    "You NEED a specialist to remove the knotweed as they need a licence to remove it from ANY property or land. Make sure they are registered as if someone removes it and doesn't have a licence to do so then YOU would also be fined too along with the company that removed it. Knotweed is an invasive species and requires specialist and controlled removal and cutting, the roots of the plant go down over 6 feet deep and spread out so is very hard to kill completely, it spreads fast and wildly... Good luck"

    But you can get some one to weed spray the Area and this will be over a three year period And if you can, three times a year over the three Years. I can come and look for you if you need it.

    "Good afternoon
    Unfortunately you will need to get hold of a specialist to first of all identify it as Japanese Knotweed and then treat it accordingly.
    This plant can be harmful, hence the need for a specialist, and the area will need to be cordoned off and only when they return to sign off your garden as knotweed free will you be allowed to carry out garden maintenance, certainly in the area where knotweed has been identified.

    Hope this helps"

    "Depending on how deep you would have to go & also how much you had, I would suggest hiring a digger if you want to remove it completely from your garden or getting a specialist to help with that!"

    To make sure you really have it check some photos on internet, looking for photo of the seedlings too. When the JKW is small one doesn't recognize it at first sight very easily.

    To remove it you need a specialist because the disposal of it needs to comply with specific rules. Some specialized companies are available to do the first survey to confirm if it's really JKW or not free of charge."

    "If the knotweed is tall, cut to ground level, then spray the regrowth while quite small. Don't let it grow to large. Use Roundup, may need several applications."

    "Yes you need a specialist, it's not cheap to remove because they need to dig down around 6 foot further than the last piece of root they find.
    Please do not use anyone other than a specialist."
