Cassia aubrevillei Pellegr., commonly known as Aubreville's cassia, is a shrub or small tree that belongs to the family Fabaceae. The plant is native to Cameroon and is known for its ornamental value and medicinal properties.
Propagation methods
Cassia aubrevillei Pellegr. can be propagated through various methods such as seeds and cuttings.
Propagation through seeds
The seeds of Cassia aubrevillei Pellegr. are easy to collect and germinate. The seeds should be collected from the parent tree when they are fully matured and brownish in color. The seeds should then be soaked in warm water for 24 hours to soften the seed coat. The seeds can be sown in a potting mix consisting of equal parts of sand and loam. The potting mix should be kept moist and the seeds should germinate within a few weeks. The seedlings should be transplanted into individual pots when they are about 4-6 inches tall.
Propagation through cuttings
Cassia aubrevillei Pellegr. can also be propagated through stem cuttings. The cuttings should be taken from the parent tree during the dormant season. The cuttings should be about 6 inches long and should have at least 2-3 nodes. The lower leaves should be removed and a rooting hormone should be applied to the cut end. The cuttings should be planted in a potting mix consisting of equal parts of sand and peat moss. The potting mix should be kept moist and the cuttings should develop roots within a few weeks. The rooted cuttings should be transplanted into individual pots.
Cassia Aubrevillei Pellegr.: Disease Management
Cassia aubrevillei Pellegr. is a hardy plant species, but it is still susceptible to certain diseases that can limit growth and yield. Below are some common diseases affecting the plant and ways to manage them.
Fungal Leaf Spots
Fungal leaf spots are the most common disease that affect Cassia aubrevillei Pellegr. The fungal pathogens responsible for the disease are usually from the genus Cercospora, Phaeosphaeria, or Alternaria. To manage this disease, remove and destroy any infected leaves to prevent the spread of the spores. Also, avoid overhead irrigation and crowded plantings to reduce humidity around the plant. Applying a fungicide containing copper or mancozeb might provide additional protection against the disease.
Powdery Mildew
Powdery mildew is another fungal disease that affects Cassia aubrevillei Pellegr. The disease usually appears as white powdery spots on the leaves. To manage the disease, you can spray the affected plants with a homemade solution of baking soda, water and oil (such as olive oil or sunflower oil). Another option is to apply a fungicide containing potassium bicarbonate, neem oil, or sulfur.
Cassia Aubrevillei Pellegr.: Pest Management
Cassia aubrevillei Pellegr. is also prone to attack by various pests. Below are some of the common pests affecting the plant and ways to manage them.
Scales
Scales are small insects that attach themselves to the leaves of Cassia aubrevillei Pellegr. and suck the sap from the plant, leading to yellowing and stunted growth. You can manage the pest by rubbing Alcohol or soapy water on the affected parts to kill them. Alternatively, insecticides containing neem oil, pyrethrins, or horticultural oils can be used to control scales.
Caterpillars
Caterpillars are another pest that can damage the plant by chewing the leaves and stems of Cassia aubrevillei Pellegr. To manage caterpillars, you can remove and destroy any affected tissues or spray the plant with an insecticide containing Bacillus thuringiensis (Bt).
Implementing good cultural practices such as cleanliness, proper sanitation, and adequate nutrition can help prevent attack by both diseases and pests. Regular inspection of the plant is essential to identify any symptoms of a possible infestation so that prompt action can be taken to manage the problem.
