Proper Installation for Weed Prevention:
Spread about 3" - 4" deep layer across existing soil or garden area where you are using the bark or mulch as a top dressing. By using atleast a 3" layer of mulch or bark, you will be blocking out the sunlight from reaching the soil and sprouting weed seeds. Weed barrier is not recommended in areas where using mulch or bark as a top dressing. Weed barrier over time will prevent decomposition of the wood mulch or bark and their nutrients getting into the existing soil. Over time the underlaying soil will die and be completely depleted of necessary nutrients. Also the use of weed barrier will not allow for the mulch to adhere into the soil and keep it in place. During wind storms the weed barrier allows for the mulch and bark to be carried away more than if it was placed directly on the soil.
