I will respond on behalf of many on this board....how many times you would cut the same property in a week could depend on the following:
height of blade
part of the country
Which such a general question, it can be difficult to answer it accurately because there are so many factors involved. The spring through the hottest part of the summer I usually cut every 5 days. Sometimes a bit sooner and sometimes later. Weather plays a huge factor in the mowing season too.
I ask because I have problems with customers that only want mowing once a week, but in spring and early summer when the stuff is growing like "grass" It should definately be cut at about 5 days. It is hard to explain to these pita's that it needs cut more often.
