Algae, weeds & buildup

Weeds in artificial grass grow on top of it, not through it

Turf with a weed barrier and a proper base does not get weeds from below. It gets them from above: seeds blow in, land in infill full of pollen and leaf litter, and grow in that. A yard with weeds is a yard with dirty infill, and the fix is the clean, not a herbicide.

Why are weeds growing in my artificial grass?

Weeds in artificial grass almost always grow from seeds that landed on the surface and rooted in organic matter that has built up in the infill, not from soil underneath. The permanent fix is removing the organic layer: pull the weeds, power-brush and flush the infill so seeds have nothing to root in, and keep debris off. Weeds along the edges and seams can come from below and point to a gap in the edge or a seam, which is a repair. TIMELESS Turf Restoration removes weeds and cleans the infill across the Grand Strand.

Where the weeds are tells you the cause

  • Scattered across the lawn, small and shallow-rooted. Airborne seed rooting in organic buildup in the infill. The infill is dirty. This is the common case.
  • Along the edges and borders. Soil is meeting turf at a gap, or the edge has lifted and let soil in. A cleaning plus an edge repair.
  • In a line. A seam has opened and soil or seed is getting in. Seam repair.
  • Big, deep-rooted, coming up through the turf. Rare, and it means there is no weed barrier or the base was never done. That is an install conversation.

Removing them

Pull small weeds by hand while the turf is damp; the roots are in loose infill and come out clean. Do not use a hoe, a wire brush or a string trimmer on turf. For a heavy crop, a turf-safe weed control applied to the leaves works, but it is treating the symptom. The cause is the organic layer, and that is what a deep clean removes: power brush to lift the layer, flush the infill, and the seeds have nothing to grow in.

Moss

Moss is the same story in the shade: it grows on the organic layer in damp infill along the north side and under trees. It comes out with the algae treatment, and it stays out if the strip is kept clear and drains.

FAQs

Related questions

1Can I use Roundup on artificial grass?
Glyphosate will not damage the turf fibers, and it will kill the weed. It also will not fix the dirty infill the next seed lands in. Use it sparingly if you must, keep it off borders, and get the infill cleaned.
2Does artificial grass need a weed barrier?
Yes, and properly built turf has one under the base. If large weeds are coming up through the turf itself rather than rooting in the infill, the barrier is missing or failed.
