invasive non-lawn grasses
I've two very unique "grasses" that over past few years have taken toll on my carefully maintained lawn, regardless of several back-breaking bouts of ripping them out and re-seeding. Not sure what they are, what I should or can do to eliminate/reduce their impact. Since this interface allows 3 images, I'm breaking it into 2 separate email Qs: 1) the first I believe is a true grass, but rather than being straight, thin, soft on feet as other lawn grasses, this has broad, dark green leaves, and they've a tendency to cluster into "pin cushions". pulling out such a cluster, the roots are shallow, small ball-like thin fiber roots. I've attached a pic of these, "thick pin cushion". What specific grass is this, is it found in grass seed mixes, how can I reduce its spreading? thanks again
thanks- I thought it was a type of fescue, and it is likely in some seed mixes. I try to avoid those.
