Growing Information

Bella Luna 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. Onion seeds can be planted with our Hoss Garden Seeder. We recommend using a #1 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 Calcium Nitrate 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 Calcium Nitrate fertilizer. Side dress or inject 1 cup per 20 feet of linear row every 3-4 weeks after transplanting.

No trouble to grow over winter in Florida and excellent storage quality. They were fine at eight months when we ran out. Next year I'll grow a lot more than fifty.

I will grow these every year. They have great seedling vigor, are easy to start in flats, and transplant well. They survived the Arctic Blast in zone 9a without covering with no ill effects. They produce mainly 4 to 5 inch bulbs, but best of all is the taste. The best onion I have grown or eaten.
