May |
Cultivation (aerifying, spiking, slicing) - lawn should be actively growing. Preemergence annual weed (i.e. crabgrass) control (or late April) if needed Fertilization (1 pound of nitrogen/1,000 square feet) Postemergence broadleaf weed (i.e.dandelions) control to actively growing weeds Overseeding, establishment (early in month; late summer is better) |
June |

September |
Overseeding & establishment (optimum time) - first week Fertilization (key time) - first 2 weeks Cultivation (aerifying, spiking, slicing) - lawn should be actively growing Postemergence broadleaf weed control to actively growing weeds (optimum time) |
October |
Postemergence broadleaf weed control (early in month) if weeds actively growing Cultivation (aerifying, spiking, slicing) - lawn should be actively growing |

* Not all of these practices are suggested for one lawn in one season; this schedule is intended to be a guide when planning lawn care. Practices should be based on needs and problems of a specific lawn.
* Calendar can be adapted to other parts of Illinois
* Some practices cannot be done in conjunction with another; such as reseeding and applying most herbicides, or fertilizing new seedings at rates for established lawns.
