Knotweed

Hi there I think I have found knot weed at the end of my garden could someone please give me some advise on what to do ?

 

Spray it with a strong dose of glyphosphate.
Mix a little diesel with it too for maximum effect.

Or you can chop it down and put near glyphosphate onto the opening of the stems.

There's no quick fix but you'll be able to keep ontop of it quite easily.

 

I think I have the same thing shoots coming up all over, as fast as I pull one up another appears, the problem is in a nice part of my garden will glyphosphate effect my other plants please ? the area in red is mainly effected.

 

You would need to use it:
a) on a day when rain is not expected (so it doesn't get washed away)
b) when there is no wind (the wind would blow drops of it onto your nearby plants)

My old garden was becoming infested with mares tail. I saved some small water bottles, cut off the bottom, put the spout end over a piece of mares tail and then sprayed it via the open bottom of the bottle. The body of the bottle acted as a barrier from any spray being carried by an unexpected breeze. Thing is, if you use that method, leave the bottle over the plant for a couple of days because if there is any moisture on the inside of the bottle, the moment you lift it off, a drip or a drop could (I say could, not will) land on nearby plants.

Or, you could spray a paintbrush with the glyphosate and paint the leaves of the plant you wish to treat.

Both of the above using this:


Or, you can buy glyphosate in a gel form. The application surface is full of little holes and a button at the bottom of the canister. You pump the button and the gel comes up through the holes and then you simply "paint" the gel on the plants you wish to get rid of.

This is the gel:

 

Break the top off the stems and put neat glyphosate in the hollow stem, cover up with a plastic bag with a rubber band round it.

Burn the bit of stem you cut off, don't lob it in the recycling bin.

 

Or eat it...

Martin, do you have a close up.

Just that it looks a bit like bind weed to me.

 

Hi Pete, that is the effected area ive pulled it all up now but it appears again in a few days the picture was to show were the problem is, I don't want to kill anything in this area only the maybe knot/bind weed,

When some appears again and it will I will post a close up many thanks

 

Hi Pete, this is the stuff.

 

Looks like bind weed Martin, not Knotweed.
Still a pain, but it wont undermine your foundations

 

Many thanks Pete, i will just keep pulling it up I also have a few bulbs in this area I don't want to harm.

 

You could still let it grow a bit and then, when it has lots of leaf, treat it with glyphosate.
The more leaves the plant has to absorb the herbicide the better the effect.

 

Thanks Pete I will do that then .

 

@martin-f , let a length grow, then scrunch and curl into a plastic cup without holes then spray that with round up and leave all to soak in. Will soon die off.
Keep at it! We had a major infestation when we first moved in but after carefully removing as many roots as we could (emptied a whole raised bed) then doing the above its mostly beaten.
