Growing Guide

When to Grow

Begin seeds indoors 4-6 weeks before the last frost date in your region. Transplant seedlings into the garden once nighttime temperatures consistently stay above 50 F. In warmer climates, you can direct sow seeds after the last frost. Thai Sweet basil loves heat, so planting during the warmer months will result in faster growth. If you're unsure of your last frost date, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Sow seeds 1/4 inch deep in seed trays or directly in garden beds after the last frost. Maintain soil temperatures between 70 to 85°F for germination, which usually takes 6 to 10 days. Space plants 8 to 12 inches apart to ensure proper airflow and healthy growth. Harden off seedlings gradually over 7 to 10 days before transplanting to outdoor conditions to reduce transplant shock.

How to Grow

Water consistently to keep the soil moist, and fertilize every 2 to 4 weeks with compost or a balanced fertilizer to encourage healthy growth. Pinch off flower buds as soon as they appear to prolong the harvest and keep the leaves tender and flavorful. If allowed to flower, the blooms will attract pollinators like bees and butterflies. This basil can also be grown in containers if it has well-draining soil and is placed in a sunny spot. Protect it from pests like aphids and spider mites using organic methods such as neem oil or insecticidal soap.

How to Save Seeds

  • Flower heads mature progressively from the bottom of the stem to the top.
  • When the bottom seed head starts to turn brown, the stem can be cut and allowed to dry away from direct sun in a well-ventilated area.
  • Rub dried raceme over a fine wire mesh and winnow off the chaff.
  • Place chaff in a bowl and carefully swirl contents around. Seeds will gather at the bottom of the bowl.
  • Tip the bowl so that the chaff can be discarded and blow the rest out carefully.
