Have noticed since I sprayed Celsius (now 3 weeks ago) that I now have a bunch of brown little seedheads in my bermuda. Rest of the grass looks good, but all of the little brown seedheads affect the color a little bit. Not sure if the links to photos will work (can't get to postimage at work).

Compare that with even just last week where the grass looked basically the same, but there were a lot less dead/brown seedheads

Could this be from the Celsius? Something else?

I don't believe that it is from the celsius. If it was I would expect more damage and would think it would have occured before now if you sprayed 3 weeks ago.

It's that time of year for seedheads and that is how they look when they are cut. Using a PGR (plant growth regulator) can reduce the amount of seedheads or eliminate them almost completely however it would have needed to be applied before now. They will run their course and be gone in a few weeks.

I use a PGR for my front lawn and cut around 5/8 " with a reel mower and don't have any seedheads. My back is a different story. I don't use a PGR and cut much higher with a rotary around 1 " - 1.5" inches. I believe lowering your HOC (height of cut) can help as well or at least cutting before they appear.

Forgot to mention.........your lawn looks great!

Thanks, @booneatl! It's a work in progress. Still pretty new to the lawn thing. This was sodded exactly a year ago. PGR is on my list of things to add to the regimen, but other things have taken priority this spring (like building a shed so that I can store more yard toys :lol: ). I'm cutting with a reel at about 0.75", but I know that my reel needs backlapping...afraid to backlap at the height of growing season, though, b/c knowing me I'll screw it up and end up having to go back to the rotary. So might just suffer with it for the season and backlap in a few months.

You can probably see on the other side of my fence the wild expanses of clover in my side yard. Later this summer (or next year depending on time) I plan on trying to kill the weeds out there and plug w/some of the Celebration and see if I can take back the side yard.

In my experience, that damage is being cause by your mower. It's not making a clean cut and it pinching the seed head, or the seed head is too tall to make a good cut and the reel it beating it up. Looking at your surrounding grass, I think it maybe the later of those two.

+1 It could be that you were cutting the grass and seed heads, and they weren't standing out as dramatically as mine do, and you're just seeing them after they've dried out and died. Before you mow again, look over the area, and see if you notice any seed heads. Mow, then see if they're visible. If they are, then check your quality of cut like Red said.
