OKC Bermuda to SPF-30 Hybrid Bluegrass Renovation

Hello,
Well on a whim I've decided to do a renovation in my backyard. I live in Oklahoma City and I have always loved Kentucky Bluegrass. Well, after reading one of the threads in the Warm Season section on someone growing SPF-30 Hybrid in Texas I thought I would give it a shot. :)
I have common bermuda in my 2000sqft back yard. The back yard is the only yard I will be focusing on before I move to the front. It's mainly common bermuda and it looks pretty decent. My neighbors have some trees so there are a couple areas that struggle with sunlight hence why I'm gonna try this SPF-30 out.
I'm trying to devise a plan on the fly as right now is a great time to start this renovation.
I have ordered some 41% glyphosate and a 2 gallon hand canon.
I need to order the seed, but does anyone have a recommendation where to buy?
I need to order some Tenacity too so weeds don't get out of control

Here are my steps so far.
1. Apply a round of glyphosate along with 1lb of Urea, then wait a week
2. Apply another round of glyphosate to hit any stragglers that were stimulated by the urea.
3. Scalp as low as I can go to remove dead grass.
(From here on is where I'm a bit unsure.)
4. Power rake with my Sun Joe Dethatcher (I've been told not to till up the ground bc it could cause a weed explosion)
5. Buy some good top soil and compost from Lowes and spread it around the yard.
6. Throw seed down. (how many lbs for 2000sqft?)
7. Throw peat moss on top (how much?)
8. Apply a blanket application of Tenacity.
9. Water, water, water,

That's it :)
Please feel free to correct anything in my list of things to do and also give me all the tips you can give. I am totally new at renovating so I am very flexible in what needs to be done, I just want it done right.

Here's pics of my yard taken recently

I have 41% Glyphosate and a Chapin 2 Gallon sprayer ordered and should be here in the next 2-3 days. I have a little chihuahua so when I spray my back yard I will spray half of it at a time. That way little man can do his business :)
So half the yard one day, wait 24 hours and spray the other half.
Is 24 hours after application long enough to be safe for my dog to walk on it?

Starting to brown :)
This is my first time using glyphosate. I thought it would work a bit quicker similar to my Spectracide weed killer.
Oh well, on to the other half of the yard later today.
It's kinda sad to see the yard I worked so hard on be killed off. Hopefully the new grass will be well worth it :)

The last half of the yard 54 hours after the first glyphosate/urea application. For anyone who hasn't used glyphosate, it works nowhere close to as fast as weed killer. Got to be patient :)

One week after first glyphosate/urea application. Looking good. Going to do atleast 2 more glyphosate only applications. I want to kill it dead! I may up the concentration a bit on my mixture.
We've had a bunch of rain lately, so the moment I get a good stretch of 2-3 days of good weather I will begin.

2nd glyphosate application applied yesterday/today for both halfs of the yard. This go around I used this Round-up concentrate. Coming along nicely! I may end up doing a 3rd app, we'll see...

This weekend I think I'm going to apply some liquid aeration formula while I wait on the gly. I'm not going to be able to use an actual aerator, so this is all I've got. Hope for the best!

Following. I recently put SPF-30 in my back yard. Waiting for it to pop up now. With everything I've read about this grass I'm so pumped about seeing how it does. I've got the perfect back yard area for it.
Nice! Yeah it looks like some beautiful grass. I've always wanted KBG ever since I developed an interest for lawns mainly from watching all the youtubers with northern type grasses. Their yards are sooo nice and lush. Hopefully, I can have a nice lush KBG backyard and then a nice reel low Tahoma 31 bermuda front lawn (When I get around to renovating the front :D )

After the 4 straight days of rain there was finally a nice stretch where I could scalp down the back yard. The southwest half looks good, but hiding under the dead grass on the southeast side there was a bunch of little green blades of grass trying to grow :x Looks like that half will get another round of glyphosate. While that's marinating I am going to take my string trimmer and beat down the other half of the lawn to try to get it down to soil. We'll see how that goes :? :D Oh, also I just bought 5 3-cubic yard bags of peat moss, Scott's Starter Fert, and some liquid aeration ordered on Amazon from Simple Lawn Solutions called Liquid Soil Loosener.

The area in red is where I'm getting green growth.



Looking good on this side :cool:

I posted this in the "Warm Season" section to try to get some help

"I'm trying to reno my back yard from common bermuda to SPF-30 Hybrid Bluegrass, but this dang bermuda won't give up. I've hit it now with 4 applications of glyphosate!! After the third round I scalped as far as my mower would go then used a string trimmer to go further and sure enough there are lots of green stolon's imbedded in the top portion of the soil. That's when I hit with the 4th app.

How in the world can I get this bermuda completely killed so I can move on to planting my seed? Am I safe to just move on the the next step and dethatch the crap out of it with my Sun Joe? I'm running out of time :(

Here's part of the yard with some of the green still all over the place (You can't tell from this pic, but trust me haha)"

Spent allllll day dethatching, raking, mowing, dethatching some more, raking some more, mowing some more. I am beat!!
Well, the liquid aeration I bought said NOT to use within 30 days before or after laying down seed. So, I sent that back and bought a yard butler aerator. That should arrive Thursday and hopefully I can get seed down Friday or definitely by Saturday. Bermuda is not 100% dead. In fact, I think I've invigorated it with all the dethatching and raking and mowing haha. Oh well, we push on forward!!

My little buddy wondering what I'm doing to his yard :)







Here's the green I found after weed eating the lawn and getting down to the soil. It's all over :(



Here's tree root knots sticking up. These are all along the back and west side of my yard :evil: I don't know what to I'm gonna do with them.

Used the scarifier attachment on my Sun Joe and that really turned up the soil. Sadly, a tree root wrapped around the blade and busted the machine. It won't spin now :(
Also, got aeration done on this side.

FINALLY SEEDED!!!!!

It took longer than expected, but the SPF-30 Hybrid Bluegrass is down!

Whew boy I didn't take into account the effect this would have on my body LOL. In my mind I had this done in just a few days but my body was not having any of that.

I still have to put down peat moss and then Tenacity to button things up. We are expecting rain tomorrow so I need to get everything finished up and let the rain do its thing.

A week after seeding I can see some bermuda popping up in a couple spots. Pretty sure the bluegrass hasn't germinated in a week. Also, I wish I was able to work a day or two more getting the lawn a bit more level. My body was so sore and I was running out of time to get seed down that I wasn't able to. Just have to top dress once the lawn is established.

The waiting game continues...

This Saturday morning I decided to rent a lawn roller from Home Depot. I've seen sprouts now for about 2 days but I am gambling the seedlings are too small for the roller to afflict any damage.
Anyway I rolled the lawn and it is SO MUCH BETTER!! It's nice and firm and flat. I'm so happy bc as stated in a previous post my regret of not tackling much leveling during all of this. Best $17 I've spent lately :D
Sprouts are coming along nicely. Wish spring would hurry up and get here!

After weighing my seed bag I noticed I put down just above 4lbs over 2ksqft. That is at the bottom of the recommended range. So I applied another 2lbs of seed. There is nothing I can really do as far as optimizing seed to soil contact at this time so I'm just gonna cross my fingers. The seedlings that are sprouting will hopefully help hold the new seed in place. To top things of my area is forecasted to have beautiful weather for the foreseeable future so that's a plus :D

Currently 14 days since initial seeding.

16 days after seeding.

When they say KBG is slow to germinate and grow boy they mean it. To the naked eye I felt like I am starting to get a lot of green up, but the pics I took show otherwise. Yesterday I did buy 4 bags of top soil from Lowes to spot fill some dips around the yard. Figure as well as leveling that would also help cover up some of the seed I put down a few days back.

The grass is finally becoming visible on my security cameras :D
One thing I've noticed the grass is doing is it hasn't grown much taller, but the single blades of grass that have sprouted are now 2-3 blades of grass.
Sslloowwllyy but surely it's trying to fill in.

18 days since seeding.
