The tube is then filled with the weed killer, which soaks into the wick and he dabs at offending weeds with it, so there is no spray. I really must take a photo of it but I feel sure that your personal handyman could make one for you! It's much the safest way to attack individual weeds in a border, for example. Yes I am sure he could Thanks -- -- http://www.shop.helpforheroes.org.uk/ |

But the dose makes the poison. Holly and ivy seedlings are usually sufficiently waxy to survive application of glyphosate (more mysteriously so are buttercups although they do not at all look well afterwards). Apart from that any green material you touch with glyphosate will potentially doom the plant. Try not to hit anything you don't want to kill. Having said that I would not be worried about using it near or under holly bushes or any other shrubs where I could keep the stems away from the spray. I suspect that since holly seedlings survive application of glyphosate the full grown plant will too but I have never done the experiment. Grass is exquisitely sensitive to it so beware of outline marks left on your lawn by any overspray on boots. Cutting bits off to avoid collateral damage fairly quickly will work as a last resort. Don't spray on a windy day and don't use too fine a spray that will be inclined to drift too far. Many thanks for that! Most welcome! -- -- http://www.shop.helpforheroes.org.uk/ |

I've not found it to be 100% effective against bind weed. It seems to work at the time, but after several weeks or even months new shoots often pop up out of the ground. |

If not what can I use? To kill the ivy that is? Alan The waxy leaves of ivy tend to resist glyphosate, just as the coating on mares tail. I kill ivy by chopping it off about 6 inches above ground (which generally kills what's above the cut as long as there isn't an alternative "food source" higher up for it to root into). Chop mares tail about 2 inches above ground. Then inject glyphosate into the stump using a syringe (purchase one from your local chemist but don't let them fob you off with diabetic needles - they're too narrow and weak to work). Just poke the syringe carefully down into the centre of the stumpy stem, making sure that you DO NOT hold the stem with the other hand! If you need to hold the cut stem steady, use a pair of pliers or something so there's no risk of accidentally injecting yourself.

Not a chance - the wetting agents in commercial glyphosate formulations are the most dangerous part of it (way more vicious than puny washing up liquid). I suspect bruising the leaves first might help. But usually cutting the stuff off at the roots works well enough. -- Regards, Martin Brown |
