You can obtain cuttings during the spring or summer season from healthy and mature plants. Cut a stem segment about 4 inches long that contains at least two nodes. Ensure that you make the cut below a leaf node and that the cutting has some leaves on it. Dip the cut end of the cutting in rooting hormone, then plant it in a well-draining soil mixture. Cover the cuttings with a plastic bag to create humidity and retain moisture levels.
Division Propagation
Division propagation is the easiest and quickest method to multiply Eupatorium mohrii plants. The best time is during early spring when you see new growth emerging. Gently dig up the plant and divide the root ball into smaller sections, ensuring that each section has several stems and a good root system. Replant the divisions in a well-draining soil mixture and water them thoroughly. Divisions should not be left exposed in the sun as their root systems may not be extensive enough to get enough water and nutrients.
With these propagation methods, you can easily propagate Eupatorium mohrii Greene and add more of this lovely plant to your garden.
