Help! Fast growing weeds, difficult to access

Hi,
There is a large bank behind my fence in my back garden which is densely populated with invasive weeds.

Following advice from a gardener last summer I cut the weeds down to approx 6 inches, waited approx 4 weeks, sprayed all weeds with an industrial strength glyphosate based spray, waited a week, and pulled all weeds at the root. The results initially were superb.

However, months later and there was no real improvement. The weeds came back strong. I repeated the above.

Now summer is approaching, week by week the weeds are growing thicker and taller and soon I will have to repeat the above again.

The problem is the bank is extremely steep, I have to weed one handed whilst pulling myself up and down the bank on a rope. It is tiring and dangerous.

Does anybody have any long term solutions to eliminate the weeds? To slow the growth? Oh, and I plan to stop using chemical methods to control the weeds.

I have attached photos showing the area before weeding, after weeding and present state.

Any advice is appreciated, thankyou in advance.

Scott

    Glyphosphate will do the trick.
    I used Rosate36 on a patch of my garden about 30ft x 30ft.
    I sprayed in early April, then again about 3 weeks later and again 3 weeks after that.
    Within a month or so everything was dead and 4 years on, none of the invasive weeks have returned.
    I did 3 sprayings as there was a lot of ivy too - all gone now.
    The main thing is to wait and let the glyphosphate work.
    You pulled everything out before it had worked properly.

    Before



    After


    Now

  • Did you pull the weeds at all I’m between spraying? Or did you wait until after the third spray?

    the ground will always be colonised by something. Call them weeds or whatever. Killing is temporary, there are plenty more where they came from. If Pete hadn't carried on to cultivation, planting and tending he would be back where he started.

    Yes, Glyphosate/Rosate36/Roundup will "do the trick"... and many other nasty tricks as well.

    You are invited to a virtual visit of my garden (in English or in French).
  • Nutcutlet- I don’t plan on planting or cultivating the area at all. Do I just have to accept that regular pulling of the weeds is required? Papi Jo- I don’t want to use any chemicals. Is just pulling with no solution used enough?

    No - don't pull the weeds. Leave them alone completely
    Just let the glyphoshpate work through the plant system. It's taken up via the leaves then works its way around the plant. This takes time.
    If you have no ivy, 2 sprayings will probably be enough, but leave about 3 weeks between them, then leave everything until it's all dead - just give it time to work.

    You could cover the area with weed control fabric but it wouldn't look very attractive. Alternatively plant something that will out compete the weeds.

    How are you going to stop the bare soil of the bank from eroding away once all the plants are dead?  The weed roots are doing this job for you at present, so if you kill them you'll need to replace them with some other plants or the soil will be washed away down into the rest of your garden.
    This is how to use glyphosate:
    1) wait until weeds are growing strongly
    2) spray them
    3) Wait 5 to 6 weeks before pulling them

    There is not a lot of soil on the bank. The bank mostly comprises of rock, like a bedrock, I think it was installed to support the bank to protect the garden when the house was built in 2000. The weeds grow from inbetween the rock. I could in theory, scrape everything off and be left with the bare rock. The problem is the tricky access. I’d rather not have to constantly maintain it, although it seems I have no other option! Thanks.

    What are your neighbours either side doing with their plots?
    Looks like the right are fencing and the left have started with some wooden steps.

    I think if you don't have the time or inclination to garden at least a layer of weed suppressing membrane once you have tackled the weeds will help to keep it under control.

    It may not look particularly nice but I think it will look tidy and be less work for you.

    If you plan on staying long term you could find money to terrace it.
     
    The whole lot is rather a slope isn't it?!
    Depending on what you want to do or spend, gradually doing shallow terraces with a little set of steps to access, either centrally or side to side zig zag fashion.

    It can be done relatively cheaply with some logs, or if you use freecycle or similar some slabs and similar materials might be found to use.
    It may need something to stabilize it if you remove everything, as the roots will be holding it together somewhat.
