The previous owner put down canvas weed deterrent underneath a few flower beds. We are now trying to turn these beds into grass to increase the size of the lawn.
Do I need to try to pull up all of the canvas? It is deeply embedded in the root systems of weeds and plants and starting to fall apart. I've taken up a few chunks, but it is difficult to get it to come up in one piece without tearing. If I leave the canvas in the ground, will the grass be able to come in? Will the canvas affect the quality of the grass when it does come in?
The canvas is buried between 4" and 8" under the soil (the depth varies).
