    Can anyone recommend a weed killer they've used successfully on Bindweed please?

    I have problems with Bindweed invading from a neighbouring garden and I'm looking to buy a systemic weed killer that would possibly work. Any help or advice would be greatly appreciated.

    I've used weedkillers containing glyphosate successfully on bindweed, but I'm not very confident it will work well where it is invading from next door. You'll be able to eradicate it for a while, but it will invade again.
    If you do try it, you need to do no digging in the area for at least 6 weeks after application. I used canes for the bindweed to grow up, sprayed, then let the foliage go brown, shrivel and die. At that point, the glyphosate will have reached the roots, which should also die.
    The truth is, some bits of root will survive, so a repeat spraying may be needed.

      As we don't use chemicals in our garden I regularly go on bindweed patrol in order to keep it down.

      If using glyphosate you need to make sure that the spray doesn't get to other plants. If you are able to isolate the bindweed from other plants you can use plastic bottles, with the top and bottom cut off, place over the plant and spray inside the bottle.

          Encourage bindweed to climb up bamboo cane, remove cane, insert bindweed into a freezer bag, spray with glyphosate and tie bag shut.
          Bindweed then gets a good shot of glyphosate and the bag lowers the chances of collateral damage.

            Thanks everyone for all the replies, really appreciate the help. Can anyone recommend a brand please? There are so many and I'd like to get one that's known to work if at all possible.

            At a garden club visit yesterday so many of us were bemoaning the tremendous amount of bindweed in our gardens this year. I have just been out and tried (I use that term lightly) to remove as much as possible from just a small area. I always seem to end up pulling some of the plant that we want up as well.

              It's not so much a brand name nowadays as a case of reading the list of ingredients (tiny print on box or bottle label) to make sure that you're buying Glyphosate concentrate. Avoid the 'ready-to-use' spray guns. They're over-diluted. Also avoid products from manufacturers that have changed the formula to something organic and totally useless but are still selling it in what looks like the original packaging. Round-Up springs to mind, but someone in UK will be able to confirm, perhaps?

                Thanks for the help and advice. Makes a lot of sense. I've always bought the 'ready-to-use' sprays before and they've not been very effective. I'll look out for a concentrated one.

                  Another method is to use, lawn weedkiller. Put it in an old wide neck bottle or jar. Cut the tip off the bindweed, and (wearing gloves) stuff as much of the bindweed in as you can. Leave till you see the leaves are dead. The weedkiller will translocation to the root. Make sure the bottle is well supported so it can't tip over, and make sure no-one or animals can get to it. Dispose of it carefully.

                    Last glyphosate concentrate I bought here in the UK was Gallop 360, seemed to be the best value.

                      Roundup has now become just a brand name for everything from vinegar solution to weak glyphosate. Look for the line in the small print that says "xxx gm/litre of glyphosate" and find a high number!

                        I am lucky to have several farm shops not too far from me so the last Glysophate I bought was a 5 ltr. bottle of neat glysophate so I have to be careful to dilute it and keep it off my skin. It is very effective on anything with green leaves. I use it primarily to kill off brambles.

                          Which Glyphosate brand was that please @Goldenlily26 ? I bought mine online from Agrichem which says dilute using 19ml per litre water. So pretty strong... I need good stuff for brambles - even triclopyr doesn't hit them hard enough!

                          I'm a new gardener and the new joy of having a garden is being tarnished by weeds and encroachment of unwanted plant varieties. For those recommending glyphosate, a couple of questions:

                          (1) If you get it on soil, does it ruin the soil? (Even the most careful and targeted spraying technique will result in some droplets landing in the soil.)

                          (2) If you've successfully used it on either bindweed or bramble, please would you outline your methods. I'm battling both. (Actually, there's also voracious ivy and elderflower attacking along the flanks, too, but one battle at a time.)

                          Thank you.
