Non-toxic weed control
We have a pea-gravel covered area in our back yard; this spring the weeds are particularly abundant, so much so that it would take hours to remove them all by hand. Is there an effective non-toxic (as in not toxic to birds, snakes, and other animals but toxic to weeds) solution you recommend? Thank you.

Thank you for your question. Although there are some organic methods of weed control, the timing for you will be a challenge. Corn gluten, when distributed before the seeds germinate, has been shown to be effective with some weeds. The following publication has more ideas (see the tabs, too), but most Extension offices will be reluctant to recommend one or another without knowing what the weed species is. http://npic.orst.edu/pest/weeds.html
If you'd like to bring some samples and/or photos of the weeds you want to eliminate to the Extension office (200 Warner Milne Road, Oregon City), between 9:00 and noon, and 1:00 and 4:00, Master Gardeners there can try to assist in your effort. I hope they can be helpful. Good luck!
