Is this weeds or grass going to seed? I'm not sure what it is but I have a lot of it in my back yard this spring after aerating and seeding last fall. I don't recall seeing this before and I've been here for over 20 years. I'm hoping it's just grass but I'm betting on weed. If it is weed, what would the best course of action be or is just a good lawn weed killer the best bet.
Thanks in advance!
