Soil & Bed Preparation

Blend compost with aged bark fines to create a fluffy, well-drained bed or container mix. Basil thrives in slightly alkaline soils, so incorporate a tablespoon of dolomitic lime per square foot if pH tests below 6.0.

Watering & Feeding

Keep soil evenly moist but never soggy. In beds, water 1 inch per week; in containers, check daily during peak heat and irrigate when the top inch is dry.

Mix a slow-release organic fertilizer into the planting zone and supplement every three weeks with a diluted fish emulsion drench to keep foliage lush without turning bitter.

Training & Maintenance

Pinch the top pair of leaves as soon as plants reach 6 inches tall. Harvest by cutting stems just above a leaf node to encourage branching and prevent early flowering.

Harvest & Storage

Harvest in the cool morning for best flavor. Store stems in a glass of water on the counter and loosely cover with a bag. For longer keeping, pulse with olive oil and freeze in ice cube trays.

Planting Instructions

  • Direct sow after soil warms to 70°F
  • Or start indoors 4-6 weeks before last frost
  • Space 12-18 inches apart
  • Plant in full sun location

Care Instructions

  • Keep soil consistently moist
  • Pinch flowers to encourage bushy growth
  • Harvest frequently
  • Fertilize monthly

Seasonal Growing Calendar

Early spring

  • Start seeds indoors 4 to 6 weeks before the last frost date.
  • Provide bottom heat to speed germination and keep lights just above the seedlings.
  • Sow successive trays every two weeks for a steady supply.

Late spring

  • Transplant outdoors once night temperatures stay above 55 F.
  • Space plants 12 to 18 inches apart to allow airflow.
  • Mulch lightly with shredded leaves to moderate moisture.

Summer

  • Pinch weekly and remove flower buds immediately.
  • Rotate containers or beds if plants start to look tired; feed with compost tea.
  • Harvest heavily before storms to avoid broken stems.

Fall

  • Take cuttings of your favorite plants and root them in water indoors.
  • Dry leaves in a dehydrator set to low heat for winter spice blends.
  • Compost spent stems once nighttime temps dip into the 40s.
