Growing Asparagus

Asparagus, also called garden asparagus and sparrow grass, is a traditional vegetable plant belonging to the Asparagaceae family. It was initially found in southern Asia and the eastern Mediterranean. Asparagus is a popular vegetable because of its juicy, tender spears and distinct, mild flavor. There are various ways to use it in the kitchen as well.

An asparagus crown is a fully developed root system typically one or two years old. It comprises a central rhizome from which several buds and roots grow. When planted in soil, these crowns grow into fully asparagus plants. It is better to grow asparagus from crowns than seeds since it will be harvested sooner.

Types of Asparagus

These three varieties of asparagus are versatile and nutritious additions to meals. They have distinct flavors and culinary uses.

The most popular type of asparagus is green, found in home gardens and food stores. When exposed to sunlight, it naturally grows and produces chlorophyll, which gives it its vibrant green color. Its texture is tender but slightly fibrous, and its earthy and grassy flavor. Asparagus is frequently used in salads, stir-fries, grilling, and roasting and is rich in vitamins A, C, and K.

Growing white asparagus involves protecting the plants with soil or transparent plastic from sunlight, which stops chlorophyll from forming. In contrast to green asparagus, the stalks retain their pale color and taste milder and slightly sweeter. White asparagus is frequently served with sauce or butter in European cuisine, particularly in Germany and France. Because of its more fibrous texture, it needs to be peeled before cooking.

High concentrations of antioxidants called anthocyanins give this variety its eye-catching deep purple shade. Compared to green and white asparagus, it is usually sweeter and softer, which makes it perfect for salads or mild cooking. However, its purple color frequently turns green when cooked.

Purple asparagus tastes slightly nutty, has a more delicate bite, and has fewer fibrous strands. It is less common than green asparagus but is becoming more popular.

Grow Guide of Asparagus from Crowns

Here is a guide to grow and enjoy the tasty flavors of asparagus from its crowns:

1. Area Preparation

Before cultivation, it is essential to select a variety that is compatible with the environment and tastes. As asparagus is a long-term crop, choosing the ideal location and properly preparing the soil are also critical to its success.

Select an area that receives at least six to eight hours of sunlight daily. Asparagus roots may decay in moist conditions, so ensure the soil drains properly. Avoid planting asparagus in areas once used for potatoes, onions, or garlic to prevent diseases.

Asparagus grows best in loamy, sandy, or well-draining soil with a pH of 6.5 to 7.5. Before planting, mix in compost or well-rotted manure to add additional nutrients. Remove large stones and invasive plants to create a smooth planting bed.

2. Plantation

Early spring is the best time to plant asparagus crowns because the soil is ready for growth. Build a trench 6 to 8 inches deep and 12 to 18 inches wide. The trenches should be 3 to 4 feet away to encourage healthy root development. 

Spread the asparagus roots like a starfish and place the crowns in the trench. Place them at a 12 to 18 inches distance to allow the crowns to grow. Cover the tops of the crowns with 2 to 3 inches of soil. Gradually add more soil to the trench as the plants reach ground level.

3. Irrigation

Avoid overwatering when irrigating newly planted crowns. The soil should be moist but not saturated. Place a layer of mulch such as wood chips, straw, or leaves to keep moisture in and suppress unwanted plants.
