Territorial Seed Company Texas Supersweet 1015Y Onion Plants

Short-day onions are triggered to begin forming bulbs when day length reaches 10 to 12 hours. They are specifically bred to thrive in southern latitudes where these day lengths occur earlier in the spring.

While these are best suited for southern regions, you can grow them in the north by planting them as early as possible in the spring. Keep in mind that they may not reach their full potential size compared to those grown in their ideal southern environment.

Onions prefer loose, well-draining sandy or loamy soil with a pH between 6.0 and 7.0. Ensure the soil is rich in organic matter and free of large rocks or debris to allow the bulbs to expand to their full size.

Once transplanted into your garden, the 1015Y typically reaches maturity in 100 to 115 days. You can expect to harvest your onions in late spring or early summer.

The 1015Y variety offers better storage qualities than many other grano-type onions. While they are known for their sweet, mild flavor, they will keep well for a reasonable period if stored in a cool, dry, and well-ventilated location.

The plants are shipped hardened-off and ready for your garden. It is best to plant them as soon as possible after they arrive to ensure they establish their root systems quickly.
