    I appreciate that many people don't like using any weedkillers and recommend digging ivy out by the roots. Believe me I would if I could. The problem is that the ivy is growing between a chainlink fence at the bottom of my garden and a wall build years ago by the people in the property behind me. There is no way to remove either the fence or the wall to gain access. The bottom of the garden is being taken over by ivy and I desperately need to find a way to eradicate it. If anybody knows a way other than weedkiller I'm happy to hear it, but main request is for a weedkiller that will work if simply sprayed on the leaves. I'm happy to do multiple applications.

    Glyphosate works, I've used it on ivy around here.
    You need the stronger stuff bought online rather than anything in a garden centre.
    Two applications, second one on any regrowth.

    Thanks @pete I'll give that a try. I have glyphosate which I purchased on line. When you used it how long did it take for any results to show?

    It's not fast, probably about a month,I'd hit it with some now, but maybe next year for the second application.

    Trouble ATM is it's very dry so growth and uptake is lessened.
    Maybe hang on and hope for some rain.

    Thanks for the suggestions. It makes sense to wait for some rain to encourage new growth and uptake.

    Add a little washing up liquid to the Roundup mixture, it makes the stuff stick to the leaves. Ivy leaves are waxy and the Roundup often runs off instead of soaking in.

    @Palustris can you be a little more specific about the amount of washing up liquid for a 3 litre sprayer? Just a few drops, or a decent squirt?:smile:

    I agree with @pete and have used glyphosate to clear an area about 35ft x 35ft of ivy, nettles, brambles etc at the end of my garden.
    The ivy was best part of 2ft thick on parts of the fence.
    It was an unused part at the end of my garden that I'd not touched in about 15yrs.
    When I retired, I wanted a nice greenhouse, veg beds etc so I cleared it all.

    I used glyphosate 360 - the strongest form available to the public afaik.
    To use detergent as a wetting agent only a tiny amount is needed - around 5 drops per 5 litres is all that's needed.
    It did need 3 sprays on some parts of the area about 3 weeks apart.Most of everything was killed after the first spray.
    After about 8 weeks there was no sign of green anywhere and 8 years on, the ivy has never grown back.
    I also got a new fence as after I removed the ivy, the remains of the old one collapsed and the home owners behind me replaced it :)

      I used to use washing up liquid but then I noticed the mixture was actually a soap like on its own, so I stopped.
      I would have thought the manufacturers would actually put a wetting agent in the mix anyway.
      But I suppose it does no harm.

      I seem to remember years ago SBK had in the instructions to mix with diesel for rotting tree stumps, not sure they mention it anymore.

      As said, you only need a couple of drops of liquid soap, less than you would use for a bowl of washing up!

      Thanks again for all the helpful advice. I'll try after a decent rainfall, and report back on results.
