How can I get rid of these Black Eyed Susans?

Question

We moved here about a year ago and the previous owners planted a ghastly amount of "plants" in the front flower beds. I have a number of black eyed susans out there and I'm not big on the wild flower look in front of my house. I dug them up this past winter thinking I got rid of them, but now they've come back with a vengeance!

How can I get rid of these monsters?

Answer 1

The problem with digging them up in the winter is they have already reseeded them selves so even though you got a lot of the plant the seeds are still in the ground.  Spray them all with round up before they go to seed.

Answer 2

maybe dig deeper in the late summer and give or sell them.  they are a favorite to many in the mid-west.
