Basil comes in many varieties and can add flavour to your cooking at every meal. Thai basil, also known as Oriental basil or Asian basil, provides more of a kick for cuisines that call for heavy spices, such as Indian or Thai foods. As with the other basil varieties, Thai basil is easy to care for and needs two key elements -- plenty of sunlight and well drained soil -- to grow.
Plant Thai basil seeds in a shallow container indoors, outside after the danger of frost has passed, or when the day and night temperatures are above 10 degrees C (50F).
Spread seed thinly and cover with 3 mm (1/8 inch) of rich soil. Space rows of plants about 30 to 45 cm (12 to 18 inches) apart.
Keep your Thai basil plant exposed to heavy sunlight all the time, if possible, or at least four to six hours per day. Moisten soil often. Expect germination to occur one to two weeks after planting seeds.
Move indoor plants outside when they reach 5 cm (2 inches) tall. Spread seedlings 20 to 25 cm (8 to 10 inches) apart, as basil's route system is very vigorous. Continue to feed the Thai basil plant with compost and fertiliser to keep the soil rich.
Remove leaves at the top section of a stem instead of one-by-one. Pinch off leaves at the intersection of the leaves to encourage new growth. Prevent flowering of the Thai basil plant by removing shoots often.
Rinse newly cut leaves under cool water and pat dry before using. Add Thai basil to Thai, Indian and Italian recipes for salads, soups, stir fry and other meals. Include Thai basil in tea or oil and vinegar dressing.
Don't waterlog the plant. Allow the soil to dry out between waterings.
Don't allow exposure to frost. Keep the basil plant inside during autumn, winter and spring.
