Soil Requirements
Agoseris glauca var. laciniata grows well in well-drained, sandy or loamy soils. The plant can tolerate alkaline soils but prefers slightly acidic soil with a pH between 6.0-7.5. To ensure healthy growth, the soil should be rich in organic matter and should retain moisture well.
Cultivation Methods
Agoseris glauca (Pursh) Raf. var. laciniata (D.C. Eat.) Smiley prefers well-draining soils and grows well in full sun. It is a hardy plant that can tolerate drought once established. It is recommended to plant them in the garden in late spring or early fall, and spacing should be about 18 inches.
Watering Needs
The plant should be watered regularly during the first few weeks after planting to help establish the roots. After that, watering should be reduced to once a week, and only if the soil appears dry. Overwatering can cause root rot, so make sure not to let the plant sit in standing water.
Fertilization

The sections should be replanted in a suitable location and kept moist until they become established.
Cuttings
Propagation through cuttings is a relatively challenging technique for Agoseris glauca (Pursh) Raf. var. laciniata (D.C. Eat.) Smiley. Cuttings should be taken from new growth in the spring or early summer when the plant is actively growing. Cuttings should be about 5-7 cm long and dipped in rooting hormone before being planted in a well-draining soil mix. The cuttings should be kept moist and protected from direct sunlight until they become established.
Conclusion
Propagation of Agoseris glauca (Pursh) Raf. var. laciniata (D.C. Eat.) Smiley can be done through various methods, including seed propagation, division, and cuttings. However, the best method depends on the individual plant and its growing conditions.
