- Are you dealing with crabgrass or is it something else?
I'm sure this has been a common question for many homeowners over the years when looking at an issue in the lawn. Today I'll go over the stages of crabgrass and what it looks like but also some other common issues that might be mistaken for crabgrass. Things like poa annua, rough grasses like clumping tall fescue, and nutsedge can be other issues disguised as possible crabgrass.

Online resources are good for information. But, nothing like a book to flip through. I enjoy that book too. Thank you for the valuable and proven ways with referencing weed control.
Ryan,
I just checked online concerning the booklet from Purdue, and it stated that it was unavailable at this time, although if one wanted to download the PDF version, they could do that. Thank you for making us aware that this document was available. I've enjoyed every video that you have posted. My best to you on your land purchase and building project.
I have a hardcopy of that Purdue weed guide. It is ...fantastic... as a guide, reference, advisor, and prescriber. The discussions about different herbicide options for different difficult weeds is awesome. Oh and the tables in the back!
I've been waiting for a video like this to come into my life (Foreigner, 1981)
The app PictureThis is very helpful to identify weeds in your yard. Poa is running wild in New England right now.
Great video Ryan - that book from Purdue looks like an excellent resource. Thanks for sharing!
Great information and video. I have been looking for a good reference book thank you for sharing this! From watching your channel for the past few years. I have a great looking lawn and now the whole cul-de-sac is upping their game. Thanks again and give the dogs pets from me 😎
What great info, Ryan. Thanks for clarifying it. Now I learned what nutsedge looks like. And I have some this year. Darn it.
Thanks Ryan, this weed control booklet is going to be an amazing tool, so glad you shared it with the community, I have been looking for something like this for a long time. Really appreciate it.
Its out of stock!!! :(.
Thanks for sharing Ryan👍
I decided I was going to care about my lawn this year and have been using your tips since early spring. It has been going great thanks for the tips. Still got some time before everything looks great, but by this fall, I think I'm going to have a good looking lawn. Thanks for the videos! I'd love to see some like how to decorate, or ideas for around the lawn to make it look nice.
Cut it taller, besides everything else.
Great video. Been dealing with this very topic👍
We have loved watching all of your videos and they’ve helped us immensely! We’ve been trying to adapt them to Canada as we have so many more restrictions on what we can use. Any additional suggestions for weed control?
Nice video, informative! Thanks 😊
Man, this would've been perfect a few weeks ago! I had a case of nutsedge in my lawn and it was nasty, had never seen it before. I've been through several seasons at this house, and never had an issue until this year. Luckily there's good options to get rid of it. I need to stay on top of using Weed G Gone, and spot spraying.
Thanks for this!
Love that you’ve got Keystone Light in the background 🙌🏾
Thank you Ryan
That book sound great . Something I’ll be picking up. To really understand crabgrass.
i bought that guide 5-6 years ago. Well worth the price.
Skipping pre em for the first time ever this year. We will see how thick my grass really is🤣
Good stuff Ryan. 👍🏼👍🏼
I have had problems with clumping tall fescue in the past. This year is the first year I have had POA Annua. Cut my grass and three days later I noticed part of my yard by the trees that had just sprouted up. POA Annua.
Omg I been trying to tackle this all week. This video has read my mind. My neighbor has crabgrass or whatever it is. It got into my lawn and spread because I had to mow. I'm in Arkansas btw.
I cut a section (same exact section) out on my front lawn twice over the last few years and it comes back, very minimally but it does. I'm almost thinking someone watches me dig up these sections and runs over with some crab grass roots at night and puts it under the soil 🤣🤣 Thanks as always for the info Ryan, wish we had some of those products up here in Canada.
Thank you!
Thanks for this
I have the same book, it’s a gold mind
I did lawn renovation in 2019 (Tall Fescue/Ryegrass) and since then I think I have Poa. Some of the stems are partially red though, why I think it's Poa is it goes away in the summer. Sprayed Tenacity although it's not listed to kill it, it does turn white after about 2 or 3 weeks. But I don't usually use pre-emergent in late summer/fall as my lawn doesn't get weeds in the fall. I guess I will need to revamp that plan this year!
Hammer lawn with Lesco Dimension fall time and early spring. If you are seeding in spring, put down Tenacity / granular mesotrione
Last Aussie 😁. Ryan, great info. 😁
You didn't mention dallisgrass. Maybe you don't get it in the midwest, but we get a ton of it in TN.
Would it be a bad idea to apply another round of pre-emergent 2 weeks after the initial application? Love your content, has been my go to for my northern lawn
Enjoy the videos, lots of helpful info. I’m kind of stuck, got over an acre with red thread. Do I use a fungicide or do a soil test to give the soil what it’s lacking? HELP!
Definitely poa trivialis. It's all over my lawn only after 3 seasons. My lawn now needs to be completely started over. Handle that asap.
My issue after a complete kill off Renovation in the
spring last year is a complete invasion of poa. I did a blue grass and tall fescue blend that looked amazing last season it's now back to complete crap, I want to quit.
I got an absolute minefield of young crabgrass and yellow nutsedge in one of my raised garden beds, since i didn't do a good job last fall of pulling weeds. Just pulled what i could and mulched it, no way to spray. None in the lawn fortunately.
Thanks for this video. I have what I thought was crabgrass but is tall clumping fescue. It really has overtaken my backyard to the point where it’s more tall clumping fescue vs Bermuda, so unsure what to do about it. Would going scorched earth and taking everting down to dirt and resodding be the best solution?
Always enjoy your videos, Ryan. Also...cool shirt! Mind sharing where you got it? -Nick

Man poa annua came out of nowhere and took over my lawn this year. Tenacity seems to be keeping it at bay for now.
Consider Anuew PGR to fight the poa. Doyourown recommends a PGR as part of a poa a
stragedy.. check out Prime cuts on RUclips, he uses Anuew as well
Crazy that some people are just recently having to put pre-emergent out and down here in Alabama, we've had pre-emergent down for three months
It's been a very long winter for some people
Love keystone light. I see you do too. Few on your bench
Amen
@RyanKnorr RightLineEtho 4SC is the generic of Prograss and it's only about $80 a bottle.
thanks!!
I got really into growing and maintaining a perfect lawn and then learning how to grow a great vegetable garden. While there are some similarities it seems like they often go against each other. While I love the look of a perfect lawn is it really worth it? Sometimes I feel like it is like the bodybuilder on the stage pumped full of nutrients just to look good.
My lawn is in northern Va. I have been hard into care of the Saman for the last 2 to 3 years. I have a large amount of the two POAs and possibly barnyard grass along with some other grasses/weeds that seem to be very difficult and expensive teal kill, if it's even possible. Starting to think it's not worth the cost and effort to try and get a really nice lawn.
@@mtnbikerva1 NoVA myself. I agree, I think channels like this show you the maximum you can likely achieve and leave it to you to decide how far you want to go. I probably go 50-60% of the extent that Ryan does, and I’m good there. It would be too expensive to go the rest of the way with my lawn AND take care of my trees, perennials, etc. As long as you don’t have a HOA breathing down your neck, I think you can go as far as you find satisfying and stop there.
orchard grass is one growing right now that looks almost identical to crabgrass
I've noticed a lot of creeping bent grass starting to spread through the lawn. It looks "ok" at lower height of cut, but anything above 3 inches it looks awful.
Currently resisting the urge to spray weeds. I made a plan this year to only focus on thickening turf, soil improvement and root development...
Doing the same. Poa big issue but lawn is thickening up nicely from fall overseed. My focus is strengthening root system
from a nasty army worm infestation last season.
@@thurstonr9929 what zone are you in?
@@zachblair463 zone 5
i have trouble with clover and a creeping vine weed that has a smaller leaf than Charlie
So the million dollar question is, and hint hint this would make a great video, when you have a lot of poa, and NEED to do fall pre emergent, how do you fix the damage/fill in the spots left by dead or removed poa? Long Island is getting hammered by it this year, my local Facebook LCN group is full of posts.
Where in Long Island are you and what’s your Facebook group?
@@chaunceysolomon8120 I’m in Holbrook but the group (not really mine, but local) is the Lawn care nut Long Island. An offshoot of the main LCN group.
Question, so say you see a weed you want to get rid of but you don't use an chemicals do yo dig up root and all or do you just get down to ground level and the put some to soil over it and seed it and rake it in or even use a rider mower to push it firmly into the top soil?
Ryan, it would be awesome if you sold these through your website so we can support the channel!
My lawn is in northern Va. I have been hard into care of this lawn for the last 2 to 3 years. I have a large amount of the two POAs and possibly barnyard grass along with some other grasses/weeds that seem to be very difficult and expensive to kill, if it's even possible. My neighborhood is becoming over run with the same weeds. Starting to think it's not worth the cost and effort to try and get a really nice lawn.
I have spent WAY too much time reading, watching videos, talking to local Nursery, Va. Tech soil samples, Va. tech extension folks...
Purdue, Kentucky, Pa. And multiple other university lawn related info.
The broadleaf weeds seem to be easy to control.
I have used: mesotrione, triclopyr, fenoxaprop, 3 ways, prodiamine... also lime and fertilizer.
Poa Annua surprised me this year. A whole strip of weird seed heads. Not much actual clumps of the grass to speak of. Very tiny plants with prominent seed heads.
You can try to cut out the plant if you see it early as well.
@@philipsmashmouth8782 I was told to use Tenacity. At least 3-4 applications to kill it. I just did some spot spray in my backyard to see what happens.
I have it throughout my lawn this Spring. Never had this kind of issue. I don’t want a bunch of brown spots so doing test spots in the back yard. Honestly, since the poa dies anyway once temps increase, I’m just going to keep seeding those areas to crowd it out with my new grass.
@@philipsmashmouth8782 Do not low cut- shows more. Let your grass grow high to crowd it out.
@@philipsmashmouth8782 Trust me, I know. Very OCD about my lawn and you better believe it spreads!
My reno came in beautifully last fall so it breaks my heart to see this poa. But my lawn is pretty thick so I’m hoping to crowd it with my fecue/kbg. I’m doing a suggestion made and throwing seed on the areas.
@@aguyandhiscomputer wild violet is EASY to get rid of. Triclopyr +mesotrione/tenacity + fenoxaprop + 3 way and it is gone. The triclopyr alone may well get rid of it.
Thank you for this. I’ve got a new weed popping up everywhere and I can’t seem to nail down what exactly it is. My tenacity effectiveness seem to be hit or miss. 🤔 and I’ve also got a lot more poa than I’m used to seeing now that you mention it.
I hate Poa Triv!! Sprayed a large patch last year, reseeded, looked great and then this spring I had new patches pop up.
When are the bloopers?
Doesn't Mesotrione or Tenacity handle post emergent control on Poa Annua? I just put some Mesotrione down yesterday.
I need some guidance. I put straw on a newly seeded lawn last year. Purchased at a local farm. Our yard is now full of wheat. What can I do? Starting over is not an option. Please help!!!
Hey RK, do you think there's any benefit to spending more money for UMAXX vs. Andersons HCU 44-0-0?
I just bought a house (minnesota) what would be a solid video idea would be where to start I never had to care for my own lawn before and it’s loaded with dandelion and clover and a bunch of random weeds, but like where to start what to go after first when trying to transform a lawn from all weeds and little grass to perfect lawn
Already made that video 🙂
The book says it's unavailable for purchase, at least single copies. Don't really want an unprintable pdf file.
Does pre-emergent have any impact/suppression of poa trivialis? Thanks for the video!
Prodiamine in the fall will help control it in the spring.
@@koolmaaan imported topsoil and aerating/overseeding in both spring and fall the last couple years haven’t helped. Grass is thicker than ever but also more poa triv than ever.
I'd like to see a video on the amount of $ you spend on chemicals in a year. I have about 9000 sq ft of grass and put down 30 lbs of fertilizer 3-4x /yr, spot spray dandelions with about 2L of speed zone mixed from concentrate, 1 application of pindee 3.3 for crabgrass (about 330mL worth) about the time when the trees are budding which is about early May, and 1 application of generic merit 75wsp in June for grub control. I feel guilty putting that much on our lawn.
Omg your reading my yard's mind. I have nutsedge too.
I've been using Tenacity in the Spring and Dimension in the Fall and my Poa Annua is slowly being taken out.
1+ for this. Planted new perennial rye, didnt fully come in until October, was screaming green mid December in CT. Put down dimension and don't have much crab or poa. Put down some tenacity and starter fert and filled in bare spots with seed.
@@Dsaubt Exactly how I did my regrade and reno a year and a half ago. Still fighting some clover, but should be an easy fix after the Spring patch repairs grow in. 👍👍
Huge issue with seed head. I cut the grass a few days ago but it’s growing again.
Maybe bag your grass for a bit so you can collect the seeds.
Typical thing in spring. Completely normal
Just tried to order one of those books and they are all sold out. You caused a run on them!
Ryan, is there a crab grass pre-emergent that can be applied while seeding and is safe for kids that you would recommend?
Safe for kids, probably nothing. Tenacity is what you need.
I checked out Perdue's website and the physical book is unavailable. I wonder if they're making a 2022 iteration.
PDF is available currently but yeah maybe they are updating for 2022
I'm looking for a book like that but specifically for the European market as I fear many of the chemicals mentioned in the book will be illegal to use inside the EU. If anyone has any info I would be much obliged.
Would Tenacity work on the weeds you have discussed in this video?
Not necessarily. It's usually best mixed with something else depending on what you're targeting
@@ryanknorrlawncare Thanks for the quick reply. I was going to mix the right amount of Tenacity, surfactant, and blue dye, with water.
So you’re saying trying that might now solve my problem?
I have a lot of Poa this year. Waiting for the heat to burn it off. $520.00 for Prograss…wow! Interesting product, but after reading the label…very dangerous to humans if used incorrectly.
I paid the $12 to download the PDF but never received or got a link afterwards.... anyone else have this issue?
My prob is annual blue grass. So annoying. Can’t kill it with my tall fescue
Can't even create an account with the store to buy the book and PDF, you would think they would treat a Purdue grad better 🙂
I am going to refer my friends and neighbors to this video. I get asked constantly in the spring how to get rid of their crabgrass. I tell them, "I don't even need to look at it... It's not crabgrass."
You didn't know if it's not dandelion or clover it's crabgrass? Lol
I wish my lawn just grew ryegrass and no weeds could ever creep in 😂
Where do I get the shirt you’re wearing?
www.kujo.com/backyard-t-shirt
Dang, book is already sold out. I'm unlucky enough to be dealing with poa annua in the front and quack grass in the back and a whole bunch of other things that I haven't even identified yet
you can also get it in pdf form
@@ryanknorrlawncare I did see that! I think I'll wait for the print option to become available, nothing beats being able to flip through a book
I've always had good luck just pulling nuts edge. Grab the stalk at the base and pull 95% of time the roots come out, and only have todo this a few times to get rid of it.
That can actually aid in it spreading
@@ryanknorrlawncare it can on established nutsedge, but strands with few leaves won't have the established tuber system to spread, also, but staying on top of it and picking every time see new growth can eliminate small areas.
for Poa Annua, nothing does me right (Bermuda) better than IMAGE ‘Kills Nutsedge’ herbicide 👍🏻
Boom!
Dang I though that powannua (or whatever) was just grass with seeds buds lol.
Where can I get that shirt!
www.kujo.com/backyard-t-shirt
good video. poa annua avalanche this sprin in northeast ohio. i just did a major overseed. despite pre emergent last fall and tenacity this spring at seed and 3weeks later.
poa spread so fast it was choking out the new grass seed. I'm at a loss to explain
Doyourown also recommends a PGR as part of a poa strategy. Paul w Prime cuts also pushes that strategy w Aneuw.
Poa annua is everywhere here in Vancouver, BC, Canada, and our environmental rules don't allow us to use anything that can kill it. It's spreading everywhere and there's not much I can do about it. So frustrating!!!
@@chaddychadderson so many things banned in Canada.....good reason to migrate to the last land of freedom... while it lasts
Man, I feel your pain. Same scenario, complete reno with tall fescue/kbg followed later by fall pre-emergent and nothing but poa annua/triv this Spring. I contribute to aerating the lawn.
My mishap was not applying Tenacity early on. I never had an issue with poa til this year. And it’s every where! A strategy I’m trying that I picked up from another lawn RUclipsr is seeding the areas where the poa is to crowd it out. My turf is coming in nice and thick so perhaps it will work. As the temps increase the poa annua will die back so I’m hoping the new seed germinates in those areas.
Worth a shot as opposed to brown spots in the lawn.
Poa triv is an entirely different problem. I’ll address that in the fall.
@@thurstonr9929..I used Anuew last year and it did slow up the poa. Then pre emergent, 2 apps, tenacity earl spring. I used a seed slicer/overseeder. I wonder if that aggrevated the issue. I applied tenacity again but the flood gates opened so to speak, like a biblical event! I've gone back to some areas and smoked it to start over. Other areas I've hand picked to give the seed a chance. My neighbors think I'm nuts.
@@thurstonr9929 that's a great tip thank you! I'll try it out. I think there are a few things contributing to my issue. Poa is everywhere around here so it was bound to show up, I watered my lawn a lot in the back yard last summer so I likely kept a lot of the poa alive for longer than it should have been, and now a really cool spring. I plan to limit my watering this year and hopefully I can manage to grow some new KBG while the poa dies out. It'll be tricky. I was so frustrated a couple months ago I almost tore out my entire back lawn.
At 3:46 Too bad that Purdue book isn't for sale anymore, but you can download it for twelve bucks. Probably need a color printer I would think.
👍👍🌱🌱
My neighbors lawns are all exploding with POA, I don't have any
what is that shirt your wearing?
www.kujo.com/backyard-t-shirt
Boiler up!
What is the weed on the cover? Chickweed?
Poa Annua is from the pits of hell
Great video and right to the point without all the video intros and cinematic edits. I know your into video and music but please do more like this.
I have quackgrass, I’m screwed
Sorry :(
@@brewersfan2112 not so soon Jr look up ornimec 170.
no way! Its all TTTP!
You must be a mind reader because I was just wondering what was going on with my grass and the type of weeds I need to treat
In Europe all these products are illegal. I have to grab my weed pull tool and go crazy instead of these fancy products haha
Waiting on the organic option. I don't disagree with my spouse on that but I'm ready to go nuclear on the lawn but seems we will stay with more weeds than lawn.
Dig out
A printed copy is no longer available.
We can put men on the moon but we can’t create an Herbicide to kill poa ?? Very disappointing !!!
Skol go Vikings
