This method is typically used in the spring or early fall when the plant is actively growing. Take a stem cutting that is approximately four inches long and remove the leaves from the bottom of the stem. Dip the cut end of the stem into rooting hormone and plant it in a pot filled with a well-draining potting mix. Water the soil and cover the pot with plastic to maintain humidity. Place the pot in a bright spot, but avoid direct sunlight. Roots usually develop in two to three weeks, and after that, the new plant can be transplanted to the garden.
Final Thoughts
Erigeron aphanactis var. aphanactis is a lovely plant to have in the garden and is relatively easy to propagate by seed or stem cuttings. Whichever method you choose, make sure you take care of the young plants by providing them with the right growing conditions.
