It is time to fertilize! The most important fertilization of the year is applied in the fall. Fertilizer applied to lawns in the fall helps root systems recover from summer stress and develop food reserves for an earlier and better spring. Your lawn and trees consume a lot more food in the fall than through the rest of the year. Your entire landscape “shifts gears” in the fall to begin storing food in preparation for the explosive new growth of spring. Fall fertilization makes nutrients available that may not be present in some poor soils. The healthier the roots become the better growth you can expect in the spring.
