Overview of Ochna keniensis Sleumer
Ochna keniensis Sleumer, commonly known as the Kenyan plane, is a flowering plant belonging to the Ochnaceae family. It is an endemic plant of Kenya and can be found in the coastal areas of the country.
General Appearance
The Kenyan plane grows as a small tree or shrub, usually not exceeding 3 meters in height. It has shiny, dark green leaves that are arranged opposite each other on the stem. The plant produces yellow flowers that are about 1 cm wide with five petals. The flowers mature into black, shiny fruits that are about 0.5 cm wide.
Common Names
Aside from the Kenyan plane, Ochna keniensis is also commonly known as the African plane, Coast plane or East African plane. This variation in names is often attributed to the geographical region where the plant is found.
Uses of Ochna keniensis
The Kenyan plane has several uses, including traditional medicinal uses. The fresh leaves of the plant are boiled and the resulting solution is used to treat stomach problems. The plant is also used to make strong ropes, thanks to the strength of its wood fibers. The tree is also grown as an ornamental plant, thanks to its beautifully contrasting colors of yellow and black, which are highlighted when the tree is in bloom.
Due to an increase in human activity in the coastal areas of Kenya, the Kenyan plane is currently endangered, with populations decreasing at an alarming rate. Conservation efforts are being made to protect the plant and increase its population.
Light Requirements
Ochna keniensis Sleumer thrives in bright, indirect sunlight but can also tolerate partial shade. It is recommended that the plant receives at least six hours of sunlight per day to promote healthy growth and flowering.
Temperature Requirements
The ideal temperature range for Ochna keniensis Sleumer is between 18 and 25 degrees Celsius. It cannot tolerate frost or extremely low temperatures, which can cause damage to the plant. Thus, growers should ensure that the plant is protected from frost during the winter season.
Soil Requirements
Ochna keniensis Sleumer requires well-draining soil that is rich in organic matter. The soil pH should range between 6.0 and 7.0. The plant can tolerate occasional dry conditions, but consistently wet soil can be harmful and lead to root rot. Growers should ensure that the soil is kept consistently moist but not waterlogged.

- Frequency: Ochna keniensis Sleumer requires minimal pruning. Cut only dead or damaged branches or prune to shape the tree during the early years of growth.
Propagation of Ochna keniensis Sleumer
Ochna keniensis Sleumer is a well-known and widely used landscaping plant in the tropics. It is a native plant to Kenya that can grow up to 7 meters tall and has beautiful yellow flowers that bloom in clusters. Propagation of Ochna keniensis Sleumer is done through various methods:
Seed propagation
Propagation by seed is one of the common methods used to propagate Ochna keniensis Sleumer. The seeds can be collected from the mature fruits and sown directly in the soil or in nurseries. It is essential to remove the fleshy part of the fruit before sowing the seeds. The seeds should be sown at a depth of 1-2 cm and covered lightly with soil. Germination takes place within two weeks to one month.
Cuttings propagation
Cuttings propagation is another method used to propagate Ochna keniensis Sleumer. The plant can be propagated by stem cuttings or branch cuttings. The cuttings should be taken from the current year's growth, and the length of the cutting should be around 10-20 cm. The cutting should be free from diseases and pests and should be treated with rooting hormones before planting. The cuttings should be planted in well-drained soil and kept in a humid environment. They should start producing roots within 2-3 weeks.
Suckers propagation
Suckers propagation is a natural method of propagating Ochna keniensis Sleumer. The plant produces suckers or shoots from its base that can be separated and transplanted to a new location. The suckers should be separated from the mother plant using a sharp knife or pruning shears. The transplanted sucker should be planted in well-drained soil and watered regularly until the plant is established.
Propagation of Ochna keniensis Sleumer is relatively straightforward using the methods mentioned above. With proper care, the plant can be easily propagated and grown in garden landscapes, parks, and public places to enhance their aesthetics.
Disease and Pest Management for Ochna keniensis Sleumer
Ochna keniensis Sleumer, commonly known as the Kenyan Yellow Wood or Mickey Mouse plant, is a small evergreen shrub that is native to eastern Africa. It produces bright yellow flowers and black berries that are edible for humans and birds. Like any plant, Ochna keniensis is susceptible to various pests and diseases that can damage or kill the plant if left untreated. Here are some of the common pests and diseases that can affect Ochna keniensis and ways to manage them:
Pests
One of the most common pests that affect Ochna keniensis is the spider mite. Infestations of spider mites can cause the leaves to turn yellow and drop prematurely, leading to reduced growth and decreased yield. To manage spider mites, you can use insecticidal soap or horticultural oil spray, which can kill mites on contact.
Another pest that can affect Ochna keniensis is the mealybug, which feeds on the sap of the plant and secretes a sticky substance that attracts ants. Mealybug infestations can cause the foliage to turn yellow and become stunted. To manage mealybugs, you can use insecticidal soap or neem oil spray, which can suffocate the pests and prevent them from reproducing.
Diseases
Ochna keniensis is susceptible to various fungal diseases, including powdery mildew and leaf spot. Powdery mildew appears as white or grayish powdery patches on the leaves, stems, and flowers. Leaf spot causes brown or black spots on the leaves, which may spread and cause the leaves to fall off. To manage fungal diseases, you can use a fungicide spray that contains copper or sulfur.
Root rot is another disease that can affect Ochna keniensis, especially if the soil is poorly drained or if the plant is overwatered. Root rot causes the roots to decay, which can lead to wilting, yellowing of leaves, and stunted growth. To manage root rot, you can improve the drainage of the soil and reduce the frequency of watering.
Proper plant care, including regular watering, pruning, and fertilization, can help prevent pest and disease infestations in Ochna keniensis. Additionally, monitoring your plants regularly and identifying and addressing any issues that arise can help prevent problems from spreading and causing irreparable damage to your plants.
