Hi Whitney...thanks for the advice. The solution I use works for a little while but then need to reapply so anything that will help for longer I'm willing to try!

Hi Christine! If you have any Asian food markets near you, check to see if they have 20% acetic acid vinegar. You need to dilute it and be very careful using it, and it's NOT for consumption of any kind, but it does a great job on really stubborn weeds. Adding a drop or two of liquid dish detergent to the mixture will make it stick to the leaves of whatever you're trying to kill. Spray on a hot day with no breeze and watch those weeds wither and die. I also read the other day that vodka will kill broadleaf weeds (recipe for spray: 1 oz vodka, 2 c water, a few drops of dish detergent).
