I've got some old daylilies that keep coming back in my raspberry

without uprooting all the raspberry canes. Although I've always had an
organic garden I'd like to try hitting them with Roundup but I am
wondering if it will kill the raspberries as well, since they are both
spreading plants and completely intertwined.


Get a foam paintbrush and apply a little Roundup concentrate to the
daylily leaves with that. Don't get any on the raspberries. I do that
with dandelions or perennial grasses that come up in the middle of other
plants.

There are a few herbicides that will be released in the soil when the
affected plant dies and poison the surrounding plants (mostly broadleaf
weed killer, I think), but Roundup is not one of 'em.
