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.
