| I don't want to kill the Prickly pair. What I am trying to do is establish prickly pair along the outside of my fence along the roadside.
I am having a hard time getting it to establish because it keeps getting overgrown by weeds. I am not an avaid cactus guy, but as you all know it's pretty difficult to weed around a cactus. What are your thought on getting alot of this cactus established? I got all of this prickly pair from a hotel that was being torn down, I just took my shovel and cut pieces off. |

| since round up kills just about anything I would say it is not safe for your cactus but I am not expert by any means. |

| I don't think it will kill it. Have you considered a pre-emergent? I'd use an early weed control, then I'd mulch the area immediately around the cacti. Josh |

| GOOD, I have heard people say theses cacti can be a nuisance, but for the area I want to plant they would be great. This is an area facing the road on my privacy fence. This area is narrow and hard to mow or do anything with including water so cacti should be a good addition. |

| It's it a set amount of area you could use sheets of the weed-prevention carpeting, cutting out holes for your Opuntias' joints that you're rooting. It's a little time-and-labour intensive, but it will knock out the weeds and has the benefit of being green. Of course, there are drawbacks to this, mostly the expense and time, but we're spending your money, right? Really, I'd think the weed barrier sheeting might be cheaper in the long run. Another thought is to sheet of certain areas around your cacti. |

| I don't believe roundup will kill the prickly pear cactus. Cactus and most other succulents have a waxy coating that doesn't allow them to lose water easily and thus doesn't allow stuff to penetrate their skin. I have used roundup on hens & chicks and sedums that got inundated with weeds. I tried not to get it on the hens & chicks but I know I did. Killed the weeds-didn't seem to hurt the hens& chicks. It may have stunted them a bit but they outgrew it. I was using the stronger stuff for poison ivy. I wouldn't do it more than once a year. Try a few plants--wait a week or so. See what happens. If they seem OK after a couple of weeks, do the rest. Happy Cacti! |

| I waited a few days for more legitimate answers to be proffered. In the high deserts of the Great Basin there are waxy plants that RoundUP will not kill if used as directed, the liquid just beads up and rolls off. |

| wouldnt the round up also get in the soil an to the plants roots? |
|
| To kill prickly pear it is recommended that either undiluted glyphosate(Roundup) be injected into the flesh or else a spray of 1:10 dilution is used. The dilution needed to kill weeds is far, far less than that. So you can spray away. * Horrible things though, couldn't you use a nicer succulent/cactus than that? |
|
| Round up kinda killed mine. I say kinda 'cause it looked completely dead but months later it sprouted new pads. (my prickly pear was the variegated kind, tho) |

Well they were FREE so that is why I choose them. I am trying to fill in an area between a privacy fence and the road. This is a narrow area hard to walk and weed so I plant on Cacti and Pampas grass and Yucca, Basically stuff that is no maintenance and you can't kill. I find YUCCAs from time to time cut down on the side of the road and I grab them, I also got a few from my neighbor. Thanks for the reply. |

| Prickly pear is an aquired taste. I am on my 35 variety of opuntia/cylindropuntia. There is no reason to shy away from them. They are not for the timid. |

| "There is no reason to shy away from them." Well there are the glochids! ;) I was just thinking they're not the best plant to have if there's human traffic going by. Occassionally at fruiting time I might overcome my timidity to get a few fruit, especially the red ones. Yum! It's a pity though - even they have glochids in them. |

| I used the standard dilution of Roundup about two weeks ago for a weed problem in my Opuntia/cactus bed. It didn't seem to harm the Cacti in the least. But the succulents are a different story. Sedums don't like it. Sempervivums don't either. Didn't try it on the Orostachys but I assume being closely related to the others that it would finish them as well. Surprisingly, no damage on the Delosperma...but wouldn't say that's a 'go' either. I used the standard Roundup. I would avoid the newer, "Extended Control" version. Just my experiences... Dave |
