Onion Texas 1015Y


Texas 1015y

Sweet Onion Seeds

Allium cepa
(OP) 110 days

Painstakingly developed in the 80s by Leonard Pike at Texas A&M University, and named for their ideal October 15 planting date in Texas, this flattened, yellow-skinned onion with rounded shoulders is perfect for hot summer climates.

Texas 1015Y is unusually mild and sweet, disease-resistant, good for storage when cured, and can weight over 1 pound. If you live in a northern climate, try Walla Walla.

Growing Texas 1015y Onion Seeds

Bee introduces how to plant

Plant Onion Seeds: Direct sow ½ in. deep, 2-4 seeds per inch, in rows 12-24 in. apart. Kept at 55-75°F., germination is in 7 to 15 days. Sweet Onions: Thin to 2 to 4 in. between plants. Bunching Onions: Thinning is not necessary unless you want an extra large diameter.

Harvest Sweet Onion: When stalks begin to fall over, pull onions out of the ground and sun dry for several days, then store in a cool, dry, dark location.

Harvest Bunching Onion: Bunching onions store very well in the ground, and can be harvested as needed over a long period.
