Poa Constrictor - Did It Eliminate Poa Annua?

[@PacificNorthwestLawns]

I’ve scheduled a lawn care enthusiast meet up here in the Pacific Northwest for Saturday August 13th, 2022 - Check out the details! kzbin.info/www/bejne/eom4lal4bNJjasU

[@michaellord1389]

I've seemed to get a handle on the Poa on my home lawn and my baseball field with consistent applications of PGR. I still see the Poa "color" but as many seed heads as in normal years. It could also be that I mow and just about an inch. I love that you show the "realness" of lawn care. Not all is perfect. I feel like a lot of lawn you tubers only show the perfect stuff, when in reality that is never the case. I will be there on the 13th!!!!

[@PacificNorthwestLawns]

There's something to the PGR but I think it's mostly a suppression. I'm looking forward to seeing you there Mike. 🍻

Thanks Keith! I'm excited to see how that Pro Vista works out. If it ever becomes available in my area I may just try that!

[@drlovety]

Great thing for a KZbinr, more content. Thanks for being transparent. I've seen so many KZbinrs show that a full reno will create a perfect return. That just isn't the case. Conner is dealing with the same. He is torching his lawn, is that to kill off the seeds? I hope it works out for you but I don't think it'll be any different. I think our weather is perfect for POA growth. Good luck, I hope it's enough. My Reno to remove the POA was getting a sod cutter and bringing in new soil. I also seeded early. POA was still here, but much easier to pull out, less widespread.

[@PacificNorthwestLawns]

I seen what Connor has be up to. He's had the same issue for a while now. I think he's burning his lawn just to help get the debris cleared up. I doubt it's gonna help much with seed that's already in the soil.

[@dougstucki8253]

I'm in western WA too and have kind of resigned myself to just having Poa in my grass. We bought our last house brand spankin' new with a beautiful sod lawn installed. For several years I kept it beautiful, but Poa eventually gained a solid foothold despite my best efforts to extract it by hand. I'm convinced that you either have to fight it non-stop with pre-emergent and selective post-emergent treatments, constantly pull it out, or just accept it and try to live with it. We've moved and our back lawn has just about every kind of grass you can imagine. It's a moderate disaster, complete with uneven collapsed mole tunnels. I picked up some Q4 Plus and am going to hit it with that first and see what remains. Then I'll level it with the germinated soil/sand/seed mix. It might be a while before this lawn looks good.

Wanna post that schedule for PNW that you got from forum. I was able to do 2 applications last fall (Aug 8 & Aug 27) and then did one in spring on day of no rain. Have been very surprised how successful it’s worked. I’ve only had two patches come up in 5000 sq ft lawn this year that I just hand pulled. With our super mild spring this year it’s not a surprise. I am planning to do same approach to get two apps in August and then another next spring. Hoping to completely eliminate soon

[@PacificNorthwestLawns]

Not sure which schedule you're referring to from some forum but I didn't get any schedule from a forum. Are you referring to the studies I mentioned? It's in the comments section of the post I made on the community tab 2 months ago. I pinned the comment to the top.

[@PacificNorthwestLawns]

Wouldn't spraying a pre emergent now prevent germination in the fall? I guess it depends on what you're using and how much.

[@Tundra_Guy]

@@PacificNorthwestLawns Exactly. Make sure you use tenacity instead of a Pre M.

[@Tundra_Guy]

@UCaiUdRwe68qVOKtF4N7Lj6g I know this. I would use it at seeding time and it should give you at least 1 month's protection. I would even go further and apply it a second time instead of your pre M. If you have any bare spots left, you're screwed with Pre M.

[@jandacy4759]

I'm with you on this... I put down the glyphosate this week. Do you think mid August will be safe for putting down seed? This has been an interesting Spring/Summer... Hope you have success with your renovation.

[@PacificNorthwestLawns]

I think it'll be just fine. I'm shooting for mid August myself.

[@haroosudra4081]

My second plan is to may be reseed and use Tenacity. What would a ideal time to apply Tenacity- on perennial and KB grass?

[@PacificNorthwestLawns]

If you're reseeding and are going to use Tenacity you do it at the time of seeding. It's used as a pre-emergent when seeding. Understand though that even in the most ideal conditions its only effective for 3 maybe 4 weeks if you're lucky. reality is probably 2 weeks at best with all the watering you'll be doing.

[@haroosudra4081]

Thanks

[@driximus]

I killed off part of yard to get rid of it last year. I wish I would have a bit started growing earlier near August in the second week. Spayed, watered, let the random stuff grow. Repeated it three times. Should have done 4 times. 😅

[@PacificNorthwestLawns]

That's my plan. Seeding the second week of August.

[@jcs1758]

I'm in northeast ohio just west of Cleveland and on the lake. I think like you, our summer heat isn't hot enough to kill off the poa annua. the poa annua pressure in the spring and even right now is high. DoyourOwn recommends a PGR to control poa along with pre-emergents. Paul at Prime Cuts has good luck with Anuew PGR at full strength impacting Poa annua and triv.... my game plan is preemergent fall and spring...areas that need seed I'll use Scotts starter w mesotrione. next spring ill use Anuew full strength to see if it smokes the poa as Paul claims.

[@PacificNorthwestLawns]

I tried the Anuew last season. While it did suppress it, it definitely didn't kill it. Hopefully you'll have better luck.

[@SamsLawn]

Hey Nate, man that's a lot of poa, I had hopes that the poa constrictor would work for you, it doesn't seem like it even made a dent unfortunately. If you do start over, I know some people over here who had issues with poa, they used a sod cutter to renovate their lawns. That way they got rid of all those dormant seeds from the poa. Killing it off with roundup wasn't working, as soon as they seeded the new lawn, the poa was there instantly, so taking away the top layer of the lawn entirely and starting over with fresh new soil without weeds seems to do the trick. Just a thought. Following along and keeping my fingers crossed whichever route you take mate.

[@PacificNorthwestLawns]

I've actually considered renting a sod cutter and doing just that.

[@shtnrlse]

What if you were to glysophate your yard now a couple times, and do it again before a late fall seeding? Might wake the seeds in the ground up.. I read somewhere those seeds can stay dormant for up to 4 years.. Good Luck

[@PacificNorthwestLawns]

I actually am going to glyphosate it this week and continue to up until I reseed it in late August. I don't expect it will solve the issue 100% but if I can minimize the Poa Annua as much as possible now, it'll be that much easier to manage later.

[@jeoffbenzos4959]

Any updates on tackling POA? Trying to decide how to deal with it. Sod cut it out or glypho with tenacity when I reseed, or just splurge on Velocity, or maybe some other concoction.

Thanks for sharing. I have the same problem. I have a very small front yard, less than 1000sq ft. I am strongly thinking about killing the lawn and start over

[@PacificNorthwestLawns]

It's not just about starting over. There's also a timing of a pre emergent soon after the renovation. I'll be covering that later this season. I forgot to get it done 2 years ago, that's why I had it come back with a vengeance.

[@jegrand]

Thanks for the video! What’s the best option for spot spraying poa anna? I have a few small spots the backyard. This is very timely as we live a few miles in Camas and notice poa starting to crop up the last few weeks.

[@PacificNorthwestLawns]

Simple spot spraying would probably be glyphosate or hand pulling it. Seeing as overseeding season is almost here, you could do either and just seed the spots in mid August.

[@jegrand]

Thanks for the reply, appreciate it! What pre-emergent for POA do you recommend for this area? Is Prodamine best to apply when our soil temps get near 70? One or two applications?

[@PacificNorthwestLawns]

@@jegrand You can use Prodiamine or Dithiopyr. Yes you want to apply it before the soil temperatures drop below 70*. You can use something like www.greencastonline.com/tools/soil-temperature to monitor the soil temps in Camas or the Yardmastery App. You can do one application at a 6 month rate or better would be do two applications about a month apart at a 3 month rate both times.

Hi Nate, I used the same. vintage of Yard Mastery MySoil Double Dark seed 2 years ago for an overseed in my front yard. I don’t notice many weeds. Do you think the POAs were from the seed or were already present in your soil?

You talk about it growing in July. Yes of course. The killers don't kill the grass. They are only a pre emergent. There is no need to kill your lawn.

Poa can make a great putting green, sounds like you’re 80% of the way there 👌…for real though, what a pain! Looking forward to the Reno, should look awesome!

I think most of the golf courses around here have resorted to just that. Myself, I'm not going to give in so easily 🤣👊🏼

[@Nvent1]

I planted fescue this fall, now i seem to have poa anuua and trevelis invading. I did research and found many golf courses have poa for their greens. I spent about three days picking it out(trying to go organic) now I'm figuring since i just probably planted a million poa seeds I should skip reseeding with fescue asap and just make it like a golf course? I'm in the PNW Clark county What do you think thanks

[@PacificNorthwestLawns]

You didn't plant poa seeds. The stuff is in every yard here in Clark Co. The process of seeding or overseeding just helps dormant seeds germinate. You can just let it go like 99% of the homeowners around here. Golf courses primarily use it on greens mowed at a fraction of an inch. It's not the same as most homeowners.

[@kenny4540]

Nvent, I live in Snohomish County (similar climate to Clark County). Two years ago I had lots of poa, both annua and trivialis. I treated with a blanket spray of tenacity (I know Nate is not a fan) and spot treated with glyphosate. Overseeding in the spring and fall. Now, at the beginning of this third season I don't see any annua (yet) and only two small patches of triv. I will treat with blanket spray with tenacity, spot spray with glyphosate and overseed in May. Every year it looks a little better. This program does not allow for use of a real preemergent because I am overseeding in the Spring AND Fall.

[@mikemeskel]

I think Ryan Knorr said that if he lived in the PNW, he’d just say “screw it” and rock a lime green all poa annua lawn. There’s nothing “annual” about it around here. It grows all year and even seems to have a wider range of time that it will germinate.

[@PacificNorthwestLawns]

I agree, this stuff seems to continually germinate regardless of the time of year around here.

[@driximus]

If we didn't random heat waves that killed it off I probably would.

[@dandylawnandmaintenance4407]

The struggles of PNW lawn is real. I am always hesitant of seeding lawns for clients in our area cause sometimes you never know what your going to end up with.

[@PacificNorthwestLawns]

This poa annua has been here since I bought the house in 2014. It's just a pain in the rear to contain.

[@Joshgats20]

I wouldn’t kill it and re-seed because you will have a massive amount of poa annua seed still in your dirt. If you do maybe kill off, scalp, water for two weeks, kill off again. I have been able to kill poa annua selectively with T-zone which is off label. In the late spring, water your lawn real well, to make sure the desirable grass is healthy Ann’s stress free, wait for a cool evening and put T-zone with a non ionic surfactant (even though the label says other wise) in a tank mix with the poa constrictor. That combined with the warmer weather will knock it out in 1-2 apps. Try it now in the fall, what do you have to lose?

[@PacificNorthwestLawns]

Well my seeding window is in Late August. I already wiped ot all out and reseeded. Pre emergent goes down this week to help limit any from coming back over the winter.

[@beautyDeleon]

Spectacle g pre-em

[@Tundra_Guy]

Only way you're going to get a handle on annua is to use Pre M in the Fall each year before it starts to germinate again. Problem is you won't be able to seed if needed. On the bright side, annua is easier to control than triv.

[@PacificNorthwestLawns]

That's why I'm seeding early and getting a pre emergent down not long after germination of the seed. It's not impossible but difficult. I've actually had better luck with the Triv. That's all about the right timing.
