Removing Poa Trivialis

[@shion_lwn]

I am a lawn care newbie. I moved into a house 2 winters ago. I had no idea what I was supposed to with lawn, and Summer came, pretty much all the grass (except for some tall fescue in the backyard) were dead. Fungus and weeds were bad too. Late Summer I started looking into lawn care and did a reno last fall. grass came in ok. I saw small patches of lime green grass in the backyard, but I had no idea what they were. Spring 2021 came, lime green grass patches are Bigger, and spread..!! Poa T!! I watched your video and decided to dig out large patches yesterday. Originally I thought of going with just seeding. I seeded these areas... then today, I dug even bigger poa T invaded area. I looked at small patches that are spread and scratched my head..wondering I should lay sod on all. RoundUp takes time to fully kill the weeds. Temp is getting higher during the day. So... yeah.. It’s tough.. I think I will try your way. I am very new to sodding. Sod farms around my area only has KBG. I was told that is usual thing. My lawn grass is mixed multiple types. (KBG/PRG/CRF in front yard, KBG/PRG/Fine fescue/Tall fescue/CRF in backyard) I have been overseeding KBG&PRG only since last fall. If I lay KBG sod on bold areas, the color would be super different for a long time ? I would greatly appreciate if you could give me some advice. Thank you very much.

Great Video. I have actually used both methods in my lawn and have had success. It's definitely a battle with Poa Triv.

[@richtfan]

Actually there are a few selective herbicides you can use effectively. I am using sulfentrazone and my lawn is perennial rye and turf type tall fescue. It is doing a very good job so far.

[@ZupE891]

Yes but I hear that these type of methods kill triv in the current season, but then it just comes right back the next year

[@leonardgenovese7726]

What about using a propane torch to burn it out? I think that also kills the roots.

[@brimstonefire4221]

What sod type to buy? My grass is scott sun and shade mix.

[@ugna2773]

I just did a section. I still got more to do.

[@mikemorris8497]

I have heard that poa seeds lay dormant for years. Then when conditions are rite they sprout their ugly pale green leaves. Hope your sod job works ! Follow up in a year. Thanks for your videos.

[@meandmylawn3849]

Absolutely. They are likely in other parts of the yard as well. For smaller areas, kill and re-seed patches as they appear is the quickest option. This area was so large that getting down to the roots and re-sodding was the best option! Should have tackled this particular area a couple years ago before is spread so much.

@@meandmylawn3849 how’s it looking this year?

[@user-kj5uc9vo9d]

It's going to come back. And there are two selective herbicides that kill it: Acclaim and Velocity PM

[@jonmernick780]

I have a better way, 1). use tenacity to turn it white. 2). i use certainty at 1/3 strength and hit the areas 3 times in 3 weeks. 3). i spread several bags of peatmoss and grass seed when the triv turns brown. My lawn is kentucky blue and short fescue and some tall fescue( which certainty kills, i dont want tall fescue anyways). Over 1/2 my lawn was poa triv when i started in the spring, now i have a couple of small patches of triv left. Nice thing is the triv stays white for like 3 weeks or more so very easy to kill off. When I used roundup it all came back

[@DrCbass123]

You start this any particular time of year?

[@DrCbass123]

And where did you find certainty? Been looking around for it online and no luck.

[@Ergo8152]

Tenacity good advice. Gotta read up on certainty never use b tenacity will definitely turn it white

[@jonmernick780]

@@DrCbass123 I started last year in may, my triv is just about all gone, just along my neighbours yard, even my tall fescue was kill off, which i didnt want

[@jonmernick780]

@@DrCbass123 I found it on amzon.com, this year I havent seen any triv, my neighbour's yard is full of it

[@mikebrown8180]

you probably just reintroduced more triv with the cheap Top soil. JMO

[@bobwelshon979]

This is good information, but I found myself struggling to hear your narration over the background music, to the point I had to quit watching. I would adjust your levels or kill the background music all together. I have been fighting Poa trivialis for 4 years now, and have read countless articles on the subject. I killed off the poa triv in May with multiple applications of glyphosate throughout the next few months, and did a complete renovation this September. It's back again, and each time I mow, I see more. I try to pull it out down to the root wherever I see it. I know I am in store for another difficult year.

[@critterdude311]

The problem with just spraying glyphosate is the seed and stolons remain viable in the soil. I think given the option, sod cutting is the best way to handle it. I feel for you, it's a real pain in the neck and flares up the OCD in us yard nuts something terrible.

[@bobwelshon979]

@@critterdude311 Yeah, it's a never ending battle. If there was one way to handle it that would make it go away forever, I think everyone would would be doing that. I haven't found that yet, and from what I read, neither has anyone else.

stuff always comes back

[@majikman7355]

Sod is going for 10 bucks...I'm about to go sell my lawn...poa t blows...I'd say over the last two two years it's gotten worse... dug it out as well..
