The Royal Horticultural Society (RHS) has outlined three expert methods for permanently removing invasive ivy from gardens. English ivy, while beneficial for wildlife and shade gardens, can quickly spiral out of control, damaging fencing, walls, and even causing structural problems by working into cracks and joints.
When to Remove Ivy
According to the RHS: "If ivy isn't causing any damage, it is often best to leave it in place. However, if you have ivy growing where it isn't wanted, or it is necessary to remove it, there are some options." On buildings, ivy can creep into gutters, windows, and roofing, complicating regular maintenance. Many homeowners choose to remove it entirely.
Method 1: Trim Stems Routinely
Use secateurs or loppers to cut back ivy growth from guttering, windows, chimneys, and roofs. Depending on the plant's size, this may be required several times annually, though once a year is typically sufficient. For mature plants, exercise caution when cutting back, as it may loosen masonry.
Method 2: Remove Sections of the Plant
This approach is recommended when ivy spans a vast area and full removal is too challenging. The RHS advises: "Start with the outermost stems, which will be most strongly attached to the wall or fence, and use secateurs or loppers to cut and peel stems away. Work slowly and carefully to minimise dislodging loose masonry."
Method 3: Remove All Ivy Stems
For complete removal, the RHS says: "Where you wish to remove ivy entirely, begin by cutting and carefully peeling off the outermost stems. Work steadily inwards towards the larger, central stems." These inner stems are less strongly attached but thicker and woodier, possibly requiring a saw to remove in pieces. After clearing all stems, use a sharp spade to extract the stump along with as many large roots as possible. This will "stop the ivy regrowing." The experts add: "If you can't remove the stump, regularly cut any new growth back to ground level. This will weaken the plant, although it may take a long time to kill it."
Other Invasive Plants
Numerous other garden plants can also cause harm, including Japanese knotweed. This requires professional help, as it can lead to serious problems.
