    Just yank them by hand, they come right out no problem. Just grab two fingers by the base by the soil and pull them out.

    Typical annoying warm weather grassy weed. No big deal.

    Yellow nutsedge.... The seeds are in the soil of the grower. The seeds are now in your new lawn, so as long as these things are small as shown in your photo's...........mechanical pulling will be less harmful to your lawn. It is hopeful that when you pull them out, the shallow roots can be pulled out also. Watering the grass will help you be able to pull them out easier before you start to pull. If all else fails, you can purchase a product at local nurseries called Sedgehammer (Manage), or at least here you can and it can be mixed into a gallon sprayer with spray sticker added. Spritzer sprayers are easy to find at WalMart, TSC, ACE Hardware,etc. for around 8.00 and are great for small mixes and spot spraying. You can also go to Lowe's and purchase Ortho weed b gone in a quart container that contains, 2-4D,Quinclorac,Dicamba..........Read the label and follow the directions and will take about 7-14 days to show leaf curl and death of these weeds. Sedgehammer will suppress the weeds long enough for you to water and get the grass established. First of all, mow that grass at least 4 times before starting to add herbicides to this grass as you should have some deeper root growth. The nutsedge will continue to emerge after each mowing and will need to be controlled before the roots become more established and start producing nutlet nodes. These will be next seasons monsters. Remember to mow often and not let these weeds go to seed head.
