Cultivation Methods
Boswellia bhar-dajiana Birdw. var. serrulata Engl., commonly known as Indian frankincense, is a small tree that can grow up to 6 meters in height. It is a hardy plant that can thrive in a range of soils, from sandy loams to rocky soils, as long as they are well-drained and not waterlogged. The plant prefers full sunlight and can tolerate high temperatures. Propagation can be done via seeds or cuttings. Seeds should be sown in the early spring in a well-draining soil mix. Cuttings can be taken from healthy young stems in the summer and rooted in a moist soil mix.Watering Needs
Boswellia bhar-dajiana requires moderate watering during its growing period, which is typically from March to November. The plant is drought-tolerant and can survive on minimal watering. However, during prolonged dry spells, it is important to water it deeply to prevent the plant from drying out.Fertilization
The plant is not a heavy feeder and does not require fertilizer often. It can benefit from a slow-release, balanced fertilizer application in the spring. It is important not to over-fertilize the plant as it can lead to excessive foliage growth and a decline in resin production.Pruning
Pruning is not essential for Boswellia bhar-dajiana, but it can help to promote branching and a more compact growth habit. Pruning should be done during the dormant season when the plant is not actively growing. Any dead, diseased or damaged wood should be removed, and the tips of the healthy branches can be pruned to encourage bushier growth. It is important not to prune too much as this can reduce the plant's resin production.Propagation of Boswellia bhar-dajiana Birdw. var. serrulata Engl.
Boswellia bhar-dajiana Birdw. var. serrulata Engl. is commonly propagated by seed and cuttings, although grafting may also be done.
Propagation by Seed
Seeds should be harvested when the capsules have matured and turned yellow. The seeds should then be cleaned and dried before planting. Pre-treatment of seeds is not usually necessary, and they can be sown directly into the soil or in seed trays. Germination can take up to a month, but using a rooting hormone and keeping the seeds moist may speed up the process.
Propagation by Cuttings
Cuttings should be taken during the growing season when the plant is actively producing new growth. Semi-hardwood cuttings of around 10-15cm in length, with at least 2 nodes, should be taken from the tips of the branches and treated with rooting hormone before planting. They can be planted directly into a potting mix or into a rooting substrate, such as sand or vermiculite. Cuttings should be kept in a warm and humid environment until they have rooted, which can take up to 3 months.
Propagation by Grafting
Grafting may be used to propagate desired cultivars or to improve the plant's resistance to disease. The rootstock used for grafting should be of the same species, and the scion should be taken from the desired cultivar. T-budding or chip budding are recommended grafting techniques. However, grafting is generally not a common method for propagating Boswellia bhar-dajiana Birdw. var. serrulata Engl.
Disease and Pest Management for Boswellia bhar-dajiana Birdw. var. serrulata Engl.
Boswellia bhar-dajiana Birdw. var. serrulata Engl. is a highly valued plant that is known for producing frankincense, which is extracted from its resin.

It is, therefore, essential to have a disease and pest management plan in place to ensure that the plant remains healthy and productive.
Common Diseases
One of the most common diseases affecting Boswellia bhar-dajiana Birdw. var. serrulata Engl. is Leaf spot. It is caused by the fungus Phyllosticta spp. and is characterized by the presence of small brown or black spots on the leaves. The spots may coalesce, causing the leaves to turn yellow and fall off. To manage this disease, it is advisable to prune off and destroy the infected leaves. Additionally, applying a fungicide can reduce the severity of the disease.
Another common disease that affects the plant is Powdery Mildew. It is caused by the fungus Erysiphe cichoracearum and is characterized by the presence of white or gray powdery growth on the leaves. The disease can cause defoliation and reduced growth. To manage this disease, it is advisable to prune off and destroy the infected leaves. Additionally, applying a fungicide can reduce the severity of the disease.
Common Pests
Boswellia bhar-dajiana Birdw. var. serrulata Engl. is also susceptible to several pests. One of the most common pests is Spider mites. They are tiny pests that feed on the sap of the plant, causing it to lose vigor and eventually die. To manage this pest, it is advisable to spray the plant with a miticide or insecticide. Additionally, maintaining proper hygiene by removing debris and weeds around the plant can reduce the chances of infestation.
Another common pest that affects the plant is Mealybugs. They are small, soft-bodied insects that feed on the sap of the plant. They often appear as white cottony masses on the leaves and stem. To manage this pest, it is advisable to spray the plant with a systemic insecticide. Additionally, maintaining proper hygiene by removing debris and weeds around the plant can reduce the chances of infestation.
Conclusion
Having a disease and pest management plan for Boswellia bhar-dajiana Birdw. var. serrulata Engl. is essential in ensuring that the plant remains healthy and productive.
