Q: I have a large, organic (hopefully) vegetable garden, but I occasionally use Roundup around the edges to keep invasive grasses from creeping in. My understanding is that Roundup is relatively safe and breaks down almost immediately. What are your thoughts on this subject? I totally trust your judgment.

Q: A few years ago, a farmer friend of mine argued that more pesticides and chemical fertilizers are applied to suburban lawns and gardens than are used in commercial agriculture. I can see how this might be the case, given the massive size of the lawn and garden chemical industry, but I haven’t been able to verify this information. Can you help?
