It belongs to the family Malvaceae which includes cotton, hibiscus, and okra. It is commonly known as "Attieke Cola" in Ivory Coast and "Gbanja Kola" in Sierra Leone.
General Appearance
Cola attiensis is a tree that can grow up to 15-20 meters tall. It has a straight trunk with a diameter of 30 cm. The bark is grayish-brown, and the branches are long and slender. The leaves are glossy green and oblong-shaped, measuring up to 20 cm long and 8 cm wide. The tree produces flowers that are yellow or greenish-white and have a sweet fragrance. The fruit is a capsule that measures up to 10 cm long and contains up to six seeds.
Uses
The seeds of Cola attiensis are commonly used in traditional medicine for their stimulant and aphrodisiac properties. They contain caffeine, theobromine, and other alkaloids that help improve cognitive function, increase energy levels, and enhance mood. In West Africa, the seeds are chewed or brewed into tea and used to treat fatigue, asthma, and mental illnesses. The tree's timber is used for furniture-making, and the leaves are used for animal fodder. In addition, the plant plays an important cultural role in West African societies and is used in various social and religious ceremonies.
Light Requirements
Cola attiensis Aubrév. & Pellegr. var. attiensis requires moderate to high light intensity to grow and develop properly. It thrives well under full sun exposure or partial shade. However, it is essential to avoid exposing the plant to direct sunlight for too long, as this can cause leaf scorching.
Temperature Requirements
Cola attiensis Aubrév. & Pellegr. var. attiensis prefers a warm and humid environment with a temperature range of 20-30°C. It cannot tolerate temperatures below 15°C, which can lead to stunted growth and leaf drop. Extreme heat above 35°C can also cause wilting and drying of leaves.
Soil Requirements
This plant thrives in well-draining, moderately fertile soil with a pH range of 5.5-7.5. It requires regular watering to keep the soil moist but not waterlogged, as waterlogging can cause root rot. Organic matter like compost or rotted manure added to the soil can improve its water retention and nutrient content.
Cultivation Methods:
The Cola attiensis Aubrév. & Pellegr. var. attiensis plant thrives in a tropical rainforest climate, so it is necessary to recreate these conditions in cultivation. The plant requires temperatures above 60°F and high humidity, preferably above 70 percent. You can grow it in a pot or in the ground, but ensure that you plant it in well-draining soil with plenty of organic matter.
Watering Needs:
Cola attiensis Aubrév. & Pellegr. var. attiensis requires consistent watering to maintain the appropriate moisture. Depending on the temperature and relative humidity, water every 2-3 days to keep the soil beyond moist but not too soggy. Ensure the pot or soil has drainage to allow water to flow through to avoid root rot.
Fertilization:
Cola attiensis Aubrév. & Pellegr. var. attiensis requires regular fertilization to optimize plant growth. Use a complete fertilizer with equal amounts of nitrogen, phosphorus, and potassium, and apply every four weeks during the growing season. A balanced fertilizer will help keep the foliage greener and enhance the quality of flowers.
Pruning:
Cola attiensis Aubrév. & Pellegr. var. attiensis requires minimal pruning. However, you may remove dead or damaged leaves to keep the plant looking healthy. Additionally, it would help if you trimmed the tips of the branches to encourage branching and a bushier appearance.
Propagation of Cola attiensis Aubrév. & Pellegr. var. attiensis
Cola attiensis Aubrév. & Pellegr. var. attiensis can be propagated through several methods, including seed propagation, cutting propagation, and grafting propagation.
Seed Propagation
The easiest way to propagate Cola attiensis Aubrév. & Pellegr. var. attiensis is through seeds, which can be collected from mature fruit capsules in the wild or purchased from seed suppliers. The seeds must be planted in well-drained soil and kept moist until they germinate. The germination process can take up to several months, as the plant has a deep dormancy that must be broken first.
Cutting Propagation
Another way to propagate Cola attiensis Aubrév. & Pellegr. var. attiensis is through cutting propagation. To do this, cut a 10 to 15 cm stem from a mature plant in early spring. Strip the leaves from the bottom half of the stem and plant it in a mix of sand and perlite. Keep the soil moist and maintain high humidity around the cutting until it develops roots, which can take up to several weeks.
Grafting Propagation
Grafting can also be used to propagate Cola attiensis Aubrév. & Pellegr. var. attiensis, especially for commercial production. The plant is typically grafted onto a rootstock of a closely related species that provides better disease resistance, vigor, and cold-hardiness. The grafting process must be done by a skilled worker, as it involves joining the scion and rootstock, aligning the vascular tissues, and protecting the graft until it heals.
Disease and Pest Management for Cola attiensis Aubrév. & Pellegr. var. attiensis
Cola attiensis is a species of tree native to Africa, with medicinal and economic value. Like any other plant, it can suffer from various diseases and pests that can impact its growth, yield, and quality.
Common Diseases
The most common diseases affecting Cola attiensis include:
- Anthracnose: a fungal disease that causes small lesions on leaves and fruits and can lead to defoliation and yield loss. To manage, remove infected plant parts and apply fungicides.
- Leaf spot: a bacterial or fungal disease that causes yellow to brown spots on leaves. To manage, remove infected leaves and apply fungicides or bactericides.
- Root rot: a fungal disease that affects the roots, causing stunted growth and wilting. To manage, improve soil drainage, avoid overwatering, and apply fungicides.
Common Pests
The most common pests affecting Cola attiensis include:
- Mites: tiny arachnids that feed on sap, causing yellowing and curling of leaves. To manage, use predatory mites, insecticidal soap, neem oil, or other insecticides.
- Caterpillars: larvae of moths or butterflies that feed on leaves and fruits, causing defoliation and yield loss. To manage, handpick caterpillars, use Bacillus thuringiensis (Bt), or apply insecticides.
- Mealybugs: small, soft-bodied insects that feed on sap and produce a white, waxy substance that covers their bodies. To manage, use predatory insects, insecticidal soap, neem oil, or other insecticides.
It is important to regularly monitor Cola attiensis for any signs of disease or pest infestation to promptly apply necessary controls. Prevention, such as maintaining good soil health, proper irrigation, and using disease-free planting materials, is also crucial in disease and pest management.
