My Yard Our Sound!

Are you interested in turning part of your yard into a butterfly, bee, and bird-friendly habitat that helps keep our waterways clean?

The Maritime Explorium is offering free workshops to provide resources on how to turn your lawn into a garden without breaking your back or the bank. The bonus? If you meet the requirements of the project, you can receive a $50 reimbursement towards the purchase of appropriately-sourced native plants!
