What is this sprouting up in my lawn

Isn't that your grass going to seed?

looks like grass going to seed

[Genofish]

Thats is what i was thinking. Why is there more areas this year and why does it do it?

[hoggs222]

I had that and just mowed it a couple of times and it looks normal now.

It seems like a lot of yards are doing that this season. Tons of my clients are having this same problem. Some odd clumps of grass are going to seed at lower than normal heights.

Just mow it off and it will go to normal in a few weeks. I really think this long cool wet spring is causing an extended peak growing season for turf.

To be on the safe side I would bring a sample of this grass into a turf specialists and have them determine what type of grass it is.

If it was your Kentucky Bluegrass going to seed it would not be in isolated clumps. The grass blades look thinner than the rest of the grass.

I had this show up in my yard after putting down bentgrass for a putting green and it has spreed to other areas. Late summer / fall theses grass clumps will have very shallow roots.

The only way to get ride of it will be to put round-up on the clumps to kill it totally and than I would reseed or sod the patches.

It could also be annual bluegrass which is bad as well.

Trust me, if it is not Kentucky Bluegrass and it is bentgrass you will want to take care of it before it spreads to far.

It does look like Poa Annua (Annual Bluegrass).

Easiest way to get rid of it is by digging it up (make sure you don't leave any seeds behind), and fill in the bare spots with some soil/seed mix.

Poa has a shallow root system and does not do well in hot, humid weather and may die out leaving patches of dead turf and will eventually fill back in when conditions are right for the seed to germinate. It also does not do well in severe winters. Alot of times, after snow melts and lawns have bare spots, it possibly is that the area was poa and it died off over winter.

If untreated, it can and will spread like crazy.

Speaking of Bent grass.This stuff is nasty and spreads like wildfire. The past 2 years i have had patches of Bent grass pop up in differnt areas of my lawn and neighbors. I must spread by going to seed? I am in the process of killing that with round up and then re-seeding as you are. I am not sure where this bent grass came from but i did put in a sprinkler system 3 years ago and had to re-seed where i dug. It may have been in the grass seed i put down. here is a picture of the bent grass i posted last year.

Bentgrass is spread by stolens (above ground horizontal roots) and can be killed with a broadleaf herbicide.

If you golf, it can be possible to pick up the seed on your shoes and after you walk in your lawn, it can start to grow eventually.
