How to Grow Asparagus: A Step-by-Step Guide

Asparagus is a delicious and versatile vegetable that can be enjoyed in a variety of dishes. It is also a relatively easy crop to grow, making it a great option for home gardeners.

Here is a step-by-step guide on how to grow asparagus straight out of the Ace’s Garden How To Handbook:

Choose a Planting Location

When it comes to cultivating asparagus, choosing the right location is crucial for the success of your crop. Asparagus is a perennial vegetable that requires specific environmental conditions to thrive and produce a bountiful harvest. Ace explores the key factors to consider when selecting a location for growing asparagus, ensuring that you create an ideal environment for this delicious and nutritious vegetable.

Asparagus thrives in full sun, so selecting a location with maximum sunlight exposure is essential. Choose a site that receives at least 8 hours of direct sunlight per day. Adequate sunlight promotes strong growth and photosynthesis, which are vital for healthy asparagus ferns and robust spear production.

Asparagus ferns are tall and slender, making them vulnerable to wind damage. Planting asparagus in a location shielded from strong winds will prevent breakage and ensure healthy growth. Natural windbreaks like trees, hedges, or fences can provide effective protection. If your chosen site lacks natural wind barriers, consider creating artificial structures to shield the asparagus patch.

Asparagus is a cool-season crop that requires a period of winter dormancy to stimulate spear production in spring. Choose a location with a moderate climate that experiences distinct seasons. The plant can withstand light frost, but extended exposure to freezing temperatures can damage or kill the crowns. Consider local climate patterns and choose a site that minimizes the risk of late spring frosts, as these can harm emerging spears.

Prepare the Soil

Amend the soil with compost or manure to improve drainage and fertility. Creating a suitable soil environment is crucial when it comes to cultivating asparagus. As a perennial vegetable, asparagus requires a well-prepared bed that provides the right nutrients, drainage, and structure for its long-term growth and productivity.

Asparagus thrives in well-drained soil that is rich in organic matter. If your soil lacks these qualities, amendments can be added to improve its structure and fertility. Incorporate compost, well-rotted manure, or other organic matter into the top 12 to 18 inches of soil. This addition will enhance drainage, increase water-holding capacity, and provide essential nutrients for healthy asparagus growth.

Asparagus plants require a deep and spacious bed to accommodate their extensive root systems. Dig trenches that are approximately 12 inches wide and 6 to 8 inches deep. Space the trenches about 4 to 5 feet apart to allow adequate room for mature asparagus plants to develop. The trenches will serve as the designated planting area for your asparagus crowns.

Once the trenches are prepared, it is beneficial to incorporate a balanced organic fertilizer or a specifically formulated asparagus fertilizer into the soil. Follow the manufacturer’s instructions for application rates and methods. This step ensures that your asparagus plants receive an initial nutrient boost, setting them up for healthy growth and spear production.

Plant the Asparagus Crowns

Asparagus crowns are the best way to start growing asparagus from scratch. They are the roots of mature asparagus plants, and they come ready to plant.

To plant asparagus crowns, you will need:

  • Asparagus crowns
  • A shovel
  • A garden hose
  • Mulch

Instructions on planting asparagus crowns:

  1. Choose a planting location. Asparagus prefers full sun, but it can tolerate some partial shade. The soil should be well-drained and fertile.
  2. Prepare the soil. Amend the soil with compost or manure to improve drainage and fertility.
  3. Dig a trench. The trench should be 12 inches wide and 6-8 inches deep.
  4. Add a layer of compost or manure to the bottom of the trench.
  5. Place the asparagus crowns in the trench, spacing them 18 inches apart.
  6. Cover the crowns with soil, leaving the tips of the crowns exposed.
  7. Water the crowns well.
  8. Mulch around the crowns with straw or shredded bark to help suppress weeds and retain moisture.

Asparagus Planting Tips:

  • Soak the asparagus crowns in water for several hours or overnight before planting. This will help them to establish themselves more quickly.
  • Do not harvest any spears from the asparagus crowns for the first two years. This allows the plants to mature and produce more spears in the future.
  • Water the asparagus crowns regularly, especially during dry periods.
  • Mulch the asparagus crowns annually to suppress weeds and retain moisture.
  • Fertilize the asparagus crowns in the fall with a balanced fertilizer.

With proper care, your asparagus crowns will thrive and produce delicious spears for many years to come. To compliment your asparagus, try pairing with fresh peas. When you finish Ace’s guide on how to grow asparagus, check out his guide on How To Grow Peas.

Water the Asparagus Well

Asparagus is a relatively drought-tolerant plant, but it does need regular watering, especially during the first two years after planting. Once the plants are established, they will need less water.

When to Water Asparagus

  • During the first two years, water the asparagus plants deeply once a week.
  • After the first two years, water the plants deeply every two weeks or so.
  • If you live in an area with hot, dry summers, you may need to water the asparagus plants more often.

How Much Water to Give Asparagus

  • The asparagus plants need 1-2 inches of water per week.
  • You can check the moisture level of the soil by sticking your finger into the ground. If the soil is dry to the touch, it is time to water.
  • Do not overwater the asparagus plants. Too much water can cause root rot.

How to Water Asparagus

  • The best way to water asparagus is with a soaker hose or drip irrigation system.
  • This will help to ensure that the water is evenly distributed and that the roots of the plants are not disturbed.
  • If you do not have a soaker hose or drip irrigation system, you can water the asparagus plants by hand.
  • Use a watering can or hose to water the plants deeply at the base.

Tips for Watering Asparagus

  • Water the asparagus plants in the morning or evening. This will help to prevent the water from evaporating too quickly.
  • Water the asparagus plants during the cooler months of the year. This will help to prevent the roots from getting too hot.
  • Mulch around the asparagus plants to help retain moisture and suppress weeds.

By following these tips, you can ensure that your asparagus plants are getting the water they need to thrive.

Mulch Around the Asparagus

Mulching is a valuable technique that can greatly benefit asparagus plants. By applying an appropriate layer of mulch around your asparagus patch, you can help conserve soil moisture, suppress weed growth, regulate soil temperature, and promote overall plant health. In this article, we will explore the step-by-step process of mulching around asparagus, ensuring that you provide optimal growing conditions for this flavorful and nutritious vegetable.

Mulching around asparagus should be done in the spring, after the soil has warmed up and the asparagus spears have emerged. Choose organic mulch materials such as straw, shredded leaves, grass clippings, or compost. These materials break down over time, adding organic matter to the soil and enhancing its fertility.

Once the area is weed-free, spread a layer of mulch around the asparagus plants. Apply a 2 to 3-inch layer of mulch, taking care to keep it a few inches away from the base of the plants to prevent moisture-related issues. Ensure that the mulch extends at least 12 inches beyond the asparagus rows to provide a wider weed-free zone.

Throughout the growing season, regularly inspect the mulch layer and make adjustments as needed. If the mulch layer becomes thin or decomposes, replenish it with fresh mulch to maintain its benefits. Ensure that the mulch layer remains consistently thick to suppress weed growth, conserve moisture, and regulate soil temperature.

How To Harvest Asparagus

Asparagus is a delightful spring vegetable that rewards gardeners with its tender and flavorful spears. Knowing the proper techniques for harvesting asparagus is essential to ensure a bountiful harvest and encourage the continued production of this delectable vegetable. In this article, we will delve into the step-by-step process of harvesting asparagus, from identifying the right time to picking the spears, allowing you to enjoy the fruits of your labor in the garden.

Patience is key when it comes to harvesting asparagus. It is important to resist the temptation to harvest the spears too early in the plant’s life. Asparagus plants need time to establish and develop strong root systems. Generally, it is recommended to wait until the third year after planting before beginning the harvest. This patience allows the plants to grow and accumulate energy for future growth and production.

To harvest asparagus, grasp the spear near the base and gently snap or cut it just above the soil level. If the spear is snapped, it will naturally break at the point where the tender portion meets the tougher, fibrous portion. This method ensures that you harvest only the edible portion, leaving the rest of the plant to continue growing and storing energy for future production.

Asparagus has a relatively short harvest window, typically lasting around 6 to 8 weeks in the spring. During this time, check your asparagus patch every 1 to 2 days for new spears that have emerged. Harvest the spears promptly while they are still tender and before they become woody or start to open up into fern-like fronds. Regular harvesting also encourages the plant to produce more spears, extending the overall harvest period.

How To Care For Asparagus

To ensure a bountiful harvest next spring, be sure to fertilize the asparagus plants in the fall with a balanced fertilizer. For the same fertilizer used in Ace’s Garden, go with FOOP Organic 10-10-10 liquid fertilizer. Simply water the liquid fertilizer into a few fall feedings.

With proper care, asparagus can be a productive crop for many years.
