RoundupConcentrate Poison Ivy Plus Tough Brush Killer, 32 oz.

This saves me a lot of money instead of buying the already diluted one. Also it works like a charm! Kills just about everything it touches. Except winter creeper

I moved into this house nearly two years ago to find a very pernicious vine growing in two beds: Houttuynia or Chameleon Plant. It is also known as fish mint. It takes over all other foliage and creeps out into the lawn. I have tried to kill it with many products, all to no avail. I tried digging it up - but it grows laterally, and the roots are everywhere and they run deep. I bought this, since it's supposed to kill poison ivy - another stubborn vine. Hallelujah! It's working! I suspect it will take a season or two to finally eradicate this, as the roots continue to send up new sprouts every few days. But I will keep at it, spraying all the new growth. By the way, I'm using this full strength and being very careful to only hit this horrible plant (which has a weird odor to it - the dog loves to roll in it - yuck). Yes, it's pretty - but it's pretty obnoxious as well. Anyone trying to fight this invasive species - here you go! You have to stay on top of this and be patient, but I think after two years of fighting, I'm now making progress! Thank you Round Up!!!!

I used this primarily for the wild invasive honeysuckle that covered a great deal of the floor woods near the flower beds. Honeysuckle will choke out small trees, bushes, and anything in its path. The only way to get rid of it is to pull it out completely by the roots. The job was entirely too big to do that. This stuff is amazing. I put it in my handy pump sprayer and apply it when it is good and hot. Within days the honey suckle turns brown and my young trees are free to grow tall. This stuff is also great on wild blackberry, poison oak, poison ivy, Virginia Creeper plus invasive Japanese stilt grass plus pretty much any woody stem weed.

At first I didn't think this was going to work. It took several weeks before we noticed a big difference in the poison ivy, honeysuckle and greenbrier that we sprayed. I'm used to seeing more immediate results. But now after several weeks there is a big difference. It seems to be very effective. It just takes time.

UPDATE: So, I sprayed my yard close to two months ago, give or take. I live in Vegas, with a rock yard that was improperly lined when we bought the place. I think they just rocked over old lining. I have had my yard trenched to replace the main water line twice and all that loose desert dirt has encouraged a "river" of weeds all the way from the vault to my house that I pull twice a year, as well as the condensation pipe from my AC that drains next to my garage creating a nice moist spot for weeds to thrive in the narrow planter bed. And now that monsoon season is about to kick off, it will soon be a recipe for disaster... except?I strung up a mister system in my front yard tree because I had been working out there in 118 degrees, hack sawing on aluminum trim at odd lengths and angles and needed the elbow room, which after 105-110 degrees, you don't notice the difference except ya sweat more, but it annoys me, gets in my eyes, burns, etc., but the misters really did the trick. In the shade of the tree, the mist doesn't evaporate and actually waters the ground around the tree. Puddles on my table, too. Another place for weeds to thrive is where it's cooler like in the shade during the hottest part of the day.I must say, 2 months and not one single foxtail, goat head vine, or other random weed to speak of and the old weeds died so hard they turned to dust and blew away. 😳 I'm gobsmacked and take back every word leaning toward unimpressive. This stuff rocks. Patience is not my best character trait, although having kids will force you to learn, but she's 21 now, work and school full time. I got nothing to gripe or be patient about these days. Lol If you have no problem letting the dead weeds do what dead weeds do, this stuff is effortless. Just mix as per the label and spray those sucker's and forget about them like I did. Might take a couple weeks to fully realize the desired effects, but 🔥 hot damn! I was shocked when I realized how CLEAN the yard appeared when it occurred to me to observe the results. I'm keeping this stuff around. No more pulling baby TREES with roots long enough to tap into the water table anymore and all the fine barbs that my gloves just don't protect against cuz I refuse to spend more than 3-5 bucks on garden gloves. Lol *shrug* +1 star. Well earned. 5/5It was a bit lackluster on its performance, but it could be user/buyer error. I expected instant wilting. Not really, but damn near. It says within hours! Bottom line, ding dong the weeds are dead. Some little piddley weeds took days to recoil at my poison! At least now I can take a torch to the rock lawn, get all the little dry sprigs, and call it a season till monsoons show up. Crap, I guess I should hit the back yard, too.... A girl's work is never done. I have a dang tree weed back there that spits cottony, feathery crap. That's what this stuff was made for, no? It will be the ultimate test. If I remember, I'll update. If it does what it's supposed to, I'll up my rating, too.

Spray lightly with this product when it's dry & no rain is in the forecast. Allow it to work over a couple or three days. If the unwanted weeds/brush hasn't turned brownish, reapply. IT WILL KILL EVERYTHING THAT'S SPRAYED SO BE CAREFUL AROUND YOUR PLANTS THAT YOU WANT TO LIVE. I think it's a little pricey but I've tried other, less expensive products that claim to do the same job and have had terrible results. Buy the Cadillac of weed killers....Roundup.

update 4/29/24: I didn't have to do dig out any new bamboo after the application of roundup last year, no new bamboo shoots came out on my side, also I think many bamboo on my neighbors' side are now dead because the roots are all connected together. I'm very happen about this product.I bought it to control bamboo growth coming from my neighbor’s yard. The instruction says cut the stem and pour the concentrate into the freshly cut stem, which I did, I also dugout a lot of roots and pour the roundup concentrate to the fresh cut. It took a whole winter to show the effect. Coming spring, I can barely see any new bamboo shoots coming out, and the bamboo in neighbors yard, although I didn’t do anything to them, the leaves started to turn yellow. I don’t think they are dead, but they definitely not going to expand to my yard that fast anymore. Great product, this will be my go to product when I need to control bamboo growth.
