I need to kill an invasive plant, I dont know what it is so have posted link to a picture. It grows very fast and can engulf the house if left. https://imageshack.com/i/e9vi4bj Cheers

    Perhaps someone can put this up as a link, please.

    Sounds like it could be japanese knotweed.

    Gardening on the wild, windy west side of Dartmoor.

    Doesn't look like it though.

    If you highlight it and alternate click you get go to http etc.

    I'll see if I can linkify it

    How tall does it get andy?


    Has that done it?

    The picture doesn't look like knotweed to me, but I don't know what it is.

    I dont know what is is, but its not Jap Knot weed.

    It's not a mess, it's a nature reserve.

    It gets as tall as it can, I pulled it down and some went up 25 feet, under the tiles into the loft space and rooted into the gutter. Will grow a foot in a summer day. Doesnt cling like ivy and can be pulled off easily.

    Where do you live andy?

    Does this plant flower?

    Does it have tendrils to cling on with'

    Does it wind itself round other plants or structures?

    Can it support itself or does it always climb, sprawl?

    Southend. Essex.

    Never seen it flower. It doesn't really cling, it just sits over the fence and comes down easy.

    Found a picture of what it looked like in december before I pulled it down from out the window

    Sorry andy, I don't know any plants that start off looking like picture one and end up like picture 2.image

    Looks a bit like basil in picture 1, no idea about pic 2, very strange!

    That looks very eerie growing over the house like that. How long does it take to cover the house? is that years of growing?

  • steephillsteephill Posts: 506

    A couple of suggestions,  Russian vine or clematis Montana. A photo of the offending plant in full growth during summer would help a lot.

  • nutcutletnutcutlet Posts: 24,056

    A summer pic would certainly help. Pic one doesn't look like anything that could achieve that sort of growth. 

  • Orchid LadyOrchid Lady Posts: 5,800

    I don't know any plant that could achieve that growth, I know I'm not an expert but surely it would be well known?

    Wild honeysuckle maybe? although it doesn't look like one.. trying to think of something that grows that much and quickly

  • nutcutletnutcutlet Posts: 24,056

    I can think of a few things that could do the height but none of them look the first pic at any stage of their life.

    are you sure the 2 go together andy? image

    ..I agree with steephill about it being a Russian Vine, although it would have flowered though... on top of that roof I expect... ..possibly an Ash tree too grown up alongside...?....  those green things just look like weeds to me...

    I'm not going to allow it to grow over everything but il let the patch in the corner grow a bit to get a photo of it a bit larger. Trust me its the same plant and in a few days it will be double the size. Theres a bit over next doors fence so hopefully it will start to show leaves

    Pics 1 and 2 must be from different plants - 

    I think Pic 1 is possibly Saponaria officinalis aka Soapwort or Bouncing Betty - grows fast and is invasive but doesn't climb.

    I think Pic 2 is possibly Polygonum baldschuanicum/Fallopia baldschuanica aka Russian Vine/Mile a Minute etc etc etc. 

    Both of which were rampant in this garden when we moved in here - Andykites,  are you my neighbour? image

    Gardening is cheaper than therapy, and you get tomatoes.

    Hopefully not. Doubt the neighbours are happy as theres ivy everywhere too ???? il leave it a week to prove its the same plant, il also ask my mate if its ever flowered as I havent been here long and hes put up with it fir 20 years.
