Propagation methods of Cleome angustifolia Forssk. subsp. angustifolia Forssk.
Cleome angustifolia Forssk. subsp. angustifolia Forssk. can be propagated by both seed and stem cutting methods. Let's discuss both methods in detail:
Propagation by Seed:
Propagation by seed is one of the easiest methods for Cleome angustifolia Forssk. subsp. angustifolia Forssk. The ideal time for sowing seeds is late spring, after the danger of frost has passed.
The soil should be well-drained and moist. The seeds should be sown approximately 10 mm deep in a seed tray or directly in the soil. The seedlings should be placed in a light-filled location. Germination can be expected within 5-10 days.
Once the seedlings start developing true leaves, they can be transplanted to their final location. It is essential to keep the soil consistently moist during the germination and transplantation stage.
Propagation by Stem Cutting:
Another propagation method for Cleome angustifolia Forssk. subsp. angustifolia Forssk. is through stem cuttings.
Take healthy cuttings of length 10-15 cm, preferably during the onset of spring. The cuttings should have at least three nodes and should be free from any diseases and pests. Remove the lower leaves and dip the cuttings in rooting hormone powder.
Place the cuttings in a well-draining soil mix and water thoroughly. Cover the cuttings with a transparent plastic bag, which will help maintain high humidity levels. Place the cuttings in a location with indirect sunlight and consistent warmth.
Roots will start growing in about two to three weeks, after which the plastic cover can be removed gradually. Once the plants are established, they should be transplanted to their final location.
Disease Management
Cleome angustifolia Forssk. subsp. angustifolia Forssk. can be susceptible to various diseases, including:
- Bacterial blight: This disease can cause wilting, yellowing, and necrosis of leaves. To manage bacterial blight, it is important to remove and destroy infected plants, avoid overhead irrigation, and maintain good sanitation practices.
- Leaf spot: This disease can cause circular or irregular-shaped spots on the leaves, which can lead to defoliation in severe cases. Fungicides can be used to manage leaf spot, and it is recommended to remove and destroy infected plant debris.
- Powdery mildew: This disease can cause white, powdery spots on the leaves and stems. To manage powdery mildew, it is important to maintain good air circulation, avoid overhead irrigation, and apply fungicides as needed.
Pest Management
Cleome angustifolia Forssk. subsp. angustifolia Forssk. can also be susceptible to various pests, including:
- Aphids: These sap-sucking insects can cause stunted growth, yellowing of leaves, and deformation of flowers. To manage aphids, it is recommended to introduce natural predators such as ladybugs, or use insecticidal soap or oil.
- Spider mites: These tiny pests can cause yellowing, stippling, and webbing on the leaves. To manage spider mites, it is important to maintain good humidity and use insecticidal soap or oil.
- Caterpillars: These larvae can feed on the leaves and stems, causing defoliation. Handpicking and using biological controls such as Bacillus thuringiensis can manage caterpillar infestations.
