How to Grow Asparagus from Seed

Asparagus is a tasty and nutritious vegetable that can be easily grown in your own garden. While many gardeners choose to grow asparagus crowns, it is also possible to grow asparagus from seed. This article will guide you through the process of growing asparagus from seed, from seed selection to harvesting.

How to Grow Asparagus

Step 1: Seed Selection

The first step in growing asparagus from seed is to select the right seeds. Look for high-quality asparagus seeds from a reputable seed supplier. Choose a variety that is well-suited to your climate and soil conditions. It is also important to choose a variety that is disease-resistant and has good yield potential.

Step 2: Soil Preparation

Asparagus prefers well-drained soil that is rich in organic matter. Prepare the soil by removing any weeds and rocks, and then amend it with compost or well-rotted manure. Asparagus prefers a soil pH of 6.5 to 7.5. If your soil is too acidic, you can raise the pH by adding lime.

Step 3: Sowing Seeds

Sow asparagus seeds indoors in late winter or early spring. Fill a seed tray with a good quality seed starting mix, and then sprinkle the seeds on top. Cover the seeds lightly with soil, and then water well. Keep the soil moist but not soggy, and provide bright, indirect light. The seeds should germinate in 2–4 weeks.

Step 4: Transplanting

After the seedlings have developed two true leaves, it is time to transplant them into individual pots. Choose pots that are at least 4 inches in diameter and filled with a good quality potting mix. Gently remove the seedlings from the seed tray and plant them in the pots, burying the stems up to the first set of leaves. Water well, and then place the pots in a warm, bright location.

Step 5: Hardening Off

As the weather warms up, it is important to harden off the seedlings before transplanting them into the garden. Start by placing the pots outside in a sheltered location for a few hours each day, gradually increasing the amount of time they spend outside. After a week or two, the seedlings should be ready to transplant.

Step 6: Transplanting into the Garden

Transplant the seedlings into the garden in early to mid-spring, when the soil has warmed up and the danger of frost has passed. Dig a trench that is 6–8 inches deep and 12–18 inches wide, and then add a layer of compost or well-rotted manure to the bottom of the trench. Space the seedlings 12–18 inches apart, and then cover the roots with soil. Water well, and then add a layer of mulch to help retain moisture.

Step 7: Care and Maintenance

Asparagus requires regular watering, especially during dry spells. Keep the soil moist but not waterlogged, as asparagus does not tolerate wet feet. Fertilize the plants in early spring and again in mid-summer with a balanced fertilizer. Asparagus can also benefit from a side-dressing of compost or well-rotted manure in mid-summer.

Step 8: Harvesting

Asparagus can be harvested in its second or third year of growth, depending on the variety. Cut the spears when they are 6–8 inches tall and still tightly closed. Cut the spears at ground level using a sharp knife, being careful not to damage the developing spears. Harvesting should continue for 4–6 weeks, or until the spears become thin and woody.

Growing asparagus from seed is a rewarding and satisfying experience. With proper care and maintenance, you can enjoy a bountiful harvest of delicious asparagus for years to come. Remember to choose high-quality seeds, prepare the soil well, and provide the proper care and maintenance for your asparagus plants. With a little bit of patience and hard work, you’ll be enjoying the fruits of your labor in no time.
