Last year I applied round up to some poa t I had in the background. I was somewhat aggressive, but the winter did make the damage area grow even more than what I applied. The good news it seems like it really killed the poa t. But it was large enough that I had to do plenty of plugs.

19Mar Green up plus the damage area.

Here is a picture of the plugs showing 7-8in long roots in the donor plugs.

I did apply a combo of urea + AMS to the reno area but no nitrogen to anything else. I've mowed the yard around 4-5 times by now, but I'm way behind doing prem. The days I'm home, we have 50mph winds that I cant spray. I did manage to spray tenacity + NIS (4oz/a) to the reno and other area to find any poa a and pull it. I also pull soil samples, I still need to mail them.

 

Bread looks good, but those plugs look better. The things I'd do to be able to pull a plug like that. Cool stuff.

Excited to follow your journal this year g-man!

 

I want to try some of that bread. Looks amazing.

 

I look forward to following your journal again this year.

 

Hello G-man I'll keep an eye on your journal since I'm in Terre Haute and not to far from you.
Take care.

 

Bread (and lawn) look great. That gly'd area looks pretty small to me... I bet those plugs and massive roots will fill that back out pretty quick!

 

I like how you put your links at the beginning of the journal. Even with the triv spots your yard looks way better than the neighbors still.

 

I dropped some ams into the Reno area. We then had some snow, rain and cold weather. Yesterday I finally was able to do prodiamine (5g/ksqft).

Here is the Reno area

This is the old poa t area.

Last year it was like this:

 

That triv is fried. This is the way to do it.

The backyard is starting to slow down, so I did XGRN (8-1-8) at 5lb/ksqft. This should kicking just as the weather turns better. So far we had a very wet spring with not a lot of sun.

Last week I did tenacity + triclopyr to find poa a. I was thinking it was not going to be effective with the lack of sun and just cold weather. I was wrong. It send a bunch of it to seed and I had more than I expected. I used the basket to collect the clippings. Today I will spray it again (give it no quarter).

Seedheads are starting to show, so PGR should start next weekend.

This is the first I have seen in combination. What's the rate of each? How often do you repeat with the triclopyr? How does the PGR play in?

 

4oz/a of tenacity + label rate of triclopyr. The triclopyr limits the bleaching to the KBG. Weekly after this at 2oz/a. It is better to wait until the weather is warmer. I will do PGR independent of this spray.

 

Thanks for the response. Have you seen kill with this combo or just really good suppression?

 

Reno area is looking good:

Tenacity attack on poa a:

I need to do another application soon.

 

Too much travel and not enough time for the lawn.

I flew back Friday and mowed 1hr after getting home. It was too long and it missed a lot of areas even with double passes. We had rain yesterday so today I had my son use the rotary to get the long stuff mowed off.

22may2022
20-25lb XGRN (whatever remain in the bag)

10mL/ksqft tnex + 1oz FS/ksqft+ 0.5oz FEature/ksqft some AMS + CA. All in 1g/ksqft.

Traveling again tomorrow, but i think I have time to do a reel mow in the am. Hopefully the TNex + cooler weather helps slow the growth until the next mow.

 

@g-man are you doing preventative fungicide this year?

 

10jun2022

1lb ams/ksqft

A few days ago I did a bag of elemental sulfur (50lb) to yard + mulch areas to help with fungus.

Azoxy 20mL/ksqft to control the fungus I have.

 

@g-man are you doing preventative fungicide this year?

As time allows it.

 

Yesterday (11Jun2022), i prepare a tank of 10mL tnex plus 2oz FS with AMS and some DEF. I started walking to the backyard and it started to rain from a pop up rain shower. Then we had a forecasted downpour.

So i mowed this am and sprayed it this afternoon.

 

G-Man, what would be the reason for tank mixing AMS and DEF?

 

Reno picture from this morning

The backyard seems to be doing ok with the extra heat.

 

16Jun2022

I finally applied grubex. Very late.

I noticed like 20 spots of DS in the backyard. I knew it was possible with the kerns smith model at 72%. I normally see DS later in the season. The model is dropping, so i won't do anything now, but next time i will do some fungicide.

 

20Jun2022

Mow + 6oz/ksqft of Revolution. Irrigation should run tomorrow am. DS did not spread.

Overall the lawn is doing pretty good even with the heat waves and drought.

 

I am do for an update.

We had zero rain in a while. The irrigation is working along with the wetting agent, but the borders of the irrigation zone are starting to get crispy. I need to hand water those and I need to start watering the trees. One is dropping leaves. I changed the crop factor to 0.70 a few weeks ago to test out the wetting agent. But now with weeks without rain, I need to increase the frequency of irrigation to keep the borders more alive, so back to 0.8.

Speaking of trees, the front tree is gone. The company that did the work came out at 7am and did not wanted to walk on the grass. The loaded the machine from the driveway to avoid causing damage. It took them 15min to shred the tree and grind the stomp. The owner has being doing trees for 15years and all he did was talk about the lawn.

Friday and today, I've spent the day trying to get rid of all the surface roots. Some at 3in in diameter and all bundled together running for 4ft from the center. It is pain to get them out. I also sifted the soil to remove all the wood grinds. I started to backfill the hole. I'm doing it in steps: tap it down, add water, let it dry, tap again and then add another 2in of soil. Ideally this helps reduce the amount of settling. I have plenty of time before the renovation of the front yard. I still have 3-4 more roots to remove. I will take picture of the final damage once I'm done. It is not pretty.

Overall, it is nice how different the house looks without the tree there. It will also be nicer to mow that area and not fight with the roots.

 

Also, check out the poa trivialis spot in the backyard. I plug it in the spring and you can barely see it now. I think this is the way to go for poa t, late fall kill.

 

The late fall kill of the poa t is interesting and good to note you haven't had it return

Also good to see you were able to minimize the damage from the tree removal. Nothing wrong with having one less obstacle to mow around with a big green mower
