Hmmmm. Intriguing, I had not seen this before, but after googling it, it seemed to be a relativity common problem, even growing up through the drain holes in the middle of the turf. Some artificial turf manufactures recommended the use of "weed killers", but not which one.
Products like or tho ground clear or roundup max 365 are labeled for driveways, edges of lawns, gravel etc. In this case I think it would apply. But if the weeds were growing up through the middle of the artificial turf, I wonder if those products would be considered to be labeled appropriate?
(Comment from Tom Lanini, emeritus Cooperative Extension Weed Specialist with a new title)
Pulling weeds like these works OK, but sometimes the roots are hard to remove and pulling is not effective. I then resort to a high pressure water stream to hydraulically remove the soil plus roots. This works great for removing weeds in pavement cracks, but should work at the edge of fake turf. Herbicides, including organic herbicides might discolor the fake turf, so may not be ideal. Just saying...
