Yes, it is recommended to put landscape fabric under a fire pit. Landscape fabric helps to prevent weeds from growing up through your fire pit area. Here are some tips for using landscape fabric under a fire pit:
Measure the area where you want to install the fire pit and purchase enough landscape fabric to cover that area.
Cut the landscape fabric into pieces that will fit in the area, leaving a 3-inch overhang on all sides.
Overlap the pieces of landscape fabric by at least 3 inches to prevent weeds from growing through the gaps.
Secure the landscape fabric in place with landscape pins, which can be hammered into the ground to hold the fabric in place.
Once the landscape fabric is in place, you can add a layer of gravel or other non-flammable material on top to create a stable base for your fire pit.
Remember that landscape fabric alone will not provide adequate protection against fire. Always follow safety guidelines for installing and using fire pits, including keeping them a safe distance from your home and other flammable materials.
By following these tips, you can create a safe and weed-free area for your fire pit to enjoy.
