How to keep grass and weeds from growing in my gravel driveway?

Make a solution with Vinegar and water add a dab of soap and a dab of salt

We have a gravel driveway and spray it with roundup twice a year. Works for us. (my hubby has a large tractor with sprayer , but we have a huge driveway). If you have a lawn tractor, you can purchase a sprayer that fits on the back of it, it makes spraying much easier.

I use a a 50/50 mix of salt and water in a garden sprayer. Saturate the gravel. Has been four years and no weeds yet.

Go with the vinegar doesn’t have the carcinogens.

I use blue down dish detergent half cup half galon w vinegar one cup salt or Epson s just on the weedsbecarefull with u plants I'm going to try corn meal too never did before
