Selling your home in Sussex? These five garden plants could devalue your property

The survey practice conducted the survey and revealed the estimated cost of removal of each invasive plant.

Stokemont real estate surveyor Bradley McKenzie has also shared some tips on spotting them.

1: Japanese knotweed (UK search volume 90.5,000, estimated removal cost up to £15,000).

Japanese Knotweed is one of the plants that could devalue your home if you are trying to sell in Sussex

This plant has bamboo-like red shoots and shovel-shaped leaves and can grow up to ten feet tall in spring and summer.

Its roots can also reach up to 20 meters underground, according to Stokemont, which could “destructure” pipes and drains and weaken building foundations or pavement.

Japanese knotweed is listed by RICS Homebuyer Reports as a property defect, with the potential to reduce a property’s price by five to 15 percent.

Bradley said: “We would strongly recommend that you seek professional help if you are removing them as they are easily restored from even the smallest remnants.

“If you prefer to do it yourself, pesticides would be the most effective way to kill these zombie-like plants.”

2: Ivy (UK search volume 33.1k, estimated removal cost up to £1k)

Strong on climbing walls, ivy can penetrate wall cracks, damage mortar, and cause moisture and leaks.

Bradley said: “Unlike giant hogweed, English ivy could be removed with bare hands by gently peeling it off the wall.

“You can also kill them by cutting off their roots and letting them dry out.”

3: Giant Bear Claw (UK search volume 22.2k, estimated removal cost up to £15k)

Giant hogweed is invasive, spreads quickly and is easier to spot in June and July.

It looks like cow parsley but has thick green stems with purple spots and white flowers in a round umbrella shape.

Bradley said: “Widely distributed across the UK, especially around rivers and ponds, its sap is phototoxic and can cause severe skin burns or scarring when exposed to sunlight.

“While there is no direct damage to the property, buyers can still refuse to pay a higher price, if any, as the removal costs are high – up to £15,000.”

4: Poplars, willows and oaks (UK search volume 14.8KB, estimated removal cost up to £3,000)

Large trees like cottonwood, willow, and oak can be dangerous if they grow near a property.

The root systems of these trees are shallow and fast-growing and can spread up to 40 meters, absorbing 1,000 liters of water and nutrients from the soil.

Bradley said: “If they grow too close to your property, they could introduce further risks of cracking in foundations, subsidence and other structural defects that could potentially cost you £5,000 to £25,000 to repair.”

5: Himalayan Balm (UK search volume 12.1k, estimated removal cost up to £2k)

This Himalayan plant was brought to Britain in 1839 and grows up to three meters tall.

It has pink flowers in summer and early fall and can spread seeds over 800 meters or through rivers.

This can potentially kill other plants and reduce biodiversity by stealing light, nutrients, or water.
