Every stump grinding job leaves a pile of wood chips. A standard 18-inch residential stump produces about 1-2 cubic yards of mulch — roughly enough to fill the bed of a small pickup. What you do with it matters more than most homeowners realize, especially in the Hill Country where oak wilt is a real concern.

Here's the honest breakdown of your four options.

Option 1: Spread It as Garden Mulch (For Non-Oak Stumps)

Wood chips work great as a top-dressing mulch for ornamental beds, around shrubs, and along walking paths. They suppress weeds, slow evaporation, and break down into the soil over 2-3 years.

Caveat: don't dig it into the soil as an amendment. Fresh wood chips temporarily steal nitrogen from the surrounding soil as they decompose — the bacteria doing the breakdown work pull nitrogen out of the soil to do their job. If you spread chips on top of the soil, the nitrogen draw is limited to the surface layer and your plants are fine. If you mix it into the soil as an amendment, you'll yellow out everything in that bed for a season.

Bottom line for cedar elm, mesquite, hackberry, ash, juniper, mountain laurel: spread it on top, 2-3 inches deep, keep it away from plant trunks, and you're good.

Option 2: Don't Spread It — Haul It Off (For Oak Stumps)

This is the big one and it's the rule that surprises most Hill Country homeowners.

If your stump was an oak, the mulch is potentially infectious material. Oak wilt fungus survives in dead wood. If you spread oak mulch on your beds, you've just put a vector for the disease across your entire yard, and worse — every beetle that lands on it can pick up spores and carry them to a healthy oak nearby.

The Texas A&M Forest Service guidance is clear: oak wilt-affected mulch should not be used on residential landscaping. If you're not 100% sure your dead oak wasn't wilt, default to "haul off."

When we grind a confirmed wilt stump, we take the mulch off-property in a contained trailer and dispose of it one of three ways:

Bury deep — at least 18 inches under soil, where temperatures and microbe activity kill the fungus
Burn under permit — Hill Country burn bans permitting, an open burn destroys the spores
Commercial composting — facilities that hit 140°F+ for several days kill the fungus reliably

We charge a small mulch-disposal fee (usually $50-100) on oak wilt jobs to cover this. Worth every penny vs. losing more trees.

Option 3: Use It on Pathways and Drainage

Wood chip mulch makes excellent informal pathway material. It packs down with foot traffic, drains well, and looks natural in a Hill Country landscape. A typical residential stump produces enough mulch for a 30-40 foot stretch of 3-foot-wide path.

It's also useful for filling low spots and routing water — pile it in a depression that holds rainwater, and over a season the wood absorbs moisture and slowly breaks down into soil.

For non-oak stumps, this is the best zero-effort use of the mulch: pile it where you want it, walk on it, done.

Option 4: Have Us Haul It Away

Most of our customers ask us to haul off the mulch even on non-oak jobs. The reason is usually space — a typical Hill Country backyard doesn't have a great spot for a fresh mulch pile, and the homeowner doesn't have a useful project for the chips this week.

We charge $50-150 for haul-off depending on the volume and the landfill we use. If you say "haul it" upfront, we factor it into the quote and it's usually cheaper than figuring out what to do with the pile yourself a week later.

Quick Decision Guide

Non-oak stump, you have flowerbeds: Spread it on top, 2-3 inches, keep it off plant trunks
Non-oak stump, you have a pathway project: Pile it where you want the path
Non-oak stump, you don't want to deal with it: Pay us $50-100 to haul off
Oak stump (any species, any cause of death): Haul off, do NOT spread on your property
Confirmed or suspected oak wilt: Haul off in contained load, professional disposal, no exceptions
