Customer Reviews
Very fun to grow! My first attempt at growing onions and they were very good!!Definitely a smaller variety, which I didn’t realize when I purchased, but they turned out to be quite delicious.
Having White, Red and Yellow onion sets is an excellent choice. Our 300 sets all took and are growing with enthusiasm. Quality and 100% result.
Our onion sets arrived in good condition and are growing well.
I decided to order these from Territorial Seed because the sets I have purchased locally in the past haven't done well. I planted all 100 and ALL 100 came up. They are now about 6 to 8 inches tall and looking good. I hope the bulbs get big, but I won't know for awhile. These are supposed to keep well in storage. Gardening is all about hope. If they do well, I will order again next year.

Allium cepa Days to maturity are calculated from date of direct seeding.
Culture
• Onions are photoperiodic plants — they regulate their stages of growth by day length
• Onions will make top growth until the critical light duration is reached, then bulbing begins
• The amount of growth and development prior to bulbing will determine the bulb size
• Long-day varieties do well in northern states where summertime day length is between 14-16 hours
• Short-day varieties do well in southern states and bulb when day length is 10-12 hours; they won't get very large in northern states
• Dividing line between short-day and long-day varieties is generally accepted as 36° latitude, roughly along the Kansas/Oklahoma border
• Day-neutral and intermediate-day varieties start bulbing when day length is 12-14 hours; can be successfully grown anywhere
• Onions prefer light, sandy, loamy soils
• Apply 1/4-1/2 cup of TSC's Complete fertilizer per 5 row feet, 1-2 inches below transplant or seed
Direct Sowing
• Thin to the strongest plant when 4-5 inches
Transplanting
• Sow up to 10-12 seeds in a 4-6 inch pot
• If tops reach over 5 inches before transplant, cut to 3 inches
• When planting out carefully separate the seedlings and place in a shallow trench
• Fill trench around seedlings and water in well
Insects & Diseases
• Common insects: Onion thrips and maggots
• Insect control: Pyrethrin or Predatory Nematodes
• Common diseases: Fusarium basal rot, pink root
• Disease prevention: 5-7 year crop rotation
Harvest & Storage
• For scallions: harvest when pencil size or larger, wash and trim roots, store in a bag at 36°F and 95% relative humidity
• As bulbs approach maturity, withhold water so protective paper can form
• After about half the tops have fallen, push over the remainder; wait about 1 week then harvest
• Cure in a warm (75-80°F), shaded, well-ventilated location until outer skin and necks are dry, then trim tops, leaving one inch above the bulb
• Store in a cool, dry, well-ventilated area
• Check occasionally and immediately remove any sprouting or rotting onions
KEY TO ONION DISEASE RESISTANCE AND TOLERANCE
HR indicates high resistance.
IR indicates intermediate resistance.
F | Fusarium Wilt

What is pelleted seed?
Seed that has been coated with a clay-based material to form a larger, round shape. This makes planting by hand or mechanical seeder easier and allows for more controlled sowing of small seeds such as carrots or lettuce. All pelleted seed has a National Organic Program (NOP) approved coating.
For best results, store pelleted seed in an air-tight container and use within one season.
What is seed tape?
Seed tapes are perfectly straight rows of precisely spaced crops. No more having to thin seedlings! This biodegradable tape will plant a row 5 meters (16 feet, 5 inches) long. Simply lay it in a furrow and cover with a light layer of sifted compost or soil, water and wait. Save yourself a heap of planting time with these popular vegetable and herb staples.
