I love asparagus and it was one of the first plants that I grew in my backyard. With the right tips and techniques, I was able to grow the plant easily and am still enjoying it after 3 years. In this article, you will learn everything about growing asparagus.

Everything You Need to Know About Asparagus

Asparagus is one of the few perennial vegetables that can be easily grown in a garden. It is also the first vegetable that is ready to be harvested during spring. Once it has established, it will continue to give you a crop for more than 20 years. This makes it a great investment that will continue to give you returns for many years.

The asparagus plant will remain in the same place for many years. Therefore, it is important to find a spot that offers the spears all the growing conditions it requires to develop a good crop each year. The plant takes around three years to fully mature and fill in. However, it is worth the wait. Once the root system has developed, you will be able to harvest asparagus spears for many years.

Learn How to Plant and Grow Asparagus

The first step to growing spears is finding a plating site. You need to pick the right location and then prepare the soil correctly so that the plant grows well. Choose a location that receives at least 8 hours of full sun each day. While the spears can tolerate and grow in partial shade, a sunny location is best.

Preparing the Planting Site

You need a well-drained, loose, and fertile soil to plant asparagus. Since this plant has a crop cycle fo more than 20 years, you need to fill asparagus bed with nutrients right from the start. When you are planting, work in a generous amount of compost. It will help improve the structure and fertility of the soil you are going to use for planting. For best results, use a 5 gallons bucket of compost for every 5 sq ft. of planting space.

Selecting Your Plants

Asparagus plants have two types: male and female. Male varieties are usually the preferred choice when the plant is being grown in gardens. Male plants have a higher rate of spear production and also grow bigger than female plants. There are many varieties of male asparagus plants that you can choose from. The most common ones include Jersey Giant, Jersey Knight, and Purple Asparagus. These varieties are not only heavy producers but also come with an outstanding flavor. This is why most people prefer these to other varieties.

Crowns or Seeds?

Asparagus can be grown from crowns or seeds. If you are looking for an easier and better choice, then go for asparagus crowns. Asparagus crowns are actually roots of 1-2 years old asparagus plants ( These are the best option if you want to grow an edible crop quicker. With crowns, you can get an earlier harvest, and maintaining an asparagus bed is also easy.

Seeds, on the other hand, are difficult to plant and are often affected by weeds. They also give a much smaller crop as compared to the crowns.

Planting Asparagus

The best way to plant asparagus is by using the trench method. Start by digging a 6″ deep and 8″ wide trench in the soil. Place the crowns at the bottom of the trench. Put in some water and cover the trench with a 2″ layer of topsoil. Make sure that there is a gap of 18″ between crowns and 12″ between each row (

Keep adding more soil as the crown keeps growing through the soil. Fill in the trench slowly with soil. It will take a couple of weeks to fill the trench completely with soil. This process will allow the roots to develop a deep root system which is essential for getting excellent crop harvests over the years.

Maintaining Asparagus Crop

The biggest key to keeping your asparagus crop growing successfully is to keep the beds free from weeds. Grass and weed compete with each other for valuable nutrients. Thus, an asparagus bed full of weed will lead to less productive harvests. To prevent the growth of weeds, keep the beds covered with a thick layer of mulch. This will suppress the production of weeds (

Other than preventing the growth of weeds, there is little maintenance that the plants need. Once the plants and the root system has established, the beds will continue to give you a tasty crop over the years.
