You can prune the plant after the flowering period to promote new growth and control its shape. Always use sharp and clean pruning tools when pruning to avoid damaging the plant.
Propagation of Crotalaria mesopontica Taub. forma glabrescens R.Wilczek
Crotalaria mesopontica Taub. forma glabrescens R.Wilczek can be propagated through both seed and stem cuttings.
Propagation by Seed
The seeds of Crotalaria mesopontica Taub. forma glabrescens R.Wilczek can be germinated directly in the soil or started indoors in nursery trays. If starting indoors, use a well-draining potting mix and keep the soil moist but not waterlogged. Once the seedlings have developed true leaves, they can be transplanted into larger pots or directly into the garden.
Propagation by Stem Cuttings
Crotalaria mesopontica Taub. forma glabrescens R.Wilczek can also be propagated by taking stem cuttings. Choose a healthy, non-flowering stem and cut a 6-inch section using sterilized pruning shears. Remove the leaves from the lower half of the stem and dip the cut end in rooting hormone powder. Plant the cutting in a well-draining soil mix and keep the soil moist but not waterlogged. The cutting should root within 2-4 weeks and can be transplanted into a larger pot or directly into the garden once it has developed a strong root system.
Disease Management
The plant Crotalaria mesopontica Taub. forma glabrescens R.Wilczek is known to be resistant to many diseases. However, some fungal diseases may still affect the plant, especially under certain conditions. The most common fungal diseases that may affect Crotalaria mesopontica include:
- Anthracnose: This fungal disease causes the leaves of the plant to turn yellow and has dark spots. To manage this disease, it is recommended to remove all the infected plant material and treat the remaining parts with a fungicide of copper-based materials.
- Root rot: This is a fungal disease that affects the roots of the plant, causing the plant to wilt and eventually die. To avoid root rot, plant Crotalaria mesopontica in well-drained soil and avoid overwatering.
- Fusarium wilt: This is a soil-borne fungal disease that causes the leaves of the plant to wilt and has yellowing of veins. To manage this disease, it is recommended to remove all the infected plant material and treat the remaining parts with a fungicide of copper-based materials. Additionally, avoid planting the same crop in the infected soil.
Pest Management
Crotalaria mesopontica is usually not affected by pests. However, some insects can cause damage to the plant, especially when the plant is under stress. The most common pests that can attack the plant include:
- Spider mites: They can be identified by the fine webs visible on the leaves. To deal with spider mites, you can hose down the plant with a gentle spray of water, or treat the infested plants with an insecticide containing imidacloprid.
- Aphids: They are characterized by tiny green insects and cause distortion on the leaves of the plant. To control the population of aphids, it is recommended to use an insecticide soap solution or a neem oil spray.
- Caterpillars: They are easily recognized by their soft body and chewing on the foliage of the plant. To prevent the damage caused by caterpillars, it is recommended to use a pesticide that contains Bacillus thuringiensis.
