All About Asparagus

Asparagus is a delicious vegetable that is relatively easy to grow. There are several considerations to take into account when growing asparagus including where to plant, when to harvest, and some mistakes to avoid. 

How to Plant Asparagus:

Choose a location: Asparagus grows best in well-draining soil that receives full sun or partial shade. Select a spot in your garden that meets these criteria and has enough space for your asparagus to grow, as it will spread out over time.

Prepare the soil: Loosen the soil to a depth of at least 12 inches. Remove any rocks, roots, or weeds from the area. Add compost or other organic matter to the soil and mix it in thoroughly. Fertilizers can also be added when planting.

Plant the crowns: Dig a trench 8-10 inches deep and 12-18 inches wide. Place the crowns on the raised pyramid in the trench and keep the crowns 2 inches below the soil line. Pant asparagus about 12-18 inches apart. Cover the crowns with 2-3 inches of soil and water thoroughly. 

Water the soil: Water the soil thoroughly after planting to ensure that the asparagus roots are well-established. Asparagus requires regular watering, so make sure the soil remains moist but not waterlogged.

Mulch the soil: Add a layer of mulch to help retain moisture in the soil and suppress weeds. Use straw, leaves, or other organic materials for mulch.

How to Harvest Asparagus:

You’ve planted your asparagus and the following spring they have started growing. Before you harvest the asparagus, there are some things you need to know. 

In year one, don't pick any asparagus and let them grow to full size the first year. In year two you can harvest about half of what grows so the other half can help establish the root systems. In year three, all asparagus can be harvested up until late May into early June. 

Harvest Asparagus when they are about 6-8 inches tall. Use a sharp knife to cut them off at the soil line and enjoy! 

Asparagus can be fast growing in the springtime and mature plants should be checked every day so that they plants don't get too big for eating.

Asparagus Mistakes to Avoid

One thing to consider before planting asparagus is considering how tall the plants will get. After the harvest season, the plants will mature and grow to several feet tall and produce seeds. It is important to have them planted in an area that can accommodate the height of the plant that won’t shade out other parts of the garden. Asparagus beds can last for years so picking the best location is crucial before planting.
