Help me ID this plant ......

For the first time, these are coming up volunteer in our backyard garden. Pretty hardy looking plant, I've never seen them before. Definitely not quack grass.

Crabgrass.

Thanks for the quick response. I did some web image looking after your reply and I'd say you are spot on correct. I've heard of crabgrass, and I think up here that name is sometimes used for quack grass, but I now know tht crabgrass is quite different from what I know as quack grass. Quack grass is not so robust and has a totally different root system. Funny it just showed up for the first time ever in our yard and it's not in our lawn (yet).

Used to see quack grass a lot. Roundup pretty much wiped quack grass out though around here.

Cutting your grass pretty long so the dirt stays shaded and is undisturbed is a natural way to prevent crab grass.

Quack grass and crab grass are 2 different beasts, even in Canada! Crabgrass is an annual while quack( or twitch) grass is a perennial. Also, there are 2 different species of crabgrass,crabgrass and large crabgrass. As the name implies, large crabgrass is considerably larger than regular crabgrass. Both are mid to late season weeds that emerge after most other weeds. Very prolific seed producers!

More good info ... thanks Brad. I would guess that this is definitely the LARGE variety. That one I pulled and washed the dirt off the roots for the photo was one of the smaller ones. They were hidden in with the onions so we didn't really notice them till lattely.

Both species have very rapid growth rates. Give them adequate moisture and some warm or hot temperature and watch out! Both put out a very dense, fibrous root system. They can put up a good fight either hoeing or pulling!

Given its size, it looks more like Johnson grass to me.

I hadn't seen it in years. I have three new seedings that that I planted last year that are infested with it fencerow to fencerow. It's not just a few little patches. All I can figure is, it must have been in the seed oats that I planted as a companion crop.

Being as Crazy Horse is in western Canada, I think the chances of it being Johnson grass is very slim.

For Brad and Scooter .... this article distinguishes between the two grass species, as similar as they might appear they are quite different. I would vote for crab grass just based on the roots of the plants we pulled out There are no creeping or suckering rhizome-type roots on our weeds. Pretty good article .... that Johson grass can grow pretty hgh from some of the photos I see on web searches.

Is Johnson grass the same as crabgrass? - Green Packs

Johnson grass is not the same as crabgrass. While both are types of grass weeds that can be problematic in lawns and gardens, they have distinct differences

Had a lawn care specialist tell me if you just let crabgrass grow it will kill itself.
And then he said nobody can ever wait that long for that to happen. He was right

Everyone I know has an abundance of Crabgrass this year.

Hadn't seen it in years...you referring to crab grass or quack grass? I would guess that you are right about the seed oats.

I agree. I don't see a white stripe on the leaves either.

Another thing I'd add is that crabgrass typically stays close to the ground in my experience. Since I've lived out in the country, I haven't seen crabgrass. It was common in the cities. My lawn is simply land that was cleared by others and myself, and then mowed regularly. It's probably only about 50% lawn grass (mainly fescue from the looks of it), with countless other things growing with it. But not crabgrass. The number one outlier is probably plantains. I think a previous owner may have seeded the area around the mobile home that was here with bluegrass, but that's a small fraction of what my yard is now.

I still see Quackgrass around the farm and am glad to see it in some of the places I have found it lately since it has a good root structure for sod waterways . I hate that Reed Canary grass we have acquired in the last 15 or so years. IT is worse than Quackgrass and even cows didn't like it if it got taller. bottom side of the leaves were like sand paper. Looks something like Bromegrass only taller and courser. Brome teds to have a bunch or clump like base unlike Quackgrass. Crabgrass inot much of a problem in the filed and a real pain in the garden. I think I'm going to after things get donew in the garden burni t down with some roundup or other contact herbicide to help clean it up.

Well over half of my 80 acres is Reed Canary grass (it's most of my flood plain acreage.) It will get seven feet tall in a year it likes the conditions of (like this year.) I don't fight it, mowing the lawn keeps it from encroaching. A previous owner grew it for hay.
