Here is an interesting article from the National Association of Realtors that pretty well fits Denver’s grass growing seasons, and why it is important to fertilize in the fall.
I will make a personal comment though about mulching the grass in our south Denver community… if it is so good why do we power rake in the spring? Our grass clippings and leaves simply do not decompose as quickly as those in a more humid climate. They stay dry.
In Highlands Ranch I do use those leaves after being bagged in my mower along with the last couple of mowings, for mulch around my roses.
