Newspaper weed barrier. Use several sheets of newspaper or cardboard around plants in your flower beds to control weeds or grass. Just spread it out, wet with a hose and mulch over the top. The paper will decompose over time and encourage good earth worms. This is also a great way to naturally remove grass to create space for a new bed.
Cardboard, newspaper and other compostable material is a quick and easy fix for weed problems. In just one growing season, you can reduce weeds by 75 percent or more. Just place pieces of cardboard around the plants you want to protect. Water immediately to help the cardboard stay in place. You can add soil or mulch on top to reinforce it, too. The cardboard will suppress the weeds and eventually break down into the soil, adding useful organic matter.
