Our Favorite Plants for Wet Areas in Coastal Maine Landscapes

Water tolerant plantings are ideal for yards with poor drainage or consistently wet soil. If you have a soggy patch in your yard that never dries out, adjusting your landscaping to include water tolerant plantings can help. Many coastal Maine properties face wet areas caused by poor drainage, high water tables, or proximity to the ocean. Instead of fighting it, you can embrace it with plants that thrive in damp, salty conditions.
At Garden Guys Landscaping, we design with the local environment in mind. That includes choosing plants that do well in saturated soils, tolerate salt exposure, and fit the unique challenges of Maine’s coastal landscapes. Plant selection for wet sites is often based on soil drainage, water tables, and native habitat research. Below are some of our favorite plants for wet areas in coastal Maine yards.
