Propagation of Hieracium scabrum Michx. var. scabrum
Hieracium scabrum Michx. var. scabrum, commonly known as rough hawkweed, is a perennial plant species that belongs to the Asteraceae family. It is a native plant of North America that grows well in meadows, prairies, woodlands, and disturbed areas. Propagation of Hieracium scabrum Michx. var. scabrum can be done through several methods.
Propagation through Seeds
Seeds are the most common method of propagation for Hieracium scabrum Michx. var. scabrum. To propagate through seeds, collect the mature seeds from the plant when they are dry. Sow the seeds in a well-draining soil mix, and keep them moist until they germinate. The seeds take about 2-3 weeks to germinate, and the seedlings can be transplanted to their permanent location after 6-8 weeks. The best time to sow the seeds is in spring or fall.
Propagation through Division
Hieracium scabrum Michx. var. scabrum can also be propagated through division. Divide the plant in late spring or early fall, when the plant is not actively growing. Dig up the plant and carefully separate the roots into sections, making sure each section has a portion of the crown and roots. Replant the sections in their permanent location, making sure to water them well. The divided plants should be kept well-watered for the first few weeks until they become established.
Propagation through Cuttings
Propagation through cuttings is another option for Hieracium scabrum Michx. var. scabrum. Take cuttings of healthy stems that are about 4-6 inches long. Remove the leaves from the bottom half of the stem, and dip the cut end into rooting hormone. Plant the cuttings in a well-draining soil mix, and water them well. Place a plastic bag over the cuttings to create a humid environment, and place them in a bright but indirect light. The cuttings take about 4-6 weeks to root, and they can be transplanted to their permanent location once they are well-rooted.
Disease and Pest Management for Hieracium scabrum Michx. var. scabrum

Bacterial leaf spot is another common disease that affects Hieracium scabrum. Bacterial leaf spot appears as water-soaked spots on the leaves. The spots will enlarge and turn brown, and the leaves will fall off the plant. To manage bacterial leaf spot, remove and dispose of infected plant parts. Apply a copper-based fungicide early in the growing season before the disease appears. Keep the area around the plant clean and dry.
Common Pests
Aphids are one of the most common pests that affect Hieracium scabrum. Aphids are small, soft-bodied insects that suck plant sap and secrete honeydew, which can attract ants and promote fungal growth.
