Thanks, yes, I’ve actually used the same concoction on our gravel driveway, not getting too close to the edges as it would kill the lawn / bushes nearby. It’s a lot cheaper than the commercial “long effect” treatments!
But, here I’m basically doing a “pre-planting” treatment: After the weeds are dead / dying, then put in the garden plants. I definitely do NOT want a permanent effect.
I’m not too worried about the Roundup whacking ME as long as I handle it properly. In the course of maintaining our cars (wife’s, daughter, and my car), lots of other “around our place” chores and maintenance, and stuff I work on to make a little money (hopefully), I have to handle far worse...
Sounds good you are aware.
