Ease of Cultivation and Exotic Flavor: Thai basil is a fragrant variety known for its distinct anise-like flavor and striking purple stems. This herb is relatively easy to grow, thriving in warm, sunny conditions with regular watering. It’s a staple in many Southeast Asian dishes, including curries, stir-fries, and salads, adding a unique flavor and aroma that enhances a variety of culinary creations.

Direct Sowing: For direct sowing, plant Thai basil seeds outdoors after the last expected frost when the soil temperature is consistently above 70°F. Sow the seeds about ¼ inch deep and spaced 12 inches apart in rows that are 18–24 inches apart. Germination typically occurs within 7–14 days. Keeping the soil consistently moist is crucial during this period to promote strong growth. Once seedlings are established, thin them to provide adequate airflow and prevent overcrowding. You can begin harvesting leaves when they reach approximately 3–4 inches long, ensuring to take no more than one-third of the plant at a time.

Early Sowing for Seedlings: To get an early start, sow Thai basil seeds indoors 6–8 weeks before the last expected frost. Use seedling trays filled with quality potting mix, placing 2-3 seeds per cell. Maintain a temperature of 70–80°F to encourage germination. Once the seedlings develop their first true leaves and the danger of frost has passed, transplant them into the garden. Space the transplants about 12 inches apart in rows that are 18–24 inches apart. Water them thoroughly after planting and consider adding mulch around the base to help retain moisture and suppress weeds.

Harvesting: To determine when Thai basil is ready for harvest, look for vibrant green leaves that are aromatic and lush. You can start harvesting once the plants have sufficient foliage, typically within 70-90 days after sowing. It’s best to pick the outer leaves first to encourage bushier growth. Regular harvesting promotes continued production and helps prevent flowering, which can affect the flavor of the leaves. For the best taste and aroma, harvest in the morning when the essential oils are most concentrated.
