100% KBG test patch (2020 KCMO) [2021 Spring is coming]

So this will be my first ever "renovation" but it will only be a patch. I am fed up with the inconsistency of my front yard. I did a fairly significant overseed with TTTF last year and it went OK but the k31 continues to take over and the TTTF wilted at the slightest bit of heat and humidity. Maybe I didn't feed first year grass enough? I don't know.

So I think I have finally (after years of contemplation) decided I want a 100% KBG yard. So this is my test patch renovation to make sure I know I can do it on a small scale before moving to my whole front yard. I also want to see what 100% KBG looks like and verify it will have the density and stand up the way I want it to.

Here is my test patch 2 days after first Round-Up application (8/17/20). I am only doing between the sidewalk, driveway, street and the light pole. This is a nice evenly irrigated spot and isolated from the rest of my yard. I wanted to stay away from trees with round up as they are young just to be safe. This was also, unfortunately my BEST patch of grass in my entire yard. It was almost entirely TTTF with some KBG and K31 sporadically.

Here is a close up so you can see grass mix:

I may just do this whole area on the right side of the driveway up to the house if I get the itch.

Here are some pics of the rest of the smallish front yard:

You can see the swath of TTTF down the middle (running left to right) that I put in last fall. Here is a closeup:

And here is why I want to redo this entire front yard:

I will be obtaining a fresh .5lb or so of BlueWave from my local GrassPad. This is a custom KBG blend they make for our area. The cultivars change every few months so you never know what you are going to get but they always use quality cultivars and it is always 0% weeds and filler. I want a mix for diversity to help with the hot and humid summers.

The renovation plan is as follows:
  • Another round of Round-up on day 6
  • after full browning, rake patch with garden rake
  • Lower mower to lowest setting and bag
  • hand spread seed
  • cover with peat moss or whatever covering is recommended by grasspad as they have a few options
  • water 2x daily for 15 minutes each

Any and all comments/questions are welcomed.

You can usually scalp after 2 or 3 days, then reapply glyphosate after removing all the dead material.

It may even still look green after a few days, but you'll see and smell how dead it is when you start scalping.

If you wait a week until its fully brown, you may end up with a mat of dead grass thats flopped over that you cant scalp, especially if you get rain. Then you have another mini project before you can seed.

Yeah, I have been unsure of that exact sequence. That is why I was going to rake before scalping. I wanted to rake up anything i could and then use the mower to bag up the rakings and new clippings at the same time. I was trying to be as lazy as possible. I figured I would have to rake no matter what. Was that a false assumption?

If it's standing up, no need to rake before you scalp. But you'll need to remove the dead crap after you scalp.

No need to rake if you have a blower. After you scalp, blow the dead crap into adjacent areas and stand up the stubble at the same time, until you see some bare soil between stubble.

Some call that lazy. I call it smart.

It looks ready for seed.
You sure? There are still green blades sporadically through the area. I was trying to get it all brown before putting the seed down as I want nothing but KBG when this is done. I am definitely anxious to get the seed down, though.

How much KBG seed can I put down? Let me rephrase, how much is too much KBG seed? In addition to my new seed I have some 1 year old blue wave mix with some different cultivars. I want to put down both groups of seeds to maximize genetic diversity but I also don't want to put too much down. I assume too much seed could lead to sprout-n-pout or something bad?

Be aware you might have to water more then 2x daily. Its supposed to be pretty warm here 90s for the next week or so. Just 2x daily might dry out depending on winds and stuff so just keep an eye on it and adjust if needed
I'm keeping an eye on the weather for sure. I work from home so I am not too worried. I can just go out an check and manually run the zone as needed...unless I forget.

Thanks for the warning.

I see enough soil to be able to seed. Do more gly to make sure it is all dead.

2lb/ksqft is the standard rate you should do. Too much seed leads to crowding and fungus.

Do you know of any good pictures showing what this density would look like? I have to drop by hand because it is such a small patch. I think I have to do it by appearance instead of weight.

Still no seedlings but I didn't expect to with this being morning of Day 5 after seed down. This is my first real go at the KBG patience game. I feel OK but with each day I can tell the anxiety is building.

Temps have been in low to mid 90s so I have upped the watering to 4 times a day for 10 minutes each. 3x a day the peat moss still felt moist right before each watering but I went to 4x a day because people on this board made me paranoid.

Pics from this morning. There is finally enough so that you can see a green tint from a distance.

I'm getting a monsoon now so maybe some of this will be gone after the rain stops. I'll have to wait and see. I think the coverage is good, the spot is flat and the baby grass has enough roots to be OK. Fingers crossed:

Damn that sucks,. I just threw some seed down this weekend and was worried we were going to get those storms but it went east of us.
I just keep telling myself "it was only 10 days worth." This is why we get seed down early, right? Time to treat these. The grass babies I lost didn't wash away. They were laying over flat and when I touched one you could see the root was in a small clump of mud. They got uprooted and just fell over. Really weird looking. Maybe they can recover? Probably not now, though because I put new seed and another layer of peat moss over them.
