Nobody in your town sells vapor-barrier plastic? That stuff is

See remarks above posts about "plastic".



How many decades are you planning on leaving this stuff? If you want
something that's going to last decades -- or even a couple of years -- in
direct contact with wet soils, then cotton canvas is NOT your answer. In
those cases, you want something non-organic, like a petroleum product. Like
"plastic".

Vapor barrier "plastic" (heavy LDPE) is pretty durable, even in sunlight.
You'll get several years out of it, at least.

Polypropylene tarps are almost as good, but they're "plastic" as well.

Farm-supply places (should be easy to find in your area, no?) sell weed-
control fabrics that are biodegradable. Problem is, they're also "plastic".
And they're biodegradable, which makes them just like cotton canvas.

Or is your objection to "plastic"...political...?
