Turf Type Identification - Is This Poa?

Image
I have some light-green colored (new) patches of grass in our backyard right now.  When I pull up a section of it, this is what it looks like below:  There is A LOT of root-structure at play, isn't there?  Is this a weed - like the dreaded Poa Annua?  Or...could this be Kentucky Blue Grass that I germinated and planted last year?  The color...of the patch (lime-ish green) has me worried that it is Poa. Any grass experts out there that can confirm what I'm dealing with here?  And, what I should do? One thought I had was to try an application of Tenacity?  It doesn't harm KBG and turf-type Tall Fescue .  So, it if does *anything* on this grass, that tells me it is Poa? 

We have Nimblewill In Our Lawn - August 2022

Image
I had a little lawn care breakthrough this past week.  Turns out....I don't have Poa in our lawn.  We have a bent grass called Nimblewill .  Since last Fall, I've talked about how I needed a plan to deal with what I thought was Poa Annua in our backyard .  I s ketched out the notion of a full back renovation and even included the idea in my 2022 to-do list.    But, as I was thinking about the timing of killing that (presumed Poa), I started to dig a little deeper on the Web.  I pulled a blade of my invasive grass and compared it to what I found on the Web.  It wasn't looking like Poa.  Then...I found this page from Purdue's Turf Science Department that talks about Nimblewill .   Purdue describes Nimblewill thusly : Nimblewill (Muhlenbergia schreberi) is a warm-season perennial grass found throughout the northeast, southeast, and Midwestern United States.   ...It grows well in moist, shady areas but it is also found in dry...

Using Crabgrass Preventer - Without Food (Year 2)

Image
Nat added this bag that you see at the top of this post to one of her recent orders from Amazon.  It is a bag of Scott's Crabgrass and Grassy Weed Preventer under the "Halts" product name.  It does NOT have lawn food in it - which is fairly uncommon in most crabgrass preventers. You can find this stuff here at Amazon (this is NOT an affiliate link.  I don't do that...) for $16.99. I used this same product last year - and sought it out because of the fact that it doesn't have lawn food in the mix.  Last year, I held off on feeding my lawn until Memorial Day and I'm thinking that I'm going to do the same. I laid out my full 2020 lawn care plan here in this post from February .  In that post , you'll note that I'm calling for an application of this pre-emergent in "April" versus "mid-April".  And that's because that I'm going to turn to - once again - Michigan State University and their "Growing Degree Days...
