My Black Eyed Susan's are done blooming

I cut mine off when the blooms turn brown .come back every year .

You can cut them back but if you want them to come back in the spring shake some of the heads over that area to drop the seeds.

I am sorry I can not really your answer question, but I have been enamoured by Black Eyed Susans for a while now, so this summer I picked some growing wild in Maine. I planted them in my yard in ME and also in MA and I do hope they come back next year. Most of the ones planted in ME look as though they would grow the last time I was there , but the ones in MA don't look too hopeful. I keep watering them as much as possible with high hopes and cut them back to about two inches to the ground. I think if they can grow in the wild, they can grow in my yard!

Cut them back because they will come back in the spring.

You do not ned to cut them back.The birds will feed off the seeds,and the foliage will die on its own.

It all depends on if you like the texture there for the winter. I do. And as to the next crop, it will come up anyway. You can cut back in the Spring any scraggelies left.
