Mulch Program

Most woody plants in our landscapes are native to woodland settings. In the forest, tree roots are covered by a thick layer of decaying leaves, twigs, and branches that are extremely high in essential plant nutrients. This thick layer of nutrient-rich humus is what supports the growth of large trees in areas where the native topsoil may only be a few inches thick and/or of very low fertility. Tree Specialists is now producing our own mulch — Forest Floor Mulch™ Mix — that simulates this natural humic layer.

Forest Floor Mulch™ is produced at our Holliston facility by blending aged woodchips with composed leaf matter. The resulting mixture is then processed in a large grinding machine, producing a finely-textured, natural dark brown mulch. This material closely resembles the composition of the natural humus layer found in our native woodland settings. Advantages include:

  • attractive, natural appearance with no dyes, chemicals or additives
  • conserves moisture without “suffocating” the soil the way bark mulch can
  • breaks down gradually adding valuable organic matter to the soil
  • produced locally for local use
  • boosts soil biology for enhanced plant growth

Mulches vary in color, texture, and composition. Most are by-products of the logging industry and are made of bark, wood pulp, and even scrap lumber. Many are sprayed with dye to create reddish, brown, or black hues. They may be decorative, but they are poor sources of organic matter required for woody plant nutrition.

As an ecological landscape architect, I have long appreciated the very knowledgeable advice Tree Specialists has given me and my clients about how to keep our trees healthy. Rolf Briggs and his crew of trained arborists are completely professional in their business practices and deeply passionate about nurturing trees in wild and managed landscapes. I trust them to do any tree-care job right.— Sue Reed, Landscape Architect, Principal, Susan Reed Associates, Shelburne Falls, MA
