The right type of grass–one that suits your needs and likes the local weather–will always give better results. Grasses vary in the type of climate they prefer, the amount of water and nutrients they need, their resistance to pests, their tolerance for shade, and the degree of wear they can withstand.
If you are putting in a new lawn, it will be worth your while to do some research to identify the best grass type for your needs.
If you’re working with an established lawn that fails to thrive despite proper care, you might consider replanting with a different type of grass.
Why struggle to grow grass that’s susceptible to fungal disease if you live in a humid climate? Or a water-loving species if you live in an area with water shortages? Grass that is well-adapted to your area will grow better and resist local pests and diseases better.
New grass varieties and mixtures come out on the market every year.
