When is the best time to transplant black-eyed Susans?
Black-eyed Susan’s being a perennial can be divided very early in the spring before the plant has grown and certainly before the blooms have come in. A better time would be in the early fall so they will settle in and root before the winter. Generally, there is a rule of thumb if the perennial blooms in the fall divide and split in the early spring. If the bloom appears in the spring divide and split in the fall. This way the plant will have the most beneficial time in growth.
