The plant can be propagated using seeds or vegetative methods such as division and cutting. Cuttings taken from healthy plants should be planted in a mixture of soil and sand and kept moist (but not waterlogged) until roots develop.
Watering Needs
The Pulicaria leucophylla Baker requires moderate watering during the summer season and minimal watering during the winter. It is advisable to avoid overwatering the plant to prevent root rot. The plant can thrive in a range of humidity levels, but it is crucial to ensure the soil is well-drained to minimize the risk of infection.

Cuttings
Propagating Pulicaria leucophylla through cuttings is another method. The best time to take cuttings is in the spring when the plant is actively growing. Take a healthy stem cutting that is about 4-6 inches long and remove the bottom leaves. Dip the cut end in rooting hormone and plant it in a well-draining potting mix. Keep the soil moist and place the pot in bright, indirect sunlight. Once roots have formed, transplant the cutting into a larger container or in the ground.
Division
Propagation through division is best done in the spring. Dig up the plant and carefully separate the root system into smaller sections. Each section should have at least one stem and a healthy root system. Plant the sections into a well-draining soil mix and water them thoroughly.
Overall, Pulicaria leucophylla can be easily propagated through various methods. Ensure that the soil is well-draining and moist for success in any propagation method.
Disease and Pest Management for Pulicaria leucophylla Baker
Pulicaria leucophylla Baker is a plant native to Africa and can be grown in a range of temperate climates. However, like all plants, it is susceptible to certain diseases and pests that can reduce its health and vigor. Here are some common diseases and pests that might affect this plant and suggestions on how to manage them:
Diseases
Leaf Spot: Leaf spot is a fungal disease that causes brown or black spots on the leaves of Pulicaria leucophylla. The spots may have yellow or brown borders. To manage leaf spot, remove any fallen leaves and destroy them. Avoid wetting the leaves when watering the plant. Use a fungicide spray that contains copper or sulfur to treat the plants.
Powdery Mildew: Powdery mildew is a fungal disease that appears as a white powdery substance on the leaves of Pulicaria leucophylla.

Ensure the plant is watered properly and fertilized regularly. Apply sulphur powder or a fungicide spray containing neem oil.
Pests
Aphids: Aphids are small, soft-bodied insects that feed on the sap of Pulicaria leucophylla. They cause curling or distortion of leaves and can spread viruses that can cause further damage. To manage aphids, use insecticides or a mixture of dish soap and water to spray on the plants. Additionally, introduce natural predators like ladybugs, hoverflies, and lacewings to control aphids.
Spider Mites: Spider mites are tiny insects that feed on the leaves of Pulicaria leucophylla. They can cause yellowing or bronze-colored leaves, and the presence of webs is common. To manage spider mites, wash the leaves of the plant with water and insecticidal soap. Ensure the humidity levels are high and avoid over-fertilizing the plant.
By following these tips and regularly inspecting Pulicaria leucophylla for diseases and pests, you can help maintain the plant's health and prevent any damage.
