    A neighbor has some landscaping installed a couple years ago. They put down landscape fabric and then stones over that. Now two years later there is a lot of grass growing in the landscaped areas. I was over there looking at it with him, and it seems the contractor installed everying like he should, its just that the grass grows throught the fabric.
    Has anyone eles had this problem? did you just spray a herbaside on the grass or can you use a steralizer?
    This area is irrigated also.

    I would guess that dirt or topsoil got dumped in with the rock- Enough to harvest grass anyways. I'd just hit those area's with round-up, being carefull not to spray on any plants or anything you don't want dead.

    That crap doesnt keep anything from coming through.. Get on your hands and knees and start pulling. Stay on top of it, so it doesnt get out of control..

    We picked some of the stones back and there does not seem to be any dirt on them.
    Its almost like the landscape fabric is not doing anything.
    The neighbor had it installed thinking that his landscape would be very low maintaince.

    The other thing with landscape fabric is where there are planings weeds can come up through the same area as the plants. I have seen where the barrier is up to the concrete and weeds sneak though between the barrier and the sidewalk.

    Landscape fabric is worthless as a weed barrier. Its sole purpose is to keep rocks and soil from mixing, and should not be used under anything else.

    Sadly, the general "professional" doesn't have a clue.

    Dirtywater is right, the sad thing is they label it as a weed barrier, I have plenty of examples where has no such properties. You can use heavy duty plastic that is not porus, but it should not be used around plantings as it will prevent water flow. All that fabric does when used as a weed barrier is make removing the exisiting rock more of a pain.

    Thanks, So I will tell him to adjust his standards for the amount of grass in the landscaped areas. He thought they did something wrong, as he was expecting the weed fabric to stop everything. He wanted it to be LOW maintence.

    Is it a dewitt 20 year fabric or the thin cheap crap that the box stores sell. When we install it we overlap seams 6" and apply a pre-emergent to control airborn seeds and spores that settle onto it. I have never had grass come through the dewitt fabric, But I have seen seeds sprout on it.

    Grass seed can sprout in dust. I'd bet your grass has blown into the rock beds and is rooting on top of the fabric.

    Use Roundup as needed. Snapshot will minimize future weeds.

    Use your head if you ever overseed that property.
