While Windmill Island Gardens does not open for the 2026 season until Monday, April 13,  they are still thinking spring! Starting March 19, Windmill Island Gardens is launching an all-new monthly  gardening class series geared towards those who are ready to dig-into gardening at home! In partnership  with the Michigan State University Extension, Windmill Island Gardens is excited to host a variety of  classes covering topics like site assessment, composting, starting a vegetable garden, design tips,  preserving and canning, trees, and so much more. Learn from the experts at these once a month classes  from March – October on the third Thursday of the month from 6:00pm – 7:30pm for just $15 a class, or  save $20 when you sign up for them all for $100! 

Are you planning new garden plantings this season? Or trying to determine why certain plants aren’t  thriving in your landscape? Beautiful gardens start from the ground up! On Thursday, March 19 from  6:00pm-7:30pm Windmill Island Gardens will host the first De Tuin Klas (The Garden Class) where  Deanna F. Hedlund, MSU Extension Horticulture Educator, will help you better understand your existing  site conditions before you start to make potentially costly changes, including soil testing options and what  the test results can mean for your landscape. You will leave this class armed with a site assessment  checklist, pH testing strips to take home, and knowledge to give your plants the best chance of  flourishing! 

“Helping the community learn how to garden in a way that feels both authentic to them and is rooted in  evidence is a personal goal of mine.” Says Windmill Island Gardens Grounds and Horticulture Manager,  Emily VanStaalduinen. “I'm really excited for these classes, especially for young homeowners or those  who are newer to gardening. Not only can your garden be your personal refuge, but also a refuge for  native wildlife and your neighbors if done intentionally. And what better place to share this information  than our beautiful gardens at Windmill Island!” 

De Tuin Klas: Ground Rules will be held at Windmill Island Gardens in the white Celebration Pavilion (1  Lincoln Ave, Holland, MI 49423). Class fees are $15 per person and include all needed supplies. Tickets  are non-refundable. For questions about De Tuin Klas Series, please contact Laura at  l.ambruso@cityofholland.com. Space in each class is limited, so secure your spot today! 

The full schedule of De Tuin Klas series can be found below with more information available about other  upcoming programming on the Windmill Island Gardens Facebook page and at  www.windmillisland.com/programs.
