Planting Instructions

Approx seeds per order 300

Plant onions in early spring to be harvested in the fall. They have long growing seasons and usually can withstand a light frost.

Start seeds indoors since they need a soil temperature around 50F to germinate. Once it gets warmer outside and the ground can be worked, transplant seedlings outdoors. Space transplants 4-6" apart in rows 12-18" apart. The plants will need about 1" of water per week. Onions are ready to harvest when the tops turn yellow and start to fall over.

Long Day vs. Short Day Onions:

This designation refers to the amount of daylight the onions need during the summer to form bulbs. Onions are sensitive to amounts of daylight and since different parts of the country receive different amounts of daylight during the summer, onions have been bred to accommodate that. An imaginary line was drawn across the United States, stretching from between the border of North and South Carolina to San Francisco. If you live south of that line, plant short day onions. And, if you live north of the line, plant long-day varieties. There are Day-Neutral or Intermediate varieties, as well, which can grow in any location.
