Cultivation methods
Ocimum hians Benth. var. macrocaulon Briq. is a perennial plant that thrives in warm and humid climates. It can be grown in a variety of soils, including clay, loam, and sandy soils. The plant should be grown in a location that receives full sun exposure. In areas where temperatures drop below freezing, it is best to grow the plant in a greenhouse or as an indoor plant. To propagate the plant, take stem cuttings during the growing season and root them in sandy soil or water. They should be transplanted after roots develop in 2-3 weeks.
Watering needs
Consistent soil moisture is essential for the growth and development of the Ocimum hians Benth. var. macrocaulon Briq. plant. Water the plant once or twice a week, depending on the soil's moisture content. The soil should be kept moist but not waterlogged. In hot and dry weather, it may be necessary to water the plant more often. However, it is important to avoid overwatering, which can lead to root rot and other fungal diseases.
Fertilization
The Ocimum hians Benth. var. macrocaulon Briq. plant should be fertilized regularly to promote healthy growth. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Fertilize the plant every 2-3 weeks during the growing season. However, avoid fertilizing the plant during the dormant season. Over-fertilization can cause leaf burn and other problems, so be sure to follow the recommended dosage on the fertilizer package.
Pruning
Pruning is essential to maintain the shape and size of the Ocimum hians Benth. var. macrocaulon Briq. plant. Pinch off the tips of the stems regularly to encourage lateral growth and bushiness. You can also remove the flowers as they appear to promote more vegetative growth. Pruning the plant regularly also helps to prevent pests and diseases and ensures that the plant stays healthy and vigorous over time.
Propagation of Ocimum hians Benth. var. macrocaulon Briq.
Ocimum hians Benth. var. macrocaulon Briq. is commonly known as the Giant African Basil. It is an aromatic herb with multiple medicinal properties and is propagated vegetatively.
Propagation Methods
The most common propagation method for Ocimum hians Benth. var. macrocaulon Briq. is through stem cuttings. The stem cuttings are taken from the mother plant during its active growth phase. The cuttings should be 5-6 inches long and must have at least two to three nodes on them.
The next step is to prepare the stem cuttings for propagation. The lower leaves from the stem need to be stripped, and the remaining leaves must be trimmed by half to reduce transpiration. The cuttings must then be dipped in rooting hormones and planted in a well-drained potting mixture.
The planted cuttings should be placed in a warm area with bright indirect light and kept moist by watering them regularly. Within 2-3 weeks, roots will begin to emerge from the cuttings. The new plants must be kept in the same container with regular application of a water-soluble fertilizer until they have developed a strong root system.
The propagated plants can be transplanted into larger containers or directly into the ground after they reach a height of 4 to 6 inches and have developed a good root system. The planting site must receive bright indirect light and should have fertile, well-drained soil with a pH range of 6.0 to 7.5.
Propagation of Ocimum hians Benth. var. macrocaulon Briq. is an easy process, and you can propagate the plant multiple times to ensure a constant supply of fresh basil.
