Overall, growing grass in New Jersey can be a challenge, but with the right grass species and proper maintenance, it is possible to have a lush, healthy lawn.”
Introduction
New Jersey has a humid subtropical climate, which means it has hot, humid summers and cool to cold winters. This climate affects the types of grass that are best grown there because it requires a grass species that can tolerate both extremes of temperature.
The best time to lay grass in New Jersey is during the late summer to early fall when the soil is still warm but the temperatures have started to cool down. This allows the grass to take root and establish itself before the winter months.
New Jersey is located in the grass zone known as the transition zone. This zone is characterized by its unpredictable climate, with hot summers and cold winters.
The transition zone is known for its challenging growing conditions, as it is not quite warm enough for warm-season grasses and not quite cool enough for cool-season grasses. Therefore, it is important to choose a grass species that can tolerate the fluctuating temperatures of this zone.
Which grasses grow best in New Jersey?

What is the best time to lay sod in New Jersey?
