So We typically pay the higher cost charged for 2 of these 24oz containers of product. The 1st, and part of the second container We use for the 1st spray around the typical property areas in early-late Spring. The remainder of the 2nd container usually just helps Us manage Our weeds, and such throughout the remainder of the Summer and in...

It was an absolute mess and when I was done cleaning it all up, I called Lowe’s customer service to get a refund on the gallon that emptied i...
