How to Sow Asparagus With Seed

Overview

Asparagus stalks grow on hardy garden perennials, so once you establish your asparagus patch you won't need to replant it. Growing asparagus from seed takes a couple of seasons. The first step is sowing the seed and allowing the plants to grow for one year. In the second year, the plants are transplanted. Ohio State University recommends choosing male asparagus cultivars, since they outperform the female varieties by 3-to-1.

Step 1

Test your soil with a pH kit. Asparagus prefers a pH of 6.5 to 7.5 and will not grow well in soils with a pH lower than 6.0. To use a home kit, collect soil and moisten it. Then drop the pH strip on the moist soil and wait for it to change color. Check the color's corresponding pH value on the enclosed chart. Amend a soil by adding lime to raise the pH or acid to lower it.

Step 2

Wait until frost danger has passed for your area. Soak your asparagus seeds the night before planting in a jar of lukewarm water.

Step 3

Prepare the bed for planting the next day. Turn over the soil with a shovel to aerate it and break apart any roots with a small trowel or rake. Remove rocks, weeds and sticks from the site.

Step 4

Create a 1/2-inch deep furrow for your asparagus seed using your small trowel.

Step 5

Sow your asparagus seed into the prepared furrow, spacing one seed every 2 to 3 inches. Water the area until the soil becomes moist but not wet.

Step 6

Continue to water your newly planted asparagus seeds so that the soil is always moist but not boggy. The seedlings should germinate in three to six weeks and you'll be on your way to growing your own asparagus spears.
