Key takeaways

What to know before you act on this, from the SteadScape editors.

  • Measure your garden bed dimensions in feet; for a 4x8 bed, expect to plant approximately 32 to 64 cloves depending on spacing.
  • Choose 6-inch spacing for standard garlic varieties, but use 8-inch spacing for large bulbs or in humid climates to prevent disease.
  • Order at least 10% more garlic cloves than calculated to account for unusable ones or damage during planting.
  • Expect to pay between $10 to $30 for seed garlic, depending on the variety and quantity ordered; check for availability in late spring.
  • Plant garlic in the fall, ideally 4 to 6 weeks before the ground freezes for optimal growth before winter dormancy.
