How To Grow Asparagus: Plant It Once & Harvest For Decades

Growing your own fruit and veggies is sometimes challenging, but we strongly suggest that you grow asparagus (Asparagus officinalis) in your home garden. It’s a perennial plant that produces high yield for three decades.

The asparagus plant looks really good, and it will make your garden look even more beautiful.

Asparagus is native to Western Europe, and it grows really well in cold or dry areas. It doesn’t thrive in Florida and the Gulf Coast because of all the moisture and high temperatures. Plant asparagus if you live in the USDA planting zones 2-8.

Grow asparagus from seeds

Start the seeds inside or in your greenhouse in mid-February to May. Asparagus seeds germinate under great light and soil temperatures between 70 and 85 degrees. Soak the seeds for 2 hours before the planting process.

How to plant the seeds?

Fill 3.5-inch pots with soil and place 2 seeds on the surface of the soil. Add a thin layer of sifted sand. Bottom watering works best. Keep the pots on a heated table to keep them warm. The soil should never dry out.

The seedlings should grow for 3 months. Transfer them when the weather gets warm. Plant the seedlings about 18 inches apart of rows that are 4 inches apart.

If your spears are thinner, keep them at 8-10 inches apart and 4 inches deep. If your spears are thicker, keep them at 12-14 inches apart and 6-8 inches deep. Cover the seedlings with soil. They need about an inch of water every week.

You can harvest the plant after three years. Let the plants grow in summer, and then trim it down to 2 inches in fall.

Grow asparagus from crowns

First, prepare your bed. Asparagus plants like sandy and loose soil with neutral pH values. The soil has to drain well too. If you combine asparagus with other veggies, keep it in the north or west side of the garden so it doesn’t shade other vegetables.

Add compost into the soil. Make 12-inch deep furrows in the bed. Add a cup of organic fertilizer in each furrow. Put loose dirt into cone-shaped piles about 6 inches tall at the bottom of each furrow. Leave 18 inches between the cones.

Place the asparagus crown on top of the dirt pile. Let the roots hang down over the dirt pile. Add a 1-inch layer of soil. The soil has to be moist all the time. Don’t overwater it though.

Remove any weeds, and add more soil as the plant grows. Keep doing this until the furrows are filled to ground level with the soil. Let the plant grow for 2 years.

Tips for higher yield

Asparagus grows well near tomatoes, and repels nematodes. Tomatoes repel asparagus beetles. Harvest your asparagus for four weeks in year three and for 6-8 weeks in year four.

Plant all-male varieties to get bigger yield. Mulch suppresses weeds. Soak crowns in compost tea before the planting process to give the plant enough energy.

Give the plant enough time to grow after the harvesting. Wait until the foliage turns yellow/brown, and cut the plant to 2 inches. Fertilize the crowns in spring and fall. Your fertilizer needs to contain fish, seaweed, and kitchen scraps. Use rock phosphate to trenches each year before planting new crowns.

Harvest and store your asparagus

Cut off spring shoots when they grow about 8 inches. Cut the plant below the soil line. Avoid plants that have developed foliage. Harvest your asparagus every other day. Asparagus plants produce from 2 to 8 weeks.

Harvest asparagus until the spear diameter reaches the size of a pencil.

Keep fresh asparagus in your fridge for a week. If you like to freeze it, make sure you blanch it for five minutes. Dry it and store it in freezer bags.
