Appearance of Butyrospermum parkii
Butyrosperrmum parkii is a deciduous tree that sheds its leaves during the dry season. It has a deep taproot system that helps it to access water that is stored deep in the ground. The stem of Butyrospermum parkii is grayish-brown in color, and the bark is fissured with deep vertical cracks. The wood is hard, durable, and dark brown. The leaves are leathery and glossy, with a dark green color on the upper surface and a lighter green on the lower surface. The flowers of Butyrospermum parkii are small, pale yellow, and appear in clusters. The fruits are large, round, and brown, and they have a sweet pulp surrounding a hard nut that contains the Shea butter.
Light Requirements
The Butyrospermum parkii var. poissoni A.Chev. (also known as Poisson's shea butter) requires ample sunlight to grow properly. It thrives in full sun to partial shade, meaning it needs at least six hours of direct sunlight each day. The plant cannot grow well in areas with no access to sunlight, which can cause the leaves to wilt, turn yellow, and eventually die.
Temperature Requirements
This plant grows best in warm, moist environments with temperatures ranging from 25°C to 35°C. It cannot survive in areas with extreme cold or hot temperatures, making it suitable for tropical or subtropical climates. When the temperature drops below 20°C, the plant enters a dormant stage, whereby it hardly grows any new branches or leaves.
Soil Requirements
Butyrospermum parkii var. poissoni A.Chev. requires well-draining soil that is rich in organic matter. It grows best in slightly acidic soils with a pH range of 5.5 to 6.5, although it can also thrive in neutral soil with a pH of 7.0. The soil should have good water retention capacity, but not be soggy, as the roots of the plant can rot quickly in overly moist soil. It is also essential to make sure the soil does not dry out completely, as this can stress the plant and cause damage.
Cultivation Methods
To successfully cultivate Butyrospermum parkii (G.Don) Kotschy var. poissoni A.Chev., it is crucial to begin by selecting a suitable site for planting. The plant thrives in soil that is well-draining, slightly acidic, and rich in nutrients. Furthermore, it requires plenty of sunlight, which means locating it in an area that receives at least eight hours of direct sunlight daily. When planting, create holes that are twice the size of the plant's root ball to facilitate proper root growth. Cover the plant's root ball with soil and water it immediately after planting to help settle the soil around the roots.Watering Needs
While the Butyrospermum parkii (G.Don) Kotschy var. poissoni A.Chev. plant is drought-tolerant, it requires regular watering for healthy growth and development. Newly-planted specimens will need more water than established ones. Watering should be done deeply once per week, or more frequently during prolonged periods of drought or high temperatures. Be sure to water the plant early in the morning or late in the day to reduce water loss through evaporation. Overwatering should be avoided as it can cause root rot, which can be detrimental to the plant's health.Fertilization
To ensure optimal growth and development, it may be necessary to apply fertilizer to Butyrospermum parkii (G.Don) Kotschy var. poissoni A.Chev. plants. Fertilization should be done during the growing season, primarily in spring and summer, to promote lush foliage growth. A balanced, slow-release fertilizer with a nitrogen-phosphorus-potassium ratio of 10-10-10 or 20-20-20 can be used. Be sure to follow the package instructions regarding application rates and timing carefully.Pruning
Pruning is not often necessary for Butyrospermum parkii (G.Don) Kotschy var. poissoni A.Chev. plants. However, if the plant becomes too large, it may be necessary to prune to maintain size and shape. Pruning should be done in late winter or early spring before new growth emerges. Use sharp, sterile pruning shears to make clean cuts, and be sure to remove dead or damaged branches first. The ideal time to prune is when the plant is dormant, as it helps to reduce stress on the plant.Propagation of Butyrospermum parkii (G.Don) Kotschy var. poissoni A.Chev.
The Butyrospermum parkii (G.Don) Kotschy var. poissoni A.Chev., commonly known as African shea butter tree, is commonly propagated both by seeds and vegetative methods. Propagation is best carried out during the rainy seasons.
Propagation by seeds
The most common method of propagating Butyrospermum parkii (G.Don) Kotschy var. poissoni A.Chev. is by seeds. The seeds are collected from mature fruits that fall from the tree in the months of May to June. It is important that the fruit is mature before the collection of the seeds. The seeds should be removed from the fruit and cleaned of any fleshy material. The seeds should not be allowed to dry out as this may reduce germination rates. Pre-germination treatment, such as soaking the seeds in water overnight, may improve germination rates. The seeds are then sown in well-drained soil under nursery conditions. The seedlings are pricked out into nursery bags or pots once they have reached about 10cm high.
Propagation by vegetative methods
Propagation by vegetative methods involves using stem cuttings or grafts from selected mature trees. Stem cuttings should be taken from the trees during the rainy seasons. The cuttings should be well matured and at least 30cm in length. They should be treated with rooting hormones to encourage sprouting. The cuttings should be planted in well-drained soil under nursery conditions until they develop strong roots. They are then transplanted into the field.
