The invasive Japanese Knotweed plant is causing problems across the UK, with over 50,000 investigations currently ongoing.
It can grow up to 10cm a day and is capable of pushing through brickwork, paving slabs, drains, sewers and cavity walls – potentially doing great damage to property.
To deal with the continuing spread, there are now fines for people who don’t take action against the weed, along with other plants that can cause a range of issues.
With this in mind, garden experts at Power Sheds have listed the top ‘criminal plants’ that could be growing in your garden and how you can save yourself from a hefty fine.
Jack Sutcliffe, co-founder of Power Sheds, explained: “Once you can identify the most common criminal plants, it’s important to prevent them from spreading as soon as possible. The easiest way to do this is by spraying them with chemicals, digging them out or burning them.”
So, here are the plants to look out for.
5. Curled Dock
Another noxious weed, the curled dock, has distinctive curly leaves and spikes of small yellow flowers. It can spread quickly and is a flexible weed. Fines of up to £2,500 can be given for allowing it to grow on your property. Photo: Canva/Getty Images
6. Rhododendron Ponticum
Growing to considerable heights, the Rhododendron Ponticum is another invasive plant on the list; it will even compete with other plants for a little bit of sunlight! The plant has evergreen leaves and large clusters of pink or purple flowers, and is poisonous to vegetation and wildlife. It is difficult to eradicate once established, making it even more important to avoid growing it, otherwise you could face a £5,000 fine. Photo: Canva/Getty Images
7. Himalayan Balsam
While it can look pretty, don’t be fooled by the Himalayan Balsam! Perhaps one of the quickest to spread, each plant has around 800 seeds that are easily transported by wind, animals, or water, and will grow again. The plant has spikes of showy pink or purple flowers, and fines can go up to £2,500. Photo: Canva/Getty Images
8. Giant Hogweed
This toxic plant is harmful to humans, as its chemicals can cause significant wounds to the skin. While for some, it is just a burning sensation, for others, it can cause permanent scars. This is why giant hogweed is considered illegal and the fines can go up to £5,000. They can be recognised by their large white flowers and towering height. Photo: Canva/Getty Images
