Cougar Onion is a hybrid, short-day onion with a light brown coloration on the outer skin. This is a sweet onion variety that produces round, globe-shaped onions. This variety produces massive onions with sizes ranging from jumbo to colossal. This is a great variety for raw preparations or cooking. The round shape makes it easier to cut and prepare than some of the flatter, granex varieties.

Cougar 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. Plethora 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 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.
