Are your garden tools in need of a tune-up? Get your tools ready for the growing season with this hands-on workshop co-sponsored by University of Maine Cooperative Extension at Hancock County and NGBH. Our expert instructor, Daniel Cooke, will guide you through the
process of sharpening various tools, including pruners, shears, shovels, and more. Learn proper techniques for maintaining your tools, including how to sharpen, clean, and oil them for optimal performance. This workshop is suitable for gardeners of all skill levels, from beginners to seasoned pros. Bring a favorite tool for show and tell and come prepared to get your hands dirty and leave with tools ready to tackle any
gardening task.


Daniel Cooke has a Master’s in Landscape Architecture from Louisiana State University and a Bachelor’s of Science in Botany from Humboldt State University. After working in the film industry building sets and landscapes for major motion pictures for over 10 years, he and his family moved to Maine.
