**The general rule of thumb when it comes to mowing grass is to cut off one-third of the blades height.

Any grass regardless of cool or warm season -- will never respond well to having more than a third removed at any time. Grass blades are the food factories if the grass plant and removing too much of the working part of the plant puts the plant into shock and much of the nutrients are lost until the leaf grows back and seals the "wound" made by the cutting.

Bentgrass

This unique grass needs special attention paid to it. Mowing needs to be taken seriously when dealing with bentgrass.

Height

• Generally mowed between ¼ and 1 inch.
  
• This grass can be cut so low because of its low to ground, horizontal growing habit, and because of its very low meristematic tissue
  

Direction

• Bentgrass should be mowed at a different direction every time it is mowed.
  
• This is done to ensure that a "grain" is not developed. Grain is formed when the grass is mowed in the same direction every time.
  
• A grain on a golf course green is very undesirable for putting because it can make the golf ball go off line.
  
• Example for mowing directions:
  -Imagine a green is a giant clock.
  
• One day mow in the direction of 12 to 6 o'clock, then the next day mow 3 to 9. Change directions every time it is mowed, and two other directions of mowing are 10 to 4 and 8 to 2.
  A green should be mowed nearly everyday.

Fescue, Blue, and Rye grass:

These grasses are very similar in growth habit, cut of height and uniformity, for this reason they are often intertwined on home lawns, as well as the "rough" on a golf course.

Bluegrass: one to three inches
Ryegrass: 2 to three inches
Fescue: 1 to 4 inches (Depending on cultivar).
