Removing Thick Established Ivy | Tree Masters Herts

Home › Advice Centre › Ivy Removal

Established ivy has a woody stem at the base that can be as thick as an arm, a mass of adhesive rootlets holding it to whatever it is climbing, and a great deal more material in it than is apparent from the ground. It is not pulled off. It is taken down in a sequence.

The Method

Sever at the base. The stems are cut through low down and a section of perhaps 10 to 15 centimetres removed, so the top growth cannot simply bridge the cut and reconnect
Leave it to die back. Several weeks, ideally longer. The foliage dries, the rootlets lose their grip, and the whole mass becomes lighter and far easier to take off
Clear it, working downward. Dead ivy comes away in sheets. Working from the top down means what is released falls clear rather than pulling the section below it off with the wall attached
Clean off the residue. Rootlets and the fine brown fuzz they leave behind are brushed off. Some staining on brick usually remains and weathers over a season or two
Grub out the root crown. The base is dug out where it can be reached, because a cut stem left in the ground will regrow

Why the Waiting Matters

Pulling live ivy off a wall is the single most common way to turn a cosmetic problem into a repair bill. The rootlets are gripping hard, and a live stem pulled downward takes mortar, render, paint and sometimes the face of the brick with it. Severing first, waiting, then clearing does considerably less damage — and less work.

The trade-off is calendar time rather than labour. It is two visits instead of one, several weeks apart. Where somebody wants it gone in a single day, that is possible, but it should be a decision made knowing what the wall will look like afterwards.

The Root Crown

The base of an old ivy is a dense woody crown, often wider than the stems suggest and frequently hidden under a fence line, behind a wall or in a border. Cutting the stem kills what is above it; it does not kill the crown, which will send up new growth.

Where the crown can be dug out, it is. Where it cannot — under a path, against a footing, on a neighbour's side of a boundary — the honest position is that regrowth will need cutting back for a season or two until it exhausts itself, and we will say so rather than imply otherwise.

By What It Is Growing On

Sound modern brickwork — straightforward. Sever, wait, clear, brush off
Old lime-mortared brick or stone — the slowest and most careful version. Never pulled; cleared only once thoroughly dead, and some repointing afterwards should be expected rather than treated as a surprise
Render and painted walls — assume the finish will need making good. Severing and full die-back reduces how much
Fences and sheds — often the fence is being held together by the ivy, which becomes apparent the moment it is off. Worth being ready for
Roof edges, fascias and gutters — done from a ladder or tower rather than by pulling from below, and this is where most of the genuinely useful work is

What Not to Do

Do not use a pressure washer on it. It drives water into every joint it has opened
Do not burn it off. Obvious, and it still happens
Do not strim the base and leave the rest. Dead ivy hanging on a wall for years looks worse than live ivy and still traps moisture
