How can I maintain weed-free garden paths in my outdoor space?

To maintain weed-free garden paths in your outdoor space, you can start by laying down a weed barrier fabric before adding any gravel or mulch. Regularly inspect the paths and manually remove any weeds that may appear. Applying a pre-emergent herbicide can also help prevent weed growth. Additionally, regularly sweeping or blowing debris off the paths can prevent weed seeds from settling and germinating.
