also this doesn't mean that I "NEVER" use any chemicals, it's just that I think twice about when, where, and why, and do I really need to. Not chastizing the use of chemicals, because I do use them too, mainly pre-emergent which keeps the lawn and cultivated flower gardens nice and Roundup on paths when weeds and grasses get out of hand (Roudup actually readily breaks down in the soil after application)just consider other tools and options first too.
