Light Requirements
Ocimum tereticaule Poir. prefers bright sunlight and requires at least 6 hours of direct sunlight each day. It can grow in partial shade as well, but the plant produces less foliage under low light conditions and may flower less frequently. Therefore, it is recommended to grow this plant in an area with bright and direct sunlight for optimal growth.
Temperature Requirements
The plant Ocimum tereticaule Poir. grows well in a warm and humid environment. It thrives in temperatures ranging from 20°C to 30°C and requires a minimum temperature of about 10°C for survival. Temperatures below 10°C can damage the plant and cause it to die. Therefore, it is recommended to grow this plant in a warm and protected environment.
Soil Requirements
Ocimum tereticaule Poir. prefers well-drained and fertile soil that is rich in organic matter. The soil pH should be between 6.0 and 7.5 for optimal growth. The plant requires regular watering to keep the soil moist, but over-watering should be avoided as it can lead to root rot and other fungal diseases.

Cultivation Methods for Ocimum tereticaule Poir.
Ocimum tereticaule Poir., commonly known as spineless basil or Greek basil, is an easy-to-cultivate herb with Mediterranean origins. It can be grown both indoors and outdoors and requires minimal care.
To grow Ocimum tereticaule Poir., plant the seeds in well-draining soil with a pH range between 6.0 to 7.5. The seeds require warmth to germinate. So, it is recommended to sow them indoors in early spring, three to four weeks before the last frost. Once the seedlings develop their first set of true leaves, transplant them to larger containers or outside in a sunny location. The plant grows well in full sun or partially shaded conditions.
Watering Needs for Ocimum tereticaule Poir.
Ocimum tereticaule Poir. requires regular watering to thrive. The soil should be kept moist but not waterlogged. It is recommended to water the plant in the early morning, so the foliage dries before the onset of the evening's cooler temperatures. The frequency of watering depends on the plant's location and weather. In hot, dry weather, the plant may need watering twice a day. In contrast, in cooler weather, the plant may require watering once every three to four days.
Fertilization of Ocimum tereticaule Poir.
Ocimum tereticaule Poir. requires regular fertilization to ensure healthy growth. Fertilize the plant with a balanced water-soluble fertilizer every two weeks, following the manufacturer's instructions. Do not over-fertilize the plant as it can lead to a decrease in essential oil production and plant growth.
Pruning Ocimum tereticaule Poir.
Pruning Ocimum tereticaule Poir. is an essential task to promote bushier plants and increase yields. Pinch off the plant's growing tips regularly to encourage lateral shoots. Prune any dead or yellowing leaves or stems as soon as possible. Remove the flower buds as they appear to prevent the plant from bolting and ensure that the plant focuses on foliage growth.
Propagation of Ocimum tereticaule Poir.
Ocimum tereticaule Poir., commonly known as 'winter tulsi,' is an evergreen shrub native to the Indian subcontinent. The plant is widely grown for its medicinal and culinary uses. To propagate Ocimum tereticaule Poir., there are different methods available. Some of them are:
Seed propagation:
Seed propagation is the most common method used for Ocimum tereticaule Poir. Seeds are readily available in local nurseries or online retailers. The seeds should be sown during the warmer months of the year when the temperature is around 25-30 °C. The seeds should be sown in a well-draining potting mix, kept moist, and placed in a warm, bright spot. Germination can take up to 2-3 weeks, depending upon the conditions provided. Once the seedlings are 4-6 weeks old, they can be transplanted into larger pots or directly into the ground.
Cutting propagation:
Cutting propagation is another method used for Ocimum tereticaule Poir. Cuttings are typically taken during the summer months when the plant is actively growing. Select a healthy, mature plant, and take a 6-inch long cutting from one of its branches. Remove the leaves from the bottom half of the cutting and dip the cut end in a rooting hormone. Pot the cutting in a well-draining potting mix, keep it moist, and place it in a warm, bright spot. The cutting should root within 4-6 weeks, after which it can be transplanted into a larger pot or directly into the ground.
Division propagation:
Division propagation is a method used for mature plants that have grown large enough to divide into smaller sections. Dig up the plant carefully, and separate the roots into smaller sections using a sharp, clean knife. Each section should have a few stems and a healthy amount of roots. Pot each section in a well-draining potting mix, keep it moist, and place it in a warm, bright spot. The new plants should begin to grow within a few weeks, after which they can be transplanted into larger pots or directly into the ground.
Disease and Pest Management for Ocimum tereticaule Poir.
Ocimum tereticaule Poir., commonly known as African basil, is a popular culinary herb that is highly susceptible to a range of diseases and pests. Effective disease and pest management strategies are essential to ensure that the plant grows vigorously and produces a good yield. In this article, we will discuss some of the common diseases and pests that affect African basil and suggest ways to manage them.
Common Diseases
1. Fusarium wilt: This fungal disease is a major problem for African basil, causing wilting and yellowing of the leaves. To manage this disease, it is important to practice good sanitation by removing and destroying infected plants. Crop rotation and the use of fungicides can also help prevent the spread of the disease.
2. White mold: Another common fungal disease, white mold causes a fluffy white growth on the leaves and stem of the plant. Removing infected plant material and good air circulation can help manage this disease.
3. Bacterial leaf spot: This disease causes small, water-soaked spots on the leaves that eventually turn brown. Copper-based fungicides can help manage this disease.
Common Pests
1. Aphids: These small insects feed on the sap of the plant, causing stunted growth and yellowing of the leaves. Wash the plant with a strong stream of water or use insecticidal soap to manage this pest.
2. Spider mites: Spider mites are tiny pests that usually feed on the underside of leaves, causing yellowing and stippling of the foliage. Regularly spraying the plant with water or using insecticidal soap can help manage spider mites.
3. Whiteflies: These small, winged insects feed on the sap of the plant and can cause yellowing of the leaves and a decrease in plant vigor. Insecticidal soap and sticky traps can help manage this pest.
Good cultural practices, such as maintaining proper spacing and promoting good air circulation, and the use of resistant varieties can also help manage diseases and pests in Ocimum tereticaule Poir. To ensure the success of your African basil crop, it is important to regularly monitor your plants for signs of disease and pest infestation and take appropriate action in a timely manner.
