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 from side to side until the stump is below ground level.
The chips are left in the hole unless you would prefer them removed. Most customers use them to fill the hole, then cover the top with soil.
How Deep Should A Stump Be Ground?
The right stump grinding and removal depth depends on what the ground will be used for afterwards, and we agree it 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 be deeper so a new plant sits in soil rather than wood chips - For a patio, shed base or fence line, the stump must go deeper still, and the surface roots usually need to be followed outward - 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, because a grinder meets a pipe or cable at full speed, and on the older streets in Paris these are rarely where the drawings say - The width of the access, because our smaller machine fits through a standard gate and the larger one does not - Stones or old fence wire inside the stump, which can ruin a full set of teeth
Does The Ground Settle Afterwards?
Yes. After stump grinding and removal the mixture of chips and soil settles over the first year, and you should expect to add more material once.
We recommend mounding the fill slightly above ground level when the work is finished. A hollow that forms later will collect water, and on heavier ground that water sits 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 some help. Wood chips hold very little water, and as they rot they draw nitrogen out of the soil around them, which young trees need.
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.
