Gilbertiodendron ivorense prefers warm and humid conditions for optimal growth. The plant's natural habitat temperature ranges from 20 to 28o C, with a relative humidity of 80% and above. The plant can withstand occasional temperature fluctuations, but extreme heat or cold temperatures will damage its growth and development, leading to reduced leaf size, leaf loss, and stunted growth.
Cultivation methods:
The Gilbertiodendron ivorense plant, commonly known as Wama, is native to tropical West Africa. It can grow up to 50 meters (160 feet) in height and thrives well in regions that experience high rainfall throughout the year. To cultivate this plant, you need to ensure that it is grown in an area with well-draining soil that is rich in organic matter. The plant can grow in both shaded or open areas, but you need to ensure that it receives enough sunlight to thrive.
Watering needs:
The Wama plant requires consistent watering to grow and thrive. During the dry season, you need to water the plant at least twice a week to ensure that the soil remains moist. During the rainy season, you need to ensure that the soil does not get waterlogged, which may cause the roots to rot. It is recommended that you water the plant in the evening or early in the morning to reduce water loss due to evaporation.
Fertilization:
To encourage healthy growth of the Wama plant, you need to fertilize it regularly. It is recommended that you use a slow-release fertilizer that is rich in nitrogen, phosphorus, and potassium. You can apply the fertilizer twice a year, during the rainy season when the plant is actively growing. You may also add organic matter, such as compost, to the soil, which helps improve the soil's quality and fertility.
Pruning:
Pruning is an essential part of cultivating the Wama plant. You need to prune the plant regularly to remove dead or diseased branches and promote healthy growth. You may also prune the plant to maintain a desired shape or size. Pruning should be done during the dry season to avoid causing shock to the plant during the rainy season. It is recommended that you use sharp pruning shears to avoid damaging the branches when pruning.
Propagation of Gilbertiodendron ivorense
Gilbertiodendron ivorense, commonly known as Wengé, is a tropical rainforest tree species found mainly in West Africa. The plant is highly valued for its durable wood and is widely used in making furniture, flooring, and paneling. The tree can grow up to 50 meters tall with a diameter of about 1 meter, and its seeds are dispersed through both wind and water.
Seed Propagation
Seeds can be collected from mature trees during the fruiting season. The seeds are then dried and stored until they are ready to germinate. To improve germination rates, the seeds should be scarified either mechanically or chemically using a concentrated sulfuric acid solution. The seeds are then sown in a well-draining, moist, and fertile medium containing sand, peat moss, or vermiculite.
After sowing, the seeds should be covered with a thin layer of the growing medium and kept under high humidity and moderate light conditions. The germination process usually takes between 1 to 3 months, and the young seedlings can be transplanted to individual pots or directly into the field when they are about six months old.
Cuttings Propagation
Gilbertiodendron ivorense can be propagated through cuttings. The cuttings can either be taken from mature trees or young seedlings. A stem cutting of about 10-15cm long should be taken, and the leaves on the lower part of the stem should be removed. The cutting should be treated with a rooting hormone and planted in a well-draining soil medium, covered with a transparent polythene bag to maintain high humidity and kept under moderate light conditions.
The rooting process usually takes between 4 to 6 weeks, and the cuttings can be transplanted to individual pots or directly into the field when they have developed roots and new leaves.
Air Layering Propagation
Gilbertiodendron ivorense can also be propagated through air layering. This involves taking a branch from a mature tree and wounding the bark where roots will develop. The wounded area is then wrapped with a moistened sphagnum moss and covered with plastic to maintain high humidity. The roots will develop within a few months, and the new plant can be cut and transplanted into a new pot or directly into the field.
