Maintain a two to four inch layer of mulch on the soil surface to reduce weeds, infiltrate rain water, and reduce compaction.
In the fall, unless it is very hot outside, you can reduce your total watering time by 1/2.
Do not reduce run times, reduce the number of watering days.
Remove irrigation water and fertilizer from areas where you don't want weeds to grow.
