I agree. RoundUp it. You can use a small paint brush as Leslie suggested. Snip it back so it's short, paint it, watch for new growth, paint it, repeat.

Thanks for the comments! LeslieM, that is a riot about the grass coming in and growing under the bed! I can believe it. :)
I had hoped not to have to use the RoundUp, but that does seem like it might be the only thing that will work. I'm so sick of bleeding when I try to clean it out!

" Snip it back so it's short, paint it, "

NO!!!! You want to apply the glyphosate to the WHOLE plant, not a stub, so as much as possible is absorbed. Paint the WHOLE plant, wait a couple days, then clip it for looks.

If you can cover the plants you want to keep with paper bags or plastic cups, spray the grass, wait an hour or so then remove the protectors.

Well, I'm pretty sure that is what I read on the label before using but I don't have a label handy at the moment to double check. So, ddiverblue, check the label before applying. :-)) Also, I've used those accordion fold windshield sun protector thingies to shield when spraying but that may be too large for your purposes. (lazy, no need to shout. My goodness.) Good luck at any rate.

You would water it real good to get the Bermuda all happy and growing well; this includes hosing the Bermuda dwon to remove any inhibiting dust present. Then paint it everywhere you can reach with Roundup a couple of days later without contacting the plants you would like not to kill. As much as possible in the early morning at this time of year to let it absorb. This will uptake the roundup and distribute it to every cell in the grass. Then wait up to a couple of weeks while it does. This sounds like a pain in the arse to me.

I'd spray PER DIRECTIONS with Grass Getter mixed with a surfactant ("Herbicide Helper") to ensure contact and adherence. A little goes a long way so I'd order the 8 ounce pack, make up only as much as needed. I'd spray sunset. May not have been tested with succulents and cactus (tested OK around Barrel Cactus) though there is no reason to suspect they would be effected by active ingredient
sethoxydim (POAST). I would still try to spray just a small test area first to see if any effect on your desired plants is noted, also avoid the crown of any cactus no matter what would be good practice in my opinion. Note: This kills grasses, not "nut grass" or weeds so eliminating Bermuda may make room for weeds. I'd consider mulching the eradicated area with decomposed gravel or other rock mulch.

Thank you all for the hints and tips! I've never heard of the "Grass Getter mixed with a surfactant ("Herbicide Helper") I'll have to check that out since I do have quite a grass problem despite having no grass for so long.We are traveling right now, but I will do it as soon as we get back to AZ.

Good post, as usual Powell, thanks for the info. I've used Grass Getter before, the surfactant can be just some liquid dishsoap to help the herbicide stick to the grass. You will need to keep repeating the application until the bermuda gets tired of the fight and gives up. ;-) I had such an invasion of bermuda around a pretty yucca plant that I finally just dug up the plant, replanted it elsewhere and solarized the soil. That worked well, I've put another yucca plant in there and am growing tomatoes in that garden section as well.

Grass Getter is a bit pricey and it's stinky. I used latex gloves to keep the odor from my hands. I found the product at Ewing's.
