I'm in Minnesota, which I believe is Zone 4 for the most part. Like a lot of
people, crabgrass is a part of my lawn. Overall the lawn looks pretty good,
but the crabgrass is encroaching.

Is there any way to poison or kill the crabgrass at this time of year? Or
did I miss my chance in the spring?

There's too much to spray with one of those Windex-type bottles of Ortho or
something, so is there some kind of broadcast spray that will only kill
crabgrass?

Thanks!
