Before designing this project, we turned to the horticulture experts at our sister publication, Better Homes and Gardens' magazine. They told us what gardener-friendly features to build into the potting bench. A tough top and easy waste disposal were priorities, so we incorporated a galvanized-metal work surface with a handy waste disposal opening over a plastic garbage can. We also added plastic storage bins concealed by doors, a tool rack and overhead shelf, plus wheels and a handle to make the whole setup mobile. We built our bench from rot-resistant cypress, purchasing random-width 4/4 and 8/4 boards and cutting them to the sizes listed. We chose cypress because we found clear, defect-free boards at our local lumber supplier for about the same price as western red cedar. But, to give you options, we sized the parts so you can build the bench from cedar or pressure-treated lumber available in standard dimensional sizes (1x and 2x stock).
