Barkdust Reference Overview

In agriculture, gardening, and landscaping, barkdust — also known as bark dust, bark chips, bark mulch, beauty bark, or tanbark — is a form of mulch produced out of chipped or shredded tree bark. Coarser forms of barkdust may be known as bark nuggets.

Sources & Species

Trees typically used in the production of barkdust include the Douglas fir and the western hemlock. Barkdust may be a byproduct of lumber production, of yard debris recycling processes, or it may be produced in its own right. Cedar bark is also commonly used depending on regional availability.

Types & Applications

Barkdust is typically categorised by the source plant and by the coarseness of the resulting material. Fine barkdusts are used as mulch for soil moisture retention and weed suppression. Coarser forms are used for weed control, as a playground surface, or for decorative landscape purposes.

Landscape & Soil Benefits

As barkdust decomposes, it contributes organic matter to the soil, improving structure and supporting microbial activity. It also acts as a thermal insulator for root systems during temperature extremes. Proper depth application — typically 5–10 cm — prevents both moisture loss and root suffocation.
