for fall, basically, we go on 10-14 day schedule instead of weekly. 10-14 days depends on the weather. the grassusually isnt growing that fast during this time, so we dont feel the need to mow every 7 days.
spring is just a matter of doing cleanups till they are all done. if grass is growing by that time, we start mowing. if not, we do some landscaping jobs, or whatever else may need done.
