This message is specifically for people living in Southern Ontario. What height do you mow your lawns at during the summer. In the spring, 2 1/4 or 2 1/2 looks great. However in the summer, 2 1/4 is too short so I tend to stick to 2 1/2. I feel, however, that this will cause the grass to burn out even with mulching. I have tried cutting at 2 3/4" and 3" but felt the lawn looked a little shaggy after I was done. What does everyone else think?
