Growing Black-Eyed Susan

Cut the plants back to the ground in late winter or early spring to promote fresh growth. Divide overcrowded clumps every few years to maintain their vigor.
- Propagation: Black-Eyed Susan can be propagated through division or by collecting and planting seeds. Divide the clumps in early spring or fall by carefully separating the roots and replanting them. Collect seeds from the dried seed heads and sow them directly in the garden or save them for future planting.
