Mulch: While not a plant, using mulch such as wood chips or straw can smother weeds by blocking sunlight and preventing germination.
Clover: A nitrogen-fixing plant, clover competes with weeds for resources and creates a dense ground cover that inhibits weed growth.
Hostas: These shade-loving plants have large, dense leaves that suppress weed growth while adding beauty to the landscape.
Groundcover Roses: These low-maintenance roses spread quickly and provide dense coverage, outcompeting weeds for space and resources.
