UK homeowners are being urged to act fast as invasive is set to thrive in June, thanks to a potent mix of warm and wet weather.
Following after an extended dry spell, experts are warning that Japanese Knotweed, which is one of the UK's most destructive , is now entering a period of "super growth," posing a serious threat to gardens, property structures, and even home sales.
Terry Fisher, a property expert with Sold.co.uk, cautioned that the weather shift has created perfect conditions for rapid growth.
"We've been basking in glorious sunshine, but now the rain has made an epic return," Fisher told . "This combination of wet and warm creates the ideal conditions for Japanese Knotweed to thrive and even go into a super growth phase.
"Homeowners might unearth a beast in their gardens this spring."
Originally introduced to the UK in the 1800s as an ornamental plant, Japanese Knotweed can now grow up to 10cm per day in summer and reach over 2 metres tall.
Its strong root system can penetrate tarmac, concrete, and even building foundations, making it a nightmare for homeowners.
Gardening expert Kendal Platt explained what to look for bamboo-like shoots with hollow, red in spring and green in summer. They also have heart or shield shaped with pointed tips.
If left untreated, Japanese Knotweed can cause thousands of pounds in damage to buildings and patios.
Experts strongly advise against trying to remove it yourself. Mishandling can easily spread the plant further, as even a tiny fragment can regrow.
"Avoid attempting DIY removal," Fisher said. "It requires a multi-pronged approach, often involving herbicides and potentially excavation, depending on the extent of the infestation. This is best left to professionals."
You should Inspect your garden regularly, especially near fences, patios, and outbuildings and hire a certified specialist if you suspect an infestation.
The longer it's left, the harder and more expensive it is to treat.
