General Appearance
Commiphora pteleifolia Engl. is a small deciduous tree that grows up to 3-4 meters in height. It has a gnarled and twisted trunk that can have a diameter of up to 20 centimeters. The bark is smooth and has a grey to brown appearance. The leaves are compound, with 3 to 5 leaflets that are elliptical and pointed. The flowers are small and yellowish-green, and the fruit is a spherical drupe that is reddish-brown when ripe. When the bark is cut, it exudes a resin that is originally sticky but turns into a hard and brittle substance when dried.
Light Requirements
Commiphora pteleifolia Engl. thrives in full sun to partial shade. It is recommended to provide them with at least six hours of direct sunlight daily to support its growth and promote flowering. However, it can tolerate shade if necessary, but excessive shade may result in leggy and weak growth.
Temperature Requirements
The ideal temperature range for Commiphora pteleifolia Engl. is between 65°F to 85°F (18°C to 29°C). It grows optimally in warm climates with dry and hot summers and tolerates mild frost for a short period. Cool weather slows down its growth rate, and prolonged exposure to cold temperatures can damage the plant.
Soil Requirements
Commiphora pteleifolia Engl. prefers well-draining and nutrient-poor soils. It thrives in sandy or rocky soils with a pH range of 6.0 to 8.5. The soil should have good drainage to prevent waterlogging, which can cause root rot and other fungal diseases. Adding organic matter, such as compost or peat moss, can improve soil water-holding capacity and fertility.
Cultivation Methods
Commiphora pteleifolia Engl., also known as the Somali myrrh, is a plant that can grow up to 2 meters tall. It prefers hot and dry climates and generally thrives in well-drained soils. The plant requires plenty of sunlight to grow and should be exposed to it for at least 6 hours a day. Propagation of the plant can be through seeds, cuttings, or grafting. The plant can be grown in containers as well as in the ground.
Watering Needs
The watering needs of Commiphora pteleifolia Engl. vary depending on various factors such as the temperature, humidity, and soil type. The plant is drought tolerant, but it requires sufficient water to establish its roots and maintain its growth in the initial stages. The plant should be watered deeply, but infrequently to allow the soil to dry out slightly between waterings. During the dry season, the plants should be watered occasionally to prevent water stress and leaf drop.
Fertilization
Commiphora pteleifolia Engl. requires a small amount of fertilizer to thrive. A balanced, slow-release fertilizer such as a 10-10-10 or 20-20-20 should be applied to the plant during the growing season. The fertilizer should be applied sparingly as too much can lead to excessive growth that can weaken the plant and make it more susceptible to diseases and pests. Organic fertilizers such as compost can also be used to nourish the plant.
Pruning
The pruning of Commiphora pteleifolia Engl. should be done to promote healthy growth, remove dead or diseased branches, and shape the plant. Pruning should be done in the early spring before the onset of new growth. The plant should be pruned to remove any branches that are crossing, rubbing, or growing inwards. The plant can also be pruned to maintain its shape and size. It is advisable to use sharp and clean pruning tools to avoid injuring the plant and introducing diseases.
Propagation of Commiphora pteleifolia Engl.
Commiphora pteleifolia Engl., commonly known as “Higalo”, is a small deciduous tree that belongs to the family Burseraceae. This plant species is widely distributed across East Africa and is highly valued for its medicinal properties. Propagation of Commiphora pteleifolia Engl. is usually done through seeds and stem cuttings.
Propagation through Seeds
Propagation of Commiphora pteleifolia Engl. through seeds is a common method used by farmers and plant breeders. Seeds should be collected from mature trees during the dry season and stored in a cool and dry place. The seeds should be soaked in water for 24 hours before sowing to soften the seed coat.
The seeds can be sown in well-drained nursery beds or pots filled with a mixture of sand and soil. The seeds should be covered with a thin layer of soil and watered regularly. Germination may take several weeks, and the seedlings should be transplanted to individual pots once they have grown to a height of about 4 inches. Seedlings can be planted in the field after they have grown to a height of 6-8 inches.
Propagation through Stem Cuttings
Propagation of Commiphora pteleifolia Engl. through stem cuttings is also a viable method. Cuttings should be taken from mature trees during the dry season, and a rooting hormone can be applied to enhance root development.
The cuttings should be planted in a well-drained soil mixture. They should be placed in a shaded area and watered regularly until roots and new shoots appear. After a few months, the cuttings can be transplanted to individual pots and placed in a sunny area, and they can be planted in the field after they have grown to a height of 6-8 inches.
Overall, the propagation of Commiphora pteleifolia Engl. is relatively easy and can be done through seeds or stem cuttings. Farmers and plant breeders can use either method or a combination of the two to establish new plantations of this species.
