To Soil Less Founder & Inventor Richard Campbell Explains Gardening With Gravel With Limited Soil and Fertilizer. A few weeks ago I had the pleasure of participating in a To Soil Less class at the Oak Hill Senior Center in Atlanta.\u00a0 I was able to learn about gardening with gravel from To Soil Less founder and inventor Richard Campbell and Sr. Vice President Aaron Short.\u00a0 They had several gardening beds the class has been working on and I was able to sample some of the vegetables.\u00a0 This technique really opened my eyes to a new way of gardening and sustainability. To Soil Less is a family business that was founded by Richard Campbell in 2010. This company was founded to share gravel based growing techniques and practices with the agriculture and gardening communities.\u00a0 Gravel Gardening is a way to grow and sustain vegetables, fruits and flowering plants using nothing more than gravel, sand and cotton based fabric. The use of gravel in the cultivation of crops may represent the most resource efficient method of growing crops ever to exist. The ingredients are all natural and last a lifetime. Geological Agriculture is the process of growing fruits, vegetables and flowers in rock environments. Known also as geo-agriculture or gravel gardening, this method of cultivating crops enables vegetation to occur and sustain itself with limited to no use of soil and fertilizers.\u00a0\u00a0 To Soil less offers several classes around the city of Atlanta and was recently award a grant by Fulton County.\u00a0 Richard Campbell has a book called River Stones Grow Plants, as a personal guide to Geological Agriculture.
