To enable the plant to thrive and produce the desired stimulant, certain growth conditions must be met. Below are some of the essential growth conditions that must be provided:
Light
Tricalysia Dundusanensis De Wild thrives best in well-lit areas. As such, it requires a lot of sunlight to grow properly. It's recommended to place the plant in areas where it can receive a minimum of six hours of direct sunlight per day. If grown indoors, it must be placed in a room with large windows or under artificial lights that mimic natural light.
Temperature
The ideal temperatures for Tricalysia Dundusanensis De Wild growth are between 20°C to 30°C. The plant can tolerate temperature variations between 5°C to 35°C, but this must be gradual. Extreme temperature changes can affect its growth and reduce flower bud formations. It's essential to monitor the temperature conditions and provide adequate ventilation to prevent humidity build-up that can lead to disease infestation.
Soil Requirements
The soil requirements for Tricalysia Dundusanensis De Wild are specific. The plant thrives best in well-draining soils that are rich in organic matter. The soil must be moist but not waterlogged. Saturated soils can reduce the availability of oxygen to the roots and lead to root rot. The soil pH must be between 4.5 and 6.0 for optimal growth. It's important to conduct soil tests to determine the soil pH before planting.
Cultivation of Tricalysia Dundusanensis De Wild.
Tricalysia Dundusanensis De Wild. is an evergreen flowering plant that belongs to the Coffee family. It is commonly found in tropical regions of Africa, particularly in the Congo Basin. To cultivate this plant, you should consider the following:
- Tricalysia Dundusanensis De Wild. thrives in fertile, well-draining soils that are rich in organic matter. You should plant it in moist soils with good drainage to prevent waterlogging.
- It grows well in both direct and indirect sunlight. Therefore, you should plant it in an area that receives at least 6 hours of sunlight daily.
- The best temperature for Tricalysia Dundusanensis De Wild. growth ranges between 22 to 28 degrees Celsius, but it can still grow in temperatures of up to 30 degrees Celsius.
- This plant can also grow in humid conditions; therefore, you should ensure that the humidity levels stay between 60-70%.
Watering Requirements
Tricalysia Dundusanensis De Wild. requires regular watering to keep the soil moist but not waterlogged. You can water it deeply whenever the topsoil appears dry, and it is advisable to use lukewarm water to avoid shock to the roots. During the dry season, you may need to water the plant more frequently to keep the soil moist.
Fertilization
Tricalysia Dundusanensis De Wild. requires adequate and balanced fertilization for optimum growth. You can use a complete organic fertilizer that is high in nitrogen for the plant to grow healthy foliage, phosphorus for root growth, and potassium for flower and fruit development. Apply the fertilizer during the growing season, usually during spring or summer, and ensure that you follow the manufacturer's instructions for quantities and application duration.
Pruning
Pruning is an essential aspect of Tricalysia Dundusanensis De Wild. care. You should trim the plant regularly to encourage growth and maintain its shape.

Propagation of Tricalysia dundusanensis De Wild.
Tricalysia dundusanensis De Wild., commonly known as Dundusi's Tricalysia, can be propagated by seeds and vegetative cuttings.
Seed propagation
The seeds of Tricalysia dundusanensis De Wild. are small, brown, and shiny. They should be sown in well-draining soil in a nursery bed or a pot. The soil should be kept moist, but not waterlogged. Germination typically takes two to three weeks.
After germination, the seedlings should be thinned out to prevent overcrowding. The young plants should be kept in a shaded area for at least six months and should be provided with regular watering and fertilization.
Vegetative propagation
Tricalysia dundusanensis De Wild. can also be propagated vegetatively using stem cuttings. Select healthy stems from mature plants and make clean cuts using a sharp knife. Cuttings should be about 10-15 cm long and should have 2-3 nodes. Remove the leaves from the lower half of the cutting and dip the cut end in rooting hormone powder to promote root growth.
The cuttings should be inserted about 2-3 cm deep in a well-draining rooting medium. The medium should be kept moist and the cuttings should be placed in a shaded area. Roots will typically form in 4-6 weeks, at which point the newly rooted plants can be transplanted into larger containers or in the field.
