Fall is the ideal time to fertilize turf. Among the benefits are better fall and winter color and a quicker green-up earlier in spring continuing into summer. Also, there will not be excessive blade growth as in lawns that are fertilized in spring. Other benefits that result from fall fertilization are winter survival and optimum root growth.
In basic terms it works like this: nitrogen is taken up by the roots, even though blade growth has ceased. Roots remain active during cooler temperatures. Nitrogen increases chlorophyll content, thereby enhancing color. More chlorophyll equals more photosynthesis equals increased sugars. Because turf blades are not growing during this time that sugar is being stored, winter survival and spring recovery is enhanced. As a result turf goes into spring and summer with deeper, healthier roots, and spring green-up is earlier because of the nitrogen stored in the roots.
