  • CERTIFIED ORGANIC ONION TRANSPLANT DETAILS: Our onion transplants are greenhouse grown on a small family farm & are dormant when shipped. It is normal for them to be pale & slightly dry due to dormancy & shipping. In fact, onions are very hardy & can live off of the bulb for approximately three weeks. Generally, we recommend planting within one week. These healthy transplants will thrive if well cared for. For your gardening success, we have switched from selling potted onion plants to onion transplants.
  • ONION SET DETAILS: We also have onion sets which are small pearl sized bulbs that are planted whole for a summer harvest.  Choose from yellow, red, or white onion sets.  Onion Sets can ship earlier, beginning in March.
  • LONG DAY & INTERMEDIATE DAY ONIONS: All of the varieties of our onion transplants & sets are either Long-Day or Intermediate-Day. 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: Onions prefer soil with a pH between 6.2 and 6.8. If your soil is too acidic, add ground limestone; if it is too alkaline, add peat moss. Adding compost or a balanced organic fertilizer is essential for growing healthy onions, especially if your soil fertility is low. For the best growth and yield, onions need fertilizer at planting time and additional side dressing.
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.
