Do you need to use a weed barrier with the bark nuggets?

Using a weed barrier with bark nuggets is generally recommended to help prevent weed growth and maintain the appearance of your mulch. The barrier can suppress weeds while allowing water and nutrients to reach the soil. However, if you choose not to use one, ensure the bark nuggets are applied thickly enough to discourage weed growth. Ultimately, it depends on your specific garden conditions and preferences.
