Cultivation
The Ocimum iringense Ayob., commonly known as Kenya Basil, is an annual herb that grows in warm and humid climates. It thrives in well-draining soil with a pH range of 6.0-7.0. The plant requires a lot of sunlight, at least 5-6 hours of direct sunlight per day, and it's best to grow it in open fields or gardens.
You can start the seeds indoors a few weeks before the last frost date or sow them directly in the garden bed, especially in warm climates. Plant the seeds ¼ inch deep and 8-12 inches apart. Cover the seeds with soil, water them lightly and keep the soil moist until they germinate, which should take 5-10 days.
Watering
Kenya Basil requires regular watering, especially during dry and hot seasons. The soil should be allowed to dry out partially between watering to avoid waterlogging. Young seedlings and plants need more water to help them establish their roots. Mulching around the plant can help retain moisture and prevent weed growth.
Fertilization
The plant needs balanced fertilization throughout its growing phase to produce a bountiful harvest. Apply a slow-release granular fertilizer to the soil before transplanting or sowing the seeds and repeat after three to four weeks. You can also apply liquid fertilizer every one or two weeks during the growing season to encourage healthy growth and plentiful bloom.
Pruning
Pruning Ocimum iringense Ayob. is not necessary, but it can help promote bushier growth and increase the yield. Once the plant grows to a few inches tall, pinch off the tip of the stem to encourage more branching. Continuously pinch off the tips of the new branches to create more lateral shoots. Regular pruning can prevent the plant from blooming prematurely and prolong its growth phase.
Propagation of Ocimum iringense Ayob.
Ocimum iringense Ayob. or the Kenyan basil belongs to the Lamiaceae family and is a perennial herb that is commonly grown for its aromatic leaves. Propagation of this plant can be done through various methods such as seeds, cuttings, and division.
Propagation through Seeds
The easiest and most common method of propagating Ocimum iringense Ayob. is through seeds. The seeds should be sown in well-drained soil in a warm area. The seeds usually germinate within 1-2 weeks and require regular watering. Once the seedlings have grown to a reasonable size, they can be transplanted to their final location with a minimum spacing of about 30 cm apart.
Propagation through Cuttings
Propagation through cuttings is another suitable method for Ocimum iringense Ayob. Cuttings should be taken from the top part of the plant, which are usually softwood or semi-hardwood. The cuttings should be about 10-15 cm long and should be stripped off their lower leaves. They should be then planted in well-drained soil in a warm area, preferably in a greenhouse. Regular watering and misting of the cuttings will aid in the rooting process. The cuttings will usually root in 2-3 weeks and can be transplanted to their final location.
Propagation through Division
Propagation through division is another method that can be used for Ocimum iringense Ayob. This method is best suited for mature plants that need to be divided to make the most out of them. The plant should be carefully removed from the soil, and the roots should be gently subdivided. Each subdivided part should have a good amount of roots to promote survival. The divided plants should be planted in well-drained soil in a warm area with regular watering.
Overall, Ocimum iringense Ayob. is an easy plant to propagate. Propagation of the plant can be done through seeds, cuttings, and division. With the right conditions, new plants can be established from these methods and produce aromatic leaves suitable for culinary and medicinal purposes.
