Getting rid of established perennial weeds and grasses
I had an erroneous vision of a slope planted with daffodils and daylilies which would naturalize and increase over the years. What I didn't understand was that there were farmland grasses and weeds that grow very tall in that same area and obscure my plantings. I'm trying to figure out what my options are to get rid of these established weedy plants while not harming my other plantings. Daffs are barely poking above ground at this point.
