OK, first I am in SE PA if that means anything. My lawn is a blend of
bluegrass and fescues with the latter dominating. Lately, I've been
getting these clumps of yellow/green grass. They are individual shoots
with somewhat larger blades than fescues. The stuff grows faster than
the rest of the lawn. That is I can mow and two days later, this weird
grass is already two inches higher than the lawn. It's somewhat easy to
pull if you grasp it by the crown. However, there is enough that I am
losing the pulling war.

Any thoughts? Suggestions?
