Our lawn must be the fastest growing lawn ever! It has to be mowed every week. Investigating on the Internet about what kind of grass we had in our front and backyard I learned a couple of things I didn't know.
You have to choose the right kind of grass for your yard, some like shady places, others need direct sunlight, just like plants.
Don't cut the grass too short, is not good for the lawn.
Don't mow your lawn when its wet, otherwise you might get weeds in your whole yard.
Water the grass frequently (we actually dont need that, the frequent rains and the lack of sunlight are in charge of taking care of our lawn).
Fertilize it when is needed.
