Dark Harbor Blend is a dark, rich mixture of soft and hardwood barks that have been allowed to compost naturally for  over 50 years. It is both well decomposed and finely textured and will not rob nitrogen from your soil (as raw mulches may).
Dark Harbor Blend is designed specifically for mulching perennials and annual beds and around roses, shrubs and trees. It is carefully formulated from natural ingredients to provide insulation, weed suppression, excellent drainage and a wonderful source of organic material.
