ON591 Patterson F1 Storage Onion seeds

Product Details

This fantastic long day storage onion replaced the much-loved Copra. Patterson onion seeds produce round, firm, uniform bulbs that store exceptionally well through the winter in the right conditions. The bulbs are medium to large in size with thin necks that dry down quickly. The firm flesh has well defined layers (rings) and nice pungent flavour. This is probably the best storage onion for southern and central Canada and the northern US.

These seeds may be 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.

Quick Facts:

    • Exceptionally long-storing
    • High yielding
    • Long day type

All About Patterson F1

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.
