Common Names
Cleistanthus inundatus J.Léonard var. velutinus J.Léonard is commonly known as "velvet cleistanthus" due to the velvety texture of its leaves. It is also known as "African sandbox tree" and "sandpaper tree" due to its abrasive bark.
Uses
Despite its toxicity, Cleistanthus inundatus J.Léonard var. velutinus J.Léonard has been used in traditional medicine to treat hypertension and diabetes in some parts of Africa. However, its use is not recommended due to its high level of toxicity.
The tree is also used as a source of wood for making small tools and utensils due to its dense and hard wood.
General Appearance
Cleistanthus inundatus J.Léonard var. velutinus J.Léonard is a tree or shrub that can grow up to 10 meters in height. Its leaves are elongated, oval-shaped, and have a velvety texture on the upper surface. The plant has small, greenish-white flowers and a capsule-like fruit that contains the seeds. The bark of the tree is rough, dark brown, and has an abrasive texture.
Overall, the Cleistanthus inundatus J.Léonard var. velutinus J.Léonard is a unique plant species that has both medicinal and practical uses. However, its high level of toxicity means that it should be handled with care and not used for self-medication.
Light Requirements
Cleistanthus inundatus J.Léonard var. velutinus J.Léonard thrives in the bright but indirect sunlight. It is not tolerant of too much direct sunlight, which can lead to its leaf scorching. This plant requires at least 4 hours of sunlight per day, but it can also grow in areas with bright artificial light.
Temperature Requirements
The plant prefers warm and humid environments, with the ideal temperature range being between 18 to 25°C (65 to 77°F). It can also survive in temperatures as low as 10°C (50°F) and as high as 35°C (95°F). However, extreme temperature fluctuations can be damaging to the plant's growth, and it may even lead to leaf drop.
Soil Requirements
Cleistanthus inundatus J.Léonard var. velutinus J.Léonard prefers moist and well-draining soil. It is tolerant of a variety of soil types, including sandy, loamy or clay soils. The pH level of the soil should be within the range of 6.0 to 7.5 for optimum growth. However, the plant is sensitive to waterlogged soils and should not be planted in areas with poor drainage.
Cultivation
When it comes to cultivating the Cleistanthus inundatus J.Léonard var. velutinus J.Léonard, it is important to consider the soil quality. The plant tends to prefer well-drained soil that is rich in organic matter. You should also ensure that the soil has a pH of 6 to 6.5. Plant the Cleistanthus inundatus J.Léonard var. velutinus J.Léonard in a location that receives partial shade to full sun.
Watering Needs
The Cleistanthus inundatus J.Léonard var. velutinus J.Léonard requires regular watering to grow effectively. You should ensure that the soil is moist but not waterlogged at all times. Water the plant deeply once a week, depending on the climate and the humidity levels of the environment. However, avoid overwatering the plant as it can lead to root rot.
Fertilization
Fertilize the Cleistanthus inundatus J.Léonard var. velutinus J.Léonard with a balanced, slow-release fertilizer during the growing season. You should apply the fertilizer twice, first in early spring and again in late summer. Be sure to follow the manufacturer's instructions for dosage and application.
Pruning
Prune the Cleistanthus inundatus J.Léonard var. velutinus J.Léonard in late winter or early spring to maintain its shape and remove any damaged or diseased branches. Cut off any dead or crossing branches, and trim back any overly long branches to prevent the plant from becoming too leggy. Be sure to use clean, sharp gardening shears to avoid injuring the plant.
Propagation of Cleistanthus inundatus J.Léonard var. velutinus J.Léonard
Cleistanthus inundatus J.Léonard var. velutinus J.Léonard is a woody plant that belongs to the Phyllanthaceae family. It is a critical species that grows in the humid forests of Africa. The plant is propagated by seeds or stem cuttings.
Propagation by Seeds
Propagation by seeds is a natural way of reproducing the plant. Cleistanthus inundatus J.Léonard var. velutinus J.Léonard seeds are tiny, round, and black. To propagate the plant by seeds, the seeds must be collected when they are ripe. The seeds should be sown immediately without storing them. Sowing the seeds in a compost mixture with a 1:1 ratio of sand and peat is recommended. The seeds should be sown shallowly and covered with a misting system to ensure the soil is always moist. The optimum temperature required for germination is between 20-28°C. Germination can take up to 90 days, but once germinated, the seedlings are strong and should be transplanted into individual pots.
Propagation by Stem Cuttings
Propagation by stem cuttings is another method used to reproduce Cleistanthus inundatus J.Léonard var. velutinus J.Léonard. Stem cuttings should be taken from the mother plant during the growing season. The cuttings should be about 15-20 cm long, and the bottom leaves should be removed. The cuttings should be planted in a compost mixture with a 1:1 ratio of sand and peat. The plant must be kept moist and humid for proper growth, and hence misting should be done regularly. The optimum temperature required for rooting is between 20-25°C.
Once rooted, the young plants should be gradually acclimatized to normal conditions. Transplanting can be done when the plant is well-established. Cleistanthus inundatus J.Léonard var. velutinus J.Léonard is a slow-growing plant and requires time, effort, and patience to be propagated successfully from stem cuttings.
Disease and Pest Management for Cleistanthus inundatus J.Léonard var. velutinus J.Léonard
Cleistanthus inundatus J.Léonard var. velutinus J.Léonard is a plant that is susceptible to both diseases and pests. For the plant to grow and flourish, it requires proper management and care. Here are some common diseases and pests that might affect the plant, along with suggestions on how to manage them:
Diseases
Bacterial Leaf Spot: Bacterial Leaf Spot is caused by the bacteria Xanthomonas campestris. Symptoms include small, water-soaked spots on the leaves that turn brown and fall off. Management strategies include removing infected leaves, avoiding overhead watering, and applying copper-based fungicides.
Phytophthora Leaf Spot: Phytophthora Leaf Spot is caused by Phytophthora parasitica. Symptoms include brown spots with concentric rings on the leaves. Management strategies include removing infected leaves, improving drainage, and applying fungicides such as Aliette or Subdue.
Canker: Canker is caused by the fungus Periconia pseudoparonychia. Symptoms include sunken spots on the stem, wilting and yellowing leaves. Management strategies include removing infected branches, avoiding over-fertilization and ensuring the plant has good air circulation.
Pests
Aphids: Aphids are small, sap-sucking insects that often gather at the tips of new growth. They can cause leaves to curl and yellow, and stunt the plant's growth. Management strategies include washing the plants with a strong jet of water, applying insecticidal soap, or releasing beneficial insects such as ladybugs.
Spider Mites: Spider Mites are tiny, spider-like pests that feed on the plants' sap. They cause leaves to yellow and become stippled. Management strategies include washing the plant with a strong jet of water, applying insecticidal soap, or introducing predatory mites such as Phytoseiulus persimilis.
Thrips: Thrips are small, slender insects that feed on the plants' leaves and flowers. They cause leaves to become distorted and stippled. Management strategies include removing any weeds or plant debris around the plant, using sticky traps or introducing predatory insects such as lacewings.
By taking a proactive approach to disease and pest management, you can help ensure that Cleistanthus inundatus J.Léonard var. velutinus J.Léonard grows strong and healthy.
