If you've recently had a tree removed, stump grinding is the next step to reclaim your outdoor space. This blog explains what stump grinding involves, what happens to the roots, and what to expect afterwards. Whether you're worried about regrowth, soil condition or root damage to nearby structures, this guide covers the key facts every property owner should know.
What to Expect After Stump Grinding
What Is Stump Grinding?
Stump grinding is a process that removes a tree stump by using a machine with a rotating cutting wheel to grind it down below ground level. It usually reaches 15 to 20 centimetres deep, which removes the visible stump and allows for replanting or turfing. However, the root system remains underground.
What Happens to the Roots?
Remaining Root System
Stump grinding does not remove the entire root network. Two main types of roots remain:
Feeder roots: small surface-level roots that absorb nutrients.
Perennial roots: larger roots that provide structural support and store energy.
These roots are mostly left undisturbed during the grinding process.
Natural Root Decay
After grinding, the roots begin to break down naturally. This decomposition can take months or years, depending on the tree species, soil conditions, and climate. As roots decay, they return nutrients to the soil, improving its quality for future planting.
Can the Tree Regrow?
Some trees can sprout new growth from remaining roots. This is most common with fast-growing or vigorous species, including:
- Poplars
- Willows
- Maples
- Elms
- Oaks
- Crepe Myrtles
- Chinese Pistache
These species can regenerate even after stump grinding, especially in healthy, fertile soil.
How Soil Fertility Affects Regrowth
Nutrient-rich soil can encourage regrowth by supplying dormant roots with the resources needed to produce new shoots. In contrast, poor soil may reduce the likelihood of regrowth. However, aggressive species may still reshoot in low-quality soil.
Risks from Invasive Roots
Even after stump grinding, some tree roots can continue to grow and cause problems. Invasive root systems may damage:
- Building foundations
- Driveways and pavements
- Underground pipes
- Retaining walls
Species like willows, silver maples, and certain poplars are particularly known for their wide-reaching, intrusive root networks.
Aftercare and Ongoing Management
To manage the area effectively after stump grinding:
- Watch for signs of regrowth
- Apply herbicide if shoots appear (follow local guidelines)
- Improve soil quality with compost or mulch
- Plant shallow-rooted grass or groundcover to stabilise soil
- Avoid damaging nearby trees’ roots during grinding
