Mulch - What’s the Difference between the two?
Arborist Mulch is the product that comes out of the chipper.
It consists mainly of tree & brush components 18 inches or less.
It often contains leaves, pine cones, needles, wood shavings, sticks and other tree parts.
In the winter, the quality of Arborist Mulch is more woody because the leaves are absent.

Fresh Arborist Mulch can also contain, insects, seed pods, fungus &/or diseases.
For this reason, we recommend only using Composted Arborist Mulch.
Composted Mulch is a darker brown color while Fresh Mulch is usually much lighter.

By allowing the mulch to compost in a pile, it generates heat during the decomposition
process and thereby sterilizes itself. Not only do the leaves and other green matter break
down, the heat generated during the composting process is usually enough to destroy any
insects and/or pathogens that may have been present.

When you ask us to leave you a truck full of freshly made wood chips, it is a good idea to
let the pile sit for a while to allow it to compost before applying it unless you know there
are no insects, seed pods or pathogens present to cause you trouble.

It is not uncommon for a mulch pile to give off steam due to the heat generated during
decomposition. We once had the fire department contact us thinking our mulch pile was
on fire because it was steaming so much. We stirred the pile around with our dozer, and
assured them as was well.

The Shredded Mulch produced by our Tub Grinder will respond in much the same way.
It will darken over time from composting and will also generate heat. The main difference
being what it was made from – if it was composed of nothing but logs, stumps & chunks of
wood, the quality will differ from something composed of brush & branches.

We sell our Composted Arborist Mulch for $20 per yard

We sell our Aged Shredded Mulch for $25 per yard.

Both Prices are PLUS Delivery and Sales Tax.

Shredded Mulch Packs better and holds in place better on a slope. It doesn’t blow
around as much as Arborist Mulch which is looser and fluffier. Arborist Mulch is better
for building the soil and is a great addition to your plant beds that need organic matter.

Personally, I prefer to use Composted Arborist mulch for a base approx. 3 inches thick
the first and second seasons to build the soil, then I top dress it with Shredded Mulch
the third season and refresh ever other year thereafter.
