Light Requirements
Uvariopsis zenkeri Engl. plants require bright, indirect light. A spot near a window or an area with filtered light is ideal. Avoid direct sunlight as it can scorch the leaves and stunt plant growth.
Temperature Requirements
The ideal temperature range for Uvariopsis zenkeri Engl. is between 18°C to 26°C (65°F-80°F). Avoid exposing the plant to temperatures below 15°C (59°F) as it can cause the plant to die.
Soil Requirements
These plants prefer well-draining soil that is rich in nutrients. Therefore, a mixture of peat moss, perlite, and vermiculite is ideal. Do not use heavy soils that retain water for too long, as it can lead to root rot.
Cultivation Methods
Uvariopsis zenkeri Engl. is a tropical plant that thrives in warm and humid conditions. It prefers well-draining and loamy soil and needs to be potted in a container with drainage holes to avoid waterlogging. The plant requires adequate sunlight to grow well; however, it should be protected from direct sunlight as it can lead to leaf scorching and discoloration. The ideal temperature for the plant's growth is between 20°C to 28°C.
Watering Needs
The Uvariopsis zenkeri Engl. plant requires regular watering to maintain its growth and health. However, it is essential to ensure that the soil is not waterlogged as it can lead to root rot. The frequency of watering depends on the weather conditions, and it should be watered more frequently in hot and dry weather. Watering should also be reduced during the winter season when the plant goes into dormancy. To ensure the soil stays moist and not waterlogged, it is better to water the plant moderately.
Fertilization
The Uvariopsis zenkeri Engl. plant requires regular fertilizer applications to keep its leaves green and healthy. Fertilization should be done during the growing season, which is in spring and summer. You can use a balanced fertilizer for the plant as it needs a moderate amount of both nitrogen and phosphorus. Avoid using a fertilizer that contains too much nitrogen as it can lead to leaf discoloration and affect the plant's growth and health. When applying, mix the fertilizer with water and apply the solution in the soil around the plant.
Pruning
Pruning the Uvariopsis zenkeri Engl. plant is not mandatory, but it is advisable to do so during the growing season. The plant needs to be pruned for two reasons; removal of dead or yellow leaves, and to maintain its shape and size. When pruning, use a sharp pruning tool to avoid damaging the plant and cut off the dead leaves or branches. You can also trim the plant's tips to encourage bushier growth and keep it compact.
Propagation of Uvariopsis zenkeri Engl.
Uvariopsis zenkeri Engl., commonly known as the "African cherry", is an evergreen tree that can be propagated through several methods. The plant produces small, almond-like fruits that contain seeds which can be sown to grow new plants.
Seed Propagation
Seed propagation is the most common method used to propagate Uvariopsis zenkeri. Collect the fruits from the plant when they are ripe, and extract the seeds. These seeds can be sown immediately or stored for later use. Sow the seeds in a mixture of potting soil, sand, and compost, and water the soil regularly. Keep the soil moist and warm, at a temperature range of 20-26 °C, and the seeds will germinate in two to four weeks.
Cutting Propagation
Another way of propagating Uvariopsis zenkeri is through stem cutting. Take a 10 to 15 cm cutting from the new growth of the plant and remove the lower leaves to expose at least two nodes. Dip the cut end of the stem into a rooting hormone and plant it in a mixture of equal parts of peat and sand. The cutting requires high humidity, so cover it with a plastic bag to create a mini greenhouse. Keep the soil moist and wait for the cutting to root. This process can take up to six weeks.
Air Layering Propagation
Air layering is another option for propagating Uvariopsis zenkeri. This technique is best used on mature plants. Select a branch and remove the bark around a small section where the roots will form. This encourages the growth of new roots. Cover the exposed part of the bark with moist sphagnum moss, and wrap it in plastic to create a humid environment. After several weeks, roots will develop, which can be cut from the branch and potted up.
Regardless of the chosen method, propagating Uvariopsis zenkeri requires patience and careful attention to the plant's needs.
Disease and Pest Management for Uvariopsis zenkeri Engl.
Uvariopsis zenkeri Engl. is a tropical evergreen shrub that is generally hardy and disease-resistant. However, like all plants, it is still susceptible to certain diseases and pests.
Common Diseases
One of the most common diseases to affect Uvariopsis zenkeri Engl. is black spot, which appears as circular black or brown spots on the leaves. This is caused by a fungus and can be treated with a fungicide. Another fungal disease that can affect this plant is powdery mildew, which appears as a white powdery coating on the leaves. This can also be treated with fungicide.
If the leaves of Uvariopsis zenkeri Engl. start to yellow and drop off, this could be a sign of root rot. This is caused by over-watering or poor drainage and can be prevented by ensuring the plant is not sitting in water and avoiding over-watering.
Common Pests

They can be removed by wiping the leaves with a damp cloth or with insecticidal soap. Another common pest is the spider mite, which appears as tiny red or brown insects on the undersides of leaves. They can be treated with insecticidal soap.
Preventative Measures
To prevent disease and pest problems with Uvariopsis zenkeri Engl., it is important to keep the plant in good health. This means ensuring it is planted in well-draining soil and avoiding over-watering. Regularly inspect the plant for pests and diseases and take action immediately if any are found.
