Key Soil Tips

  • Use fresh, high-quality seed-starting mix

  • Avoid mixes with large bark chunks

  • Keep soil moist but not saturated

  • Ensure good air circulation to avoid damping off


🌱 How to Start Herb Seeds Indoors

1. Fill Trays with Seed-Starting Mix

Pre-moisten the soil before planting.

2. Sow Seeds Correctly

Some herb seeds require light; others need covering:

  • Basil, oregano, thyme → surface sow, lightly press in

  • Parsley, dill, cilantro → cover lightly with fine soil

3. Keep Warm and Evenly Moist

Ideal germination temperature: 65–75°F.

4. Provide Strong Light

Herbs need 12–14 hours of light daily.
Grow lights help seedlings stay compact and strong.

5. Transplant After Frost

Harden off slowly over 3–5 days before planting outdoors.


🌿 Growing Herbs Outdoors

Sun Requirements

Most herbs thrive with full sun (6–8 hours daily).
Shade-tolerant herbs: mint, parsley, cilantro.

Spacing

  • Basil: 10–12"

  • Dill: 10–16"

  • Parsley: 8–10"

  • Thyme & oregano: 12–18"

Watering

Water deeply and allow the soil to dry slightly between waterings.

Fertilizing

Use a light, balanced fertilizer every few weeks.
Avoid overfeeding — strong fertilizer can weaken flavor.


🌱 Harvesting Herbs for the Best Flavor

  • Pick basil tips to promote branching

  • Harvest dill before flowering if you prefer tender leaves

  • Cut thyme, sage, and oregano just as buds form

  • Always harvest in the morning for the most aroma

  • Regular cutting encourages more growth
