PetiGreen should be applied as soon as possible regardless of the time of year, provided the ground is not frozen, so it can start building the microbes in the soil which is ultimately what protects your lawn against pet urine spots.  In areas where daytime temperatures are 45° F to 50° F or warmer during the winter it is best to use PetiGreen throughout the year since damage to roots can occur even when the grass is dormant.

In colder climates the microbial population will expand until the cold weather hits and then it will go dormant.  In the spring that expanded population will come out of dormancy and pick up right where it left off.  Then just continue with the program to improve the soil and expand the microbial population even more until your lawn is completely protected from new dog urine spots.
