Here is a field of chufas made in August. Notice how the plants grow in bunches.

Additional pictures solve the mystery. It's yellow nutsedge. It was already in the soil and it took off when you worked it. You probably had some chufas growing there at first, but the nutgrass had taken over now. I can show you fields on my place where the same thing has happened, despite me fighting it best I can.

This is what chufas look like when pulled up. You can easily see the difference in the two plants when you pull them up.

Riverwood sent me several more pics; here is the one I think looks the most like chufas:

It's really hard from that picture to say that they definitely are not chufas, but all the others and what you have posted make me believe that it's yellow nutsedge, or nutgrass as it's commonly called. Nutgrass produces tubers just as chufas do, but it is unusual for me to see as many as in the above pic. One thing is apparent - you have much better soil than I do. I can't even get nutgrass to look as healthy as those plants.

You say it's been 2 years since you planted the chufas. They will regenerate, but I have to work hard to get them to do it with a decent stand. If it's been 2 years and you haven't planted more, then all of my experience says you now have nutgrass. All the other pics look like nutgrass, and even the one above had such aggressive rhizomes that I would guess it to be nutgrass.

But there are people with advanced degrees who say they are the same plant anyway, so maybe I am wrong. Your original seed came from Spain, so who knows if it might have developed a gly tolerance over there? Still, I think you just have nutgrass if you have sprayed that much gly and it survived.

It's hard for me to repost your pics unless I save them multiple times. Go to postimage.org and you can post them all yourself. The key is to not register; just load the image and click on Hotlink for forums and you can post all that you want us to see

Here is one of the best pics I have to show the difference. The plant that is in the front is chufa. Note how it had bunched up. That is nutgrass in the background. Note that though the nutgrass is thick, it is just single stems. This growth characteristic is the easiest way to tell them apart in the field.



There are those who say they are the same plant. I don't think they are because they don't cross even when side by side. If they are the same species, it's only in the sense that a timber wolf and a poodle are the same species.

Note the herbicide damage to the chufas, while the nutgrass is healthy.

Here is a pic of a field of chufas from several years ago that was heavily damaged by 2,4-Db. I had sprayed it at 30 days with a quart per acre, and decided to hit it with another quart at 60. That turned out to be a real bad idea, but I got a lot of rain right after this and most of them recovered.

I've damaged chufas with many herbicides, but nutgrass is hard to hurt.

I can have turkeys using other food. I learned early in life after growing chufa that nutsedge will take over. My hats off to y'all that swear by them. I'll grow proso millet, sorghum and other small grains before I grow that invasive SOB again.

I've got no experience with chufas, but based off of yalls comments, do yall think there's any chance sedge nuts are being mixed in with chufa seeds?

Thanks for posting pics Preacher. Can someone please type a little bit slower and explain the pic posting again. I can get my pics downloaded to postimage and see share to forum and hot buttons but still can’t figure how to connect it to post here. Warning - if I ever figure this out y’all may grow tired of pictures of my bird dog, service dog, granddaughter, and tractors.

You can do all that hydraulic work on a tractor and struggle to post a picture? I don't understand that. I know you have a bunch of pictures and I'd like to see them. It sounds like you have it almost done. When you click on Hotlink for forums it will tell you that it copied. Come to aldeer in the box where you are typing a reply and click there, then paste becomes an option. Click paste and you are done. When you add your text and then hit reply, the picture will appear.


Now tell me how to alter my hydraulics to use a lane shark.

I don't think there is any record of chufas crossing with nutgrass, but admittedly I read that on a pro chufa web site. I've never seen it myself. It's just that nutgrass is already in most fields and prepping the land for chufas turns it into ideal habitat for nutgrass. You could do everything except plant the chufas and the same thing would happen.

So do you have to type in the URL? Or is there somewhere to just click on image? That’s where I always get stuck. Thanks

You don't have to type in the URL. Upload the image and then click on Hotlink for forums. It will tell you it copied if you did it right.

To paste, all you do is click in the reply box. This is the same place that you type your reply, so you know how to do that. Once you click in it, paste will appear as an option, and you click on paste and the URL appears.

A different method using a different link is posted above, but I think just pasting into the reply box is the easiest way.

Think it’s gonna take another rain out like we had last week for me to figure this out. Gotta get some tractor time in now and get fields planted

I'm topdressing tomorrow. Then planting 30 acres fescue for a customer Monday. Plenty of seat time ahead this week too

Good to see you on here Willy, can’t believe you’re planting chufa in that hog infested area you’re in! But, I always have good luck by getting the field ready to plant and letting everything sprout and then spraying with roundup before I plant. The planters stir up a little weed seed but a timely plowing will take out most of it. Of course, I’m primarily battling pusley and that stuffs worse than kudzu. I’m not aware of any pre-emergent that will work.

Yep. Chufas came up good but didn’t turn out quite like I’d hoped. I’ll try em again next season. Think they stayed too wet this summer.

You broadcasting or using a drill or planters?
