How do you guys with gardens stop weeds from overtaking your harvest? I'm talking about a relatively small garden, 20x20. Back in the old days, Dad used to spread his grass clippings between rows to prevent weeds. I've also heard of people using extra roofing shingles as walkways, taking them up year after year. This is a fairly new garden for us (2nd year), so it's fresh soil and the weeds seem to grow overnight. Weeding is a DAILY chore, which in most cases isn't feasable. I'm looking for ideas as to keep the unwanted vegitation to a minimum. Thanks in advance.
