They also have an enormous grounds-keeping budget that would make most of our annual fertilizing and watering expenses look like pocket change.

Mowing Bluegrass Shorter

You can keep your Kentucky bluegrass shorter than indicated above, but it will require extra care to maintain a presentable look through the summer. When you mow low, the root system will likely be shallow and there is a greater risk of turf grass damage when soil moisture is minimal.
