Description

1015Y Texas SuperSweet Onion is a large, yellow sweet onion with a slightly-flattened (granex) shape. This is one of the most popular short-day, sweet onion varieties for good reason. Although the maturity date is slightly longer than most short-day varieties, the size and taste of these onions are well worth it. The name is derived from the suggested time to plant this variety, October 15th. 1015Y was developed by Texas A&M University and produces sweet onions that average 1 lb and 4-5" in diameter. These onions will typically store for 2-3 months.

     

    Growing Information

    1015Y Texas SuperSweet 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. 1015Y Texas SuperSweet 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.
