I'm planting a small butterfly garden at a public elementary school in Vancouver WA along a fenceline which is sprayed occasionally. We're planning on putting up signs that mark off an area surrounding the garden which is not to be sprayed. My question is, how far away from the edge of the garden should the signs be? 20 ft? 50 ft? How far can herbicide travel in enough quantity to effect plants, butterflies, and caterpillars? Unfortunately, I don't think it will go over so well if I mark off the entire school fenceline with these signs. thanks, Matt -- Matt Gordon Habitat Environmental Education Liaison Program (HEELP) Sponsored by Habitat Partners & Northwest Service Academy's Lower Columbia Center Located at the Youth House (12th & Columbia) -- 360 693-8013 voice 503 310-5766 cell 360 397-2164 fax email@example.com
