Annual Petunia Planting Day along Bridge Street/US-31 North and South through Charlevoix. Join in the excitement of planting beautiful petunias for locals and visitors alike to enjoy all summer long! Stop anywhere along the route to pitch in; bring gardening gloves and a hand trowel if desired. Once all the petunias are in the ground, visit East Park in Charlevoix's downtown for a complimentary picnic dinner!
