Round Up vs Vinegar

Checked online and youtube and the vinegar looked like what I'd
rather have. I wouldn't pay the price for Round Up anyway
and don't like it. Tried my vinegar out, killed some stuff but
not the grass.

Didn't know the volume needed so I tried about a pint in a spray
bottle and covered about 120 feet. Checked my vinegar when
it didn't do much and it's so weak I could hardly smell it.
Must be several years old. I'll try later with new vinegar.

I am aware that vinegar is temporary, the grass will grow right
back in two or three weeks. I like that better than leaving a
highway of death behind. Just have to repeat it to clean again.

How much Round Up do you use?

I use Round Up sparingly. I usually just knock the weeds down with my edger. I edge every two weeks and there's only a few extra spots I trim that are outside my normal duties. The back yard has more weed problems and I won't use any harmful stuff around the dogs. I've heard about using vinegar but haven't messed with it.
