My large backyard is constantly infested with weeds. It is mostly grass
rather than lawn. I can't use herbicides because my backyard borders a
wild bird sanctuary and lake. What do you suggest for getting rid of
the weeds? I have used a handy tool called the Weed Popper, but it's
tines are too far apart and often miss the roots of the weeds. Also can
weeds like dandelions reroot themselves if they are left on top of the
ground? Thanks for any advice.

What do the bird sanctuary and lake have to do with prohibiting your use
of herbicides? If you're careful and follow label directions you should
have no problem.
