Grass in a hedge

We have a customer with a mixed hedge consisting of blackthorn, hawthorn, pyracantha and a few roses etc. The site had previously been let go and we have got it back to a good standard... Except for this hedge!The grass has pretty much grown all the way through the hedge and comes out the top as the hedge is only about a meter high.Any suggestions on how to get rid of the grass apart from hours of thorny hand weeding?Cheers, Darren

    Is there a gap at the bottom at all, where you could CAREFULLY spray the offending weeds?

  • Selective herbicide?

    There are some gaps in places. It is mainly grass growing, but I was worried about getting it on the hedge. What selective herbicide would you recommend guys?

    If you can't carefully spray RUP or use a Weed Stick before the hedge leafs, what about something like Kerb grannules et al  (although you've probably just missed the window of opportunity?). Won't kill on contact so you may still need to do some pulling anyway of subseqent dead stuff but should stop it reoccuring.

    [Edit] legally you've got until end of Feb to apply Kerb etc ;)

    • Hi Gary,

      This is a common misconception with Kerb!!

      The date restrictions only apply to certain arable and fruit crops, but not to amenity vegetation and hedges.

      Kerb label

      Not trying to nit pick! Just wanted you to be aware!

         Never used Kerb Liquid, but Kerb Grannules use states:

        "For Trees & Ornamental shrubs:

        Soil and weather conditions:
        Kerb Granules require moisture for root uptake. Best residual action is obtained in moist, cold soils. Kerb Granules can be applied in all weather conditions. Application on top of snow and to severely frozen ground is not recommended where run-off is likely to occur.

        When Best  to apply:
        For best control cold, moist  conditions are required after application. In southern counties of England and Wales, and on peaty gleys and peat soils with a depth of organic matter greater than 10 cm (4 in), best control is usually achieved with application from 1 October, but no later than the end of January. In other areas, and on mineral soils, similar levels of control may be achieved with applications from 1 October, but no later than the end of February. Local conditions (e.g. altitude, north-facing slopes, previous weather) may affect these timings.Should warm, dry conditions prevail after application, weed control may be reduced
        "

        If I've misread the label, then I have misread the label, but the way it structured has always led me to believe this to be the case.

        Has control been reduced then ?
         

  • Hi Darren,

    If you are quick, you still have time to apply Kerb, either as granules or liquid and you can also mix this with Flexidor to gain extra control over a wider range of weeds. There is not actually any last date of application for Kerb to hedges, but it does want to be applied when soil temperatures are below 8 degrees. It would depend on how long your hedge is as to whether you want to go for this option, as the Kerb or its equivalent generic come in a 5L containers.

    Another option would be to wait until a bit later in the Spring and use a graminicide such as Shogun.

    I have included a couple of links below for these products.

    Darren, the other replies are not in strict chronological order, but as has been pointed out, Kerb cannot be applied this late and Flexidor on its own will not control grasses.

    Why not try a weedwiper with glyphosate - it can be pushed along at ground level to avoid the hedge leaves and flatten the grasses - covering them with glyphosate in the process...no overspray or drift and at least its a step up from hand weeding!!
