Before purchasing mulch, do some research on the best type for your project. Backyard Boss explains that there are several types available, including standard garden, rubber, bark, hardwood, hemlock, and mulched leaves.[1] Each type has a different look, so spend some time to find the right variety to complement your home and landscaping. Different types also cost more than others, which may be an important factor in your decision. In addition, different types may be finer or coarser in texture, which will impact how much of them you may want to use. Rubber mulch being heavier and thicker generally requires less to fill the same area than standard garden mulch, for example.
