You’ll get the best results if you plant asparagus crowns about 12–18 inches (30–45 cm) apart in the row and leave 3–5 feet (0.9–1.5 m) between rows for airflow and access.

Quick Scoop

  • Classic home‑garden spacing:
    • 12–18 inches between plants in a row.
    • 3–5 feet between rows.
    • Good balance of yield, plant health, and easy harvesting.
  • Tighter “modern” spacing (for smaller gardens):
    • 12 inches between plants, using double or triple rows in one bed.
    • Leave about 5 feet between one double/triple-row bed and the next.
    • Research shows similar yield per plant even with closer spacing.
  • Very tight, single-row option:
    • As close as 6 inches apart in a single row along a fence or path.
    • Same yield per plant in trials, but creates a dense hedge of ferns.
  • Why the space matters:
    • Asparagus is perennial and can stay in place 15+ years, so crowding too much can shorten bed life.
    • Room between rows makes weeding, mulching, and harvesting less of a pain.

Think of each crown as a little “asparagus fountain” that will keep getting bigger every year—give it enough elbow room now so you’re not wrestling a jungle later.

Simple planting example

For a small backyard bed about 4 feet wide, you could:

  1. Run two rows down the length of the bed, each row about 18–24 inches apart.
  2. Space crowns 12–18 inches apart within each row.
  3. Plan on that bed staying asparagus-only for the long term.

TL;DR:
Plant asparagus 12–18 inches apart in rows, with 3–5 feet between rows; go closer (around 12 inches, or even 6 inches in some setups) if you’re tight on space and ready to manage a denser bed.
