Only native Monarda come true from seed. Propagating Monarda hybrids is easy by division. They should be divided every one to three years. The best time to divide them is in early spring just as the new growth is emerging. Dig up the plant and cut it into sections with a sharp spade. Sometimes you will see the growth on the soil surface and you can just pull the little plantlets apart. Take divisions from the newest growth at the outside of the clump and plant them right away like you would a bare root plant.
