Yes, we recommend using infill for landscape grass. As for what kind of filler material to use, please consult us.
The fibers used to make artificial turf are usually made of polyolefin (polyethylene or polypropylene). Polyethylene (PE) and polypropylene (PP) are semi-finished products, both made of petroleum, and are the main components of many man-made products such as plastic bags, plastic containers and artificial turf fibers. Different raw materials and manufacturing processes will ultimately determine the quality and price of the finished product. The difference in quality may not be seen with the eye, but the difference does exist.
