🌿 First, Know Your USDA Zone

The United States Department of Agriculture (USDA) has divided North America into 13 hardiness zones based on the average annual minimum winter temperature. Zones range from Zone 1 (coldest) to Zone 13 (warmest).

Not sure of your zone? You can look it up on the USDA website or by entering your zip code into any gardening app or website.


🌱 When to Plant the Most Popular Herbs by Zone

1. Basil

  • Zones 3–5: Start seeds indoors 6–8 weeks before last frost. Transplant outside in late spring (after all danger of frost).
  • Zones 6–7: Direct sow or transplant outdoors in mid to late spring.
  • Zones 8–10: Plant outdoors in early spring; basil thrives in warm temps.
  • Zone 11+: Basil can be grown year-round, but avoid hottest summer months in tropical climates.

🌞 Tip: Basil loves heat and hates cold. Even a light frost can kill it.


2. Cilantro

  • Zones 3–7: Sow seeds directly in early spring or fall. It bolts quickly in summer heat.
  • Zones 8–10: Best grown in fall, winter, or early spring.
  • Zone 11+: Cool season herb — avoid planting in peak summer.

❄️ Cilantro prefers cooler weather — plant it like a leafy green, not a summer herb.


3. Parsley

  • Zones 3–5: Start indoors 8–10 weeks before the last frost; transplant when the soil warms.
  • Zones 6–7: Direct sow or transplant in early to mid-spring.
  • Zones 8–10: Can be planted in late fall or early spring.
  • Zone 11+: Best as a winter crop or grown in partial shade year-round.

🐝 Bonus: Let parsley flower and it’ll attract pollinators!


4. Thyme

  • Zones 3–5: Start indoors and transplant after frost danger passes.
  • Zones 6–10: Direct sow or transplant in spring or early fall.
  • Zone 11+: Plant in fall or early winter, avoiding intense summer heat.

🌿 Thyme is perennial in most zones — plant once and enjoy for years!


5. Mint

  • Zones 3–10: Plant in spring after frost, or in fall in warmer zones.
  • Zone 11+: Grow in cooler seasons or as a potted plant indoors/outdoors.

⚠️ Warning: Mint is invasive — plant it in containers to keep it in check!


🛠️ Final Tips for Herb Success

  • Check frost dates: Your “last frost” and “first frost” dates are key for timing.
  • Soil matters: Most herbs need well-drained soil and at least 6 hours of sun.
  • Don’t over-fertilize: Herbs grown for flavor do best with minimal feeding.
  • Harvest often: Regular harvesting encourages more growth — and keeps herbs from flowering too soon.
