Plant Care & Growing Tips
To successfully cultivate your Thai Sweet Large Leaf Basil Seeds, understanding its basic care requirements is key. Basil thrives in warm conditions and requires consistent attention to light, water, and soil. Plant your seeds indoors 4-6 weeks before the last frost, or directly sow them outdoors once all danger of frost has passed and soil temperatures are consistently above 60°F (15°C). Sow seeds about ¼ inch deep and 6-12 inches apart, or closer if you plan to thin them later. Ensure the soil remains moist during germination.
This Ocimum basilicum var. thyrsiflora prefers a location with at least 6-8 hours of direct sunlight per day. In hotter climates, some afternoon shade can prevent scorching. The ideal soil for basil is well-draining, fertile, and rich in organic matter, with a pH between 6.0 and 7.0. Regular watering is crucial, especially during dry spells; aim to keep the soil consistently moist but not waterlogged. Fertilize every 2-4 weeks with a balanced liquid fertilizer, or incorporate compost into the soil prior to planting. Pinch off flower buds as they appear to encourage bushier growth and prevent the plant from going to seed, which can diminish leaf flavor. Harvesting regularly also promotes new growth. This large leaf basil is an annual plant, meaning it completes its life cycle within one growing season.
