I’m an Ontario-based garden writer and horticulturist and I love gardening and all things related to gardening, especially soil health. The list is endless: ecology, garden design, philosophy, health, plant physiology, soils, microbiology, environmental issues etc. For me gardens & gardening are the centre of myriad discussions.

See some of the discussions on my Facebook fan page .

Join me in the grand adventure in learning how to build a better garden through healthy soil.
