Propagation of Haplopappus Croceus Gray ssp. Typicus Hall
Haplopappus croceus Gray ssp. typicus Hall, commonly known as the San Bernardino goldenbush, is a deciduous perennial shrub that is native to southern California. This plant species can be propagated through several methods.
Seed Propagation
One of the easiest and most common methods of propagating Haplopappus croceus is through seed propagation. The seeds can be collected from the matured plants during the late summer or early fall months. The seeds should be stored in a dry and cool place until they are used for propagation.
The seeds should be sown in a well-drained potting mix that is moistened. Cover the seeds with a thin layer of soil and keep them in a warm and bright location. The seeds should germinate within three to four weeks. Once the seedlings have two leaves, it is time to transplant them into individual pots or into the ground.
Cuttings
Another method of propagation is through cuttings. Select a healthy stem, free of disease and pests. The stem should be approximately six inches long, and the cutting should be done during the spring or early summer months.
The bottom leaves from the cutting should be removed, leaving only the top two or three pairs of leaves. Dip the cut end of the stem into rooting hormone and plant it in a well-drained potting mix. Place the pot in a warm and bright location and keep the soil moist. The cutting will start rooting within several weeks.
Division
Haplopappus croceus can also be propagated through division. However, it should be noted that this method is not recommended for maintaining the genetic diversity of the plant. The best time for division is during the early spring months.
Carefully dig out the plant and shake off any excess soil. Cut the plant into several sections, making sure that each section has a healthy root system. Plant each section in a well-drained soil mix and provide adequate watering and sunlight.
Propagation of Haplopappus croceus can be an enjoyable experience, and you can use any of the above methods to grow this beautiful plant.

Additionally, providing proper ventilation and spacing between plants can help reduce the spread of the disease. Fungicidal sprays may also be effective in treating powdery mildew.
Rust can be treated similarly to powdery mildew, with affected material removed and proper spacing and ventilation provided. Fungal sprays can also be effective against rust.
Pests
One common pest that can affect Haplopappus croceus is the aphid. Aphids are small insects that suck the sap from plant leaves, leading to stunted growth and distorted leaves. Additionally, spider mites can also infest Haplopappus croceus, creating a fine webbing and damaging the foliage.
To manage aphids, introducing natural predators such as ladybugs or lacewings into the garden can be effective. Additionally, sprays containing insecticidal soap or neem oil can also be used to control aphids.
Spider mites can be treated through proper irrigation, ensuring that the plant is receiving enough water and staying hydrated. Insecticidal soap sprays can also help control spider mites.
