Japanese knotweed
Households are being told to take special measures when disposing of an invasive weed.
Japanese Knotweed can grow up to 20cm a day and overrun gardens and verges.
Waltham Forest council has told residents they must have an arrangement with a licensed landfill site for deep burial, rather than use the brown bins for garden waste.
Japanese Knotweed has a hollow stem, spade shaped leaves and a zig-zag pattern along the stem.
