If your lawn struggles to grow and never seems to thrive no matter what type of feed, fertilizer, or watering schedule you use, it may not be that you're failing to take care of the grass properly. It may simply be that you're trying to grow the wrong grass on your property in the first place! Just like any other type of vegetation, there are different types of grass and each will grow and thrive in certain climates, and some are tough and hearty and better for difficult growing conditions.
