Neighbors who use pesticides
I live in an suburban area with nearly a half of an acre. I believe in organic, pesticide free gardening. My concern is that my neighbor uses some kind of chemical treatment of their lawn. I see the chemical truck parked outside of their house every month. I am afraid that my organic gardening is not really organic. How far does the pesticide leach from someone's land? How far should my garden be from their pesticide-laden grass?
