It depends on so many factors, it's hard to answer that. The area that you work in, the season, how much growth you've accumulated and how quickly. It's really up to you though, if you want to take on a lot of calls and work long hours you can, if you don't then don't. When I started I was working 10-12 hours a day, now I'm in my 4th year I have it down to 8 - and that's all I want to work for now with my busy life. In the winter sometimes I'll work 5-6 hours some days and in the summer I'll work 12. It's really up to you.
The hours gone varied depending on where the district office sent me for one time calls
10 to 12 hours per day but the days fly by
