What do you put down to stop weeds coming through?
Mulching involves covering the ground around plants with a thick layer of material that smothers weeds. Plus, mulch has the added benefit of helping the soil retain moisture. Use a layer from 4 to 6 inches deep of organic material, such as wood chips or composted leaves, to prevent weeds from growing.

Keeping this in view, how do you stop weeds from newspaper?
Subsequently, question is, 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!
Spread newspaper over the area, eight or 10 pages thick. The paper can be weighed down with stones and covered with half an inch of potting soil or compost. Spread just enough to cover the newsprint; then water the area. Continue to water the newspaper mulch every day unless it rains.
Mulch helps minimize weeds but also retains more moisture and helps moderate the temperature of your soil. The trick to keeping weeds from growing through your mulch is to put a layer of weed barrier underneath. Pull up any weeds that are already growing in the area you want to mulch.
This was a neglected bed overrun with weeds. I weed-whacked them down, covered in cardboard, and applied mulch. No more weeds!

Should you use newspaper or cardboard?
Using cardboard and newspaper to smother grass to make a flower bed is easy and effective. It isn’t too complicated, but you just need to make sure you use enough newspaper or the right kind of cardboard. We have written many times on different ways to remove grass, and this is just another tool in the arsenal for you to use! So, this simple guide will show you all that you need to do to expand your gardens by using newspaper or cardboard to smother and kill the grass. The cardboard/newspaper are a synthetic, yet biodegradable component to mulch and prevent weeds.
- Identify the area you want to kill the grass. I find it best to make a small outline with a shovel, or trim up the perimeter a bit. Doing this helps me visualize what I want the final flower bed to look like.
- Lay down news paper or cardboard over the area you want to kill/smother. If using newspaper, apply at least 10 sheet thickness.
- Weigh down the cardboard / news paper. If making a vegetable garden, you may just need to use some rocks or bricks to kill the grass. If making a flower bed, then just apply your mulch! Now you have a biodegradable weed barrier that is just as effective as landscape fabric.
