I'm new,sorry..Is it ok to leave this concoxtion on the plants or should I wash it off? I used "milky spore" in my vegetable garden last spring and it worked great (the beatle have completely avoided it)but I have way too much area to cover and simply can't afford to use it in the rest of the yard.If anyone has a homemade recipe for either of these raveging beast please e_mail or post..thanx so much«craig
