Overview
Butyrospermum parkii (G.Don) Kotschy var. parvifolia A.Chev. is a species of the Shea tree, a member of the Sapotaceae family. It is commonly known as the dwarf shea tree or West African butter tree. The plant is native to West Africa, particularly the savannas of Mali, Burkina Faso, Ghana, Togo, and Benin.
Appearance
The dwarf shea tree is a small to medium-sized tree that can grow up to 15 meters tall with a trunk diameter of up to 50 cm. The tree has a rounded crown and a deep taproot system that can reach up to 15 meters in depth, helping the tree withstand droughts and other harsh conditions. The leaves are alternate, compound, and evergreen, with each leaflet being 2-7 cm long and 1-3 cm wide. The flowers of the dwarf shea tree are small and whitish-yellow in color and are arranged in spherical inflorescences. The fruit, known as the shea fruit, is a green or yellowish berry-like drupe that contains a single seed.
Uses
The dwarf shea tree is primarily known for the butter produced from its seeds, which is commonly known as shea butter. Shea butter is widely used in cosmetics, soaps, and skincare products due to its moisturizing and anti-inflammatory properties. It is also used in traditional medicine to treat various skin conditions, including eczema, dermatitis, and acne. The bark of the dwarf shea tree is used for medicinal purposes, such as treating colds, diarrhea, and dysentery. The wood of the tree is used for fuel, charcoal, and for making furniture and other household items.
In addition to its economic and medicinal values, the dwarf shea tree is an important source of shade and shelter for animals, and its leaves and fruits provide food for various herbivores, including elephants, antelopes, and baboons. The tree is also important for soil conservation, as its deep-rooted system helps prevent erosion, and its leaf litter improves soil fertility.
Light Requirements
Butyrospermum parkii (G.Don) Kotschy var. parvifolia A.Chev. grows best in direct sunlight, but it can also tolerate partial shade. When grown in full shade, the plant tends to lose its leaves and grow weakly. Therefore, it is recommended to grow the plant in an area that receives at least six hours of direct sunlight per day.
Temperature Requirements
The Butyrospermum parkii (G.Don) Kotschy var. parvifolia A.Chev. plant is native to Africa and usually grows in areas with a warm and humid climate. It requires a minimum temperature of 18°C (64°F) to grow properly. During the colder months, it is recommended to bring the plant indoors to keep it warm.
Soil Requirements
The Butyrospermum parkii (G.Don) Kotschy var. parvifolia A.Chev. plant prefers well-draining, sandy, and loamy soil. It cannot tolerate waterlogged or poorly-drained soil. A soil pH of 6.0 to 7.5 is ideal for the plant to grow. Adding organic matter such as compost to the soil can help improve its fertility and water-holding capacity, which will benefit the plant's growth.
Cultivation Methods
Butyrospermum parkii (G.Don) Kotschy var. parvifolia A.Chev. is native to the African continent and is commonly known as the shea tree. The plant requires warm temperatures and grows best in tropical or subtropical regions. It thrives in well-drained soil and requires full sun exposure for optimal growth.
The best time to plant shea tree seeds is during the hot summer months when temperatures are high. The seeds should be planted in a well-prepared bed that is free of weeds and other competing plants. The depth of planting should be 2-3 cm below the soil surface.
Watering Needs
Shea trees are moderately drought tolerant and can survive long periods without water. However, to ensure optimal growth and yield, the plant should receive adequate water. The frequency of watering depends on the soil type and the stage of plant growth.
During the early stages of growth, the plant should be watered frequently to encourage deep root growth and canopy development. As the plant matures, the frequency of watering can be reduced to once or twice a month.
Fertilization
Shea trees require regular fertilization to ensure optimal growth, yield, and nut quality. The best time to apply fertilizer is during the rainy season when the plant is actively growing. It is recommended to use organic fertilizers, such as compost or manure, to improve the soil's nutrient content and support healthy growth of the plant.
The amount of fertilizer required depends on the soil type and nutrient content. A soil analysis can help determine the appropriate type and amount of fertilizer to apply.
Pruning
Pruning is essential to maintain the plant's shape and promote healthy growth. Shea trees should be pruned immediately after planting to remove any damaged or weak branches. After that, pruning should be done once a year to remove any dead, diseased, or damaged branches.
Pruning should be done during the dry season to avoid exposing the plant to fungal infections. It is recommended to sterilize pruning tools before use to prevent the spread of diseases.
Propagation of Butyrospermum parkii var. parvifolia
Butyrospermum parkii var. parvifolia, also known as small-leaved shea, is a tree species that belongs to the Sapotaceae family. It is native to West Africa and has important economic value due to its shea butter production.
Seed Propagation
One of the common methods of propagating Butyrospermum parkii var. parvifolia is through seed propagation. The seeds are collected from mature fruits after they have fallen to the ground. The collected seeds have to be cleaned and sown immediately for best results. The seeds do not have a long shelf life and should not be allowed to dry out.
The seeds should be sown in a well-draining planting medium, preferably a mixture of loamy soil and sand in a ratio of 2:1. The seeds should be sown at a depth of 2 cm and kept moist but not water-logged. The ideal germination temperature is between 25-30°C. Germination can take up to 3 months, after which the seedlings should be transplanted into bigger containers.
Vegetative Propagation
Butyrospermum parkii var. parvifolia can also be propagated vegetatively. One of the commonly used methods is through rooting of stem cuttings. The stem cuttings should be collected from healthy and mature trees during the dormant season.
The cuttings should be about 20-30 cm long and stripped of all leaves except for the top three. The cuttings should be dipped in rooting hormone and planted in well-draining soil mix. A humidity dome should be placed over the cuttings to maintain high humidity levels. The cuttings should root in about 4-6 weeks, after which they can be transplanted to their permanent positions.
Grafting is also a possible method for propagating Butyrospermum parkii var. parvifolia, but it is not commonly used due to the difficulty in achieving high success rates.
