Description

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

Cirrus Onion is a hybrid, short-day variety with consistent yields of high-quality white onions. This variety produces medium-sized, slightly-flattened onions. Plants produce a significant amount of foliage which may require a wider plant spacing. These onions have an attractive appearance and are great for slicing and using raw for topping your favorite grilled treats.

Growing Information

Cirrus 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. Sterling 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.

I like this onion

I have planted these onions from seeds for 2 or 3 years now. Compared to the other onion seeds I've tried, these Cirrus seeds have germinated well, the plants are healthy, and these have definitely performed the most consistently when transplanted outside into the raised beds. The onions are not huge but the size is perfect to slice one or two over a salad or use in an individual dish.

Cirrus Onion, not good

Only had approx 30% germination. All other varieties I planted are near 90-95%. Not sure what the deal is with this variety. I will continue to buy from Hoss, they try hard to satisfy their customers.
