How Deep Are Ivy Roots? What We Found After Removing Ivy From a Brick Wall
If you’ve ever pulled ivy off a wall and thought, “Surely the roots go down forever,” you’re not alone.
In reality, on most domestic jobs we see, ivy roots are usually quite shallow — but they can spread a long way sideways. That “wide and shallow” growth habit is exactly why ivy is so good at coming back if the base isn’t handled properly.
This job is a perfect example. From the outside it looked like a fairly small ivy issue around the base of a brick wall — but once we opened the soil up, the root system was much larger than expected, with thick runners spreading out under the surface.
In this post we’ll show you what ivy roots typically look like once exposed (using photos from a recent job), explain how deep ivy roots normally go, and what that means for preventing regrowth.
The quick answer — are ivy roots deep?
Most ivy roots are not deep like a tree’s tap root.
They tend to sit near the surface and spread outwards through the top layer of soil. On many jobs, the main roots we remove are shallow enough to expose with careful digging around the base.
What surprises most homeowners isn’t the depth — it’s the spread. Ivy will travel along easy pathways (loose soil, borders, under turf edges, along walls) and send out multiple runners.
What ivy “roots” are we actually talking about?
Ivy has two types of growth that people often mix up:
1) Underground roots (the ones that feed the plant)
These are in the soil. They supply water and nutrients and are responsible for regrowth if they’re left behind.
2) Clinging roots / tendrils on walls (the ones that stick)
These are above ground. They act like anchors, helping ivy grip brick, render, timber, and fences — but they’re not the main feeding root system.

Real job example — a “small” ivy issue with a surprisingly large root system
On this job, ivy had taken over part of a brick wall and the base area. From a distance, it didn’t look like a major problem — just a moderate patch of ivy.
But once we cleared the growth and started digging, we found:
- the main roots were close to the surface
- the system spread outwards rather than going straight down
- there were multiple thick runners feeding into a larger root mass
This is common with ivy. The visible growth doesn’t always reflect what’s happening underground. You can have a relatively small amount of ivy showing above ground, but a well-established network of roots and runners below the surface.
What that means for homeowners
If you only remove what’s visible on the wall but leave the base and shallow root runners intact, the plant often has enough stored energy to push up fresh shoots later.
Why ivy doesn’t usually need deep roots
Ivy is very efficient at surviving because:
- it can thrive in shade and use moisture held in surface soil
- it spreads laterally and finds multiple feeding points
- it climbs walls for light rather than relying on deep water access
So instead of digging deep, the plant often wins by spreading wide.
How to check how far ivy roots go (simple homeowner method)
If you’re investigating ivy at the base of a wall, you can usually learn a lot with a small amount of digging:
Step-by-step
- Find the main stem(s) where ivy meets the ground
- Pull back loose soil carefully with a hand trowel
- Look for thick runners heading left/right under the surface
- Follow them gently — you’ll often find they run sideways just under turf or border soil
If you start finding thick, woody runners disappearing under patios, fences, or into established planting beds, that’s when a job can become more involved.
How to stop ivy growing back (without turning your garden into a crater)
You don’t normally need to excavate half the garden. The goal is to remove or properly deal with the parts most likely to regrow.
Focus on
the main root crown / stump at the base
the thick shallow runners close to the wall
any secondary stems that feed into the main base area
Then monitor
Even after a thorough removal, keep an eye on the base area for a few months. If shoots appear, deal with them quickly before they re-establish.
What about removing ivy from brickwork?
We won’t go deep into “methods debates” here, but the key practical point is this:
Walls are damaged more by force than by ivy itself.
The safest approach is always the one that avoids sudden tearing and lever-like pulling on weak mortar.
A few sensible tips
- work in small sections
- keep tension controlled and shallow (peel away rather than yank out)
- once growth is removed, address the remaining wall residue/tendrils carefully

FAQ — ivy roots and regrowth
Do ivy roots damage foundations?
Most of the time, ivy roots are surface-level and don’t behave like aggressive foundation-seeking tree roots. The bigger risk is ivy exploiting existing weaknesses (cracks, gaps, loose pointing) and holding moisture against a structure.
Will ivy grow back if I remove the visible plant?
It can. If the root crown or shallow runners remain, ivy may regrow from the base area.
How wide can ivy roots spread?
Often wider than people expect. Ivy commonly spreads laterally through the topsoil, especially where soil is loose and shaded.
Is ivy removal messy?
Yes — particularly once you start exposing the shallow runners and soil around the base. The underground part is often the most surprising stage because the root network can be much bigger than it looks from above.
