Chassalia subochreata (De Wild.) Robyns is a species of plant that belongs to the Rubiaceae family. It is commonly found in tropical regions of Africa, specifically in Angola, Cameroon, and Gabon.
Common Names
Chassalia subochreata is commonly known as 'Amour en cage' in French, which translates to 'Love in a cage.' It is also known as 'Maman Tasson' in the Bakongo language.
Uses
Chassalia subochreata has various medicinal uses in traditional African medicine. The roots of the plant are boiled and taken orally as a treatment for various ailments such as stomach ulcers, fever, and chest infections. The plant also has antimalarial properties, and the leaves are used as a poultice to treat wounds and skin infections.
In addition to its medicinal uses, Chassalia subochreata is used in the production of natural dyes. The plant's fruit produces a yellow dye that is used to dye textiles in some African communities.
General Appearance
Chassalia subochreata is a small shrub that can grow up to 2 meters in height. The plant has glossy leaves that are oval in shape and can grow up to 13 cm in length. The flowers of Chassalia subochreata are small, white, and star-shaped. The plant produces fruit that is orange to red in color and is 2.5 cm in diameter.
The fruit of the plant is unique in appearance, resembling a small, decorative cage. The bright colors and unusual shape of Chassalia subochreata's fruit have made it a popular ornamental plant in gardens and parks in some parts of the world.
hereLight Requirements
Chassalia subochreata typically thrives in filtered or partially shaded sunlight. It cannot withstand harsh direct exposure to sunlight, as it may cause leaf scorching or browning. Therefore, it is recommended to place it in an area where it can receive about 50% to 70% shade.
Temperature Requirements
Chassalia subochreata prefers warm temperatures between 20°C to 30°C. It cannot tolerate frost or extremely low temperatures, as it can lead to leaf damage or death. Therefore, it is essential to keep the plant in a warm environment, and even during colder seasons, a minimum temperature of 15°C is necessary for its survival.
Soil Requirements
The Chassalia subochreata prefers well-draining soils that are slightly acidic, with a pH range of 4.5 to 6.5. It thrives in moist soil conditions; however, it cannot tolerate waterlogging as it may cause root rotting. Therefore, a well-draining soil mixture is recommendable, preferably a blend of peat moss and perlite or sand. Additionally, occasional fertilization with a low nitrogen fertilizer can stimulate healthy growth and development.
Cultivation Methods
Chassalia subochreata is a tropical plant that thrives in warm, humid conditions. It is best grown in well-draining soil with high organic matter content. The plant prefers partial shade and must be protected from direct sunlight. It is highly adaptable and can grow in different soil types, including loamy, sandy, and clay soils.
Watering Needs
The plant requires consistent watering to promote healthy growth. Watering should be done when the soil feels dry to the touch. The soil should be moist but not waterlogged, as excess water can lead to root rot.
Fertilization
Regular fertilization is crucial for the optimal growth and development of Chassalia subochreata. The plant needs a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Fertilizing should be done during the growing season, and the frequency will depend on several factors, including soil type, temperature, and humidity.
Pruning
Pruning is essential for maintaining the shape and size of the plant. Dead, damaged, or diseased leaves and stems should be removed as soon as possible to prevent the spread of infections. To encourage growth, pruning should be done after flowering, and only a third of the plant should be removed at one time.
Propagation of Chassalia subochreata
Chassalia subochreata is a plant that can be propagated through various methods including seeds, stem cuttings, and layering.
Propagation from Seeds
The plant's seeds can be collected and used for propagation. The seeds should be collected when they are mature and plump. They can be sown in seed trays with well-draining soil and kept in a warm and humid place. It takes around 14 to 30 days for the seeds to germinate. After they have germinated, they can be transplanted into individual containers and grown until they are mature enough to be planted in the ground.
Propagation from Stem Cuttings
Chassalia subochreata can also be propagated from stem cuttings. The stem cutting should be 6 to 8 inches long and have at least two leaves. The lower leaves should be removed, and the cutting should be planted in well-draining soil. The soil should be kept moist, and the cutting should be kept in a warm and humid place. It takes around 3 to 4 weeks for the stem cutting to root. After it has rooted, it can be transplanted into individual containers and grown until it is mature enough to be planted in the ground.
Propagation from Layering
Layering is another propagation method for Chassalia subochreata. It involves bending a low-hanging stem to the ground and burying a small portion of it in the soil. The buried part of the stem will develop roots, and a new plant will form. Once the newly formed plant is established, it can be separated from the parent plant and planted in the ground.
Disease and Pest Management for Chassalia subochreata (De Wild.) Robyns
Chassalia subochreata, commonly known as the African coffee plant, is a member of the Rubiaceae family. This species is susceptible to various diseases and pests that affect its growth and yield. Here are some of the common diseases and pests that can affect Chassalia subochreata and ways to manage them.
Diseases
Bacterial blight, leaf spot, and black pod disease are the most common diseases that affect Chassalia subochreata plants.
Bacterial blight: This bacterial disease affects the leaves and stems of the plant, causing them to wilt and turn brown. Proper sanitation practices, such as removing infected plant material and disinfecting tools, can help prevent the spread of bacterial blight. Copper-based fungicides are effective in controlling the disease.
Leaf spot: Leaf spot is caused by the fungi from the genus Helminthosporium and causes small brown spots on the leaves. Removing infected plant material and minimizing the humidity level through proper ventilation can help prevent the spread of the disease. Fungicides such as chlorothalonil are effective in controlling leaf spot.
Black pod disease: This fungal disease causes black spots on the pods, which eventually turn mushy and fall off. Sanitation practices, such as removing infected pods and fallen leaves, can help prevent the spread of black pod disease. Fungicides containing copper can also be used to control the disease.
Pests
The African coffee plant is susceptible to pests such as mites and whiteflies.
Mites: Mites are tiny pests that suck the sap out of the plant, causing the leaves to turn yellow and lose their vigor. To manage mites, it is important to maintain a healthy plant by providing adequate nutrients and water. Insecticidal soaps can also be used to control the pest.
Whiteflies: Whiteflies are small winged insects that suck the sap out of the plant, causing yellowing and wilting of the leaves. They also secrete honeydew, which attracts ants and can promote the growth of mold. Yellow sticky traps and insecticidal soaps are effective in controlling whiteflies.
Regular inspection of the plants and the implementation of appropriate management strategies can help minimize the damage caused by pests and diseases in Chassalia subochreata.
