I've gotten a new grassy weed in my yard this year an I am not sure what it is and how to handle it. Last year I put down 3 rounds of Dimension (mid spring, summer and fall) and this took out my crab grass problem. I overseeded late march and have held off on Dimension till 2 weeks ago but I don't think this is a form of crabgrass. It has also had 2 rounds of Impreliss Last week and a month ago. The weed has a bright green leaf, grows similar to crab grass, and grows nearly twice as fast as the fescue around it. I am wanting to know how to get rid of it. My first thought was crabgrass but is different than what was there before. Another thought is wheat but haven't used straw in the lawn. My lawn is TTTF and I've been using JDL transitions blend.
