    I have a gravel driveway and would like to permanently kill everything that
    grows there. I saturated the area with Roundup which killed some of the
    weeds but not all, and after two weeks everything was growing again. I
    sprayed it with Green Thumb Weed and Grass Killer and that also killed only
    some of the weeds. Has anyone had any experience with anything that will
    permanently and totally kill weeds and grass and prevent regrowth for an
    entire season?

    Asphalt or concrete will kill the weeds and prevent their reappearance.

    Its environmentally incorrect but gasoline will kill stuff withing a
    hour. slow regrowth does occur, usually 2 treatments per year do it.
    still cheaper than most vegation killers

    yeah i know i am bad, it works fast and is still pretty cheap

    Yep, but they want $1800 to pave the driveway. That'll buy a lot of weed

    Most weed killers only kil gowing weeds, Seeds are uneffected and will
    sprout when ready

    Roundup will need reapps..

    I use Triox Vegetation killer years ago but it letches away with rain &
    watering...............kills plants "downstream" Ooops!

    Leaches/washes away. Sure does and then into our, or somebody else's, water
    How come, for example, the North American Great Lakes are becoming so
    polluted with chemicals. Chicago water supply here we come!

    Driveways on the usually smaller urban lots are often already paved when you
    buy the house or cost little to do so!
    Coupla thousand maybe!

    So whenever anyone mentions a 'gravel driveway' it envisions a rural area?
    That often means either ground water or deeper drilled wells for domestic

    We have a well that today is unusable (certainly undrinkable) because of
    various neighbours over the years having irresponsibly used pesticide and
    herbicides. Sometimes for no better reason than a few dandelions!

    Ah well; global warming, additional flooding and the increasing number of
    typhoons etc. will take care of all of us. Let alone a few weeds!

    Damn! You beat me to it. <G>

    About 20 years ago I used a Dupont product calaaed Vapam to kill
    everything, including insects, when I wanted to rebuild our front lawn
    "from the ground up". Worked great as I recall.

    I think Dupont sold the product/name to some other company, but it's
    still listed on this page describing non-selective herbicides:

    And new seeds are deposited regularly.

  9. You need to use a vegetation killer not a weed
    killer. You will still probably have to apply it
    at least twice each season.

    Most garden stores and big boxes (Home Depot, Lowes, etc.) sell total
    vegitation killers. These do work pretty well for a single season, but
    they have disadvantages as mentioned by others. They are not
    environmentally friendly, and the chemicals can flow downstream and
    kill other stuff. If there are trees or shrubs near the drive, I would
    be reluctant to use a total vegitation killer for fear of hurting the

    I have found a combination of round-up and preen works pretty well.
    Roundup kills the currently growing stuff, but won't hurt anything
    downstream, because it has to be absorbed through the leaves. Preen
    keeps new germination from happening, but doesn't kill anything that
    currently exists, so again you don't risk damaging existing plants.
    One application probably won't work for the entire season, but two or
    perhaps 3 applications per season should do it. You might be able to
    get away with a first application of both in spring, and then just
    preen in mid-summer.

    Both roundup and preen are less damaging to ground water and the
    environment than a total vegitation killer.

    If you already have a fair number of weeds, you will need to use 2
    applications of round-up, about a week apart. Despite what the bottle
    says, in my experience round-up does not kill everything in one
    application. Round-up works best when things are growing, so it's
    effective in Spring.

    Otho and some others are selling combination chemicals that seem to be
    a combination of round-up and a preen-like substance. I haven't tried
    them (I've just used the two products separtely), but they might be
    worth a try.

    Chiil Stan-

    I mis-typed I "used" Triox Years ago (25); once & it letched, I

    1. RoundUp et al only kill what they contact

    2. New seeds will sprout

    3. There are chemicals which will sterilize the ground but I don't think
    they are available to home owners.

    4. If your driveway gets lots of sun you could cover it with black
    plastic for a few days...that will kill most all including seeds.

    landscape contractors have much stronger effective chemicals, to be
    assured they are used properly....

    homeowners type chemicals are weak versions of what used to be
    effective treatments.

    theres a safe cheap effective treatment, spread rocksalt on the area
    and water it in preferably with hot water.

    ever notice the dead grass near sidewalks treated with salt? just do it
    on your driveway.

    i dump it in my washtub and add hot water a few times a year, espically
    in the spring, my terracota sewer line is bad, this kills the tree
    roots while the trees grow fine.

    safe cheap effective

    i wonder if that would be safe in a septic tank application?

    I would like to pursue this idea. Is it for real? a lot of what i
    read on the
    net looks like: "i had a problem, i put enter-treatment-here, and i
    had it again."
    well, somebody even said they used Round-up which is ineffective on
    so, about this rock salt. have you actually seen the roots? i can use
    it cause it's pretty cheap but i'm very interested in seeing some
    of studies.
    thanks for any help you can give...thehick

    I also have weed problems. OLD cracked asphalt driveway and a long
    one. Surely can't afford to replace it. And I read all the posts
    here. NONE of it works! Roundup is the closest to a working product
    but not against crabgrass. NOTHING kills that. Tried black plastic on
    a small veggie plot. Left it there for SIX MONTHS! Yea right. Well
    when I picked it up, the crabgrass that was under it was all yellow.
    And in a week it sprung right back to life!!!
    Tried vinigar, salt, even some of the strong stuff my husband got while
    delivering it to farmers. I dont' want to use any of it. I have a
    well and don't want to hurt the environment even if I didn't have a
    well. This stuff doesn't just go away. It all goes somewhere! I keep
    roundup on hand for the occasional large weed that got past me in
    spring. But that's all.

    It's not the prettiest way but affordable. I make cement stepping
    stones to sell at craft shows. The extra cement poured into the cracks
    will STOP the problem. First dig out all the weeds and as much dirt as
    you can. Then when I clean the bucket anyway, I make sure I have extra
    and dump the extra cement in the cracks. Again not pretty but no
    weeds! I have even done this by pouring in the dry cement mix into the
    cracks and lightly spraying it with a hose. It works.

    Don't know what to tell the poster about gravel. Ever try racking it
    on occasion? I have a simple weeding tool for my garden works on the
    principal that it slices the young weeds at the base before they get
    too big. Works well if you go at it on a regular basis. Deeper gravel
    will help too.

    I can't believe anyone would recommend dumping gasoline onto the


    You ONLY need to use a very small amount and it killls fast, whats
    leftover evaporates.

    Its not like someone is dumping gallons of the stuff contaminating the
    ground water

    I found that dry concrete (not mixed) makes a great filler. It
    more or less sterilizes the ground under it and as it rains the
    stuff gets pushed into the cracks and makes a good hard gravel
    that keeps the weeds down well. It crumbles of course and isn't
    "cement", but it does last a couple seasons or more at a time, in
    my case anyway. Over gravel and sand, it seems to work well.

    a neighbor wanted a gravel driveway with no mud or weeds ever.

    he had it dug out extra deep, had layer of cheap asphalt laid, then
    covered with 6 inches of compacted gravel.

    to this day no weeds mud etc. he claimed it cost less than a real
    asphalt driveway and never required sealing etc...
