When to Plant Asparagus in Colorado

Asparagus is a delicious and nutritious vegetable that can be enjoyed fresh from the garden or used in a variety of recipes. But if you’re a Colorado gardener, you know that our unique climate presents some challenges when it comes to growing this perennial favorite. So, when is the best time to plant asparagus in Colorado to ensure a bountiful harvest for years to come?

Let’s delve into the specifics of planting asparagus in the Centennial State and equip you with the knowledge to cultivate this rewarding crop successfully.

Understanding Colorado’s Climate and Asparagus Planting

Colorado’s climate, characterized by dry air, abundant sunshine, and unpredictable temperature swings, demands a strategic approach to asparagus planting. Unlike warmer regions where asparagus can be planted in spring, fall planting reigns supreme in Colorado.

Planting asparagus crowns in the fall, ideally between late September and early October, allows them to establish strong root systems before the ground freezes. This head start ensures that your asparagus plants are ready to emerge vigorously come springtime.

Step-by-Step Guide to Planting Asparagus in Colorado

1. Selecting the Right Asparagus Variety

Choose asparagus varieties that are well-suited to Colorado’s climate. Some recommended options include:

  • ‘Jersey Giant’: This popular variety is known for its large, tender spears and good disease resistance.
  • ‘Purple Passion’: Offering a unique color and sweet flavor, ‘Purple Passion’ adds visual interest to the garden.
  • ‘Mary Washington’: An heirloom variety, ‘Mary Washington’ is prized for its reliable yields and classic asparagus flavor.

2. Choosing the Perfect Planting Location

  • Sunlight: Select a location that receives at least 6-8 hours of direct sunlight per day. Asparagus thrives in sunny spots.
  • Soil: Ensure well-drained soil with a pH between 6.0 and 7.0. Amend heavy clay or sandy soils with organic matter to improve drainage and fertility.

3. Preparing the Asparagus Bed

  • Remove Existing Vegetation: Clear the planting area of any weeds, grass, or existing plants.
  • Improve Drainage: Dig a trench approximately 12-18 inches deep and 18-24 inches wide.
  • Amend the Soil: Mix the excavated soil with compost, aged manure, or other organic matter to improve drainage and fertility.

4. Planting Asparagus Crowns

  • Spacing: Space asparagus crowns 12-18 inches apart within the trench.
  • Planting Depth: Position the crowns so that the buds are 6-8 inches below the soil surface.
  • Backfilling: Gently backfill the trench with the amended soil, ensuring that the crowns are completely covered.

5. Watering and Mulching

  • Watering: Water the newly planted asparagus crowns thoroughly to settle the soil.
  • Mulching: Apply a 2-3 inch layer of organic mulch, such as straw or wood chips, around the plants to conserve moisture and suppress weeds.

Caring for Your Asparagus Plants

  • Watering: Water deeply and consistently, especially during dry periods.
  • Fertilizing: Fertilize annually in early spring with a balanced fertilizer.
  • Weed Control: Keep the asparagus bed weed-free to minimize competition for nutrients and water.

Harvesting Your Asparagus Bounty

Patience is key when it comes to harvesting asparagus. Allow the plants to grow for two full years after planting before harvesting any spears. In the third year, you can enjoy a limited harvest for a few weeks. From the fourth year onward, harvest asparagus spears for 6-8 weeks.
