Light: Pausinystalia zenkeri W.Brandt grows best in partially shaded areas with filtered sunlight. Direct sunlight can harm the plant, so it should be placed in a location where it can receive bright but indirect light.
Temperature: The ideal temperature range for Pausinystalia zenkeri W.Brandt is between 60°F to 85°F (15°C-29°C). It can tolerate temperatures as low as 50°F (10°C) but may not fare well in extremely cold temperatures or frost.
Soil: Pausinystalia zenkeri W.Brandt prefers well-draining soils that are rich in organic matter. The soil pH should be between 5.0 to 6.5 for optimal growth. It is recommended to add compost or other organic matter to the soil to provide a nutrient-rich environment for the plant.
Water: Pausinystalia zenkeri W.Brandt thrives in moist soil but does not tolerate waterlogging. It is recommended to water the plant deeply once a week, allowing the soil to dry out partially between watering. Overwatering or underwatering can have detrimental effects on the plant health.
Fertilizer: Pausinystalia zenkeri W.Brandt benefits from regular fertilization. A slow-release fertilizer that contains balanced micronutrients and trace elements can be added to the soil during the active growing season. It is important not to over-fertilize the plant, as this can cause the leaves to become unhealthy and may even damage the roots.
Humidity: Pausinystalia zenkeri W.Brandt thrives in high humidity environments. It is important to maintain a humidity level of approximately 60% around the plant. This can be achieved by misting the leaves with water or placing a humidifier in the room where the plant is located.
Cultivation
The Pausinystalia zenkeri W.Brandt plant is relatively easy to grow and is a popular houseplant. It can be grown both indoors and outdoors, provided it gets the right amount of light and water. When planting the Pausinystalia zenkeri W.Brandt, it is important to use well-draining potting soil and a pot with good drainage holes.
Watering needs
The watering needs of the Pausinystalia zenkeri W.Brandt plant vary depending on the time of year and growing conditions. During the growing season, make sure that the soil is consistently moist, but not waterlogged or soggy. In the winter, allow the soil to dry out slightly between waterings, as the plant is in its dormant phase.
Fertilization
To keep your Pausinystalia zenkeri W.Brandt plant healthy and thriving, it is important to fertilize it regularly. Use a balanced, water-soluble fertilizer every two weeks during the growing season. During the winter, reduce how often you fertilize to once a month, or not at all. Be sure to follow the dosage instructions on the fertilizer packaging, as over-fertilizing can harm the plant.
Pruning
Pruning is not typically necessary for the Pausinystalia zenkeri W.Brandt plant, as it naturally grows in a compact and bushy shape. However, if you notice any dead or damaged leaves or stems, it is important to prune them off to maintain the plant's overall health. To do this, clip the dead or damaged area with a pair of clean scissors or pruning shears, making sure to cut just above a healthy leaf node.
Propagation of Pausinystalia zenkeri
Pausinystalia zenkeri, commonly known as African coffee or Congo coffee, is a small evergreen tree native to tropical West and Central Africa. It is primarily propagated through seeds or vegetative cuttings.
Seed propagation
The seeds of Pausinystalia zenkeri have a hard coat that needs to be scarified, either by nicking or soaking in hot water, before sowing. The scarification process helps in breaking down the dormancy and hastens the germination process. Sow the seeds in a well-draining potting mix, cover lightly with soil, and keep the soil moist. The seeds should germinate within 2-3 weeks.
Vegetative propagation
Pausinystalia zenkeri can also be propagated through vegetative cuttings. Select a healthy stem without any flowers or fruits, and make a clean cut below a node. Dip the cut end in rooting hormone and plant it in a pot filled with a well-draining potting mix. Water the cutting thoroughly and cover it with a plastic bag or a clear plastic container to maintain humidity. Keep the soil moist and place the pot in a warm, bright spot, away from direct sunlight. The cutting should root within 4-6 weeks.
Once the cuttings root and start growing, transplant them into individual pots and provide them with regular care. After 6-8 months, the young plants can be transplanted into larger pots or outdoors in a suitable location.

Pest Management
The most common pests that affect Pausinystalia zenkeri W. Brandt include aphids, spider mites, and mealybugs. Aphids are small insects that suck the sap from the leaves and stems of the plant, causing a reduction in growth and the appearance of yellow spots on the leaves. Spider mites are also small insects that live on the undersides of the leaves and cause a yellow discoloration of the leaves. Mealybugs are white, cottony insects that suck sap from the plant and cause a general decline in the plant's health.
Disease Management
To control leaf spot, remove and destroy any infected leaves and apply a copper-based fungicide. For powdery mildew, remove any infected parts of the plant and apply a sulfur-based fungicide. To treat root rot, remove any affected parts of the plant and transplant into fresh soil that is well-drained.
Pest Control
To control aphids, apply a neem oil-based insecticide and rinse the plant with a strong spray of water. For spider mites, apply a miticide and keep the humidity around the plant high. To control mealybugs, apply a systemic insecticide and use a cotton swab dipped in alcohol to remove any visible pests.
By following these disease and pest management tips, you can keep your Pausinystalia zenkeri W. Brandt plant healthy and productive, while avoiding common problems that can reduce its growth and reduce its yield of medicinal bark.
