After a year of organic my back lawn is thriving. It was newly seeded and I fertilized pretty regularly last Summer, let it grow long and watered once-weekly. But it wasn't until this spring that I'm really seeing the results. It's so thick that it's choking out almost all of the weeds. My weed hound is at risk of getting cobwebs!

But, last year I had a terrible nut sedge problem and I'm afraid that it's just lurking, waiting until I relax a bit. Can anyone tell me when I can expect nut sedge to appear?

Thanks
