Some ground elder has come through from next door's garden and I have sprayed it with glyphosate solution some days ago.  No reaction so far.  How soon can I expect to see some effect.  I am about to spray another pernicious weed.  I don't know what it is called.  Had never seen it till we moved from Herts. to Bucks.  It has a pink flower if one leaves it that long and long white roots and is spreading everywhere.  Very difficult to get all the root out and it seems to spread that way as well as by other means.

    It can take 2 weeks or a bit more before you see the results depending on the weather.
    If there are weeds that still look OK after 2 weeks, then another blast should do the trick.

    I've not used it on ground elder but I used Rosate36 on an area 30ft x 30ft last year and 3 applications over about 10 weeks killed all the brambles, nettles and after the 3rd blast even killed all the 2ft thick ivy on the back fence, which is very impressive

    Ground elder isn't very susceptible to glyphosate in my experience, and you may need to try digging up the roots as well.  They don't go down a long way, but spread horizontally for ever!  If your soil is light you can completely eradicate ground elder by careful digging.

    If your pink-flowered plant is bindweed (does it twine round other plants?), you definitely can't dig that one out cos its roots go down metres, and break when you pull them.  But it's very susceptible to glyphosate weedkiller.  image

    I am amazed that the Glyphosate weedkiller (aka Roundup) is so widely recommended by members of this forum in many discussions. Are those members sponsored by Monsanto? unaware of the dangers of Glyphosate to the environment? See e.g.

    Papi Jo,

    I think we're all very aware of the evils of glyphosate.. but for some of us, it's a necessary evil used as a last resort (and in moderation).  I only spray bindweed and couch grass, because any amount of digging in my garden is not going to eradicate it.  I did years of hand pulling, mulching, etc.. but it just got worse and worse.  I still battle it, but the glyphosate allows me to enjoy gardening again.  I don't spray my lawn (which is where the bindweed and couch grass are traveling from into my raised beds).. and everything else about my garden is organic.  BUT, for the Roundup.  I practice no dig, yet I found in my battle with the couch grass, in particular, I end up digging over the entire bed in search for roots.  Destroying all the goodness of no-dig (and severing countless worms in the processimage).  So I spray here and there, typically several weeks before planting my veg garden.  Once things are up and growing, then I do the weeding by hand.  

    And if a bit of Roundup here and there allows Bouleversee to enjoy the garden, I don't hold it against them, because I understand.  Same as I understand your point about the harm to the environment (but not about sponsorship).  

    Use of glyphosate on a mass scale by agriculture is another story..

    Ha... I have marestail too.. that's nothing compared to Goat Head Weed.  I live in Utah, USA.. and keep finding this guy in the grass.


    Looks pretty enough.. and contrasts nicely with the blooming bindweed growing with it.  Expect for the seed heads.


    They are like those medieval devices for injuring horses in battle.  Except it's bare feet and bike tires around our house.


    Nasty things.

    I went from gardening in the clay of Richmond, Surrey to the green sands of Dorking.. and then to the high altitude desert of Utah.  It's been a real learning curve.    image  No slugs and snails in sight.. but plenty of other different issues to deal with.
