Lonchocarpus scheffleri Harms ex Baker f. responds well to organic fertilizers such as compost, manure, and worm castings. Alternatively, use a slow-release granular fertilizer with a balanced ratio of nitrogen, phosphorus, and potassium. The plant should be fertilized during the growing season from spring to fall, with a reduced frequency during winter or a complete stop altogether.
Pruning
Pruning is not necessary for the plant to grow. However, pruning can be done to shape the plant or remove dead or damaged branches. Pruning is best done during the winter or early spring when the plant is dormant. Use sterilized pruners to avoid infecting the plant with disease.
Propagation of Lonchocarpus scheffleri Harms ex Baker f.
Lonchocarpus scheffleri Harms ex Baker f. is a tropical tree species native to several African countries, such as Cameroon, Congo, and Gabon. The plant belongs to the Fabaceae family and has several common names, including "monkey cutlass," "sword bean," and "firewood tree." The tree usually reaches a height of 15-20 meters and produces large compound leaves and yellow flowers.
Propagation Methods
There are several ways to propagate Lonchocarpus scheffleri Harms ex Baker f. Depending on the availability of resources and the desired outcome, one can choose from the following methods:
Seed Propagation
Seed propagation is the most common method for propagating Lonchocarpus scheffleri Harms ex Baker f. and other plant species. This method requires collecting mature and viable seeds from healthy and genetically diverse plants. The collected seeds must be cleaned, disinfected, and soaked in water for several hours to stimulate germination.
Afterward, the seeds can be planted in individual pots or seed trays filled with a well-draining and nutrient-rich potting mix. The pots/trays should be kept in a warm and humid place with filtered light, and the soil should be watered regularly but not overwatered. Once the seedlings reach a certain size, they can be transplanted into larger pots or directly into the ground.
Cuttings Propagation
Cuttings propagation is another method for propagating Lonchocarpus scheffleri Harms ex Baker f. This method requires taking semi-hardwood cuttings from healthy and mature plants during the growing season. The cuttings should be about 15-20 cm long and have 3-4 nodes, and their leaves should be trimmed to reduce water loss.
The cuttings can be dipped in a rooting hormone powder and planted in a well-draining and moist rooting medium, such as perlite or vermiculite. The medium should be covered with a plastic bag or dome to create a humid environment and promote rooting. The cuttings should be kept in a warm and bright place but away from direct sunlight. Once the roots have formed and new shoots have emerged, the cuttings can be transplanted into larger pots or directly into the ground.
Air Layering Propagation
Air layering propagation is a less common but effective method for propagating Lonchocarpus scheffleri Harms ex Baker f. This method requires selecting a healthy and mature branch from the parent plant and making a slanting cut on its bark. The cut should be about 2-3 cm long and expose the cambium layer.
The cut should be covered with a layer of damp sphagnum moss or peat and wrapped with a plastic bag or aluminum foil to create a mini greenhouse. The moss/peat should be kept moist, and the bag/foil should be checked regularly for condensation and air exchange. Once the root system has developed, the branch can be cut from the parent plant and transplanted into a separate pot or directly into the ground.
Disease and Pest Management for Lonchocarpus scheffleri Harms ex Baker f.
Lonchocarpus scheffleri Harms ex Baker f., commonly known as the African Supple Jack, is a plant species that is susceptible to a number of diseases and pests. Knowing these diseases and pests and how to manage them is important for the optimal growth and health of the plant.
Common Diseases

The disease can be managed by avoiding overhead watering, as well as pruning infected plant parts and using fungicides.
Another disease that can afflict Lonchocarpus scheffleri is anthracnose. Anthracnose infects the leaves, stems, and fruit of the plant, causing sunken, black spots and lesions. Management options involve removing infected plant parts and using appropriate fungicides.
Common Pests
One of the most common pests that can affect Lonchocarpus scheffleri is spider mites. Spider mites are tiny arachnids that can infest the plant and suck the sap, leading to yellowing of the leaves. These pests can be managed by introducing natural predators such as ladybugs or lacewings, using insecticidal soaps, or spraying with neem oil.
Another pest that is notorious for attacking Lonchocarpus scheffleri is the mealybug. Mealybugs can cause stunted growth and yellowing of the leaves by feeding on the plant's sap. Management methods include releasing predatory insects such as ladybugs, pruning off heavily-infested areas, or using neem oil.
Overall, managing the diseases and pests that can affect Lonchocarpus scheffleri involves preventing infestations through proper maintenance practices such as pruning infected plant parts, avoiding overhead watering, and maintaining a clean growing area. When infestations do occur, control measures such as introducing natural predators, using insecticidal soaps or fungicides, or pruning off infected plant parts may help to mitigate damage to the plant.
