Landscape fabric, also known as weed fabric or weed barrier, is often used around trees for several reasons:
Weed suppression: Landscape fabric acts as a barrier, preventing weed growth around the base of the tree. It helps to suppress weed competition for nutrients, water, and sunlight, reducing the need for manual weeding or herbicide use.
Moisture retention: By blocking weed growth, landscape fabric helps retain moisture in the soil around the tree. This can be particularly beneficial during dry periods or in areas with limited water availability. Conserving soil moisture can promote healthier tree growth and reduce the need for frequent watering.
Soil erosion control: Landscape fabric helps stabilize the soil around the tree, preventing erosion caused by wind or water runoff. By maintaining the integrity of the soil structure, it protects the tree’s root system from potential damage.
Temperature regulation: The fabric acts as an insulating layer, moderating soil temperatures around the tree. It can help protect the roots from extreme heat or cold, creating a more favorable environment for root growth.
Protection against mechanical damage: Placing landscape fabric around trees can provide a physical barrier that protects the trunk from potential damage caused by lawnmowers, trimmers, or other equipment. It acts as a buffer, reducing the risk of accidental injury during routine maintenance tasks.
When using landscape fabric, it is important to properly install it by cutting a hole in the fabric to accommodate the tree trunk, allowing room for growth. Additionally, covering the fabric with mulch can enhance its effectiveness and provide additional benefits, such as further weed suppression, improved aesthetics, and moisture conservation.
It’s worth noting that while landscape fabric can offer advantages, it is not a foolproof solution. Over time, weed seeds can still find their way onto the fabric and begin to germinate. Regular monitoring and maintenance are necessary to ensure the fabric remains effective.
