Mr. Bowden [on TV] stated that when cutting the lawn the mower deck should be approximately 4″ above the ground. At least that is how I interpreted it. Did I mis-understand? It was in reference to the dry period we had without rain. Thanks,
Yes, in my garden segment (which you can find on my blog here: http://ourgarden.freedomblogging.com/ I suggested letting the lawn grow to about 6″ and then mowing it back to 4″ during the hot part of summer. These taller blades will shade the soil below preventing it from overheating. If the soil temperature goes to above 85° to 90° for three or four days the roots start to die. In mid August or so when rain gets more regular and the high heat of summerwanes we can go back to letting the grass grow to about 4″ then mow it back to 2 1/2″ to 3″ to encourage side growth and thickening of the lawn through fall.
