Candy Onion is a hybrid, day-neutral or intermediate-day onion variety that performs well in a wide-range of conditions. This onion variety will perform well in all regions with the exception of the deep south and the far north areas of the country. It produces a sweet, round bulb that is slightly flattened, but not as much as a typical granex or Vidalia variety. It matures relatively early and will store for months once harvested and cured correctly.
Candy Onion can be direct-seeded or transplanted, although we recommend transplanting. For direct-seeding, plant seeds 2″ apart along the row with a row spacing of 24″. Once seedlings emerge, thin seedlings to a 6″ plant spacing along the row. Candy Onion seeds can be planted with our Hoss Garden Seeder. We recommend using a #3 seed plate and modifying the hole size slightly to accommodate the onion variety being planted. For denser plantings, more holes may need to be drilled to accommodate a thicker spacing.
For transplanting, plant one seed per cell in our heavy-duty seed starting trays. Once the green stems reach 6-8″ in length and/or they can be easily pulled from the seed trays, the transplants are ready to go in the ground. Transplant onions 4-6″ apart along the row with a row spacing of 24″. If drip irrigation is used, onions may be planted on double rows with drip irrigation in the middle. We suggest burying the drip tape 3-4″ deep and planting on both sides of the tape.
Onions are heavy feeders and will require significant nutrient inputs throughout their lifespan. We recommend feeding them with our 20-20-20 and Ammonium Sulfate fertilizers. Fertilize with 20-20-20 shortly after transplanting. The phosphorous and potassium in the 20-20-20 fertilizer will help to promote solid root development, while the nitrogen will promote vegetative growth. Once transplants are established, we recommend side-dressing or injecting with our Ammonium Sulfate fertilizer. Side dress or inject 1 cup per 20 feet of linear row every 3-4 weeks after transplanting.

Onion Planting Guide
Select an onion variety based on your geographical location. In many cases, intermediate-day varieties can be grown in southern long-day regions and northern short-day regions.
- Plant in fall and overwinter for a spring harvest
- Start the bulbing process when day length reaches 10-12 hours
- Plant in late winter for an early summer harvest
- Start the bulbing process when day length reaches 12-14 hours
- Plant in spring for a mid-summer harvest
- Start the bulbing process when day length reaches 14-16 hours
