We let our lawn go wild!
When we first moved into our house, the lawn-care guys who had worked for the former owner stopped by to offer to continue their services. When I refused, they said that without their poisons (fungicides, insecticides, and herbicides) and their specially-formulated fertilizer and weed & feed applications that our lawn would die. Well, as it turns out, a few months later some brown spots did develop, but they were soon taken over by other plants, which those lawn guys would probably have condemned as "weeds."
