📅 Planting Calendar (WV Zone 6b/7a)

Method Timing Notes
Direct sow seeds May 15 - June 1 After all frost danger, soil warm (60°F+)
Start seeds indoors March 15 - April 1 Transplant after frost, 6-8 weeks before
Transplant seedlings May 15 - May 30 After last frost (typically May 10-15)
First harvest 60-70 days from seed Pinch flowers, harvest leaves
Self-seeding Allow to flower late summer Seeds may germinate next spring

🌱 Expected Yield

  • Per plant: ¼-½ lb leaves per season (with regular harvesting)
  • Per patch (10'x10'): 4-6 lbs leaves (20-25 plants)
  • Lifespan: Annual in WV—killed by first frost (October). Self-seeds moderately.

🌿 Growing Conditions

  • Soil: Rich, moist, well-drained loam with high organic matter. Does NOT tolerate poor, dry soil.
  • Fertilizer: Moderate to heavy feeder. Rich soil = lush growth. Apply compost, side-dress with balanced organic fertilizer monthly.
  • Mulching: 2-3" straw or leaves. Critical for moisture retention. Basil wilts quickly in drought.
  • Companions: Tomatoes (mutually beneficial, repels flies/mosquitoes), peppers, oregano
  • Avoid: Rue, sage (allelopathic)
  • Pests: Japanese beetles, slugs, aphids. Hand-pick beetles. Generally fast-growing enough to tolerate some damage.
  • Diseases: Fusarium wilt (emerging problem—use resistant varieties), downy mildew, bacterial leaf spot. Good air circulation essential.
  • Containment: Self-seeds moderately. Not invasive. Deadhead to prolong leaf production.

CRITICAL NOTES: - Frost kills basil instantly—protect or harvest before first fall frost - Pinch flowers to prolong leaf production (bolting changes flavor) - Never refrigerate fresh basil—turns black. Store at room temp or preserve. - Fusarium wilt is widespread—choose resistant varieties when possible

🌾 Seed Saving / Propagation

  • Seed method: Plants send up flower spikes (white, pink, or purple). Each flower produces 4 small black seeds. Harvest when flower heads brown and dry.
  • Isolation: 2+ miles (insect-pollinated, crosses easily between basil varieties)
  • Viability: 5-7 years
  • Special notes: Easy to save seed. Cut flower heads, place in paper bag, shake to release seeds. Seeds tiny (1/16"). Self-seeds readily but not aggressively. In Zone 6, self-sown seeds may not survive winter unless well-mulched.
