Landscaping that compliments natures design It all started when. . . Since Bob Nelson Farmer began Gristmill landscaping in 1985, his philosophy has always been to work with nature, not against it. He has built a reputation for having a vision to see the most potential a landscape has to offer. Many of his designs have been shown in magazines, other publications, and H. G. T. V. , much to the delight of his clients. A look through his portfolio will tell you this is not just a business but a love of what he does. Bob's longtime staff are in tune with his visions and work ethics; to create a seamless flow on all their projects. Gristmill's habitat is a restored 150 year old former working gristmill in Jarrettsville
