Onion Set Sampler

Naturally Grown Onion Set Sampler

ONION SETS- Alternatively, we also offer naturally grown onion sets. These Non-GMO, Non-Treated, small pearl sized bulbs are planted whole for a summer harvest. Choose from yellow, red, or white onion sets.  Onion Sets can ship earlier than our plants, beginning in March.

LONG DAY & INTERMEDIATE DAY ONIONS

    • All of the varieties of onion plants & sets we offer are either Long-Day or Intermediate-Day onions. They are adapted best for latitudes as far north as Maine to as far south as Northern Texas, depending on the variety. Our onions are not adapted for Short-Day regions.

BASIC ONION GROWING INFO

  • Sun Requirement: Onions require full sun – the more the better! Therefore, avoid planting next to crops that might shade your onions.
  • Soil Fertility: Adding compost or a balanced organic fertilizer is essential for growing healthy onions, especially if soil fertility is low. For the best growth and yield, onions need fertilizer at planting time and additional side dressing throughout the growing season.
  • Planting: Onions grow best on raised beds or raised rows at least 4″ high. Typically, onions can be planted as early as 4 to 6 weeks before the last estimated spring frost.
