Overview
Cephaelis debauxii, also known as Debaux's coffee, is a tropical plant species of the Rubiaceae (coffee family). It is native to Central and West Africa, including Cameroon, Congo, Gabon, and the Central African Republic.
Appearance
The plant is a shrub or small tree, reaching up to 10 meters in height. It has broad leaves that are 10-20 cm long and 5-10 cm wide. The flowers of Cephaelis debauxii are white or yellowish and have a tubular shape.
Common Names
Cephaelis debauxii is commonly known as Debaux's coffee, abangazamugweri (in the Kikongo language), and abangatembe (in the Lingala language).
Uses
The leaves and bark of Cephaelis debauxii are used in traditional medicine to treat various illnesses, such as malaria, fever, diarrhea, and respiratory infections. The plant contains alkaloids, including cephaeline and emetine, which have been shown to have antimalarial and antimicrobial properties.
In addition to its medicinal properties, some people use the plant for ornamental purposes, as its attractive foliage and flowers make it a beautiful addition to gardens and landscapes.
Light Requirements
Cephaelis debauxii requires bright, indirect light in order to grow properly. Direct sunlight can scorch the plant's leaves and cause damage. If grown indoors, placing the plant near a window that receives bright, indirect light is ideal.
Temperature Requirements
The optimal temperature range for Cephaelis debauxii growth is between 18 to 24°C (64 to 75°F). The plant is sensitive to extreme variations in temperature and should be shielded from hot or cold drafts. It is best to maintain a stable, moderate temperature for the plant to thrive.
Soil Requirements
The growth of Cephaelis debauxii is greatly dependent on the type of soil the plant is growing in. Cephaelis debauxii prefers a well-draining soil that is rich in organic material. The soil PH should be mildly acidic or neutral. The plant should be watered when the top 1-2 inches of soil are dry and proper drainage is necessary to prevent the roots from becoming waterlogged.
Cultivation Methods
Cephaelis debauxii is native to tropical Africa and can grow up to six feet tall. It prefers to grow in partial shade with well-draining soil that is rich in organic matter. It can also tolerate full sun and survive in various soil types as long as it is well-draining.
The plant can be propagated by stem cuttings or seeds. When propagating from stem cuttings, make sure to use a node, as this is where roots will form. Cuttings should be taken in the summer and planted in a well-draining potting mix with bottom heat (around 70-75°F) and a high level of humidity.
Watering Needs
Cephaelis debauxii prefers to grow in moist soil but not waterlogged. Water the plant thoroughly when the top 1-2 inches of soil feels dry. Overwatering can lead to root rot and cause the leaves to turn brown and fall off. It is essential to maintain consistent moisture levels throughout the growing season.
Fertilization
This plant needs moderate fertilization. Use a balanced fertilizer with a 10-10-10 ratio every two weeks during the growing season. It would help if you stopped fertilizing in the winter when the plant goes into its dormancy phase.
Pruning
Cephaelis debauxii requires pruning to maintain its shape and size. You can prune the plant back in the spring or early summer before the growing season starts. Do not prune during the winter when the plant is dormant. Use clean, sharp shears to make cuts above a leaf node, and do not remove more than one-third of the plant's growth in a single season.
Propagation of Cephaelis debauxii
Cephaelis debauxii (De Wild. ex Schnell) Schnell, commonly known as African coffee, is a shrub indigenous to central and west Africa. It belongs to the Rubiaceae family and is popularly cultivated for its medicinal properties. Propagation of Cephaelis debauxii can be achieved using three methods: seeds, stem cuttings, and layering.
Propagation by seeds
The most common method of propagating Cephaelis debauxii is through seeds. The ideal time for planting is at the onset of the rainy season or after the last frost in the spring. The seeds should be planted in a well-draining soil mix, and the planting depth should be about 1 cm. The seeds should be moistened regularly, and within two to three weeks, they will germinate. Once they have grown to about 5 cm, they can be transplanted to their permanent location.
Propagation by stem cuttings
Propagation of Cephaelis debauxii by stem cutting is another method. The ideal time for taking cuttings is during the wet season when the plant is actively growing. The cuttings should be at least 10 cm long and should have at least three to four nodes. Remove the bottom leaves and dip the cuttings into a rooting hormone. Insert the cuttings into a well-draining soil mix, keeping the soil moist but not too wet. The cuttings should develop roots within four to six weeks and can then be transplanted to their permanent location.
Propagation by layering
Propagation by layering is another method for Cephaelis debauxii. This technique is useful for plants with low branching like Cephaelis debauxii. Choose a low horizontal stem and wound the lower side of the stem. Make a small hole in the soil and insert the wounded part of the stem into the soil. Secure the stem with a wire or peg and wait for the new root to develop. Once the roots have developed, cut the stem from the parent plant and transplant it into its permanent location.
Propagation of Cephaelis debauxii is relatively easy, and any of these three methods can be employed. The plant prefers a well-draining soil, partial shade, and regular watering.
Disease and Pest Management for Cephaelis debauxii (De Wild. ex Schnell) Schnell
Cephaelis debauxii is a tropical plant species that is commonly referred to as coffee of Guinea. Being a plant species, it is not immune to disease and pest infestations that can significantly impact its health and productivity. It is, therefore, imperative to have comprehensive knowledge of the common diseases and pests that affect the plant and ways to manage them proactively.
