It's important to follow the instructions on the fertilizer packaging, as overfertilization can lead to burnt roots.
Pruning of Phagnalon Scalarum Schweinf. ex Schwartz
Phagnalon Scalarum Schweinf. ex Schwartz requires regular pruning to maintain its shape and promote healthy growth. You can prune the plant after the flowering season, which is usually in the fall.
Use sharp pruning shears and remove the dead and diseased branches. Make sure not to trim more than one-third of the plant, as this can stress the plant and delay its growth.
If you notice any diseased branches during the growing season, make sure to prune them immediately to prevent the disease from spreading to the rest of the plant.
Propagation of Phagnalon scalarum Schweinf. ex Schwartz
Phagnalon scalarum Schweinf. ex Schwartz, commonly known as the Tafraoute Fleabane, is a small perennial plant native to the southwestern regions of Morocco. The plant can be propagated through both sexual and asexual means, depending on the propagation objectives and the available propagation resources.
Seed Propagation
Phagnalon scalarum can be propagated from both fresh and stored seeds. The best time to collect seeds is during the summer months when the flowers have dried out, and the seeds are mature. The seeds can be stored for up to one year in a cool and dry place for later use.
The seed germination process can be started by sowing the seeds directly on well-prepared soil during the early winter months. The soil should be moist, and the seedlings should be kept in direct sunlight. Germination usually occurs within two to four weeks. The seedlings should be thinned out when they reach a height of about 5 cm to ensure adequate spacing for each plant to grow well.
Vegetative Propagation
Phagnalon scalarum can also be propagated vegetatively through stem cuttings. The best time for stem cutting propagation is during the early spring when the plant is actively growing.
To propagate through stem cuttings, select a healthy and disease-free stem and cut it about 10 cm below the leaf node. Remove the leaves from the lower half of the cutting, leaving only a few leaves at the top intact. Dip the cut end of the stem in a rooting hormone powder to enhance root development and insert it into prepared soil or a rooting medium, preferably a mixture of sand and peat in a 2:1 ratio.
Water the cuttings with care to avoid dislodging the stem and provide an environment with high humidity for the first two to three months. The cuttings usually develop roots within four to six weeks, and after a few months, they can be transferred to a well-prepared garden or landscape with the right growing conditions.

Pest Management for Phagnalon scalarum Schweinf. ex Schwartz
Phagnalon scalarum Schweinf. ex Schwartz is also susceptible to some common pests that can cause damage to the foliage and stems. These pests can be prevented and managed with some simple strategies.
Aphids
Aphids are tiny insects that suck the sap from the plant's leaves and stems, causing the foliage to curl and turn yellow. These pests are also responsible for transmitting many plant diseases. To prevent aphid infestations, regularly check the plants for any signs of aphids and remove them by spraying with a strong stream of water or applying insecticidal soap. You can also introduce natural predators like ladybugs and lacewings to your garden.
Spider Mites
Spider mites are arachnids that feed on the underside of the leaves, causing them to turn yellow and dry out. These pests are too small to be seen with the naked eye and can spread rapidly. To prevent spider mites, regularly check the plants for any signs of damage and remove them by spraying with a strong stream of water, applying insecticidal soap, or using predatory mites.
Whiteflies
Whiteflies are tiny insects that feed on the foliage and excrete a sticky substance called honeydew, which can lead to the growth of sooty mold. These pests are also responsible for transmitting many plant diseases. To prevent whitefly infestations, regularly check the plants for any signs of whiteflies and remove them by spraying with a strong stream of water, applying insecticidal soap, or using whitefly traps.
In conclusion, by following these simple pest and disease management strategies, you can keep your Phagnalon scalarum Schweinf. ex Schwartz plants healthy and thriving.
