Overall, Claoxylon capense Baill. is a versatile plant with distinct appearance and several traditional and non-traditional uses.Light Requirements
The Claoxylon capense Baill. requires a high amount of sunlight exposure for optimal growth. It needs at least six hours of direct sunlight per day. This plant can thrive in full sunlight or partial shade. In areas with limited sunlight, the plant will stretch towards the light source, resulting in a leggy and weak appearance.
Temperature Requirements
Claoxylon capense Baill. will grow in a wide range of temperature conditions, but the optimal temperature range for growth is between 21°C to 32°C. The plant can tolerate higher temperatures in the range of 35°C to 40°C. In winters, the plant can survive in temperature ranging between 10°C to 16°C. Low temperatures below 10°C can harm the plant resulting in yellowing and dropping of the leaves.
Soil Requirements
The Claoxylon capense Baill. thrives in rich, well-drained, and slightly acidic soil. The pH level of the soil should be between 5.5 to 7. Soil with a pH level above 7 can affect plant growth. This plant prefers soil with high organic matter content and good fertility. Excess water around the roots can rot the plant and damage its growth. So, it is essential to keep the soil moist but not waterlogged. Adding a layer of mulch around the plant can help retain moisture in the soil.
Cultivation of Claoxylon Capense Baill.
Claoxylon capense Baill. is a tropical shrub that is native to Madagascar, Mozambique, and Zimbabwe. It grows well in warm climates with a lot of humidity, and it prefers to be planted in well-draining, sandy soil. When planting Claoxylon capense Baill., make sure to give each plant enough space to grow, as they can reach up to 3 meters in height.
Watering Needs
Claoxylon capense Baill. requires frequent watering to keep the soil moist but not waterlogged. During the growing season, you should water the plant deeply at least once a week. If you notice the leaves drooping or the soil drying out, increase the frequency of watering. However, avoid letting the plant sit in standing water, as this can lead to root rot.
Fertilization
Claoxylon capense Baill. benefits from regular fertilization with a complete, balanced fertilizer. Apply the fertilizer every six to eight weeks during the growing season. Be careful not to over-fertilize, as this can cause the tips of the leaves to burn. Follow the fertilizer's package instructions to determine the correct amount to apply.
Pruning
Pruning Claoxylon capense Baill. is not necessary, but if you want to shape the plant or control its growth, you can prune it lightly in the spring or early summer. Remove any dead, damaged, or diseased branches, and trim back any branches that are growing too long. Avoid pruning in the fall or winter, as this can stimulate new growth that can be damaged by frost.
Propagation of Claoxylon capense Baill.
Claoxylon capense Baill. can be propagated through various methods, such as seed propagation, stem cutting, and aerial layering.
Seed propagation
Seeds can be collected from the mature fruits of Claoxylon capense Baill. The collected seeds must be cleaned and soaked in warm water for a few hours before planting. The seeds can be planted directly in seedling trays filled with fertile soil mix, or they can be sown in containers and transferred to a larger pot once they reach the transplantable stage. The best time for seed germination is in spring, around mid-March.
Stem cutting
Stem cutting is an effective way to propagate Claoxylon capense Baill. Using a sharp pair of pruning shears, take a stem cutting around 10-15cm in length from a healthy and mature plant. Remove the lower leaves and dip the cut end in rooting hormone powder. Plant the cutting in a container filled with well-draining soil mix, making sure to keep it moist until roots develop. Provide protection from direct sunlight until the cutting is established.
Aerial layering
Aerial layering is a method of propagating Claoxylon capense Baill. where a stem or branch is induced to develop roots while still attached to the mother plant. Select a healthy and mature branch, and about 15cm from the tip, cut off a ring of bark around the stem. Apply rooting hormone powder to the exposed portion and wrap moist sphagnum moss around it. Cover the moss with plastic wrap and secure the ends with tape. In a few weeks, roots will develop and can be severed from the mother plant and planted in a pot or directly in the ground.
Disease and Pest Management for Claoxylon capense Baill.
Claoxylon capense Baill., also known as the Forest Poison Bush, is a hardy plant that is generally resistant to pests and diseases. However, with changes in environmental and ecological conditions, the plant can still suffer numerous diseases and pests. Here are some of the common diseases and pests that affect Claoxylon capense Baill. and management solutions that can be applied to control them:
Diseases
Leaf spots and Anthracnose - These are common diseases caused by a fungus. The symptoms of leaf spots are circular necrotic areas that form on the leaves while anthracnose presents itself as small sunken spots with distinct margins that may grow into each other. Both diseases can cause defoliation of the plant. Management: Apply a fungicide that contains copper oxychloride or maneb to control the diseases. Ensure good air circulation and reduce overhead watering to lessen the moisture around the leaves, providing better protection against the spread of the fungus. Remove infected leaves and bury them in deep holes, away from the plant to prevent further spread.
Root rot - This disease is caused by the fungi of the Armillaria group. It causes rots in the plant's root system, which deprives the plant of proper nutrients and ultimately leads to its death. Management: Move the plant to well-draining soil. Avoid over-watering and ensure that the plant's soil is moist but not waterlogged. Apply a fungicide that contains thiophanate-methyl and ensure that the soil is covered with a layer of mulch to prevent moisture loss from the soil.
Pests
Spider mites - These are tiny sap-sucking pests that cause the leaves to develop yellow speckles. Management: Use a miticide that contains abamectin, chlorfenapyr, or spirotetramat. Also, use a strong stream from the hosepipe to wash off the spider mites.
Mealybugs - These pests congregate under the leaves and nodes, causing the plant's growth to stunt, yellow, and ultimately die. Management: Wipe the mealybugs off with a soft cloth or a cotton swab dipped in alcohol. Using horticultural oil or pesticide spray can be an effective measure to control the pests.
Scale insects - They are small and appear as tiny brown-white bumps on the stem or underside of the leaves. They suck the sap from the plant and can cause wilting and yellowing of leaves. Management: You can control the scale insects using pesticides with systemic properties. Alternatively, you can use a cloth soaked in a mixture of alcohol and water to wipe off the scales.
Adopting an integrated pest management (IPM) system can help control both pests and diseases. A healthy plant will withstand and ward off diseases and pests, so ensure that the plant is adequately fertilized, watered, and given the necessary care.
