Onion, long Day White Spanish

  Onion, Spanish Sweet White

Heirloom. Organic. White Sweet Spanish is a long-day type best suited to Northern regions but grown as a fall onion in the South. Spanish onions are easy to peel and have a mild taste that cooks love. Set transplants 6 inches apart in rows 12 inches apart, planting 1 to 2 inches deep. Use White Sweet Spanish onions for sautéing and grilling. White Sweet Spanish produces a large, globed shaped white onion. A medium to fair storage onion.  Onions are mild, sweet and have a white skin.  If you've never raised onions, here's a quick overview. Onions are biennial plants (which means that they can survive winter and grow for 2 years) but they can be harvested annually. Onions grow best in temperate climates without extremes of heat or cold. The time of year when onions are planted affects when they form bulbs. If you plant your onions too late in the season, they may not form bulbs properly. Onions come in two different classes: long-day and short-day onions. Long-day onions are more appropriate for northern states because they are adapted to longer days. Southern states should use short-day varieties of onions.

Planting Spanish Sweet White Onion

While starting seeds of the Spanish Sweet White Onion is not necessarily difficult, the right conditions will make the process successful. Sow Spanish Sweet White Onion seeds directly in the ground in the spring when the threat of frost has passed or start in containers several weeks before transplanting into soil. Keep the ground moist but not wet for the first couple of weeks. Pick a sunny, well-drained spot for planting for the best performance. Spanish Sweet White Onion prefers a well-drained fertile soil in a sunny position. 

Height: 24-30”    Days to harvest—90 to 105 Days

Spacing: 4-6" inches Depth: 1/16  inch Germination: 15-25 days

Starting from Seed Indoors

Generally, the time to start your seeds is about 6- 8 weeks before the last expected spring frost date in your area, planting the seedlings outdoors about 2 weeks after that date. Another way to figure is to plan on setting out sturdy seedlings in the garden when night temperatures stay in the mid-50 degree range both day and night. Count back and sow seeds 2 to 3 weeks before that date normally arrives. Place a few seeds (5 to 10) into each pot and push them into the soil with your finger. Cover the seeds to a depth of approximately 1/16 inches of the potting mix. Mist each  pot with water until the soil appears moist. Place the pots in an area which will provide both light (which is required for germination) and heat, preferably about 65 to 70 degrees F and at least 8 hours of light each day. Check on the seeds every day and keep the seeds damp but not drenched by misting with your plant mister. You should see sprouting in about 15 to 25 days. Once your seedlings have reached about 4 to 6 inches in height, choose an area in your garden to transfer them. You can also use containers like barrels or clay pots. Dig holes twice the width and depth of each of your pots. Fill up each hole with water then let it drain off. Place a pot in the hole center and level so that your seedling is at the same level as the surrounding soil. Push dirt in carefully all the way to fill the hole back up. Water each seedling carefully so as not to soak the leaves or stem. Onions like rich soil, add lots of organic matter to the soil before planting. 

Direct-seeding into the Garden

Turn over the area you've selected to a depth of approximately 1/2 inches. Rake the area until it's level and smooth. Water the area until the soil is damp but not saturated. Scatter the seeds in the area. Gently rake the area to distribute the seeds further and protect them from birds. Or, press the seeds into the soil and cover with no more than 1/16 inches of soil. You can also place 2 to 3 seeds every 3 to 4 inches in rows approximately 8-10 inches apart, and cover seeds with 1/16 inches of soil. Place planting stakes around the area so you will know where to water. Check on your seeds about once a day. Make sure to mist the soil whenever it appears dry. Germination for Spanish Sweet White Onion plants is approximately 15 to 25 days, depending on the warmth of the soil.   

Germination Problems

Growing plants from seeds successfully depends on a lot of factors and this makes it impossible to guarantee success on every batch of seeds planted.  Factors include, soil composition, PH, temperature, moisture levels, seed depth, soil density, seed viability, seed storage and many others.  We tested the germination of all our seeds and this seed variety is around 80%, but your results may vary based on exactly how you plant and all the environmental factors.  Good luck.
