I've planted thousands of Labatt blue bottle caps over the years with little success, I haven't figured out if its timing or seed depth, but I keep on keeping on !
Fugging commie.
Maybe try Molson caps?
Molson goes skunky in those green bottles, might as well try to drink warm buttwieser !
I guess I could just buy a Ford, get a poodle, and drink ditch water !
