Why I Oughta...

Well, woulda look at that.  We have seedlings emerging in the blank spaces of our backyard lawn.  Specifically, we have seedlings taking off that were spread around our backyard a week or so ago after undergoing a pre-germination process of soaking them for five days .  I threw down 30# of seed (mix of KBG and Tall Fescue) and hand-spread some of it in some bare spots in the far back.  Below is a photo of one of those blank spots.  Have a look to see the grass seedlings coming up and filling in the space: A few things to note about this photo:  I spread a combination of Tall Fescue and Kentucky Bluegrass seeds back here, so I'm not totally sure what I'm seeing here, but based on germination time estimates, I'd say that this is more likely than not to be Tall Fescue.  You'll also note that there is a bunch of white blades in the photo.  That is a nice sight to see as that is Nimblewill that has been treated with Tenacity and is (hopefully) damaged ...

Earlier this month, I was able to (finally and properly) identify that I have a creeping bentgrass problem in my backyard that includes a spreading (and concerning) amount of Nimblewill .  I decided to apply Tenacity as a post-emergent in an attempt to begin to control the grassy weed ahead of overseeding this Fall.  I mixed up a couple of gallons and applied it with a pump sprayer.   What does it look like after a week?  I'm seeing what I hoped to see:  some white emerging from the bentgrass.  See below for some photos showing the white tips.  Turns out, I have A TON Of creeping bentgrass back there that needs to go.  Look at all this white showing up: Everything I've read tells me that Nimblewill control isn't a one-shot deal.  It will take a few applications the first season and a multi-year treatment plan with herbicide control (Tenacity as a selective post-emergent).   But, so far...I'm happy.  And seeing signs of p...

Last week, I shared here on my lawn diary a little breakthrough.  For the past 18-or-so months, I've been watching a grassy weed creep along and begin to migrate from my far backyard to closer to our patio.  And, after reading about various grassy weeds, I came to the (initial) conclusion that I was dealing with Poa Annua - or an annual Bluegrass.  It was showing some of the signs like being lime green.  But, after observing the lawn this Spring, I noticed that the parts affected green'd up later and seemed to handle the Summer better than the balance of my Bluegrass.   I was planning on doing a complete renovation in the back by killing EVERYTHING off and starting from scratch with a new layer of seed this Fall.  As I prepared for that, I went in to see if I could learn more about what was back there and how much I *really* needed to kill off vs. just overseed. When I went in and pulled a mature stalk of grass, I discovered it had this sort of horizon...
