Stump grinding is a great way to deal with a leftover stump. However, since the process leaves the roots largely untouched, you might be wondering, “What happens to roots after stump grinding?”
You are not alone. This is a question many homeowners ask us when scheduling these tree services in Cordova, TN. Thankfully, we’ve got the answer.

Understanding the Stump Grinding Process
First, we need to delve into what the grinding process entails. After all, grinding a leftover stump only shreds visible evidence of the stump. The roots that have spread underground aren’t affected, at least not directly.
Stump grinding involves the use of a specialized machine to break down a leftover stump, shredding it into sawdust or small wood chips. The machine grinds the stump down to 6 or 12 inches below the ground, helping you reclaim your yard.
While the grinder might graze the uppermost part of the stump’s root system, it doesn’t reach the depths where most of the roots are. So, what happens to tree roots after stump grinding?
Effects of Stump Grinding on Underground Roots
While stump grinding doesn’t focus on the underground roots, it doesn’t mean the process has no impact. So, do roots die after the stump grinding process?
The short answer is yes, the remaining roots die and decompose over several years. This is because insects and soil organisms like fungi and bacteria help break down the roots’ organic matter, further facilitating their natural decay.
This is great news not only for you but also for the soil and surrounding plants.
How Long Do Roots Take To Decay After Stump Grinding?
Unlike grinding down a stump, which is often quick, root decomposition takes several years. Ultimately, how long the process lasts will come down to several factors.
Type of Soil
Is the soil rich and loose or heavily compacted? Since rich, loose soil allows more organisms to thrive, the leftover roots decay much faster here than they do in compacted soil.
Tree Type
The tree type also determines how quickly roots decay. Hardwood trees like oak tend to have tough, resilient roots that can take a long time to decompose. However, if the tree had softer wood, the roots would likely break down faster.
Root Size
The larger and more widespread the roots are, the longer they will take to decompose.
Climate
When compared with warm, wet weather, cooler and drier climates tend to slow down the decomposition process.
