More details about Redwing Coated

The ultimate in a red-skinned storage onion, this one stores nearly as well as Copra. Sow Redwing storage onion seeds early to accommodate for its long days to maturity. The large, globe shaped bulbs are hard bodied, and uniform at 7-10cm (3-4") across. They have unique, deep red, glossy skins, and strong tops.

At the end of summer, when the onions have formed nice bulbs, harvest them as needed. At full maturity, the tops of the onions will fall over, signalling the end of growth and the time to harvest. If no rain or frost in forecast, knock each onion over the rest of the way. This will break the roots’ contact with the soil and begin the drying process. Leave the onions like that for two or three days.

At the first sign of rain or frost, bring the whole onion plants indoors and lay them out in a dry area away from direct sunlight. Leave them to cure for two to four weeks until there is no more green showing in the stems, leaves, or necks. During this time, the papery skins covering each bulb will harden and contract. Use scissors to trim off the roots, and cut around 2cm (1″) up the stem for each bulb. Store them in a cool, dark place in mesh bags or trays with breathing holes. A well cured storage onion can retain its desirable flavour and aroma for as long as 12 months.

These seeds are coated with an inert, organically certified layer which helps to minimize clumping in storage and seed sowing machines. The coating is approved by organic certifiers in Canada, the US, EU, and Japan.

All About Redwing Coated

Family: Amaryllidaceae

Difficulty

Difficulty
Scallions are easy to grow. Bulbing onions and shallots require transplanting in the spring and curing after harvest. By following these instructions, even novice gardeners should have no trouble.

Timing

Timing
Start shallots and storage onions indoors in late winter and early spring, and transplant 2-4 weeks after the last frost date. Overwintering onions need to be started in early summer, and transplanted by the middle of August. Scallions can be direct sown every 3 weeks from two weeks after the last frost date to late summer. Optimal soil temperature for germination: 21-25°C (70-75°F). Seeds will emerge in 6-12 days, depending on conditions.

Starting

Starting
Transplants are preferred for home gardeners. Sow 3 seeds 5mm-1cm (¼-½”) deep in each cell of a 72-cell tray. Transplant as a clump, spacing each 15cm (6″) apart in rows 45-75cm (18-30″) apart. Scallions can be spaced at 2-5cm (1-2″) apart in rows 15cm (6″) apart.

Days to Maturity:

Days to Maturity: From transplant date.

Growing

Growing
Ideal pH: 5.5-6.5 (6.0-6.8 for scallions). Fertile and well-drained soil in full sun is essential. Add well-rotted compost and dig ½-1 cup balanced organic fertilizer into the soil beneath each 3m (10′) of row. Keep moisture high in the top 20-30cm (8-12″) of soil. Most of the bulb should form on the surface of the soil, so don’t transplant too deeply. Bulb size is dependent on the size of the tops: the bigger the tops, the bigger the bulb. Provide August-planted scallions with the frost protection of a cloche or heavy row cover as the first frost date approaches.

Harvest

Harvest
Stop watering in the beginning of August to mature the bulbs in dry soil. After half the tops have fallen, push over the remainder, wait a week and lift the bulbs. Curing is essential for long storage: Spread bulbs out in a single layer in an airy spot out of direct sunlight. Once no more green is visible on any of the leaves, and they are dry and crisp, the onion is cured. If weather is poor, cure indoors. Storage: Keep onions in mesh sacks or hang in braids so they get good ventilation, and hang sacks where air is dry and very cool, but not freezing. Check them regularly and remove any sprouting or rotting onions. Well-cured storage onions should keep until late spring.

Seed Info

Seed Info
In optimal conditions at least 75% of seeds should germinate. Usual seed life: 1 year. Per 100′ row: 260 seeds (scallions 1.2M), per acre: 76M seeds (scallions 1,045M).

Diseases & Pests

Diseases & Pests
Botrytis blast and downy mildew are common leaf diseases. One starts with white spots and streaks, the other with purple-grey areas on leaves. Leaves wither from the top down and plants die prematurely. Separate the overwintered and spring crops because disease starts in older plants and moves to younger. Avoid overhead watering and plant in open sunny locations. Use lots of compost and practice strict sanitation and crop rotation.

Companion Planting

Companion Planting

The pungent odour of onions repels many pests and also protects nearby garden vegetables. Plant chamomile and summer savory near onions to improve their flavour. Onions also work well alongside beets, Brassicas, carrots, dill, kohlrabi, leeks, lettuce, strawberries and tomatoes. Don’t plant onions near asparagus, or peas of any kind.
