    Hi all, I've got a weed problem at the rear of my house, in my bin access alley.
    It seems to grow quite quickly and its definitely spread more this year. I think I chopped it down last year and binned it but didn't seem so much.
    Im hoping somebody can identify and tell me it isn't japanese knotweed.
    Thanks in advance.

      Bit of a mixture, looks like some bamboo in there amongst other things.

        Thats good news. What would be the recommended course of action? Just chop as much as I can away and spray with the strongest stuff I can find? Thanks

        Don't chop it back yet, the more foliage it has the better it absorbs weed killer.
        The bamboo appears to be coming under the fence from other gardens?

        Any chemicals you apply will be transferred to the rest of the plant on the other side of the fence,so something to think about.

        I'd use glyphosate, it will possibly need more than one dose.
        So, treat, then wait for it to work ,,could take a few weeks ,then treat any regrowth.

        If it was mine I would dig it out as it doesn't seem a big area. Then check if the bamboo is coming from next door, and if necessary put in a barrier. Otherwise it will just keep coming back.

          Behind the fence is just a small public pathway that very few people use due to it going nowhere. Thanks for putting my mind to rest of the knotweed. I'll get some glyphosate spray ASAP and cover it all. Cheers all
