Landscape fabric causes ecosystem damage and limits functionality. There are better options for suppressing weeds.

Source: Why Landscape Fabric Should be Avoided in a Garden

There are better ways to keep weeds down and create a low maintenance space. Start by avoiding spacing your plants in an area covered with landscape fabric and imported mulch. Instead, choose eco-friendly and sustainable natural options to make your life easier in the garden.

• Select a diverse range of plants suited to your location. Perennials and self-seeders will help to create a more affordable and low maintenance scheme that just gets better over time.
• Combine plants to create areas of dense, layered planting, with less space for weeds. By choosing the right combinations of plants for your polyculture (which will not compete overly with one another), you can sow more densely, with a layered planting scheme.
• Use ground cover planting to protect the soil and reduce weed growth. 
• Line beds, borders, or pathways with spring bulbs or other plants to suppress grass and weed ingress into growing areas.
• Choose organic mulches wisely to suit the setting, and ideally source materials from elsewhere in your garden or as close to home as possible. Thick organic mulches won’t eliminate weeds entirely but they can help to keep them under control, while adding fertility and conserving water in the soil.
