The best time to plant cool-season grasses is during the early fall. Warm-season grasses, on the other hand, thrive when planted in the late spring.
Summer may be the worst time to plant grass seeds. These seeds require a moist and warm environment to grow. Summer planting requires constant watering and weeding to support seed growth.
It may take up to three weeks for seeds to germinate. During the germination process, the seeds may require watering every day until seedlings appear. Seedlings may require fertilization for four to six weeks after they appear. When the grass reaches at least 3 inches high, it's ready to be mowed.
