Cultivation Methods
Cola bodardii Pellegr., also known as Cola by the locals, is a tropical evergreen plant that is relatively easy to cultivate. It thrives in warm, humid, and shady locations, making it suitable for growing in tropical regions.
Start by selecting a location that offers partial shade, preferably with dappled sunlight. The soil should be well-draining and rich in organic matter, with a pH range of 6 to 7.5.
To start cultivating Cola a seedbed or nursery bed should be established and transplanted to the main field after 6 months. Typically, seeds from the matured fruits of Cola are selected for planting. The seeds should be sown at a depth of about 1 cm in the prepared seedbed and watered regularly.
Once the seedlings are about 20-30cm tall, they can be transplanted into the main field at a spacing of 2-3m apart in rows. Mulching the soil around the base of each plant is advised to conserve moisture and control weed growth.
Watering Needs
Cola bodardii requires moderate watering to grow healthily. Young plants should be watered regularly to maintain the moisture content in the soil.
During dry spells and hot weather, it is advisable to increase the frequency of watering while reducing the amount of water per watering session to avoid waterlogging the soil.
For mature Cola plants, it is better to water heavily once or twice a week instead of frequent light waterings. This strategy will encourage root growth and help develop a strong root system.
Fertilization
Cola bodardii Pellegr. responds well to doses of organic fertilizers such as animal manure, compost, green manure, and poultry droppings.
Before planting, about 10-20 tonnes of matured animal manure or compost should be applied per hectare. This should be supplemented by a nitrogen-rich fertilizer such as poultry manure at a rate of 500 kg per hectare during the rainy season.
Fertilizer application should be done twice a year during the wet season, and light applications of potash-rich fertilizers such as wood ash can be applied to boost fruit production.
Pruning
Cola bodardii Pellegr. requires minimal pruning. The plant grows naturally without much intervention, and pruning should be limited to removing weak lateral branches or damaged leaves.
Pruning should preferably be done in the dry season, and pruning equipment should be disinfected to prevent the spread of diseases between plants.
Fruit thinning may also be necessary to allow the remaining fruits to mature and grow bigger.
When left to grow naturally with minimal intervention, Cola bodardii Pellegr. can produce good yields for up to 50 years, making it a low maintenance but highly productive crop.
Propagation of Cola bodardii Pellegr.
Cola bodardii Pellegr. is a tropical evergreen tree that belongs to the family Malvaceae. It is native to West and Central Africa and is widely known for its use in traditional medicine and the production of kola nuts. The plant can be propagated by various methods such as seeds, cuttings, and grafting.
Seed propagation
Cola bodardii Pellegr. can be propagated by sowing its seeds in a suitable rich and well-drained soil mix. The seeds should be soaked in water for 24 hours before planting to allow for easier germination. The ideal temperature for germination is between 25-30 °C.
The seedlings should be kept in a shaded area to protect them from direct sunlight and extreme weather conditions. After 6-8 weeks, the seedlings can be transplanted into bigger pots or in the ground when they have grown to a size of at least 10cm.
Cutting propagation
Cutting propagation is another means of propagating Cola bodardii Pellegr. for a tree that has the desired traits. It involves cutting a portion of a healthy parent tree that has desirable characteristics and planting the cutting to grow a new tree. To propagate using this method, select a healthy stem or branch that has matured and has the capacity to produce a new root system.
Carefully cut the stem or branch from the parent plant using a clean and sharp cut. Remove all the leaves except two or three from the top. Dip the end of the cutting in a rooting hormone solution and plant it in a suitable soil mix. The cutting should also be kept in a shaded area and regularly misted to keep it moist. After 4-6 weeks, the cutting should start producing new roots and can be transplanted into bigger pots or in the ground.
Grafting propagation
Grafting is a process of combining two different plants to create a new plant. In Cola bodardii Pellegr., grafting can be used to combine the rootstock of an existing tree with the scion of another tree to create a new and desirable tree.
The process involves planting the rootstock into the ground or a pot and then carefully making a cut on the rootstock. The cut should be made at an angle and the scion of the desired tree is attached to the cut. The graft area is then covered and sealed to ensure that the scion adheres to the rootstock and grows into a new plant.
Grafting should only be attempted by experienced gardeners, as the process requires a high level of skill.
