How Does Stump Grinding Work?
Stump grinding and removal uses a rotating wheel fitted with hardened teeth to cut the stump into small chips. The machine works from the top down and side to side until the stump sits below ground level.
The chips are left in the hole unless you would prefer them removed. Most customers use them to fill the hole and cover the top with soil once the ground has settled.
How Deep Should A Stump Be Ground?
The right stump grinding and removal depth depends on what the ground will be used for afterward, and we agree it with you in writing beforehand:
- For lawn, six to eight inches below the surface is enough, because grass roots are shallow - For a planting bed, the stump needs to go deeper so a new plant sits in soil rather than wood chips - For a patio, shed base or fence line, the stump has to go deeper still, and surface roots usually need to be followed and cut back - If you only want the stump below mowing height, that is a smaller and cheaper job
What Makes Stump Grinding Take Longer?
Three things change the stump grinding and removal price, and it helps to mention them when you call:
- Buried services, since a grinder meets a pipe or cable at full speed, and on older Aurora streets these are not always where the drawings say - The width of the access, because our smaller machine fits through a standard gate while the larger one does not - Stones or old fence wire buried inside the stump, which can ruin a full set of teeth in one pass
Does The Ground Settle Afterward?
Yes. After stump grinding and removal the mixture of chips and soil settles over the following year, and you should expect to add more material at least once.
We recommend mounding the fill slightly above ground level when the work finishes. A hollow that forms later collects water, and on the heavier clay soils away from the moraine that water can sit rather than draining away.
Can I Plant A New Tree In The Same Spot?
You can plant after stump grinding and removal, but the new tree needs a bit of help getting established. Wood chips hold very little water, and as they rot they draw nitrogen out of the surrounding soil, which a young tree needs.
Plant slightly to one side of the old stump if there is room, add fresh topsoil, plant in the fall rather than the spring, and water the new tree through its first two summers.
