Propagation of Geranium caespitosum James var. parryi (Engelm.) W.A. Weber
Geranium caespitosum James var. parryi (Engelm.) W.A. Weber, commonly known as the Parry's geranium, is a beautiful perennial plant that belongs to the family Geraniaceae. This plant is native to North America and can be propagated through several methods.
Seed Propagation
Seed propagation is a common method used for Geranium caespitosum James var. parryi (Engelm.) W.A. Weber. The seeds of this plant can be collected in the fall after the flowers have matured. Once the seeds are collected, they can be stored in a cool, dry place until spring.
In spring, the seeds can be sown either indoors or outdoors. For indoor sowing, the seeds can be sown in pots or seed trays filled with a well-draining potting mix. The seeds should be covered with a thin layer of potting mix and kept moist until germination. The seeds typically germinate in 10-14 days.
For outdoor sowing, the seeds should be sown directly in the garden bed after the last frost. The seeds should be sown in well-draining soil and covered with a thin layer of soil. The soil should be kept moist until germination.
Division
Geranium caespitosum James var. parryi (Engelm.) W.A. Weber can also be propagated through division. Division should be carried out in early spring or fall. The plant should be dug up and the root ball should be carefully divided into smaller sections. Each section should have some roots and shoots. The new sections can be replanted in separate pots or directly in the garden bed.
Cuttings
Propagation through cuttings is also possible for Geranium caespitosum James var. parryi (Engelm.) W.A. Weber. This method can be a bit challenging as the plant's stems are woody and may be difficult to root. The best time to take cuttings is in summer when the plant is actively growing.
To take a cutting, select a healthy stem and cut it just below a node. Remove the lower leaves from the stem, leaving only a few leaves at the top. Dip the end of the cutting into rooting hormone and plant it in a well-draining potting mix. The cutting should be kept moist and warm until it roots, which can take a few weeks.
Propagation of Geranium caespitosum James var. parryi (Engelm.) W.A. Weber can be done through seeds, division, or cuttings. Each method has its own advantages and challenges, and the choice of method will depend on the resources available and the specific preferences of the grower.
