    Best weedkiller for driveway/patio

    Best weedkiller for driveway/patio 25th May 19 at 10:55 PM
    It's sending me nuts having to continually clear up weeds growing between the patio slabs (18") and driveway (herringbone pattern bricks).

    The main problem seems to be the roots(90% of the time get left behind when doing it by hand (plus the skinned knuckles). I've tried pressure washing the cracks and then re-sanding but they just grow back in a few weeks

    Is there an easier way around this or decent weedkiller product people can recommend.

    You want to buy a product that will persist in the soil/sand beneath the cracks and poison anything that tries to grow there....and so do millions of other people

    Governments have decided to ban substances that persist in soil and work by poisoning it. This is because millions of people spreading poisons that end up in water supplies cause problems for wildlife and producing safe drinking water. The last chemical that worked by poisoning soil was sodium chlorate, which was withdrawn in 2011.

    So...your basic choice for weedkiller is restricted to a product called glyphosate, which breaks down into non-persistent chemicals as soon as it hits the ground.Sometimes, it has extra additives in branded products, but its action is the same; it prevents plants it touches making food, (photosynthesis) so they die in about 3 weeks. Obviously, this isn't great for people who want instant results and protection from further seed germination.

    People will be along with various home remedies shortly, but ever since people have had paved areas there have been weeds growing between the bricks/slabs etc. I used to have a block paved drive and I remember digging out the grot about twice a year, even when sodium chlorate existed. It will be much the same for white vinegar, rock salt or any of the other contaminants people use; they wash away, ultimately into rivers.

    In short, it's a maintenance job that comes with the territory.

    Have you tried a weed burner? I am not saying they are the ultimate solution but they are very easy to use and do give you the satisfaction of an instant result.

    There's a large version called the Sheen Flame Gun that runs on paraffin, but it needs a fair amount of faffing-about preparation, as you'll see if you Google a You Tube video of it.

    Not sure on the effect overall on the roots but I use boiling water to get rid of unwanted weeds / grass in our path

    Get a 6 5ltr sprayer from wilko

    Get the reduced(75% off min) price stuff at end of season from anywhere.
    (or the strong stuff from other sources)

    Spray once a week or as new stuff appears
    (dilute less to be more effective)

    Little and often works on the rooted stuff even hard like brambles.
    New seedlings get them early

    Regular cleaning helps to stop new seeds and nutrition(dirt) get into the cracks.

    Just one of the trade names, which people pay more for than, say, Rosate, one of the commoner internet brands.

    Pathclear, mentioned above, has an added ingredient, which is claimed to inhibit re-growth for 'up to three months.' Pity about the weasel words. You'd have to see if this worked out more/less expensive over time.

    Roundup, Resolve, Pathclear v Glyphosate is the equivalent of Neurofen v Ibuprofen. There aren't lots of weedkiller manufacturers. One factory, many brands.

    I bought a generic weedkiller from Aldi, a huge bottle of concentrate for about 4, the main ingredient is glyphosate.

    The equivalent concentrate of Roundup would be 5x the price.

    Those adverts cost money.

    Thanks for the suggestions everyone, I might try a burner just to have the satisfaction of seeing them burn and then follow up with a generic weedkiller.

    Nice to learn about generic weedkiller, I knew about neurofen vs. ibroprufen but didn't know this.

    If the burning immediately preceded the spraying, there would be no effect, because weedkillers are designed to work on living tissue, as in my original post.

    The weed killer is not a permanent solution as no matter how many times you use it they just keep re seeding. You can kill them for a few weeks but life will find a way.


    Try scraping out the cracks and use a kiln dries sand with cement in a 6 to 1 ratio to fill the gaps so they have nothing to seed into.
    denying them any where to grow through is really the only way.

    If, like me, you kill anything that you plant, try sowing grass seed on your driveway.

    Logically, your seed will not grow and maybe it'll scare the other seeds into giving up. :-)
