Is My Rudbeckia Dead. Aim to water well and occasionally rather than little and often. They break dormancy the first year and flower the next.
I planted 3 seed grown Rudbeckia hirta this year in this bed near my mailbox. Why is my rudbeckia dying. Cut off faded and wilted Black Eyed Susan blooms throughout the growing season to keep the plant tidy and in control.
Some of the stalks and flowers seem to be wilting before they turn brown though.
When this disease appears in a garden remove and discard in the trash. Where the damage is more severe you may need to accept that the position of your Rudbeckia fulgida plants is just too damp. I planted 3 seed grown Rudbeckia hirta this year in this bed near my mailbox. On Rudbeckia that grow a single flower on each stem cut the stem back to the base of the plant.
