Maple Lake Tree Farm, which began as a hobby for Steve and Bev Tenharmsel in 1987 is now a thriving family retail and wholesale business. Over the past 20 years the farm has grown from a six-acre sandy site in Zeeland Township to include a 30-acre clay site two miles west of Hudsonville. The clay soil site produces trees which acclimate well to the clay soil typically found in new developments. In 2000 their son-in-law, Ben Zwageman was hired to help with fieldwork and sales.
