Pruning off dried, discolored, diseased, and damaged branches enhances the tree's health. The best time to prune this tree is during the winter or spring seasons. Avoid pruning it during the dry period, as this may lead to stunted growth and adversely impact the tree's overall health.
Propagation of Trichilia candollei A.Chev.
Trichilia candollei A.Chev. is a medium-sized tree that is propagated through both sexual and asexual methods. The most common propagation methods for this plant include:
Seed Propagation
Sowing the seeds of Trichilia candollei A.Chev. is the most common propagation method. The seeds can be collected from the mature fruit in the late fall or early winter. The collected seeds should be cleaned and dried to prevent the growth of fungi. Once dried, the seeds can be sown in containers filled with a well-drained soil mix and then covered with a thin layer of sand.
The containers should be kept moist and warm until the seeds germinate, which can take up to two months. Seedlings should be transplanted to larger containers once they have grown two to three true leaves. They can then be propagated to the field once they reach a height of about 30 cm.
Cuttings Propagation
Trichilia candollei A.Chev. can also be propagated through stem cuttings. The best time to take the cutting is during the late winter or early spring when the plant is still dormant. Semi-hardwood cuttings are taken with a length of 20 to 25 cm, with two to three nodes per cutting.
Leaves should be removed from the bottom end of the cutting, and the cuttings then dipped in a rooting hormone. They are then planted in a well-draining soil mix and placed in a well-aerated location with a humidity of around 90 percent.
It takes approximately 45 days for roots to start appearing, and the cuttings can then be transplanted to individual containers before transplanting them to the field.
Disease Management for Trichilia candollei A.Chev.
Trichilia candollei A.Chev. is generally healthy and not prone to many diseases; however, it can still be affected by some diseases. Here are some of the common diseases that might affect the growth and health of the plant:
- Anthracnose: This disease is characterized by dark, sunken spots that appear on the leaves and stems of the plant. It is caused by a fungus that thrives in wet conditions. The best way to manage anthracnose is to avoid overhead watering, remove any affected plant parts and spray the remaining ones with a copper spray.
- Leaf Spot: This disease is caused by a fungus that creates circular spots that appear on the leaves and eventually grow in size. The best way to manage leaf spot is to remove affected plant parts as soon as possible and provide good air circulation.
- Powdery Mildew: Powdery mildew is a fungal disease that causes a powdery substance to appear on the leaves of the plant. The best way to manage this disease is to prune the plant to improve air circulation, remove any affected plant parts, and spray with a fungicide.
Pest Management for Trichilia candollei A.Chev.
Trichilia candollei A.Chev. can be affected by various pests that can damage the plant's growth and overall health. Here are some of the common pests that might affect the plant:
- Aphids: These tiny insects suck the sap from the plant's leaves, causing them to curl and distort. To manage aphids, the plant should be sprayed with insecticidal soap.
- Mealybugs: Mealybugs are soft-bodied insects that resemble cotton balls and usually hide in the crevices of the plant. To manage mealybugs, prune the plant to remove affected plant parts and spray with insecticidal soap.
- Mites: These pests are tiny spider-like creatures that often leave webbing on the plant. To manage mites, spray the plant with a miticide and provide good air circulation.
- Caterpillars: Caterpillars are known for munching on leaves and can cause severe damage to the plant. To manage caterpillars, remove them manually and apply a biological insecticide.
