The gardens in the Watershed tour features gardens that were created and maintained by the garden owners. The seven gardens in this year’s tour are as varied as the gardeners.

Each year, the GRLT hosts the Garden Tour in a different section of the watershed to introduce garden visitors to the diversity and beauty of the landscapes along the St. George River from Montville to Port Clyde. Proceeds from the tour help the Land Trust’s work to conserve and steward natural resources and traditional character of the region. The Land Trust has conserved over 4,000 acres of farms, wildlife habitat, wetlands, and shoreline along the 51-mile-long St. George River.
