Will Newspaper Stop Weeds from Growing?

Newspaper breaks down quickly, usually lasting no more than a single season. This makes it an inexpensive option for annual vegetable and flower beds. Like fabric, newspaper allows moisture and oxygen to reach the soil while suppressing weeds, but it also decomposes and adds organic matter to the soil.

How many layers of newspaper kill weeds?

You'll need to weed your beds first and then lie down a thick layer of 8-10 sheets of stacked newspaper. (If you run out, wet cardboard will work as well) Cover with a thick layer of mulch (about 3″) and you'll be weed-free for a few years before you need to lie down anymore!

Does newspaper prevent weeds from growing?

Newspaper, as we have discussed before, makes weeds instantly disappear. And it prevents them from re-emerging for an entire season, if not longer.
