Appearance
The Celastrus senegalensis Lam. is a shrub or small tree that grows up to 8 meters in height. The leaves are glossy and green, and the branches are slender. The plant produces small, yellowish-green flowers in clusters that bloom from November to February. The fruit is a capsule that contains one or two seeds.
Uses
Celastrus senegalensis Lam. has various traditional uses in West African medicine. The stem bark and roots of the plant are used to treat fever, malaria, snakebites, and stomach pains. The leaves are used as a laxative and to treat diarrhea. The seeds are also used as a medicine for various ailments.
In addition to its medicinal properties, the plant has economic value as well. The oil extracted from the seeds is used in traditional soap-making, and the seeds themselves are edible and used for cooking. The wood of the plant is used for carving and making tools.
Light requirements
Celastrus senegalensis Lam. is a plant that requires full sun exposure to thrive. It needs to be exposed to direct sunlight for at least 6 hours a day to ensure healthy growth and development. The plant may survive in partially shaded areas, but it will not grow as vigorously as it would in full sun exposure.
Temperature requirements
The plant can tolerate a wide range of temperatures. However, it grows best in warm temperatures within the range of 20-35°C (68-95°F). It can also grow in cooler temperatures but may experience slow growth rates. Celastrus senegalensis Lam. cannot survive in extreme temperatures such as frost or very high temperatures beyond 40°C (104°F).
Soil requirements
Celastrus senegalensis Lam. grows best in well-draining soils that are rich in organic matter. The soil should be slightly acidic with a pH range of 5.5 to 6.5. The plant prefers sandy loam soils that are not waterlogged. It can also grow in clay soils, but it requires good drainage to prevent root rot. The plant is also tolerant of soils that are poor in nutrients, but it responds well to regular application of fertilizers.
Cultivation of Celastrus senegalensis Lam.
Celastrus senegalensis Lam. can be grown from seeds or stem cuttings. Take the cuttings from young, healthy plants or from the tips of established ones.
The plant is tolerant to a wide range of soil types, but it prefers well-draining, nutrient-rich soil. It can grow both in full sun and partial shade, so it can be suitable for varying growing conditions.
It is best to grow the plant in a warm and humid climate where the temperature does not fall below 10° C. The plant cannot tolerate frost or extreme cold climatic conditions, and it dies at temperatures below -4° C.
Watering Needs of Celastrus senegalensis Lam.
The plant needs regular watering during the growing season. Water the plant once a week or when the soil dries out during the dry months. Avoid overwatering, as it could lead to root rot. Water the plant less frequently during the winter months.
You can also mist the foliage regularly to maintain the humidity levels required by the plant. This will also help prevent spider mites from infesting the plant.
Fertilization of Celastrus senegalensis Lam.
Celastrus senegalensis Lam. requires regular feeding during the growing season. Use a balanced, well-diluted fertilizer once a month from spring until early fall. Use a liquid fertilizer with an NPK ratio of 10-10-10 or 20-20-20. Reduce the fertilizer frequency during the winter months.
Avoid fertilizing the plant during its dormant period as this could cause damage to the roots and may affect the growth and health of the plant.
Pruning of Celastrus senegalensis Lam.
Pruning Celastrus senegalensis Lam. is essential to limit its size and promote bushy growth. Prune the plant during its dormant period, which is usually during the winter months. Remove any weak or diseased branches. Prune the tips of the branches to encourage bushy growth.
Avoid over-pruning the plant, as this could limit the flowering of the plant. Use sharp pruning shears and make clean cuts to prevent damage to the plant.
Propagation of Celastrus Senegalensis Lam. Plant
Celastrus Senegalensis Lam. can be propagated through various methods, including:
Seed Propagation
This method involves planting seeds directly into the soil. The seeds should be collected in the dry season after the fruit has matured and turned brown. The seeds should be cleaned, treated with hot water at around 70°C for 10-15 minutes to break dormancy and then soaked in cold water for 24 hours. After this, the seeds should be planted 2-3cm deep in well-prepared soil in raised beds or in containers. Germination begins in around 10-14 days. The seedlings can later be transplanted into the field after 3-4 months.
Air Layering
Air layering is an asexual propagation method that involves making a cut at the selected plant's point, but the bark is not completely severed. A ball of moss mixed with rooting hormone is wrapped around the cut area and then covered with plastic to maintain moisture. Once roots start to develop, the shoot can be cut from its parent plant and transplanted. Air layering should be done during the dry season for better results.
Cutting Propagation
This method involves taking stem cuttings of about 20-30cm long from the parent plant during the dry season. These cuttings are then treated with hormone rooting powder and planted in a mixture of sand and soil in a rooting medium. The propagating cuttings should be kept moist and shaded with clear plastic until roots appear, which usually takes 6-8 weeks.
Budding or Grafting
Buds or scions can be taken from the desired parent plant and grafted onto rootstock of the same species. Grafting is usually done during the rainy season, minimizing the likelihood of the plant drying out or experiencing shock.
Whichever method is chosen, proper care and management of the young plants are essential to ensure their survival and healthy growth.
Disease Management for Celastrus senegalensis Lam.
Celastrus senegalensis Lam. is susceptible to several diseases that can compromise its health and productivity. It is important to monitor the plant regularly and employ appropriate management measures to prevent and control diseases. Some common diseases that affect Celastrus senegalensis Lam. Include:
- Anthracnose: This fungal disease causes leaf spots, wilting, and cankers on the stems and fruits of the plant. To manage anthracnose, it is important to maintain proper sanitation practices, prune affected branches, and apply fungicides such as copper-based sprays or sulfur.
- Leaf spot: This disease causes yellowing, spotting, and premature leaf drop. It is caused by a fungus and can be managed by removing affected plant parts, applying fungicides, and maintaining proper plant spacing and airflow.
- Powdery mildew: This fungal disease causes a white powdery growth on the leaves, stems, and fruits of the plant. To control powdery mildew, it is important to remove affected plant parts, improve air circulation, and apply fungicides such as sulfur or neem oil.
Pest Management for Celastrus senegalensis Lam.
Celastrus senegalensis Lam. is also susceptible to pest infestations, which can cause significant damage to the plant and reduce its yield. Some common pests that attack Celastrus senegalensis Lam. Include:
- Mealybugs: These soft-bodied insects feed on the sap of the plant and can cause yellowing, stunting, and leaf drop. To manage mealybugs, it is important to maintain proper sanitation practices and apply insecticides such as neem oil or insecticidal soap.
- Aphids: These small insects also feed on plant sap and can cause stunted growth and curled leaves. They can be controlled by spraying the plant with water or insecticidal soap.
- Mites: These tiny arachnids feed on the underside of leaves, causing yellowing, bronzing, and leaf drop. To control mites, it is important to maintain proper plant hygiene, such as removing debris and weeds, and applying miticides such as sulfur.
It is important to monitor Celastrus senegalensis Lam. regularly and employ appropriate management measures to prevent and control diseases and pests. Proper planting, watering, and feeding practices can also help to promote the health and vigor of the plant.
