Roundup on bricks dangerous for other parts of yard?
I bought some roundup last year and never used it, because I don't like chemical stuff and I'm kind of afraid, however, I have 3 brick walks on my property that are becoming covered in errant grass and weeds and I really want to clean them up.
I am concerned about using the RU because I plan to do other planting in my yard (jasmine for ground cover, flower beds, a vegetable garden) but if I use the RU only on the bricks will it "spread" to the soil nearby and hurt other things?
Also, I have cats. Dogs too but they are inside mostly. Do I abandon all RU plans or is it safe if I keep the animals off the area until it's dry/absorbed/whatever?
