Any bit of mulch, sand, dirt, etc will allow weed seeds that get on the cloth to grow and those roots will weave it's way down into the cloth as well. It really helps a lot but you still have to keep an eye out for things coming through and growing on top of the cloth.

Which is why I used pine straw - there's nothing in it that will help seeds germinate.

When we start our new beds, they'll be totally clear of weeds etc, and at least half filled with Black Kow, which is promoted as 97% seed free. Several years' observation leads me to believe that claim is accurate.
