I still have time to get this resolved, from what I can tell I have to wait until the sedge starts growing its little leaflets before I can treat it anyway, so I'll keep my eyes open for the best (but yet cheapest) surfactant to use. Nate, can you tell if your sedge is coming back this year, or was last years' treatment sufficient? And did it hurt your lawn in any way? I overseeded this year with tall fescue so hopefully it won't hurt mine.
So far it looks good... I sprayed them twice last year as they came back after just one spray. It didn't hurt my lawn at all and I think it's too early to say they are gone. We had a wet spring and now with the extreme heat it's going to be a good year for weeds. I aerated this spring and already put down Milorganite, Scotts Step 1, Scotts Step 2, Iron and then Scotts Turf Builder... On top of that I've put down the following for weeds and bugs: Scotts GrubEx, two applications of Spectracide Triazicide Insect Killer (March & June) and sprayed Bayer crabgrass killer for lawns and Weed-B-Gone Max.
My yard has been a tough battle:
2005 - seeded
2006 - yard matured after lots of work and aerating & seeding twice a year
2007 - good year
2008 - cut worm infestation
2009 - some cut worms still left even after half a dozen applications and 3 different active chemicals
2010 - white grubs and sedge weeds
2011 - crabgrass started where the grubs were, but knocked out early spring
My yard is pretty good and on top of all that I've also been watering this week, so my yard is really thick and dark green right now... Going to be tough for weeds to get in this year.
