Your artificial grass is shedding fibers. Here is when that is normal, and when it is not.

Fibers are not glued down individually. They are stitched through a primary backing in tufts and held in place by a latex or polyurethane coating on the underside, called the tuft bind. A little loose trim fiber left over from manufacturing works free in the first few cleanings and weeks of foot traffic on a new lawn, the way a new carpet sheds; that is cosmetic and stops on its own. Real fiber loss later means the tuft-bind coating has aged past its useful life under years of UV and heat, or been attacked by something on the turf, and the stitching lets go so whole tufts pull free instead of single fibers. Separately, running a wire brush, a metal rake, or a stiff steel-bristle attachment over turf, rather than a synthetic-bristle brush, physically tears or loosens fibers wherever that tool went.

New-lawn shed is fine, short bits that come off a broom or your hand, with no thinning visible in the pile and no backing showing. Run your fingers through a section; if only a few loose fibers come free and the pile still looks and feels full, that is normal. Backing failure looks like small clumps of several fibers still bound together at the base pulling free with modest pressure, with thinning or bare backing starting to show, usually first in high-traffic paths or the oldest, sunniest section of the lawn. Wire-brush damage shows as frayed, bent or missing fibers following the strokes of whatever tool was used, often straight lines or one worked-over area rather than a traffic pattern.

New-lawn shedding needs nothing beyond normal grooming; it resolves on its own. Backing failure cannot be re-glued fiber by fiber. Once the tuft bind lets go in a section, that section is cut out and replaced with a matching patch, the same as any other repair; if it is showing up broadly across an old lawn rather than in one spot, that is the turf reaching the end of its service life, a bigger conversation than a patch, and we say so rather than patch a lawn that is failing everywhere. Wire-brush damage is treated the same as any torn or frayed section: brushed and trimmed if minor, patched if the fibers are genuinely gone.

Always use a synthetic-bristle brush or a power broom made for turf, never a wire brush, metal rake or stiff-tine landscape rake, anywhere on the lawn; that one habit prevents the entirely avoidable kind of shedding. On a lawn showing early backing wear, a Premium Restoration on schedule catches it before it becomes a bald patch, and keeping infill topped up evenly, since thin infill stresses the base of each tuft, slows the natural aging of the backing.
