The Volume Surprise

First-time clients are often amazed by the sheer volume of material produced. Because grinding introduces air into the wood fibers and blends the wood with native soil, a 24-inch stump often yields a pile of mulch 3 to 4 times larger than the stump appeared above ground.

Option 1: Backfilling the Hole and Natural Settling

Most standard grinding estimates include mounding the chips directly into the cavity left behind. Over 3 to 6 months, as soil settles and organic material breaks down, this mound drops down to level with the surrounding lawn.

Option 2: Using the Mulch in Flowerbeds

Fresh stump chips make excellent weed-suppressing mulch around trees, shrubs, and perennial beds. However, do not mix fresh chips directly into garden soil, as carbon-rich wood absorbs temporary nitrogen as it decomposes.

Option 3: Haul-Away and Clean Topsoil Replacement

If you want immediate turf grass or sod installed, ask your contractor to include chip hauling and replacement with clean screened topsoil in your written estimate.

Frequently Asked Questions

Q:Will the wood chips attract termites?

Termites prefer subterranean colonies and moist, solid structural timbers. Finely ground wood chips dry out too quickly to sustain termite nests, making them safe for landscape use well away from house foundations.

Safety Reminder: Locate Underground Utilities First

Before any stump grinding machine cuts into the ground, contact your regional call-before-you-dig service (dial 811 in the United States or visit clickbeforeyoudig.com in Canada). Always inform your operator of private lines such as sprinkler lines, septic tanks, or low-voltage lighting that public utilities do not mark.
