Light Requirements
Dichapetalum angolense Chodat var. glabriusculum Hauman requires full sun to partial shade for optimal growth. The plant should receive at least 6 hours of direct sunlight every day. However, it can also thrive in partially shaded areas, provided it receives enough natural light.
Temperature Requirements
The plant enjoys warm temperatures and is best suited to the tropical and subtropical regions. The ideal temperature range for Dichapetalum angolense Chodat var. glabriusculum Hauman is between 18°C and 35°C (64°F and 95°F). Temperatures below 15°C (59°F) can harm the plant.
Soil Requirements
The plant requires well-drained and fertile soil for optimal growth. The soil should be slightly acidic to neutral, with a pH range of 6.0 to 7.5. Sandy loam soil with good water-holding capacity is ideal for the plant. It is important to ensure good drainage, as the plant cannot tolerate waterlogged soils.
Cultivation Methods
Dichapetalum angolense Chodat var. glabriusculum Hauman is a tropical plant that requires a warm and humid environment to grow. It should be planted in well-draining soil with a slightly acidic to neutral pH level. The plant thrives in partial to full shade and should be protected from direct sunlight, especially during the hottest parts of the day.
If growing this plant as a houseplant, ensure that it is not placed too close to an air conditioning or heating vent, as this can cause the plant to dry out quickly.
Watering Needs
This plant requires regular watering but should not be watered excessively, as this can lead to root rot. Water the plant when the top inch of soil is dry to the touch, and ensure that excess water can drain out of the pot or planting area. Avoid getting water on the leaves, as this can encourage the growth of fungal diseases.
Fertilization
Dichapetalum angolense Chodat var. glabriusculum Hauman benefits from regular fertilization, especially during the growing season. Fertilize the plant every two weeks with a balanced fertilizer, diluted to half strength. Be sure not to over-fertilize, as this can harm the plant.
Pruning
Pruning is not necessary for Dichapetalum angolense Chodat var. glabriusculum Hauman, but you may want to trim the plant to control its size and shape. Only prune in the spring or summer, and avoid cutting back too much of the plant at once, as this can cause stress and may harm the plant.
Propagation of Dichapetalum angolense Chodat var. glabriusculum Hauman
Dichapetalum angolense Chodat var. glabriusculum Hauman, also known as the "Mouse Button" plant, is a rare and endangered flowering plant native to Angola. Its propagation is vital to conserving the species, and it can be done through:
Seeds
The most common propagation method for Dichapetalum angolense Chodat var. glabriusculum Hauman is through seeds. The seeds of the plant are small, black, and somewhat flattened. They can be collected from the plant and sown immediately. The seeds should be soaked in water for a few hours before planting to soften the hard seed coat. After soaking, plant the seeds in a well-draining soil mixture and keep the soil evenly moist until germination. The seedlings can be transplanted to a larger container or directly to the ground once they have grown a few leaves.
Cuttings
Propagation of the Dichapetalum angolense Chodat var. glabriusculum Hauman can be done through stem cuttings. Take cuttings from the plant's stem in early spring or summer. Select a healthy, disease-free stem, and cut it with a sharp, sterile knife just below a node. Remove any leaves from the bottom half of the cutting and dip the cut end in rooting hormone powder. Plant the cutting in a well-draining soil mix and keep it moist. Place the pot in a warm, bright area, but not in direct sunlight. Transplant the cutting to a larger container or directly to the ground once it has rooted and started to grow new leaves.
