Basil 'Thai Sita' Ocimum basilicum 'Thai Sita'

Water

Thai Basil requires regular watering to keep the soil evenly moist, but not waterlogged. Water the plant when the top inch of soil feels dry to the touch—typically once every 2 to 3 days, depending on the weather and soil drainage. It is best to water the plant in the morning, using a gentle stream to soak the soil at the base without wetting the leaves. A general guideline is to provide about 16 ounces of water per plant per watering session, adjusting for size, climate, and soil conditions.

Light

Thai Basil thrives in full sun conditions, meaning it requires at least 6 to 8 hours of direct sunlight per day. It is best positioned in a south-facing window or garden spot where it can receive plenty of light. However, in extremely hot climates, some afternoon shade may be beneficial to prevent leaf scorch.

Temperature

Thai Basil prefers warm temperatures and will grow best when the ambient temperature is between 70°F and 90°F. It can tolerate a minimum temperature of 50°F, but frost will damage or kill the plant. Consistently warm conditions are ideal for thriving growth.

Pruning

Pruning Thai Basil is essential for encouraging bushier growth and preventing early flowering. Pinch off the tip of each stem every few weeks to promote branching. The best time to prune is when the plant has 6 to 8 leaves, and regular pruning can continue throughout the growing season to maintain the desired shape and size.

Cleaning

As needed

Soil

Thai Basil prefers well-draining soil with a slightly acidic to neutral pH of 6.0 to 7.5. A mix of two parts potting soil to one part coarse sand or perlite is ideal for good drainage and root aeration.

Repotting

Thai Basil should be repotted annually, or when it outgrows its current pot, to refresh the soil and provide more room for growth.

Humidity & Misting

Thai Basil thrives best at moderate humidity levels, ideally between 40% to 60%.

Suitable locations

• Indoor

  Place Thai Basil near a sunny window and water when soil is dry.

• Outdoor

  Plant in full sun with proper spacing and well-draining soil.

• Hardiness zone

Life cycle

Thai basil 'Thai Sita' begins its life cycle when the seeds are sown in warm soil in early spring or after the last frost. Germination typically takes place within a week or two, given adequate moisture and temperatures between 70-75°F (21-24°C). The seedlings develop true leaves and are transplanted once they are large enough to handle and the threat of frost has passed. As the plants grow, they enter a vegetative stage, producing lush green foliage and distinctive anise-scented leaves. Flowering occurs in late summer to early fall, producing small, purple flowers attractive to pollinators; at this stage, regular harvesting of leaves can prolong the plant's productivity. Following the flowering phase, if seeds are allowed to mature on the plant and are not harvested, they will eventually drop to the ground, completing the cycle by potentially generating new plants for the next growing season.

Propogation

• Propogation time

  Spring-Summer

• Thai Basil, a variety of Ocimum basilicum, is commonly propagated by seeds, which is the most popular method. The ideal time to sow Thai Basil seeds is after the danger of the last frost has passed in spring when soil temperatures have warmed sufficiently, typically above 70°F (21°C). To propagate Thai Basil by seeds, you should start by scattering the seeds over the surface of a light, well-drained, moist potting mix. Gently press the seeds into the soil but do not cover them too deeply; a light covering of about 1/4 inch (about 6 millimeters) is sufficient, as they require some light for germination. Keep the soil consistently moist but not waterlogged, and place the container in a warm spot with good indirect light. Germination usually takes place within 5 to 10 days. Once seedlings develop a set of true leaves and are strong enough, they can be transplanted outdoors or into individual pots.
