Whether you’re redesigning your landscape or clearing space for new plants, removing bush and shrub roots is often a necessary but challenging task.
Many homeowners make the mistake of simply cutting down bushes without addressing the underground root system. Unfortunately, if roots are left behind, they can lead to regrowth, interfere with new landscaping projects, or even damage underground structures.
This guide will walk you through everything you need to know about removing bush and shrub roots from the tools you’ll need to the safest and most effective methods to get the job done right.

Why It’s Important to Remove Bush and Shrub Roots
When you remove only the visible portion of a bush or shrub, the root system remains intact underground. Here’s why that can be a problem.
Regrowth
Many shrubs can regrow from the remaining root system, causing the same issue to return within months.
Pest Attraction
Decaying roots can attract pests such as termites and carpenter ants.
Obstruction
Roots may interfere with replanting, lawn work, or the installation of new structures like fences, patios, or driveways
Drainage Issues
Leftover roots can clog drains or disrupt natural water flow.
Tools and Supplies You’ll Need
Depending on the size and depth of the root system, you may need a variety of tools.
Here’s a basic list to get started:
- Work Gloves
- Protective Eyewear
- Spade Shovel
- Pruning Shears
- Loppers
- Mattock or Pickaxe
- Root Saw or Reciprocating Saw
- Chainsaw (For Larger Shrubs)
- Heavy-Duty Tarp or a Wheelbarrow
- Garden Hose or Pressure Washer
- Stump Grinder (Optional for Large Shrubs)
- Chemical Root Killer (Optional)
Step-by-Step Guide to Removing Bush and Shrub Roots
Step 1: Cut Down the Shrub
Start by cutting back the bush as close to ground level as possible. Use loppers or a pruning saw to remove branches and stems and a chainsaw for thicker trunks.
Remove as much foliage as you can—this reduces the root system’s access to nutrients and makes the root ball easier to handle.
Step 2: Dig Around the Base
Use a spade shovel to dig a trench in a circle around the base of the shrub. Aim for a radius of 12 to 24 inches depending on the size of the bush. This will expose the main roots and give you access to the root ball.
Try to dig deep enough to see the major roots clearly—about 12 to 18 inches for most shrubs.
Step 3: Loosen the Root Ball
Using a mattock, pickaxe, or sharp shovel, start loosening the soil under and around the root ball. Rock the shrub back and forth if there’s still a trunk or stump attached. This helps break the suction of the soil and can reveal more roots that need to be cut.
If the root ball is too large to remove in one piece, use a root saw to divide it into smaller sections.
Step 4: Cut Through the Roots
Once exposed, use pruning shears, loppers, or a saw to cut through the thickest roots. You may need to sever roots that reach out several feet in all directions, especially for older or deeply rooted shrubs.
Be patient—cutting through large woody roots can be time-consuming and may require multiple tools.
Step 5: Remove the Root Ball
After the roots are cut and the soil is loose, lift the root ball from the ground. Depending on its size, you might need a helper, a pry bar, or a winch for leverage. Place the root ball on a tarp or in a wheelbarrow to move it out of the area.
If it refuses to budge, double-check for any roots that may still be anchoring it down.
Optional Methods for Stubborn Roots
Chemical Root Killers
If physical removal isn’t feasible, consider applying a chemical root killer. These products are typically brushed onto freshly cut stumps and gradually break down the root system over several weeks.
Look for a product that contains glyphosate or triclopyr. Be sure to follow safety instructions carefully and avoid using near desirable plants.
Stump Grinding
For larger shrubs with thick trunks, renting a stump grinder may be the best option. This machine grinds the remaining stump and roots into mulch, which can be raked up or left to decompose naturally.
Note: Stump grinders should be operated with caution. If you’re not experienced with power equipment, hire a professional service.
Natural Decomposition
If you’re not in a rush, you can let the roots decompose naturally by covering the area with mulch, soil, and water. Over time (usually 6-12 months), microbial activity will break down the roots.
You can speed up this process by drilling holes in the stump and filling them with a nitrogen-rich substance like compost or manure.
What to Do After Root Removal
Once the root system has been fully removed, you’ll want to restore the area:
Refill the Hole
Use topsoil or a soil-compost mix to fill in the hole left by the root ball. Pack it down firmly to prevent settling.
Level the Ground
Rake and tamp the soil to match the surrounding landscape.
Replant or Reseed
If you plan to replant, wait a few weeks to allow the soil to settle. Otherwise, spread grass seed or lay sod to restore the lawn.
Inspect for Regrowth
Occasionally, check the area to ensure no shoots or new roots are developing from leftover fragments.
Tips for Easier Root Removal in the Future
Water the ground thoroughly a day before root removal to soften the soil.
Use landscape fabric or mulch around newly planted shrubs to make future removal easier.
Plant with space in mind. Avoid placing shrubs too close to foundations, walkways, or fences.
Regularly trim and prune bushes to prevent excessive root spread.
When to Call a Professional
You may want to hire a professional if:
The shrub has a large or deeply established root system.
You’re concerned about underground utilities or irrigation systems.
You’re removing multiple shrubs at once.
You lack the necessary tools or physical ability to complete the task safely.
