Red Mountain Red Storage Onion


Red Mountain Red Storage Onion

(107 days) F-1 hybrid. When we heard from breeder Bejo that Redwing’s boots would soon walk out the door, finding a replacement looked like a tough climb. But, our 2018 and 2019 storage onion trial turned out to be an easy stroll up Red Mountain. Also from Bejo Seeds, Red Mountain brings the same large 16–18 oz glossy deep red globes as Redwing, but it sizes more consistently regardless of dry or wet conditions. Red Mountain’s neck “sit down” in the field 10 days earlier than Redwing, aiding harvest in unpredictable fall weather. The earlier harvest sacrifices nothing in curing and storage, as Red Mountain keeps like a rock through April with succulent texture and balanced mild sweet onion flavor. When we cooked it after long storage, we thought the bulb and ring of Red Mountain had better color than Redwing. Adapted to 43–65˚ latitudes. Resistant to PR. NEW!

Allium cepa

Days to maturity are from date of transplanting.

Culture: Start indoors in Feb. or March and transplant out in spring almost as soon as the ground can be worked. Set 4–6" apart in trenches in well-dug beds with generous quantities of organic matter. Avoid transplanting next to grass strips; slugs love to dine on tiny allium seedlings. Irrigate seedlings whenever the topsoil dries out.

Onions are day-length sensitive. Long-day types are for northern latitudes. The earlier they are set out, the more chance they have to make top growth while the days are lengthening. The more top growth, the greater the bulb size. After summer solstice they begin bulbing.

After half the onion tops fall, push over the remainder and harvest within a week. Field-cure in the sun about 10 days until dry, covering with a tarp in wet weather. Curing is essential for long storage. Hang sacks in a cool dry well-ventilated place, periodically removing sprouting or rotting bulbs. Onions survive light frosts. When it begins to warm up in spring, put your remaining storage onions in your refrigerator crisper. Most will keep without sprouting until your new crop is ready.

Minimum germination temperature 50°, optimum range 60-70°. We discourage the use of bottom heat because onions germinate poorly in temperatures above 70°.

We do not hold over hybrid onion seed because of precipitous decreases in germination. Onion seed is short-lived. Retest 1-year-old seed before using. Discard anything older.
