Why I Oughta...

Out in the yard recently - with the snow melting away - and I notice some interesting contrasts appearing in the lawn in a few pockets.  See below for a photo showing what appears to be a darker, finer-blade green patch of lawn in the yard that (at first glance) seems out of place: What the heck is this?  At first, my brain raced to think about if this was an invasive turf - like the Nimbleweed that I discovered last year.  This patch is darker green and a different texture from the rest of the lawn.  I stared at it.  And stared at it.  Then it hit me:  this is a patch of Tall Fescue that I overseeded last year during a renovation .  For the most part, I attempted to mix the Tall Fescue seed in with Kentucky Bluegrass seed, but in the section closest to our patio, I didn't mix them.  Why?  Because that section is/was all KBG.  So, by overseeding with Tall Fescue, I was attempting to get a blend of the two.   That patch above is a bit more Tall-Fescue-exclusive than what I was going

This past season, I finally figured out that our backyard was infested with a warm-season grass/weed called Nimblewill and came up with a plan to treat it in place while not doing a full cool-season grass renovation.  That started with using a post-emergent spray called Tenacity  - which caused the Nimblewill to white-out and die .   Once that ran its course, I then began a project using a pre-germination seed technique followed by a project to overseed the lawn with a mix of Kentucky Blue Grass and Tall Fescue .  Which...after some watering... resulted in a bunch of new germination . And, while I was happy with the result in the Fall with new, green grass filling in plenty of bare spots, I knew the real, important results, would be visible once the lawn went totally dormant.  That's because, the Nimblewill is a warm-season grass and totally dies back once the temperature drops.  Which, historically have left us with a bunch of bare spots in the lawn and other areas with white,
