The first thing you need to consider is when to fertilize your lawn. There are many factors to take into consideration before you fertilize. First, you will need to learn about the two types of grasses, Warm-Season grasses, and Cool-Season grasses. Each of them have their own different growing season, so they’re fertilizing schedule would not be the same. For both types of grasses, it is better to fertilize when your lawn is in the growth stage.
For Cool-Season grasses, the first time you should fertilize is after the winter dormancy. The second is during the early fall when the weather has turned moderate usually after August.
