B&Q "Path and Patio" weedkiller
I bought a gallon of B&Q "Path and Patio" weedkiller, which is sprayed onto
each weed. I assumed that what I was buying would be the same substance as Pathclear, except with the B&Q brand name, at a slightly lower price. I've never used Pathclear so I cannot compare the two products. However, I was dismayed at how almost totally ineffective the B&Q stuff was. I copiously sprayed a lot of weeds on a dry day. A week later, all the weeds are still alive! Is Pathclear any better? TIA Al |

Is there a recommended outdoor temperature for it to be effective? Janet I have no experience of the B&Q product, but some general principles .... AFAIK, most weedkillers are not effective below 10-12C. Plus the foliar (systemic) types need the weed to be actively growing - it can be green but not that active at this time of year and so it won't suck the weedkiller in through the leaves as well as when it's less sleepy. I think the residual types like Pathclear work on existing growth in the same way as glyphosate based ones but with the added barrier effect to stop new weeds growing for a while (or more appropriately slow that growth down a bit!). So I'd guess that the same minimum temperature/active growth requirements would apply to what's already there. I don't think of using any weedkiller until at least mid March and I don't use any residual type at all.

Thanks for your helpful feedback. I will follow your advice and try again in March. The B&Q stuff claims to leave no residue in the soil. Al I've checked the B&Q web site and what it calls its Path and Patio product is totally different to Pathclear (which isn't glyophosate based). The B&Q one is simply ready-diluted glyphosate so will only kill what's already growing. Pathclear, on the other hand, is supposed to (I say supposed to because anyone I've ever spoken to says it doesn't really) leave a barrier to stop anything sprouting later from seed. FWIW you will usually save money by buying Glyphosate concentrate (Bayer have both liquid and granular versions for example) rather than ready-diluted versions. It's the same principle as the price of car screen wash concentrate compared to a gallon of ready mixed stuff. Remember that glyphosate works by getting right through the plant down to the roots and killing those as well. This won't happen overnight so you need to allow time for the weeds to die. You can speed things up a bit by spraying in the morning of what will be a sunny, dry day. And don't be too hasty removing wilting growth - the weedkiller will still be working its way down and you don't want to cut it off before it gets there.

Cheers, Jake ======================================= Urgling happily from the dryer end of Swansea Bay where the four seasons are salt,pepper,mustard and vinegar. Can I put a pennys worth here. At this time of year most weeds will have seeds on them if they have not already blown off(to grow elsewhere), so it is important to remove them if you can before treating them. As far as I am aware weedkillers only kill the weed, not the seed. So when the weeds regrow from their seed it is only too easy to hoe the young things where and when they show their ugly mugs, and keep on doing it. Of course if you have a really big garden it can be a big problem. What I am getting at is don't let them seed again, or at least prevent them. See young weeds, hoe them out. Baz |

Baz- Hide quoted text - - Show quoted text - What you must remember, they work on GROWING plants, not plants that have grown and are now dormant. In good growing conditions it can be a couple of weeks before you see any efects from spraying, at ths time of year it could be 4 or 5 weeks. |
I usually keep my paths, drive and patios clear of moss and weeds with my "industrial strength" Karcher. I find using it rather therapeutic. Usually twice a year.
However, an elderly neighbour now sadly departed, managed to achieve the same effect on his, with a weak solution of cheap bleach, applied fortnightly with a bog-standard 5ltr garden pressure sprayer. |
