Propagation of Carex muricata L. var. ruthii (Mackenzie) Gleason
Carex muricata L. var. ruthii (Mackenzie) Gleason, commonly known as spiny woodland sedge, is a perennial grass-like plant that can grow up to 1 meter tall. It is commonly found in wetlands, meadows, and woodland habitats across North America. Propagation of this plant can be done through various methods, including seed propagation and vegetative propagation.
Seed Propagation
Seed propagation is the most common way to propagate Carex muricata var. ruthii. The plant produces small seeds that can be collected from the flowers after they have bloomed and matured. The seeds should be sown in a seed-starting mix, and it is recommended to provide bottom heat to encourage germination. The ideal temperature range for germination is 60-70 degrees Fahrenheit.
It is important to note that Carex muricata var. ruthii seeds have a low germination rate, typically around 30%. To increase the chances of successful propagation, it is recommended to sow multiple seeds per pot or tray. Seedlings can be transplanted into their permanent location after they have grown to a sufficient size.
Vegetative Propagation
Vegetative propagation of Carex muricata var. ruthii can be done through dividing the plant's rhizomes. The best time to divide the plant is in the spring when new growth starts to appear. Care should be taken to ensure that each divided section has a portion of the rhizome and a clump of leaves.
The divided sections can be transplanted directly into their permanent location or grown in a pot until they are large enough to be transplanted. It is important to keep the soil moist during the establishment period to ensure successful propagation.
Propagation through cuttings is also possible, but it is not a commonly used method for this plant. If you choose to use this method, take cuttings from the parent plant in the spring or early summer. The cuttings should be planted in a well-draining potting mix, kept moist and placed in a shaded location until they establish roots.
