So easy!
This is wonderful stuff -- I have what used to be called an English Mastiff, and we moved to a place with a small backyard where all the grass had died back to dirt. In short order, I could tell that urine odor from my dog was going to become a problem with the dry ground, until I could get a yard in, and so bought this, thinking I would also need yard spray.  This worked overnight with me tossing some granules about the yard, and I have never needed the spray at all. It has a handy shaker top, but of course I didn't discover this part until later, but for sure, it works!
