How to grow Thai Basil

Try to plant in a location that enjoys full sun and remember to water moderately. Use Zone 4 - Zone 12 as your guideline for the appropriate climate for this plant. Ideally plant in loamy soil and try to keep the ph of your soil between the range of 6.0 and 7.5 as Thai Basil likes to be in weakly acidic soil - weakly alkaline soil. Keep in mind when planting that Thai Basil is thought of as tender, so remember to wait until your soil is warm and the night time temperature is well above freezing before moving outside.

Try to aim for a seed spacing of at least 0.5 inches (1.27 cm) and sow at a depth of around 0.12 inches (0.3 cm). Soil temperature should be kept higher than 15°C / 59°F to ensure good germination.
