Propagation through Division
Another method for propagating Thermopsis divaricarpa is through division. This method involves dividing the plant's roots and replanting the sections in new locations. The best time to divide the plant is in the spring or fall, when the foliage has died back. The roots should be carefully dug up and separated into small sections, each containing at least one healthy shoot and a portion of the plant's root system. The sections can then be replanted in new locations where they can establish and grow.
Propagation through seeds and division are both effective methods for increasing the number of Thermopsis divaricarpa plants in a garden or landscape. By following the appropriate steps for each method, gardeners can successfully propagate this plant and enjoy its beautiful yellow blooms year after year.
