Common Names
Dorstenia subtriangularis Engl. is also known by a number of common names, such as the Triangle-leaved Dorstenia, Dorstenia, and the Ethiopian Dorstenia. These names are often used interchangeably based on the region where the plant is found.
General Appearance
The Dorstenia subtriangularis Engl. is a succulent plant that can grow up to 80 cm in height and 30 cm in diameter. Its leaves are triangular in shape and up to 25 cm long and 10 cm wide. Its stem is covered with small fine hairs, and its flowers are inconspicuous and yellow in color.
This plant also produces small, spherical fruits that are around 4 mm in diameter. It has been reported that the seeds require a special condition to be germinated, as the fruit must be eaten by a particular ant species that will destroy the fruit and distribute the seeds, facilitating germination.
Uses
The Dorstenia subtriangularis Engl. is widely used in traditional medicine in various African countries. The roots and stem of this plant are used to treat a wide range of ailments, such as fever, malaria, respiratory infections, and stomach problems.
Furthermore, the plant's fibrous stem makes it useful in producing sustainable materials, such as ropes and baskets.
In addition, the Dorstenia subtriangularis Engl. also adds aesthetic value to home gardens and landscapes, as its distinct shape and size make it a unique addition.
Overall, the Dorstenia subtriangularis Engl. is a fascinating and useful plant species that continues to play an important role in African traditional medicine and sustainable materials production.
Light Requirements
The Dorstenia subtriangularis Engl. plant grows best in areas with bright, indirect sunlight. Direct sunlight can be too intense and cause the plant's leaves to burn. It is recommended to place the plant near a north-facing window or east-facing window where it can receive adequate light without direct exposure to the sun.
Temperature Requirements
This plant thrives in temperatures that range from 60-75°F (15-24°C). Temperatures below 50°F (10°C) can damage the plant or even kill it. To maintain a suitable temperature, it is best to keep the plant indoors in a room with controlled temperature settings. Avoid placing the plant near air conditioning units or heating vents as this can affect the temperature around the plant.
Soil Requirements
Proper soil is essential in cultivating a healthy Dorstenia subtriangularis Engl. plant. This plant requires well-draining soil with a pH of 6.1-6.5. A soil mixture of peat, perlite, and sand is ideal. A well-draining pot with drainage holes at the bottom is also necessary to prevent water from accumulating at the roots of the plant.
Cultivation Methods for Dorstenia subtriangularis Engl.
The Dorstenia subtriangularis Engl. plant can be cultivated through propagation using its rhizome. Potting soil mixed with perlite or sand can be used, and the seeding should be shallowly planted at about 2-3 cm.
The plant is susceptible to rotting, and it prefers to be grown in a well-draining medium, and temperatures above 20°C. It also requires bright but indirect lighting, not under direct sunlight.
Watering Needs for Dorstenia subtriangularis Engl.
The plant prefers to be watered when the soil appears slightly dry to prevent overwatering, which can lead to root rot. Regular watering can be reduced to once a month during winter.
Watering using a well-draining container will minimize chances of water logging, and a drip tray should be used to catch excess water.
Fertilization for Dorstenia subtriangularis Engl.
The Dorstenia subtriangularis Engl. plant can benefit from regular fertilization with a balanced solution, preferably a slow-release fertilizer and applied only during the growing seasons of spring and summer, avoiding application in the dormant winter season.
The recommended fertilizer strength is usually 1/4 strength mixed with water.
Pruning of Dorstenia subtriangularis Engl.
Pruning should be done to remove dry or withered leaves and stems which can help to encourage new growth and enhance the plant's shape, but only a few Dorstenia subtriangularis leaves should be removed at once as the plant depends on them to make its food through photosynthesis.
The removed plant parts should be sterilized to avoid the spread of any diseases. A clean and sharp pair of shears or scissors should be used.
Propagation of Dorstenia subtriangularis Engl.
Dorstenia subtriangularis Engl., also known as the "African bonsai," is a unique and intriguing succulent that is generally propagated asexually. There are several propagation methods to propagate Dorstenia subtriangularis, which include:
Seed Propagation
Dorstenia subtriangularis can be propagated using seeds, but this method is often challenging due to the plant's unique growth cycle. The seeds must be sown in a well-draining soil mix, and stratification is often required to break dormancy. The soil should be kept consistently moist, and the temperature should be around 70-75 degrees Fahrenheit. Germination can be slow, and seedlings may take several years to reach maturity.
Division
Another propagation method for Dorstenia subtriangularis is division. Mature plants can be carefully divided to create new plants. The plant should be carefully removed from its pot, and the rhizomes should be gently separated. Each division should have at least one healthy stem and several leaves. The divisions should be replanted into well-draining soil and kept in a warm, bright location.
Leaf Cuttings
Leaf cuttings can also be used to propagate Dorstenia subtriangularis. The leaves should be removed carefully from the stem, and any flesh should be trimmed away. The cutting should be allowed to dry for several hours before being planted in well-draining soil. The cutting should be kept in a warm, shaded location, and soil should be kept lightly moist until new growth emerges.
Propagation of Dorstenia subtriangularis can be challenging, and it may take several attempts to achieve successful propagation. However, with proper care, the plant can be propagated and enjoyed for years to come.
Disease and Pest Management for Dorstenia Subtriangularis Engl.
Although Dorstenia subtriangularis Engl. is a hardy plant, it is susceptible to some diseases and pests. Here is some information on common diseases and pests and how to manage them:
Diseases
Dorstenia subtriangularis Engl. can be vulnerable to root rot and leaf spot diseases. Root rot is caused by overwatering or poorly-draining soils, while leaf spot diseases are usually caused by fungal infections. To prevent root rot, ensure that the soil is well-draining by using a pot with drainage holes and reducing watering to avoid waterlogging. To prevent fungal infections, ensure the plant is in well-ventilated spaces and water around the roots rather than the leaves.
Pests
Dorstenia subtriangularis Engl. can also be prone to pest infestations. Common pests include spider mites and mealybugs. Spider mites are tiny pests that can damage leaves and are often found on the undersides of leaves. Mealybugs are white bugs that form cottony masses on the plant's leaves and stems. To get rid of spider mites, wipe down the leaves with a damp cloth or spray the plant with insecticidal soap. To eliminate mealybugs, remove the affected parts of the plant and apply insecticidal soap.
It is essential to prevent the spread of pests and diseases and ensure the plant is healthy. Regularly inspect the plant, remove dead or diseased leaves, and avoid overcrowding that can lead to fungal infections.
