To grow asparagus from seeds, soak the seeds in water for two hours, and fill 2-inch containers with potting soil. Plant the seeds 1/2-inch deep in the prepared containers, and maintain soil temperatures of 70 to 85 F until the seeds are transplanted. Transplant the seedlings to the garden after 10 to 12 weeks or after the last expected frost of the season. Allow the asparagus to grow for up to three years before harvesting it.Continue Reading
After planting the seeds, place the containers in a warm, bright location until the seedlings are transplanted outdoors. Prepare the garden for the asparagus by working 3 inches of organic matter into the soil. If necessary, amend the soil with lime to reach a pH of 6.5 to 7.
Plant the seedlings 12 to 18 inches apart along the edge of the garden or where the plants can grow for several years without disturbing them. During the first year of growth, fertilize the plants twice weekly.
Allow the asparagus to grow for two to three years before harvesting the stalks. To harvest asparagus, snap the stalks off at ground level when they reach 8 inches in height. Cut the brown foliage off the plant in the autumn, but do not disturb the bed to ensure the asparagus returns the following spring.Learn more about Gardening & Landscapes
