The leaves are compound, with 4-5 leaflets measuring between 5 to 25 centimeters in length. The flowers of this plant are bright yellow in color, and can be seen blooming between the months of February and June.
Uses
Traditionally, different parts of the Trichilia integrifilamenta tree have been used medicinally to treat a variety of ailments such as fever, colds, and high blood pressure. The bark has also been used as a tonic for the digestive system and as a remedy for skin irritations. In addition, the wood of the tree has been used for carving and construction purposes.
Today, the Trichilia integrifilamenta tree is also valued for its ornamental purposes due to its beautiful flowers and foliage. It can be found in gardens and along roadsides, adding a burst of color to the landscape.
Light Requirements
Trichilia integrifilamenta C.DC. requires full to partial sunlight to grow properly. It is a fairly adaptable plant and can tolerate varying levels of light exposure. However, prolonged exposure to direct sunlight in hot and dry conditions can be damaging to the plant.
Temperature Requirements
The ideal temperature range for the growth of Trichilia integrifilamenta C.DC. is between 20°C to 35°C. The plant can tolerate temperatures as low as 10°C but cannot survive extreme cold conditions. In hot and dry climates, Trichilia integrifilamenta C.DC. may require extra watering to maintain its moisture levels.
Soil Requirements
Trichilia integrifilamenta C.DC. grows best in well-draining soil that is rich in organic matter and slightly acidic to neutral pH (5.5 to 7.0). The soil should be a mix of sand, loam, and clay to provide the necessary nutrients and moisture. The plant prefers soil that is consistently moist but not waterlogged.
Cultivation of Trichilia Integrifilamenta C.DC.
Trichilia Integrifilamenta C.DC. is a tropical tree that thrives in humid and hot conditions. It is best grown in areas with a temperature range of 25-30°C and adequate sunlight exposure. The plant grows well in well-draining and fertile soils.
Watering Needs
The plant requires regular watering, particularly when it is young and still establishing its roots. Watering should be done deeply but infrequently to prevent over-watering, which can lead to root rot. In the dry season, the plant should be watered at least twice a week.
Fertilization
To promote healthy growth and development, the Trichilia Integrifilamenta C.DC. requires proper fertilization. It is recommendable to use organic fertilizers rich in nitrogen, phosphorus, and potassium. Fertilizers can be applied during the rainy season to support the tree's growth and replenish soil nutrients.
Pruning
Pruning is essential to control the size and shape of the plant, remove dead or diseased branches and encourage new growth. It is advisable to prune the tree during the dormant season to promote the growth of new shoots and minimize stress on the tree. Young trees require training and shaping during the first few years to establish a strong framework.
Propagation of Trichilia integrifilamenta C.DC.
Trichilia integrifilamenta C.DC. can be propagated by seed and vegetative methods such as stem cuttings and air layering.
Seed propagation
Seeds of Trichilia integrifilamenta C.DC. should be collected from ripe fruit and then washed and dried in the sun. The seeds should be sown immediately because they lose their viability quickly. The seeds should be sown in a well-draining potting mix and kept moist. Germination occurs within 2-3 weeks, and the seedlings should be transplanted to individual pots when they are 2-3 inches tall.
Stem cutting propagation
Stem cuttings of Trichilia integrifilamenta C.DC. should be taken from healthy, mature plants during the growing season. The cuttings should be approximately 8-10 inches long and taken from the upper part of the plant. The lower leaves should be removed, and the cutting should be dipped in rooting hormone and planted in a well-draining potting mix. The cutting should be kept moist and should develop roots within 2-3 weeks. After the roots have developed, the cutting should be transplanted to individual pots.
Air layering propagation
Air layering is a vegetative propagation method that involves inducing roots to develop on a stem that is still attached to the parent plant. To propagate Trichilia integrifilamenta C.DC. using air layering, a section of the stem should be identified, and a ring of bark should be removed from the stem using a sharp knife. The exposed area should be treated with rooting hormone and wrapped in moist sphagnum moss. The moss should be covered with plastic wrap and tied with string to keep it moist. After 2-3 months, roots should develop from the exposed area. The rooted section of the stem can be cut off and planted in a well-draining potting mix.
Disease Management
The plant Trichilia integrifilamenta C.DC. is susceptible to various fungal infections, including anthracnose, leaf spot, and powdery mildew. These diseases can cause significant damage to the plant and reduce yield if left untreated. The following are ways to manage these diseases:
- Prune infected and dead branches to reduce the spread of disease.
- Provide good air circulation around the plant to inhibit fungal growth.
- Practice crop rotation to reduce the buildup of fungal spores in the soil.
- Use fungicides to control the spread of fungal infections.
Pest Management
The plant Trichilia integrifilamenta C.DC. is also prone to attack by various insects, including scales, caterpillars, and mealybugs. These pests can cause significant damage to the plant by feeding on the leaves, stems, and fruits. The following are ways to manage these pests:
- Remove infected plant parts and destroy them to reduce the pest population.
- Use insecticides to control the spread of pests.
- Introduce natural predators such as beneficial insects and birds to control pests.
- Apply a layer of organic mulch around the plants to discourage pest infestation.
