HOW TO CARE RED THAI BASIL:
Although regular watering is essential, once established, Thai basil is easy to grow. Harvest regularly and remove flower spikes to delay your basil running to seed. Thai basil prefers a moist soil, so enrich with compost and manure, water regularly, and mulch to reduce water loss through evaporation.
Thai basil prefers soil that is lightly moist, slightly acidic, well-drained and rich in organic matter, such as compost. It thrives in full sun but will tolerate part shade.
