Weed killer for lawns

Hi all

just wanted to know what other people recommend for treating weeds in lawns.


I currently use Pistol on driveways or roundup 460 and a grandualted sportsmaster weed and feed on lawns with a broadcast spreader.


I have a factory to sort out with various weeds in the grass all around a foot high or so and only limited access to water hence thinking of using a spray instead of granules

    Weeds in grass at that height will be very difficult to control as they are ''out of spec' for most sprays. Really need cutting back, then treat regrowth, but coming into this time of year, you may be running out of time for active regrowth.

    Need to know what weeds they are in order to advise regarding possible treatments as what kills one weed, won't touch another.....

  • My plan is to strim the site then treat with weed killer next week

    mostly broadleaf weeds

    As Adam has said there isn't a selective product that kills all weeds, I mostly use depitox and praxys in that order but some clover sometimes still remains and if the plants you strim down dont have a lot of leaf left it does not matter what you spray with as it wont take enough of product in to kill it.

  • I doub tyou'll get enough leaf growing back in a week to do an effective treatment. I'd schedule it for May 2020.

    I use depitox it is very effective and also cheap which is a bonus

  • PRO Supplier

    If you strim the grass down to about 6 inches (15cm) then the majority of low growing weeds will be unaffected and can be sprayed soon afterwards - but you'll need to rake then spray or the cut grass will cover all the  weeds! Any tall weeds will need 2-3 weeks for fresh leaf before spraying as Dan said...If you want to send me photos of the site and particular weeds I can advise the best option or combination of products...
