Be sure to check out our Onion Growing Guide for helpful tips & tricks on how to successfully grow onions in your garden. 

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.

Growing Information

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.

Onion Planting Guide

Select an onion variety based on your geographical location. In many cases, intermediate-day varieties can be grown in southern long-day regions and northern short-day regions.

Short-day Onions

Plant in fall and overwinter for a spring harvest

Start the bulbing process when day length reaches 10-12 hours

Intermediate-day Onions

Plant in late winter for an early summer harvest

Start the bulbing process when day length reaches 12-14 hours

Long-day Onions

Plant in spring for a mid-summer harvest

Start the bulbing process when day length reaches 14-16 hours

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.

Best Onions I’ve Grown

After years of growing Texas 1015 and Texas Legend with mediocre results, I decided to give Cougar a try and I’ll never go back. I got consistent jumbo sized onions with a great flavor and no bolting at all. After a good cure, they lasted a solid 5 months before we put the rest up in the freezer. I’ll never plant onions again without Cougar as my backup plan.
