Stump Grinding in Andover, MA

What is stump grinding?

Stump grinding uses a machine with a rotating, toothed cutting wheel to chip a tree stump into small pieces below the soil surface. The wheel sweeps back and forth across the stump, working down a few inches at a time, until the wood is ground to the agreed depth. Major surface roots near the stump can be ground out too.

Grinding leaves the deeper root system in the ground, where it slowly decays. That’s the difference between grinding and full stump removal, which digs out the entire root ball. For most yards, grinding is faster, cleaner and far less disruptive. It’s the usual finishing step after tree removal, and a common follow-up to local tree pruning and removal work in Andover.

Stump grinding vs. stump removal

Why grind a stump instead of leaving it?

• Safety: stumps hide in long grass and trip people and mowers.
• Sprouts: many species, including maples, cherries, black locust and some oaks, send up shoots from the stump and roots for years.
• Pests: decaying stumps can attract carpenter ants and wood-boring insects.
• Fungus: stumps can host root-rot fungi that may spread to nearby trees through roots.
• Space: grinding returns the ground to lawn, garden or a new tree.
• Looks: a clean, level yard instead of an old stump.

What are the signs a stump should be ground?

1. Shoots keep sprouting from the stump or nearby roots
2. Mushrooms or fungal growth appear around the stump
3. Ants or other insects are active in the decaying wood
4. You’re mowing around it or have hit it with the mower
5. Surface roots are lifting the lawn or a path
6. You want to replant in the same area
7. The stump sits where you plan a patio, bed or play area
8. It’s an eyesore at the front of the property

How deep does stump grinding go?

Most residential grinding goes several inches below the surrounding grade, enough for sod or seed to grow over. If you plan to plant a new tree or shrub in the same spot, ask for deeper grinding and removal of chips from the hole, since fresh wood chips mixed into soil tie up nitrogen while they decompose. Planting slightly to the side of the old stump, in undisturbed soil, is often the best option.

What about underground utilities?

Grinding is a form of digging, and Massachusetts requires a call to Dig Safe (811) before excavation so underground gas, electric and communication lines are marked. Private lines, such as irrigation, lighting cables, invisible dog fences and septic lines, aren’t marked by Dig Safe, so point them out before work starts.

Which roots should be ground?

Surface roots that lift the lawn, trip people or interfere with mowing can be ground out several feet from the stump. Deeper roots are left in place to decay. Grinding roots near a tree you’re keeping is a different matter: cutting major roots can destabilize or stress that tree, so only roots from the removed tree should be ground.

What can you do before the grinder arrives?

• Clear rocks, toys, garden ornaments and debris from around the stump.
• Mark irrigation heads, lighting cables and invisible fence wires.
• Make sure there’s a path wide enough for the grinder, usually a standard gate opening.
• Decide what you want done with the chips.

Why do Andover yards end up with so many stumps?

Over the last decade, emerald ash borer has killed ash trees across Massachusetts, and many Andover properties have lost one or more ash to it. Storms take down weakened trees every few winters, and new construction on wooded lots in parts of town leaves rows of stumps along driveways and lot lines. Many of those stumps were left behind when the trees were cut, and they’re still sprouting, rotting or catching mowers years later.

Stumps from different species behave differently. Maple, cherry and black locust stumps are notorious for sprouting from the roots. Oak stumps are dense and slow to grind but rarely send up much regrowth. White pine stumps resist rot because of their resin, so they can sit for many years if left alone. Ash stumps from trees killed by emerald ash borer are usually dry and grind quickly.

Grinding is also the step that makes replanting practical. Andover has lost a lot of canopy to pests and storms, and putting a well-chosen tree back near the old spot restores shade and value. Grinding first clears the old wood and gives the new tree’s roots room to spread. It also removes a common source of decay fungi that can move through soil to nearby trees, which matters on lots where other mature trees are close by.

How does a stump grinding visit go?

1. Locate utilitiesDig Safe markings are checked and private lines identified.
2. Clear the areaRocks are removed from around the stump, which could damage the wheel or be thrown.
3. Set up shieldsProtective barriers guard windows, cars and plants from flying chips.
4. Grind to depthThe wheel works across the stump and main surface roots to the agreed depth.
5. BackfillChips are raked into the hole, or removed and replaced with topsoil if you’re planting.
6. Clean upChips are cleared from lawns, beds and hard surfaces.

What affects the cost of stump grinding?

What happens after grinding?

The ground settles slightly as the chips and buried roots decompose, so expect to top up with soil after a season. For a lawn, rake out excess chips, add a few inches of topsoil, level it and seed or sod. For a garden bed, the chips can work as mulch around plants. If you’re putting a new tree in, our guide to the best trees to plant in Andover suggests species suited to local soils.

Can you grind stumps in winter?

Yes, as long as the ground isn’t buried in deep snow and the machine can reach the stump safely. Frozen ground can even help on soft lawns, because the grinder’s wheels leave fewer marks. The one catch is replanting: you’ll want to wait for spring or early fall to plant a new tree in the spot, and to seed or sod the patch once soil can be worked.

Is a stump ever an emergency?

Rarely, but a large stump with active root-rot fungi near other valued trees, or a stump hollowing out under a walkway, is worth dealing with soon. After storm removals, stumps are often left until the urgent work is done and then ground in a follow-up visit.
