Yes, landscape fabric absolutely makes weeding easier in the long run by providing a strong physical barrier against tough, established weeds. Its primary job is to block the sunlight that weed seeds in the soil need to germinate, dramatically reducing the number of weeds you have to fight.
While some airborne seeds may still sprout in the mulch on top, the fabric prevents them from establishing deep roots into the soil. This means the few weeds that do appear are usually shallow-rooted and can be pulled out almost effortlessly, allowing you to maintain a clean landscape bed with far less work.
