We start mowing first week of april most years , Cleanups are all thru the winter as long as the ground isnt frozen solid ! When the ground is frozen its cold beer and working on stuff around the hosue !!
For us the Fescue mowing normally starts in March, while the Bermuda isn't ready until the middle of April. However it has been unseasonably warm and the Bermuda runners are greening up so will start early this year. Narmally runs until October for Bermuda and longer for Fescue.
