Delightful and Delicious Red Karmen Onion

  • 80 Days to Maturity
  • Beautiful Purple Flesh
  • Ideal Red Onion
  • Well-Balanced Sweet and Spicy

When you know onions, you spell flavor "R-e-d K-a-r-m-e-n." Red Karmen Onions make some of the best sliced onion for burgers, salads, sandwiches, and pizza. They have a perfectly balanced sweetness with only a hint of spice and unbelievable crunch. And, of course, Red Karmens add a pop of red-violet to any dish in need of color.

These easy to grow onions are a favorite for beginner gardeners and experts alike. Plant them early in the cool spring weather, as soon as your soil can be worked. They thrive in full sun and prefer well-drained soil. Simply till or fluff your soil then plant your onions a few inches apart. Water them regularly and as needed to keep the plants stress free.

The onion tops will grow quickly in the cool weather and the bulbs will develop below ground. If you planted them too close together, you can simply pull out any that are too close and use them as green onions or spring onions and leave the ones spaced out better to develop large bulbs.

It is best to wait to harvest the large onions until their foliage browns. Once their tops wilt and turn brown, it's time to harvest your sweet, stunning onions. Locate the onions beneath the dried foliage, then gently pry them out with a spade or spading fork. You can let them sit on top of the soil in the sun for a few days to help dry the roots down before tying the tops together in bunches and hang them to dry in your garage to hand for a while. Then store until you're ready to eat them.

You can expect your Red Karmen Onions to be even in size and ripen in about 80 days after planting. This onion will develop into plump globes and are slightly ovular and will be ready to harvest in late spring or summer depending upon when you planted them. This vigorous grower can also be used as scallions.

The deep-red onions store because of their thick outer skin and show superior resistance to downy mildew.

Reserve a space in your veggie garden for your own Red Karmen Onions. These crisp but juicy onions will add some zest to your spring and flavor to your favorite dishes. Don't wait to order. These bright and bold onions are guaranteed to sell out.
