Allium tricoccum, wild leek and ramp are all names for a tasty, edible plant that is a close relative of the onion. Its bulb is often substituted for onions and scallions in recipes. Its leaves and flowers may also be eaten and make an interesting addition to salads. The best time to transplant Allium tricoccum is in early spring at the beginning of its growing season. Planting large bulbs (more than 1/2 inch in diameter) can provide ramps that you can harvest in two to three years.
Choose an ideal location to transplant your Allium tricoccum. In the wild, these plants grow under the canopy of beech, birch, sugar maple or poplar trees. If you do not have such a naturally shaded area under which to plant your wild leeks, purchase and erect a netted or woven shade structure over the new planting area.
Dig the Allium tricoccum from their current location. Use a spade to loosen the soil a few inches on either side of each bulb. Then grab the plant at the base of its stem and gently pull it out of the soil.
Brush the excess dirt off of the bulbs, and then check them for damage. Any insect-eaten or otherwise damaged Allium tricoccum bulbs should be discarded.
Prepare the new planting area. Use a hand tiller or rototiller to loosen the soil to a depth of 4 inches. Remove any rocks, debris, plants or roots from the area, and break up any large clumps of soil. Then spread a 3-inch layer of aged organic compost over the planting area. Finally, till the soil again to a depth of 8 inches and smooth the planting area with a rake.
Dig holes in the new location. Each hole should be just as deep as the bulb is long. When planted, the top of the bulb should peek above the surface of the soil. Neighboring bulbs should be at least 4 inches away.
Plant the Allium tricoccum in their new holes. Remember to leave the tips of the bulbs above the soil. Then gently pat the soil down with your hands to firm the soil.
Spread a 2-inch layer of organic mulch around but not directly over the Allium tricoccum. This mulch controls weeds, fertilizes the soil and keeps it at a constant temperature. Hardwood leaves are the best mulch for these forest plants, and agricultural researchers at the University of North Carolina assert that bark mulch and commercial mulches are ineffective.
Water the planting area so that the soil is quite moist but not soaked enough to form puddles. Continue to keep the soil moist throughout the growing season. Allium tricoccum requires moist soil to grow.
