Ramps

seeds
Allium tricoccum
(6-18 months) Open-pollinated. Also called Wild Leeks. This bulb-forming perennial is a spring ephemeral. Their rapid rise as the darling of top chefs has led to overharvesting. Now considered a species of “special concern” for conservation in Maine and other states; in Québec commercial harvesting is banned. With patience and care you can sustainably grow and harvest your own woodland crop. Delectable pungent flavor, a mix of garlic and onion, is true wildwood fare—worth the long wait. Not a good germinator, often with latent dormancy; expect less than 50%.

Additional Information

Ramps

Culture: Ramps are a native perennial of deciduous forests, growing best in cool shady areas with damp rich soil high in organic matter and calcium. An open-field setting is probably too dry and exposed for good germination, and the plants do not have a long life in artificial shade. Because this is a wild plant, seed planted in the spring will germinate that spring if conditions are right; if not, it may germinate the next spring. Mark your patches well and provide protection from predation. Once a bulb is formed, the new leaves emerge in early spring, before the tree canopy develops; by late spring leaves die back and a flower stalk emerges. Photosynthetic period and the harvest window is limited to these few weeks. Once established, ramps grow in close communities, strongly rooted just beneath the soil surface. Harvest carefully with a sharp knife, cutting plants just above the roots. Disturb roots as little as possible.

Onions

  • About 200-250 seeds/g, 5,700-7,000 seeds/oz.
  • Days to maturity are from transplant date.

Culture: Set seedlings out 1–2" deep and 6–8" apart in shallow trenches, 1–2' between rows. Onions survive light frosts. 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. In the event of extreme heat or prolonged damp conditions, we recommend sheltered curing in a well-ventilated barn or greenhouse. Curing is essential for long storage. Store cured onions in mesh sacks in a cool dry well-ventilated place, periodically removing sprouting or rotting bulbs. In spring, put your remaining onions in the fridge to extend storage until your new crop is ready.

Onions are triggered to form bulbs in response to day length. Day length differs depending on latitude, so different onion varieties were developed to have different day-length needs. In the north, the earlier onions are set out, the more chance they have to make top growth while the days are lengthening. High fertility and steady water is crucial for large onions. Side dressing is recommended. After summer solstice they begin bulbing.

All the varieties we list are suitable for northern growers. If you live farther south, note our latitude specifications at the end of each description.

Long-day: Must be north of 36° latitude, though some long-day types perform best north of 40°. These onions need 14-16 hours of sun a day to trigger bulb formation. May not perform well in continually hot soil temps.

Intermediate-day: Also called day-neutral onions, generally need 12-15 hours of daylight to bulb. Some can do well in parts of the upper southern U.S. all the way up through Maine. Others are best for mid-latitudes only (35-40°). All intermediate-day onions in our catalog have performed well repeatedly in our Maine trials.

(Short-day: Suited for the South, below latitude 36°, bulbing when the day length measures between 10–12 hours. We don’t offer seed for short-day varieties.)

Onion seed is short-lived. Retest 1-year-old seed before using. Discard anything older.

Alliums

Culture: Start allium seeds indoors in February or March. Minimum germination soil temperature 45°; optimal range 60-70 °. We discourage using bottom heat because alliums germinate poorly in soil temps above 70°. Transplant in spring soon after the ground can be worked.

Alliums are heavy feeders and want generous amounts of organic matter, fertilizer and water. Late transplanting and poor fertility can result in small onions or failure to form bulbs. Alliums are notoriously intolerant of weeds. Slugs love to munch them, and in areas above 40° latitude, root maggots may be a problem.

About allium seed: Allium seed is short-lived. We do not hold over hybrid onion seed because of precipitous decreases in germination. Test 1-year-old seed before using. Discard anything older.

Diseases:
DM Downy Mildew
PR Pink Root

ALERT: Leek Moth is emerging as a serious pest potentially affecting all Alliums in the Northeast. Consult your local Cooperative Extension for more info.
