Bermuda Grass: Short or Long?
I have a full Bermuda lawn. I've done some research about trying to get rid of and prevent weeds and read that I should keep my grass long to block as much sunlight reaching down to weed seedlings as possible (among other benefits of long grass). However, I also read that Bermuda prefers to be short.
Which should I do? Should I cut it short (2" or less) or let it grow to 3"? Is there any harm in letting Bermuda grow long?
