors

  • Onion seed may be started indoors in small flats in seed starting mix 6-10 weeks before the last frost.
  • Sow thinly and cover with ¼ inch of seed starting formula. Keep moist and maintain a temperature of about 60-65 degrees F.
  • Seedlings emerge in 7-14 days.
  • As soon as seedlings emerge, provide plenty of light on a sunny windowsill or grow seedlings 3-4 inches beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night. Raise the lights as the plants grow. Incandescent bulbs do not work because they get too hot. Most plants require a dark period to grow, do not leave lights on for 24 hours.
  • Seedlings do not need much fertilizer, feed when they are 3-4 weeks old using a starter solution (half strength of a complete indoor houseplant food) according to manufacturer’s directions.
  • After danger of a heavy frost plant the seedlings in the garden when they are about the thickness of a pencil. Before planting in the garden, seedling plants need to be “hardened off”. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Be sure to protect them from wind and hot sun at first. If frost threatens at night, cover or bring containers indoors, then take them out again in the morning. This hardening off process toughens cell structure and reduces transplant shock and sun burn.
  • Space 3-4 inches apart in rows 1-2 feet apart. Plant more closely if you plan to harvest scallions.

Soil Preparation in the Garden

  • Choose a location in full sun where you did not plant onions the previous year.
  • Apply a balanced fertilizer and work into the soil prior to planting. Onions prefer a pH of 6.0 – 7.0.
  • Onions prefer an organic soil that drains well. Work organic matter into your soil at least 6-8 inches deep, removing stones, then level and smooth.

Sowing Directly in the Garden

  • Sow onion seeds in average soil in full sun after danger of frost in spring. In frost free areas, sow in fall.
  • Sow thinly in rows 1- 2 feet apart and cover with ¼ inch of fine soil. Firm lightly and keep evenly moist.
  • Seedlings emerge in 7-14 days.
  • Thin to stand about 3 inches apart when seedlings are 1- 2 inches high.

From Plants

  • Burpee ships small onion plants about 10 to 12 weeks old in early spring. Plant onion plants as soon as possible after you receive them, as soon as the soil can be worked, before the last frost.
  • Plant onion plants 1 inch deep, 5 – 6 inches apart, or 2 – 3 inches if you prefer to thin later for green onions or scallions. Water well.

From Sets

  • Just press sets into the soil up to their tops, barely covered with soil 3-4 inches apart in rows 1-2 feet apart. If sets are planted too deeply they will take longer to develop.

How to Grow

  • Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating.
  • Ample water is important at all stages of growth, especially when bulbs are forming. Onions are shallow rooted and tend to dry out during periods of drought. The best method to water is by ditch or furrow irrigation. This provides water to the roots while keeping the tops dry. If the tops are regularly wet they are more susceptible to disease.
  • Onions are heavy feeders, side dress with fertilizer about six weeks after planting.
  • Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.

Harvest and Preserving Tips

  • Pick green onions (scallions) when plants reach 6-8" tall, while the stalks are still white at the bottom and fairly thin.
  • When harvesting onion bulbs, about 100 days from sowing, bend the tops over when about ¼ of the tops have already fallen over and turned yellow. After a few days, pull the bulbs and cover them with the foliage to prevent sunburn.
  • Allow onions to dry in the garden for up to a week, then cure them indoors in a warm, dry place with good air circulation for 2-3 weeks. Then cut off the foliage, leaving 1" above the top of the bulb.
  • Clean the bulbs by removing dirt and any of the papery skin that comes loose when you handle them.
  • Put bulbs in mesh onion bags or old pantyhose and store in a cool, dry location. Check occasionally for any wet spots or mold and remove any damaged bulbs immediately to protect the rest.
  • All onions lose their pungency when cooked. To neutralize the flavor, sauté, parboil or microwave the onions briefly before adding to your recipe.
  • To minimize the discomfort of onion tears while chopping onions, work fast (but carefully!) and work closely to the kitchen fan. You can also use a food processor.
  • Besides fresh storage, small onions may be canned by the hot pack method.
  • Chopped, sliced or grated onions may be quickly dried in a food dehydrator and stored in air-tight containers on the pantry shelf.
  • Small whole onions may also be pickled, while larger ones may be used in mixed pickles or to flavor cucumber or tomato pickles.

Onion, Texas Supersweet is rated 4.75 out of 5 by 8.
Rated 5 out of 5 by from Awesome Onion These onions are fantastic. I planted them two years ago in Philadelphia and they grew exceptionally well. I love onions and I have not had any better. I skipped planting them last year - what a mistake - and missed them dearly. They are back in the dirt this season, and I'm counting down the days to harvest.

Rated 4 out of 5 by from Texas Supersweet Onions Just planted my onion plants that came via U.S. Postal Service. They arrived fresh and in great health, I was very happy. This is the first time I have ever planted onions and I'm looking forward the the results. I planted them in several locations in the backyard due to space restrictions, shade, etc. By the reviews I've read it's going to be a sweet outcome.

Rated 5 out of 5 by from Best onion 2014 was the fifth or six year we have grown Texas sweets, and again we didn't have to worry about keeping them for the winter. They are always gone before fall is here. They are named correctly sweet. Wish I had more room to grow a bigger patch,

Rated 5 out of 5 by from great onion! Tastes great and good producer I planted Texas Supersweet in 2012 and it produced great onions that kept fine in a a spare fridge when I harvested in early September. They were all eaten up within a get months since they tasted great! Planting this again in 2013.

Rated 5 out of 5 by from Sweet Onion I tried the Texas Super Sweet onions for the 2011 gardening season and was very impressed with the Texas Sweet Onions. Very good in just about all receipes. They are not a lomg keeper and the taste is very similer to the Vadiua onion. They grew to about 3 to 6 in diameter. Very,very sweet and I will plant for 2012 season

Rated 4 out of 5 by from Big and delicious These onions were great. Big and delicious. Only issue is they didn't seem to keep as long as some other varieties which I have read is normal because of the high water content. I plan to plant these again along with a longer lasting variety.

Rated 5 out of 5 by from Got'a Love'em I grew this particular onion 2 years ago! These onions grew so fast and I had 90% that were softball size, yet they were so Sweet and Tender. I don't think I had an onion left 1 month after harvest. This year I planted a double batch so hopefully I have onions during the winter.

Rated 5 out of 5 by from Only wish I planted more! I figured I'd give these a shot, since I'm very partial to sweet onions, but being in Zone 7, almost coastal NJ, I knew that having a short-day variety was pushing the limit. Well - I only wish I had planted more of them!! They are SO sweet. The bulbs varied in size from small to medium - I didn't get really big bulbs, but the taste makes up for it. They were finished fairly quickly, and I dried most of them for storage, hung them in a mesh net, and keep them in my dark, air conditioned tack room - so far no problems in storage.
