    First on the list is Japanese knotweed. An infamous weed among home buying and selling circles, it could seriously damage the foundations of your property.

    Aaditya Bhatta, editor and founder of Plantscraze, explains that, if left to its own devices, “Japanese knotweed’s massive root system uses up weaknesses in building foundations and connecting drainage systems, and causes progressive damage, resulting in a defective structure over a long period of time”. period of time.’

    “Japanese knotweed poses a high risk to foundations, sidewalks and gardens because its fast-growing root system can cause costly damage,” she continues. Naturally, this can be an extremely unattractive prospect for potential buyers.

    Unfortunately, it is also quite difficult to remove. Experts suggest it’s infinitely better to call the experts – before people start visiting.

    2. Hogweed

    While this one may look like a bouquet of pretty white flowers, it’s deceptive – because it’s actually just as bad for your home as its rather terrifying name might suggest.

    Giant hogweed spreads quickly, but it does not cause structural damage to your home. In fact, it can cause severe skin irritations instead. It is also difficult to remove and therefore expensive to dispose of (going to professionals can cost up to £15,000).

    Claudia de Yong, landscape consultant and gardener, explains: “It is not easy to eradicate it simply by cutting it down. It is a very hardy plant and should be dug up with its roots attached, leaving no part of the plant in the ground.

    This, and its danger to your skin, can absolutely put off potential buyers, who may be less inclined to buy your property until it’s gone, lest they have to shell out for it themselves. move.

    3. Poplars

    Large trees such as poplars (and willows or oaks) near your home can also be detrimental to the sale. Indeed, their roots can extend up to 40 meters, potentially disrupting the structure of the building.

    De Yong explained, “Some tree roots have the potential to penetrate under foundations, lift paving, block drains and cause serious subsidence or structural cracks. Not all mature trees cause structural damage if planted near buildings, but it can happen.

    Bradley McKenzie, a Stokemont property surveyor, clarified: “Their age, soil type, location and depth are all important in deciding if your tree is a problem. If so, the repair could cost you between £5,000 and £25,000.

    It’s no wonder, then, that they can risk the overall value of your home.

    4. Himalayan Balm

    Himalyan Balsam can look lovely, with striking purple flowers. But if you find this plant in your garden, it’s probably best to remove it as soon as possible.

    Its potential damage to nearby ecological systems makes its presence risky. “Himalayan balsam is another highly competitive, non-native species that enters gardens and shades our native plants,” De Yong said.

    “It is illegal to plant it and let it grow wild. Although its nectar-rich flowers attract pollinating insects, it will deter them from visiting native species. Due to its rapid growth, it can also block waterways and increase the risk of flooding.

    McKenzie explains: “Its significant ecological impact on nature and associated laws are not favored by buyers. It is therefore recommended to control or eradicate this plant.

    Fortunately, however, it is easier to remove than the plants above, with De Yong suggesting that pulling and cutting the plant by hand before it sets seed is a good first step.

    5. Ivy

    Yes, this climbing plant might look perfect, especially when it’s in an old English country house. But, if you have the wrong type, Ivy could create cracks in your structure, allowing moisture to seep through.

    “While ivy can improve the appearance of a home, its strong attachment to walls may worry some homeowners, as it can damage wall surfaces or block drains and gutters,” says Bhatta. “To avoid structural damage to the house, large ivy plants attached to the walls should be removed.”

    She suggests using clippers to prune Ivy to the ground first. “If you have ivy on your walls, they will dry out when cut from below. In order to properly dispose of leftover vines, remove them after they dry out.
