Appearance of Combretum dilembense De Wild.
Combretum dilembense De Wild. is a deciduous tree that can grow up to 20 meters in height. Its leaves are simple, alternate, and oblong-shaped. The plant's flowers are small and creamy-white, arranged in dense clusters. The fruit of this tree is a dry, woody capsule containing one seed. The bark of Combretum dilembense De Wild. is light brown, rough, and deeply furrowed.
Light Requirements
Combretum dilembense De Wild. requires full sun to grow optimally. It needs at least 6 hours of direct sunlight per day to thrive. Lack of sufficient sunlight can reduce its growth and overall health.
Temperature Requirements
Combretum dilembense De Wild. grows well in warm temperatures ranging from 20°C to 35°C. It can tolerate high temperatures up to 40°C but cannot withstand frost or extreme cold conditions. The plant can grow in both humid and arid conditions.
Soil Requirements
The plant prefers well-drained soils with medium texture. Combretum dilembense De Wild. can tolerate a wide range of soil pH ranging from slightly acidic to slightly alkaline (6.0-8.0). It grows well in soils rich in organic matter. However, the plant is not tolerant of waterlogged or compacted soils.
Cultivation methods
The Combretum dilembense De Wild. plant can be grown in most types of soils, preferring well-drained and fertile soils. The plant thrives in full sun and can tolerate semi-shade. Cuttings can be used, and rooted cuttings can be transplanted to larger containers or directly to the field. The optimal planting distance is 4 m from plant to plant, and 8 m between the rows. Planting can be done during the rainy season since high humidity and soil moisture levels favor the establishment of the plant.
Watering needs
The Combretum dilembense De Wild. plant requires moderate watering. The plant should be irrigated in areas with insufficient rainfall. Watering should be done once or twice a week, depending on the soil type and climatic conditions. Overwatering can lead to root rot, which can be fatal to the plant.
Fertilization
Applying compost or manure to the soil before planting is recommended to improve the soil's fertility. Additionally, applying a balanced chemical fertilizer can help improve the plant's growth and development. The recommended fertilizer application rate is 150 g per plant per year. Fertilizer application should be done before the rainy season and during plant growth periods.
Pruning
Pruning should be done to remove broken or damaged branches, weak or diseased twigs, and promote plant growth. The optimal time to prune the Combretum dilembense De Wild. plant is after the flowering period. Pruning should be done during the dry season when the plant is dormant. This helps reduce water stress and minimize the risk of disease. Light pruning is recommended to maintain the plant's shape, and pruning cuts should be made just above a bud or branch junction.
Propagation of Combretum Dilembense De Wild.
Propagation of Combretum dilembense De Wild. mainly involves two methods: seed propagation and stem cuttings.
Seed propagation
Seeds of Combretum dilembense De Wild. can be collected from mature fruits during the dry season. The collected seeds should be soaked in water for 12 hours to enhance germination before sowing. The seeds can be sown directly in the nursery beds or in containers filled with a mixture of soil and organic matter.
The nursery bed or container should be kept moist by regular watering. Germination occurs within 1-2 weeks, after which the seedlings can be transplanted into individual containers or pots. The seedlings can be planted directly into the field or transplanted to another location during the rainy season.
Stem cuttings
Propagation of Combretum dilembense De Wild. can also be done through stem cuttings. Softwood stem cuttings about 15-20cm in length can be collected from mature plants during the rainy season.
The leaves on the lower part of the stem should be removed, and the cutting dipped in rooting hormone before being planted in a rooting medium. The rooting medium should consist of sand and organic matter in equal proportions.
The cuttings should be kept moist and placed in a shaded area to avoid direct sunlight. Roots will start to form within 2-3 weeks, after which the cuttings can be transplanted into individual containers or pots. After 4-6 weeks, the rooted cuttings can be planted directly into the field or transplanted to another location during the rainy season.
Disease and Pest Management of Combretum dilembense De Wild.
Combretum dilembense De Wild. is a hardy plant resistant to most pests and diseases. However, proper care and management are still necessary to prevent the infestation of pests and spread of diseases, which might affect its growth and yield.
Common Diseases
Some of the common diseases that might affect Combretum dilembense De Wild. include:
- Cankers: These are sunken areas on the plant's stems or branches caused by bacteria or fungi. They cause the plant to wilt, wither, and eventually die. To manage cankers, prune the affected areas and destroy them. Also, ensure proper sanitation and avoid physical damage to the plant.
- Powdery mildew: This is a fungal disease that causes a white or gray powdery coating on the leaves, stems, and flowers of the plant. It affects the plant's growth and yield, reducing its quality. To manage powdery mildew, prune the affected areas, increase air circulation, and avoid overhead watering.
- Root rot: This is a fungal disease that affects the plant's roots, causing them to decay and rot. It causes wilting and yellowing of leaves, and ultimately death. To manage root rot, ensure proper drainage, avoid over-watering, and use fungicides if necessary.
Common Pests
Some of the common pests that might affect Combretum dilembense De Wild. include:
- Aphids: These are small, soft-bodied insects that suck sap from the plant's leaves, causing them to curl and eventually fall off. They also transmit plant viruses. To manage aphids, prune the affected areas, spray with strong jets of water, and use insecticides if necessary.
- Spider mites: These are tiny pests that feed on the plant's sap, causing yellowing, and bronzing of leaves. They spin webs on the leaves, which can affect the plant's photosynthesis. To manage spider mites, prune the affected areas, increase air circulation, and use insecticides if necessary.
- Thrips: These are small, slender insects that feed on the plant's leaves, causing discoloration and deformation. They also transmit plant viruses. To manage thrips, prune the affected areas, use yellow or blue sticky traps, and use insecticides if necessary.
Effective management of pests and diseases is critical to the growth and yield of Combretum dilembense De Wild. As such, it is essential to monitor the plant regularly, identify any signs of infestation, and apply appropriate management measures promptly.
