What kind of grass do you have?

fescue

Buy a bottle of RoundUp for Lawns and spot spray the weeds , it will take care of both. Be sure to buy the one that is safe for lawns and not the regular one, the regular one is glyphosate and will kill everything.

Also, if you put down pre-emergent next spring it will prevent 99.9% of the crabgrass. Nutsedge is going to be a long term battle unfortunately, but stick with it.

I've never seen RoundUp that didn't kill everything. For the past 50 years they have been selling a product called RoundUp that kills everything. Now they sell a product called RoundUp that doesn't kill everything. You have to wonder who does their market research??? How many people will be confused and buy the wrong one? I am notorious for getting the wrong product in a look-alike bottle or can (who knew there were so many different kinds of canned tomatoes?).

I know the nut sedge will be a battle. the funniest suggestion I've seen for nut sedge was to just move away.

I wholeheartedly agree. But it is a good product.
