Propagation of Equisetum arvense L. var. alpestre Wahlenb.
Equisetum arvense L. var. alpestre Wahlenb., commonly known as alpine horsetail, is a perennial plant that reproduces both sexually and asexually. The plant can be propagated through various methods, including spores, rhizome cuttings, and division.
Propagation by Spores
Propagation by spores can be a time-consuming process, requiring specific conditions for germination. Spores should be collected from mature plants during the summer months and sown in a well-draining potting mix. The pot should be kept moist and placed in a shaded area. It may take several months for the spores to germinate, after which the young plants can be transplanted to a larger pot.
Propagation by Rhizome Cuttings
Propagation by rhizome cuttings is a faster method than spore propagation. Rhizomes should be collected during the plant's dormant season (late fall or early winter) and cut into sections with at least one bud. The cuttings should be planted horizontally in a well-draining potting mix and kept moist. The pot should be kept in a shaded area until the cuttings have developed roots and new growth.
Propagation by Division
Propagation by division is the easiest and fastest method for propagating Equisetum arvense L. var. alpestre Wahlenb. The plant's rhizomes can be dug up, and the plant can be divided into sections, each with its roots and shoots. Each section can be replanted in a suitable location with well-draining soil and plenty of moisture.
Regardless of the propagation method chosen, it is essential to keep the plants well-watered and in shaded areas until they are established. Proper care and attention will ensure that the plant thrives and produces new growth.
