About the only thing I can think of is spot treating it with Round-up. While this will also kill the lawn grass, spraying only the nut grass areas or dipping a paint roller/brush into Round-up and painting the weed will help prevent the herbicide from getting where you don't want it. It's also easier to do this when the nut grass is about 8-10" tall and well above the other lawn grass. Keep in mind, however, that repeated applications may be necessary.

No picture, but I wonder if it's nut grass. Kill it by covering with black plastic, herbicide or pulling it complete. If it's nut grass it does pull easily, but that is not effective unless you get the nut which is sometimes hard unless you loosen the soil in the area.

How to kill this stuff off in my flower beds without poisoning the soil?

If it is in your flowerbed and you're worried about killing your other plants, there really is no alternative to carefully digging up each nutsedge plant you see and continuing to do this throughout the season until it is all gone. If you don't mind carefully applying a chemical, Bentazon, Halosulfuron, Imazaquin, or Sulfentrazone should kill it if applied correctly and according to the directions on the package. Virginia Tech gives some guidelines here: http://ext.vt.edu/lawn-garden/turfandgardentips/tips/nutsedge.html
