Title: Should black-eyed susan (Rudbeckia hirta) plants be cut back
Answered by: Nan Hampton and Joe Marcus
QUESTION:
I have black-eyed susan plants that were beautiful last year and flowered for a long time. Do they need to be cut back and if so, how much?ANSWER:
It isn't really necessary to cut back Rudbeckia hirta (blackeyed Susan); but if you will deadhead them (i.e., remove the fading flowers before they set seed), it will prolong their flowering period.
