So much depends on what kind of weeds, your ultimate plans for the area, and so on...
We've had several good, recent discussions on attacking weeds (or not). Unfortunately, they're in several sections of the forum, so the best way to find them right this minute would be to use the Search function on the top left-hand corner of the page. (I just did, to make sure it would yield helpful results.) When I tried the words "manage weeds," I didn't get the results I was looking for.
But simply "weeds" brought up most of the recent threads I had in mind.
Hope it works for you, too!
