Most burlap I've seen was not tightly woven, and after the newspaper disintegrates, I think there would be weeds coming through, but can't say how soon that would happen.
A good weed block that I read posted on here by another memeber(can't recall who) is used carpet. If you contact a carpet installer and get some used carpet, cut it into squares, 4'-5' slit it to the center, cut a hole in the center for the tree, it makes a good weed block, free. Of course it's heavier to handle, but it's free, and does a great job. No need to stake it down. I have some on the ground 3 years and it has not rotted through yet. FREE.
