Coast of Maine Organic and Natural Compost with Lobster and Crab is our locally renowned “seafood” compost. Its crustacean shells are nurtured in our home state’s cold, dark waters, granting the botanical benefits in this multi-use mix that first established Coast of Maine’s fame. This precisely-balanced formulation helps to revitalize soil and provides the needed balance of water retention, drainage, and aeration. It is ideal for maintaining gardens, beds, and borders and nurturing the robust growth of vegetables, flowers, and foliage.
