What exactly do you mean by "stinging grass"? Is this just something that you're allergic to? If it's poison ivy or oak, you need a brush killer with triclopyr in it. If it's a type of grass, it will probably need sulfentrazone, or you might just have to bite the bullet and use roundup and have some dead spots to heal. You can't get MSMA anymore; that stuff killed all sorts of grassy weeds in bermuda without hurting the turf.
If so, that's stinging nettle, and you can kill it easily with a spray of Trimec or a weed and feed fertilizer with Atrazine or Penoxsulam. None of those chemicals will harm healthy Bermuda, although the label for Atrazine says not to use it on Bermuda. Just make sure to put it out before a rain or water it in well if you use a weed and feed fertilizer.
If you want to spray, and can spot treat, go get some 20% acetic acid vinegar from lowes or the local garden shop. dilute it 1:1 with water or stronger (effectively a 10% concentration or more) add a teaspoon of Dawn dish soap to a one gallon mixture and spray.
Strong vinegar can handle broadleaf weeds like this no problem.
be sure to put down a pre-emergent herbicide like barricade to prevent new seeds from germinating.
I can shed some light on this subject. Most or should I say alot of people do not know what stinging grass is. It is NOT bull nettle. The ONLY WAY to get or even try to get rid of this stuff is dig it up place in a garbage bag. If you spray this with ANY KIND of weed killer, broad leaf killer,It will die BUT when it gets dry and dead it will re-seed itself. If you happen to have any kind of livestock they love this stuff when it dies. In which they will just spread even more. Dig it up and throw away. Do not burn as this will not help either.
I took a picture and need to upload it. It does not look like those pics. It spreads like a creeping weed not growing tall. At least not that I know of.
We do have horses and they will not touch it. We are getting goats soon though so I am wondering if they will eat it because I heard sheep will.
I know it is in Kingwood too because we had some in our front yard. The regular Bonus S killed it but it also killed all the Bermuda too and I don't want to go through that again. I want to keep all grass that horses eat.
My daughter pulled up a bunch today with a shovel and gloves while I cleaned stalls. She was not happy.
goats will not eat it. If you spray it and it dies they will eat it then in which they just spread it even more. Last year I sprayed a whole lot and killed off everything . Guess what its back. With the dry spells we are having and the winds like they are it just blows and seeds everywhere.
YES, This is what I refer to as stinging grass. Like most of the comments say. Best is to dig it up and dispose of it. It reseeds and is VERY PAINFUL. I had a friend and her little one fell into a patch of it with short sleeve and shorts on. This poor child suffered with the whelps it left.
I am not sure if it grows tall or not because we never let it get to that point. Basically, I just want it GONE.
It is painful and the only thing I know to do is cold water. My kids cry with it.
Now the stuff that is tall we happen to have in an old tomato planter and I accidentally touched it while moving the planter the other day. It felt like I was attacked by a swarm of fire ants. It wasn't enough to make you cry but I was only stung in 3 small spots. I imagine if I had touched it with a larger area it would have been awful.
The problem is we have land. The back yard is only about 1/2-3/4 of an acre and that is my main concern because the kids play there.
However, I also want it gone out of my pasture and front yard because the horses won't eat it and I don't want it taking over everything.
So in a perfect world, I would be able to put something on it that would kill it and not the other grass around it. And if it's not too much to ask, I'd like it to be something that won't harm animals or people.
Ok, seen that stuff before. Note: in my googling, apparently washing with any high-ph solution will help with the burning sensation: lemon juice, vinegar, etc.
Organic Options for acute treatment: - Spot/area treatment 10%+ vinegar solution w/ surfactant (i.e. dawn dish soap) will burn the stuff out of the ground, the grass will get hurt but bounce back. Pros-cheap as he]], cons-a pain to do for large areas - Bakingsoda with cinamon (that's what those "cinnamon" crab grass killers are). don't know what the Cinnamon does, but the baking soda basically causes the more shallow rooted weeds to dry out and die. Cons-can be expensive and may be less effective. pros-will only discolor otherwise healthy st. Augustine.
InOrganic solutions: -nearly any broad-leaf weed killer (go for granular and don't over do it) - one or two time treatment with a weed and feed fertilizer(I never support the use of atrazine, there are products that don't have it, use those)
To keep the stuff from coming back: 1) after treatment: raise the deck on your lawn mower as high as it will go. (TAMU recomends st augustine be kept at 3-4 inches tall for optimum health). Ultimately the best defense is a healthy lawn. Mow to the proper height and care for your soil ecology. If animals keep the grass chewed too low... no solution for you :/
2) regular use of a pre-emergent herbicide Organic: Corn Gluten Meal (bonus, its high in nitrogen and offsets some of your other fertilizer needs... but it can be pricy.) InOrganic: Barricade from fertiloam (I think). Very effective.
the bad news, seeds from weeds like this can survive for a couple of years in the soil and germinate after you think you've eradicated it.
That's what I'd recommend, but if you're in the area and want something more "hands on" dig some of it out, put it in a plastic baggy, and take it to Michael at Kingwood Garden Center.
JCitrus- does the weed and feed kill Bermuda, too?
most do. have to check the label.
Scott's Bonus S or other weed and feeds with Atrazine as the active ingrediaent are NOT labeled for Bermuda, although I know a lot of people around Dallas that use it in their Bermuda with no problems. Lowe's has a brand of weed and feed with Penoxsulam as the active ingredient called Sta-Green that is safe for Bermuda. Penoxsulam is also MUCH more effective than Atrazine on Virginia Buttonweed. I had a yard full of buttonweed two years ago, and it's completely gone now. Penoxsulam isn't as effective against dichondra as Atrazine, though, so I'm going to spray some Atrazine and Imazaquin for the dichondra tomorrow.
Freak do you know the official name of the stinging grass weed I have in my yard?. When we lived in KW we used the Bonus S and the lawn there was half Bermuda half SA. (Tried to get the landlord to resod, but he didn't, sorry KW) Anyways it did kill the stinging grass but the Bermuda too.
I m just wondering the best solution because the issue is that we let the horses graze in the back yard sometimes at night so we don't have to mow. Rather pick up horse poop any day than mow. So I am guessing the vinegar is still the best bet.
You guys have all been so informative and I really appreciate it.
Nope, not sure what that stuff is exactly. It's not Stinging Nettle (Urtica dioica) or Bull Nettle (Cnidoscolus texanus) but any good broad-leaf herbicide will knock it out. Try the Sta-Green with Penoxsulam, and then spot spray with a product that contains 2,4,D; 2,4,5,T; and Dicamba. Jump on it fast before it can go to seed.
Fab, How many horses and how much land do you have? Once you've treated this outbreak (however you do it) and gotten on a pre-emergent herbicide cycle, do you have enough space to put your horses on a rotation? I've been seeing some stuff on holistic management and it's put a bug in my brain is all.
Yes we can rotate the horses. Currently there are two pastures is you count the back yard. DH is working on fencing the front and two sides so that will be a third pasture. Plus they are stalled at night with hay.
The people who previously owned the property completely remodeled the house but were not animal people so they did not care for the land as well as we would have liked. It is much easier to maintain something that has been maintained than to make a turn around, but it is what it is.
In the next couple months we plan on getting goats for milk and butter so they will help the weed problem as well.
Fab, have you ever heard of Joel Salatin ?(not that you should do what he does)
If you're interested you should google him and his polyface farm videos. you may not buy into his whole shtick, but you might want to look into it. I've seen some third-party support for the land management side of what he does. that ultimately might be better than what we've recomended above for long term control of undesireable weeds.
Yes we know who he is. Dh is in the process of building a mobile chicken coop. We can't free range because of the hawks and coyotes.
We are trying to go as natural as possible which is another great thing about goats.
Our back yard and front/side are all mesh so coyotes can't get in. The back pasture has barbed wire on two sides and the other two are mesh. Once DH finishes the front he will do horse wire mesh on the back pasture. So eventually the whole thing will be safe for horses, dogs, and goats, just not chickens because of the hawks. We are also considering incorporating rabbits but if we do it will not be this year, maybe next.
