When dog urine is introduced to the soil your lawn cannot tolerate the dramatic increase in pH in that concentrated area. EVOLVE Organic Dog Spot Prevent works for your lawn in a couple different ways!
Details: Reduces the overall pH of your soil to approximately 7 so that the impact of the higher pH of urine is much less. Also absorbs urine on impact and will then slowly introduce it to your soil further reducing its ability to increase the pH of your soil.
In order to lower and maintain the pH of your soil, Dog Spot Prevent has to be applied three times per year for best results - spring, mid summer, and fall.
