It cannot tolerate frost or freezing temperatures, and its growth rate is significantly affected by cold weather. The ideal temperature range for this plant is between 20°C to 30°C (68°F to 86°F).
Soil Requirements
The Beilschmiedia auriculata Robyns & R.Wilczek plant prefers well-draining, fertile soils. It can grow in a variety of soil types, including sandy, loamy, and clay soils, as long as they are well-draining. The soil pH should be slightly acidic to neutral, with a range between 5.5 to 7.5 for optimal growth.
It is important to note that the plant will not grow well in waterlogged soils, and proper drainage is essential to avoid root rot. This plant can also benefit from regular fertilization with balanced nutrients to support its growth and development.
Cultivation methods
Beilschmiedia auriculata Robyns & R.Wilczek plant prefers warm and damp climates. You can plant this tree in the open ground or in a large pot, in a sunny, semi-shaded area with fertile soil. To enhance the growth of the plant in your garden soil, you can add compost or well-decomposed manure at planting time.
Watering needs
The plant requires regular watering for a healthy growth, especially during the dry seasons. You can water the plant on a regular basis to keep the soil moist, but avoid oversaturating the soil as it can lead to root rot. Check the soil moisture level before watering the plant, and only water when the top layer of soil feels dry to the touch.
Fertilization
Beilschmiedia auriculata Robyns & R.Wilczek requires regular fertilization to enhance its growth. You can apply nutrient-rich fertilizers every two weeks, starting from the beginning of the growing season until the end of summer. During winter, you can feed the plant only once per month. Use a slow-release fertilizer and follow the manufacturer's instructions for proper mixing and application.
Pruning
To keep your Beilschmiedia auriculata Robyns & R.Wilczek plant in good shape, you can prune it occasionally.

Remove any damaged, dead, or diseased branches and cut back any overgrown branches to stimulate new growth. You can also prune to shape the plant for aesthetic purposes.
Propagation of Beilschmiedia auriculata Robyns & R.Wilczek
Beilschmiedia auriculata Robyns & R.Wilczek is a fast-growing evergreen tree that can reach up to 20 meters in height. Native to Central and West Africa, this tree is commonly propagated through seeds and cuttings.
Propagation through Seeds
Seeds of Beilschmiedia auriculata Robyns & R.Wilczek can be collected from mature fruits in the wild or purchased from certified seed suppliers. The seeds should be cleaned and soaked for 24 hours in water before sowing. To ensure successful germination, it is recommended to plant the seeds in a well-draining soil mix at a depth of 1-2 cm. The soil should be kept moist but not waterlogged, and the seeds should be placed in a warm and humid environment with filtered sunlight. Germination can occur within 2-4 weeks.
Propagation through Cuttings
Beilschmiedia auriculata Robyns & R.Wilczek can also be propagated through cuttings taken from mature trees. The best time to take cuttings is during the rainy season when the tree is actively growing. Cuttings should be taken from semi-hardwood branches, approximately 15-20 cm long and with at least two nodes. The bottom node should be partially stripped of leaves and dipped in a rooting hormone powder. The cuttings should then be planted in a well-draining soil mix and kept in a warm and humid environment with filtered sunlight. Rooting can occur within 6-8 weeks.
Overall, both seed and cutting propagation methods can be successful for Beilschmiedia auriculata Robyns & R.Wilczek. However, care should be taken to ensure that the plants are provided with the appropriate growing conditions, including adequate water, sunlight, and nutrients.
Disease and Pest Management for Beilschmiedia auriculata Robyns & R.Wilczek
Beilschmiedia auriculata, also known as the African walnut, is a species of tree that grows primarily in tropical and subtropical areas of Africa. While it is generally a hardy plant, there are several pests and diseases that can affect its growth and health. Here are some common issues and management strategies:
Common Pests
Caterpillars: Caterpillars can cause significant damage to Beilschmiedia auriculata leaves, feeding on them and causing defoliation. To manage this pest, manually remove any caterpillars you see or spray the plant with a natural insecticide like neem oil.
Aphids: Aphids are small, pear-shaped insects that feed on the sap of plants, causing leaves to turn yellow and wilt. You can manage these pests by spraying the plant with a gentle stream of water, introducing natural predators such as ladybugs, or applying an insecticidal soap.
Beetles: Several species of beetles can be a problem for Beilschmiedia auriculata, including the ambrosia beetle and the twig beetle. These pests usually bore into the branches or trunk of the tree, causing damage to its vascular system. To manage them, prune any affected branches and dispose of them promptly.
Common Diseases
Leaf Spot: Leaf spot is a fungal disease that causes brown spots to appear on the leaves of Beilschmiedia auriculata. To manage this disease, remove any affected leaves and avoid overhead watering, which can encourage the spread of fungal spores.
Powdery Mildew: Powdery mildew is a fungal disease that causes a white, powdery substance to appear on the leaves of plants. To manage this disease, apply a fungicide to the plant every two weeks until the infection clears up.
Root Rot: Root rot is a serious fungal disease that can kill Beilschmiedia auriculata. This disease is usually caused by overwatering or poorly draining soil. To manage root rot, improve the drainage of the soil by adding mulch or compost and avoid overwatering.
By implementing these pest and disease management strategies, you can help to ensure that your Beilschmiedia auriculata stays healthy and vibrant.
