Many homeowners stop watering in early fall, however, historic data shows that about 1/2 an inch per week of irrigation can still be needed in the fall to maintain healthy turf until the turf goes dormant for the winter. Fall watering is also essential for late season fertilization to work most efficiently.
Fall fertilization is important to strengthen root systems for the coming spring. The fertilizer must be watered in properly to realize the full benefits. The fall is also the best time of the year to control some perennial weeds such as dandelions, clover, and thistle. When the weed killer is applied to healthy growing weeds it will be most effective.
Core aeration is also a very important part of the yearly lawn maintenance routine. The aeration will relieve soil compaction and allow water and fertilizer to penetrate the ground better to benefit the roots.
