What You’ll Need

  • Mulch

Choosing the Right Variety

Asparagus comes in several varieties. Some popular types include:

  • Mary Washington: Traditional green spears.
  • Jersey Knight: High yield and disease-resistant.
  • Purple Passion: Sweet, purple spears.

Preparing the Soil

Asparagus prefers well-drained, fertile soil with a pH of 6.5-7.5. Here�s how to prepare your soil:

  1. Loosen the Soil: Till the soil to a depth of 12 inches (30 cm). Remove any stones or debris that could impede root growth.
  2. Add Compost: Mix in 2-3 inches (5-7.5 cm) of compost to improve soil fertility and structure.
  3. Add Organic Matter: Incorporate well-rotted manure or homemade compost for added nutrients.

Planting Asparagus Crowns

Asparagus is typically grown from crowns. Here�s how to plant them:

  1. Dig Trenches: Dig trenches 6-8 inches (15-20 cm) deep and 12-18 inches (30-45 cm) apart.
  2. Plant Crowns: Place crowns in the trenches, spacing them 12-18 inches (30-45 cm) apart. Cover with 2 inches (5 cm) of soil.
  3. Fill Trenches: Gradually fill in the trenches with soil as the asparagus grows.

Watering and Care

Asparagus needs consistent watering and care. Follow these tips:

  • Water Regularly: Keep the soil consistently moist, but not waterlogged. Water in the morning to reduce evaporation.
  • Mulch: Apply a 2-3 inch (5-7.5 cm) layer of mulch around the plants to retain moisture and suppress weeds.
  • Weed Control: Hand weed regularly to prevent competition for nutrients.

Fertilizing

Asparagus benefits from organic fertilization. Use compost tea or fish emulsion every 3-4 weeks during the growing season.

Harvesting

Asparagus can be harvested starting in the third year after planting. Here�s how to harvest:

  • Check Regularly: Harvest spears when they are 6-8 inches (15-20 cm) tall. Cut them at ground level with a sharp knife.

Storing Asparagus

Asparagus can be stored in several ways:

  • In the Fridge: Store fresh asparagus in a plastic bag in the refrigerator crisper drawer. Use within 1-2 weeks.
  • Freezing: Blanch asparagus in boiling water for 2-4 minutes, then cool in ice water. Freeze in airtight containers for up to 6 months.

Tips and Tricks

  • Patience is Key: Allow the plants to establish for at least two years before harvesting.
  • Companion Planting: Grow asparagus with tomatoes, basil, or parsley to maximize garden space.
