I wouldn't try and reinvent the wheel. You can buy a gallon of 41% Gly for the same price. That stuff only covers 600sf per bottle, and needs 5 days before planting.

makes sense. I also found some more gylphosate while cleaning up the garage, I had more than I thought. Enough to spray at least twice. Still need to finish digging out all the stupid rocks out there and then rake up the mulched areas before I can plant either seed or sod. Might get a small bottle of the Natria stuff to try out on smaller things, like cracks in the sidewalks, etc where the result isn't as important.

@ktgrok What all are you trying to kill off? Any bermuda in the existing mixture?
When are you trying to plant?

You're likely going to need two or three applications of glyphosate, mixed two to three weeks apart, to ensure a good complete kill of whatever is there now.

Some grassy weeds, both crab grass and I think Johnson grass, and some smaller fairly easy to kill broadleaf weeds. Also yes, some common bermuda. It's mostly bare dirt, where I had put down mulch previously, but now want to put grass. As for when, well, whenever I get it ready, lol. I'm probably going to sod with Celebration bermuda, budget permitting.
