Light Requirements
Crotalaria tigrensis Baker is a plant that requires full sunlight to thrive. It needs at least 6 hours of direct sunlight exposure each day. Inadequate sunlight exposure can weaken the plant and lead to stunted growth or fruiting. Therefore, it is recommended to plant this species in open areas or near windows that have a southern exposure.
Temperature Requirements
The optimum temperature range for Crotalaria tigrensis Baker growth is 20°C-30°C. This plant is sensitive to low temperatures and cannot withstand frost. Temperatures below 10°C may cause leaves to wilt and eventually fall off. Therefore, it is not suitable to plant Crotalaria tigrensis Baker in areas with low temperatures. However, it can withstand high temperatures but may require additional irrigation.
Soil Requirements
Crotalaria tigrensis Baker requires well-draining soils. The plant cannot tolerate waterlogged soils which can cause root rot. Sandy soils are preferred because they provide both drainage and enough soil nutrients. Furthermore, the soil pH should range between 6.0-7.8. The plant is also tolerant to saline soils. Therefore, it is adaptable to some coastal soils. Prior to planting, it is recommended to ensure that the soil is rich in organic matter. It is also advised to add additional fertilizer to the soil to improve the growth of Crotalaria tigrensis Baker.
Cultivation
Crotalaria tigrensis Baker is a hardy plant that grows well in full sun or partial shade. It is well-adapted to dry and arid conditions and can tolerate a wide range of soil types, from clay to sandy soils. The plant can grow up to 1.5 meters in height and should be spaced about 60 cm apart when planting.
Watering needs
Crotalaria tigrensis Baker requires moderate watering when grown in well-drained soils. The plant should be watered deeply and regularly during the growing season, especially during periods of drought. Overwatering can lead to root rot and other diseases, so it is essential to avoid watering the plant too much.
Fertilization
The plant does not require much fertilization and can grow well in poor soil conditions. However, adding organic matter to the soil can help improve plant growth and health. You can fertilize the plant with a balanced NPK fertilizer every two months, starting from the beginning of the growing season.
Pruning
Crotalaria tigrensis Baker does not require much pruning, and pruning should be limited to removing any dead or damaged stems. However, excessive growth may require pruning to maintain the desired shape and prevent the plant from sprawling. Pruning should be done during the plant's dormant season or just after flowering.
Propagation of Crotalaria tigrensis Baker
Crotalaria tigrensis Baker can be propagated through various methods such as:
Seed Propagation
Seeds of Crotalaria tigrensis Baker can be used for propagation. The seeds should be harvested when they are mature, dried, and stored under cool and dry conditions. They can be sown directly in the field or in seedbeds covered with a thin layer of soil. Germination occurs within 6-12 days and the seedlings can be transplanted when they are about 4-6 weeks old.
Cuttings Propagation
Cuttings are another method of propagation for Crotalaria tigrensis Baker. Softwood cuttings are taken in the growing season and treated with rooting hormones. The cuttings are then planted in well-drained soil and kept moist until they take root.
Division Propagation
Division is a propagation method that involves dividing a mature plant into smaller parts. Crotalaria tigrensis Baker can be divided in spring or early autumn. The plant is lifted carefully, and using a sharp knife, it is divided into smaller parts, making sure each part has roots and shoots. The divided plants can then be replanted in a suitable location.
Layering Propagation
Layering is another propagation method that involves pegging a stem to the ground and allowing it to form roots before it is separated from the parent plant. Crotalaria tigrensis Baker can be propagated by layering in spring or early summer. A portion of the stem is buried in the soil and kept moist until roots develop. The new plant can then be separated from the parent plant and transplanted.
Disease and Pest Management for Crotalaria tigrensis Baker Plant
Crotalaria tigrensis Baker is a beautiful and unique plant valued for its hardiness and attractive yellow flowers. However, like all plants, it is susceptible to certain pests and diseases. As a plant owner, it is important to be aware of these problems and take necessary measures to protect the plant from damage.
Common Diseases
Crotalaria tigrensis Baker is susceptible to a number of diseases, including:
- Leaf Spot: This is a fungal disease that affects the leaves of the plant. The leaves develop small, circular spots that are yellow or brown in color, with a red or purple border.
- Root Rot: This is a fungal disease that affects the roots of the plant. The roots become dark and mushy, making it difficult for the plant to absorb water and nutrients.
- Powdery Mildew: This is a fungal disease that affects the leaves of the plant. The leaves develop a white, powdery coating that can spread quickly and damage the plant.
Effective Disease Management Techniques
Here are some methods that can be used to manage diseases that affect Crotalaria tigrensis Baker:
- Remove infected plant parts: If any part of the plant is infected, it should be removed immediately to prevent the disease from spreading.
- Keep plant dry: Watering the plant at the right time and in the right way can help prevent fungal diseases. Avoid watering the leaves and instead water the plant at the base.
- Use fungicides: Applying fungicides can also help manage fungal diseases. Reduce the frequency of application at the end of the growing season to avoid injury to the environment.
Common Pests
Crotalaria tigrensis Baker is also vulnerable to some insect pests which include:
- Aphids: These small, pear-shaped insects suck sap from the plant causing the leaves to turn yellow and wilt.
- Caterpillars: These are the larvae of certain species of moths and butterflies that eat plant leaves and stems.
- Spider Mites: These tiny arachnids feed on the undersides of leaves, causing a stippled appearance. They prefer hot, dry conditions and are largely resistant to insecticides.
Effective Pest Management Techniques
To manage pest infestation on Crotalaria tigrensis Baker, consider the following techniques:
- Handpicking: The best way to get rid of small infestations is to manually remove the pests from the plant.
- Natural predators: Encourage natural predators of the pests, for example, ladybugs feed on aphids. Plant wildflowers around the plant to attract beneficial insects and reduce the number of pests.
- Use insecticides: If the infestation is severe, use pesticides, and herbicides which contain pyrethrin or sulfur for best results.
By employing these techniques, the Crotalaria tigrensis Baker plant owner can keep the plant healthy and attractive, and prevent damage from common pests and diseases.
