Propagation of Alchemilla cuneifolia Nutt.
Alchemilla cuneifolia Nutt. can be propagated through various methods, which include division, seed, and cuttings.
Division
Division is the simplest and most common method of propagating Alchemilla cuneifolia Nutt. To perform division, the plant should be dug up and the root mass should be divided into sections.
