i do a 6 step program to i like granular fert and liquid for weeds because if it rains or gets windy i don't have 200 gal of product to store and no leaks to worry about is why i stick with the granular products, also i can apply different fertilizers to different lawns during the day. as 4 use it gets used heavy in spring and in the fall and 1 or 2 days the rest of the season. sometimes i just use a backpack sprayer.
