Q: A few months ago, I put new weed barrier down and put new gravel. Now I have some weeds coming up. I thought the weed barrier was supposed to prevent weeds from growing?
Phil: Weed barrier does prevent weeds from growing but does not eliminate them. The weeds that are growing are “surface weeds”. They are growing on top of the weed barrier and through the gravel.
This happens when seeds from weeds drop on top of the gravel. These seeds can be blown in, or brought in from birds. They will root on top of the weed barrier but are really easy to pull. This can also happen if you choose to put new weed barrier and reuse old gravel.
