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)
