A FINE FIT

October 1, 2025

The smallest bits of wood carry an outsized influence within the mulch and soil industry.  

By growing numbers, bag producers are screening out fines, generally characterized as pieces of wood that are smaller than 1/4 inch, as a matter of cost savings. Fines absorb more water and colorant than the rest of the wood mulch, which adds to the freight cost. The resulting savings in both colorant and shipping makes their exclusion a common practice. 

Another reason for screening fines is that businesses have a use for them. Many bag producers also bag soils and compost, which are perfect fits for fines. A lot of bulk producers, by contrast, do not have another outlet for fines, so they remain in the mulch. 

The inclusion of fines in wood mulch meets a growing consumer demand. The smaller pieces create a more uniform look compared with wood chips that may be several inches long. The industry has responded by shifting to a smaller grind — a trend seen across the country. By some estimates in the Northeast region, as much as 60% of the overall weight of a yard of mulch is fines. 

Mulch producers have multiple financial and consumer considerations to balance when considering how to manage fines. One thing is clear: fines are no small matter.
