    I have to lay mulch on a large area overtaken by weeds. Some weeds a getting pretty tall making it almost impossible to pull all of them out. Can I just overturn the soil and lay the mulch directly over it or should I use chemicals to ensure weed won't get through?

    Thanks

    use chemicals!!! you may also want to put down landscape fabric or sell weed maintance with pre and post emergents.

    Won't even begin to tell you how bad of an idea that is. Have you taken the time to identify each type of weed you're dealing with?

    Don't use chemicals or you may end up killing something you don't want to kill. I would till everything, rake it all out and then put on a think layer of mulch.

    lol, tree huggger..lol

    use roundup first..
    any weeds that will regenerate from tubers will not be killed by tilling.. they will be propigated ( making lots of new weeds).. also any weed seeds that are dormant deep in the ground can be brought to the surface and germinate...

    Double ditto, this is the practice for me, just got to be careful when spraying, but if your licensed and knowledgeable then you should already know that.

    Definatly use a weed killer to get rid of the existing weeds. If there is no landscape fabric, apply it now. When we are installing new mulch in beds we usually put down a pre-emmergent herbicide to prevent any more weed growth and every spring we treat all the beds in our commercial accounts with a pre-emmergent to minimize our time being spent weeding throught the growing season. Just make sure you are licenced before you start applying chemicals to clients landscapes......Hope this helps......Have a great day!

    I thought landscape fabric is typically a "no no" with mulch......

    Treat with Roundup when weeds are actively growing. Wait 5 days then apply Preen and mulch. If weeds are dormant (ie winter) or growing slowy (ie summer) you may not get complete control. Definitely do not disturb the soil if at all possible. It will just stir up more weed seeds.

    I am not a tree hugger by any means. I am studying currently to get my Master Pesticide Appilcators License. Just been finding out a lot of stuff that the back of a bottle of Round-up won't tell you.
    All has to do with opinions, I just wouldn't do it in case I wanted to ever wanted to plant there.
    good luck
