I would welcome comments from some of you more experirenced gardners. My garden consists of about a dozen beds of various sizes (15x5 being common) with grass walkways in between. The walkways are wide enough to run a lawn mower through them. I've considered killing the grass. I have an old swimming pool liner that I am thinking of cutting up into strips and laying it on the walkways for a while, so I can kill the grass without resorting to chemicals.
Any thoughts of having grass near and through a garden? Is it likely to house and breed flea beetles and other insects, and would you recommend getting rid of it? Or would you consider it to be harmless and possible aesthetically pleasing (it does look nice in the summer to have nice green pathways through the garden)>
