how soon can you fertilize new grass
While lawn grass will survive without fertilization, it will not look and perform to the standards most people expect. A healthy, green, lush lawn is generally a result of a correct fertilization program. You will find a lot of different opinions among the experts, about how often and when to fertilize. In general you should fertilize at the beginning of the growing season when the type of grass you have (cool or warm season) most actively grows. For cool season grasses this is in fall and spring.
