One thing in your garden that knocks £75,000 off your house price

Small tweaks to homes and gardens can boost property value, as we know. But experts have issued a warning about an invasive plant that could potentially devalue your home.

Japanese knotweed is a homeowner’s nightmare, capable of growing up to three metres tall and being notoriously difficult to eradicate, though failure to do so could result in a 20 percent decrease in property value.

With the average UK property price standing at £373,493 this month, according to recent data from Rightmove, a 20 per cent drop could equate to nearly £75,000 off the selling price, reports the Express.

Bradley Mackenzie from Stokemont advised: “If you spot Japanese knotweed in your garden it is really important to take immediate action before it’s too late. We would highly recommend you seek professional help when removing them as they re-establish easily from even the smallest remains.”

While homeowners can attempt to remove the weed themselves using a potent herbicide like Glyphosate, it must be done correctly.

The destructive plant can spread, damaging pipework, drains and weakening building foundations.

Often flagged as a defect in homebuyer reports, the presence of knotweed could deter potential buyers, causing them to withdraw from a sale.

However, there are measures homeowners can take to convince buyers to part with their money, despite the presence of the plant.

This includes complimentary tasks like lawn mowing, which can “increase the attractiveness” of the property.

Keeping your lawn lush and green through regular mowing, watering, and fertilising creates a stellar first impression.

A healthy, vibrant lawn can suggest to potential buyers that the property is well-cared-for, potentially boosting its overall appeal and value by around two to three per cent.
