How To Grow Asparagus

Asparagus is a wonderful vegetable that can be grown in your backyard garden. It is a perennial plant that can produce for up to 20 years if grown properly. In this article, we will discuss how to grow asparagus and maintain it for a bountiful harvest.

Planting Asparagus

The first step in growing asparagus is to choose a good location. Asparagus requires full sun and well-drained soil. It is best to plant in early spring or fall. Before planting, make sure to remove any weeds or grass from the area. Dig a trench about 12 inches deep and 18 inches wide. Add compost or aged manure to the bottom of the trench to enrich the soil. Place the asparagus crowns in the trench about 18 inches apart and cover with 2-3 inches of soil.

Caring for Asparagus

Once the asparagus is planted, it is important to keep the soil moist but not waterlogged. Asparagus needs about 1 inch of water per week during the growing season. Mulching around the plants can help retain moisture and suppress weeds. As the asparagus grows, it will produce ferns that can grow up to 6 feet tall. It is important to leave these ferns in place until they turn yellow and die back in the fall. This allows the plant to store energy for the next growing season.

Harvesting Asparagus

It is important to not harvest asparagus in the first year after planting. This allows the plant to establish a strong root system. In the second year, you can harvest for about 2-3 weeks. Cut the spears at ground level when they are about 6-8 inches tall. Do not let the spears grow too tall before harvesting, as this can cause them to become tough and woody. In subsequent years, you can harvest for up to 8 weeks.

Pests and Diseases

Asparagus can be susceptible to pests and diseases. Common pests include asparagus beetles, slugs, and snails. These can be controlled with insecticides or by handpicking. Asparagus can also be affected by rust, which causes orange spots on the foliage. This can be controlled by removing infected foliage and applying fungicide.
