  2. Many homeowners stop watering in early fall however historic rain fall data shows that about ½ an inch per week of irrigation can still be needed in the fall to maintain healthy turf for the start of winter.  If the lawn is stressed going into winter this can cause problems in the spring.  The fall is a good time to get the grass into good shape after a hot summer.  Fall watering is also essential for late season fertilization to work most efficiently.

    Fall fertilization is very important to the health of turf areas.  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 weeks such as dandelions, clover, and thistle.  When the weed killer is applied to healthy growing weeds it will be most effective.

    The ideal height for growing turf in Colorado is about 2.5 - 3 inches.  Mowing shorter than 2 inches can result in decreased drought resistance and higher incidence of insects, diseases and weeks.  There is no reason to mow shorter in the fall.  Regular mowing also helps the turf stay healthier.

    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.
