Root Division
Erigeron acris L. ssp. kamtschaticus (DC.) Hara can also be propagated through root division. This method is most successful in spring or fall when the plant is not in active growth. The plant should be dug up and divided into clumps with several healthy shoots and a strong root system. The divisions can be planted immediately or potted up and grown on until ready for planting.
Stem Cuttings
Propagation of Erigeron acris L. ssp. kamtschaticus (DC.) Hara can also be achieved through stem cuttings. Cuttings should be taken in the early summer when the plant is actively growing. Cuttings should be 3-4 inches long and taken from healthy, non-flowering shoots. The leaves on the lower half of the stem should be removed, and the cutting should be planted in a soilless mix and kept moist until roots develop.
