I’m a gardening expert – is Japanese knotweed illegal in your garden and what to do if you have it
WE’RE all aware that weeds are a pesky addition to any garden, due to the fact they’re an eyesore and can do plenty of damage to your patio.
But there’s a specific type you should be on the lookout for - otherwise, you could have a nightmare job, and a hefty fine, on your hands.
Japanese Knotweed, or Reynoutria Japonica, is a rapidly spreading weed that grows into bamboo-like stems, potentially reaching as high as 7ft.
This perennial weed is a well-known nuisance, not only because they suppress all other plant growth, but also as they're incredibly difficult to get rid of.
Eradication requires the help of a professional, due to the fact it’s hard to remove by hand or with chemicals, thanks to its creeping roots.
And leaving even the tiniest amount in your soil means there’s a chance it’ll grow back next Spring.
