Cultivation Methods
Pulicaria arabica is a perennial plant that prefers well-drained soil rich in organic matter. It thrives in full sun and can tolerate high temperatures and drought. The best time to plant it is in the spring.
The plant can be propagated from seeds or cuttings. If using seeds, it's best to sow them directly into the garden bed after the last frost. Cuttings should be taken in the spring or early summer and planted in a well-drained potting mix.
Watering Needs
Pulicaria arabica is drought-tolerant, but it still needs adequate water to grow. The soil should be kept moist but not waterlogged, especially during the first growing season.
Water the plant deeply once a week, or more often if the soil is dry to the touch. However, avoid overwatering as this can cause root rot and other fungal diseases.
Fertilization
Pulicaria arabica does not require heavy fertilization, but applying a balanced, slow-release fertilizer once or twice a year can improve its growth and vigor.
Use a fertilizer with a ratio of 10-10-10, which contains equal amounts of nitrogen, phosphorus, and potassium. Apply according to the manufacturer's instructions and water thoroughly after application.
Pruning
Pulicaria arabica does not require heavy pruning, but deadheading spent blooms can encourage more flowers to grow.
In the fall, cut the plant back to remove any dead or damaged stems. This will promote new growth and help the plant maintain its shape.
Propagation of Pulicaria arabica (L.) Cass.
Pulicaria arabica is a species of flowering plants in the family Asteraceae. It is a perennial shrub that is native to Arabia, Africa, and Asia. Propagation of Pulicaria arabica can be achieved through various methods, including seed propagation, stem cuttings, and division.
Seed propagation
The propagation of Pulicaria arabica can be achieved through seeds. The best time to propagate the plant through seeds is during the spring season. The seeds of the plant can be collected once they have fully matured and turned brown. The collected seeds should then be sown in a well-prepared seedbed and then covered with a layer of soil.
The seeds should be watered regularly, and after a few weeks, the seedlings will start to appear. The seedlings can then be transplanted into individual pots or containers, and once they have developed a strong root system, they can be planted in their permanent location outdoors.
Stem cuttings
Propagation through stem cuttings is another viable method for Pulicaria arabica. The best time to take stem cuttings is during the early summer months. The cuttings should be taken from the softwood stems and should be about 10-15 cm long.
The cuttings should then be planted in a well-prepared rooting medium and kept in a warm and humid environment until the roots have developed. Once the roots have developed, the new plants can be transplanted into their permanent location outdoors.
Division
Pulicaria arabica can also be propagated by division. This method involves dividing the mature plant into smaller sections, each of which will grow into a new plant.
The best time to divide the plant is during the early spring season when the plant is just beginning to emerge from dormancy. The mature plant should be carefully dug up from the ground and divided into smaller sections, each of which should have a healthy root system.
The divided sections should then be planted in a well-prepared location outdoors. They should be watered regularly until they have established a strong root system.
