Cultivation of Olia somaliensis Baker is not challenging as it can tolerate various soil types and is resistant to pests and diseases.
Watering Needs of Olea somaliensis Baker
Watering Olea somaliensis Baker is crucial during the first year after planting. During this period, ensure the plant receives adequate water to establish strong roots. Once established, the plant can tolerate harsh climatic conditions and can go for long periods without water. The tree's deep roots can extract moisture from the soil up to 20 meters deep.
Fertilization of Olea somaliensis Baker
As a hardy tree, Olea somaliensis Baker requires minimal fertilization, but applying a balanced fertilizer during the growing season will boost the tree's growth. Use a slow-release fertilizer at the start of the rainy season when the tree is actively growing. For a mature tree, apply 200g of a balanced fertilizer per year.
Pruning Olea somaliensis Baker
Pruning Olea somaliensis Baker is not necessary, but it is essential to shape the young tree to the desired shape and remove any dead or diseased branches. Prune the young trees in the early stages of growth, and avoid removing more than 30% of the foliage in any pruning session. Be cautious when pruning the mature tree, as it can expose the tree to diseases.
Propagation of Olea somaliensis Baker
Olea somaliensis Baker, commonly known as Somali olive, is a slow-growing evergreen tree native to Somalia and eastern Kenya. Propagation of this tree species can be done through various methods, including seed propagation, cuttings, and layering.
Seed Propagation
Seed propagation is the most common and easiest way to propagate Olea somaliensis Baker. The seeds are collected from mature fruits of the tree and are sown immediately after harvesting. The seeds require no pre-treatment, but soaking them in water for 24 hours can speed up germination.
The seeds are sown in a pot or container filled with well-draining soil. Cover the soil with a thin layer of sand and keep it moist. The pot should be placed in a warm and bright location, and the soil should be kept moist until the seedlings emerge. The seedlings can be transplanted into larger containers once they have grown to a suitable size.
Cuttings
Cuttings are another viable way to propagate Olea somaliensis Baker. You should collect cuttings from the mature olive tree during the dormant season, which is during late winter or early spring. The cutting should be 15-20 cm long and free of any disease or damage.
Once you have obtained the cutting, dip the cut end into rooting hormone and then plant it in a well-draining pot or container filled with moist soil. The container should be placed in a warm and bright location and the soil should be kept moist until the cuttings take root. The cutting can be transferred to a larger pot or planted in the ground once it has developed a strong root system.
Layering
Layering is also a method of propagating Olea somaliensis Baker. This method involves bending a lower branch and covering it with soil, leaving the tip of the branch exposed. The covered branch will develop roots and can be cut from the parent tree once it has developed a strong root system.
Propagation of Olea somaliensis Baker through seed propagation, cuttings, and layering can be successful if done properly. Consider the advantages and disadvantages of each propagation method before deciding which one to use.
