, fellow Hoosier! It is not easy to keep weeds out. I have been on my knees digging out wild violets a lot this year.
I have also been known to just dig up the clump of daylilies, separate the fans as much as possible, wash them very well to get as many of the weed seeds out, and then plant in a new spot.
It certainly is a constant battle no matter what kind of plant you have.
