Is it better to cut grass long or short?
Stress to the grass plant can be caused by mowing too short. Grass plants that are weak will take longer to recover. Before the grass is 4.5 inches tall, mow it. Increasing the risk of root rot by mowing too short can allow weed seeds to get more sun.
The length of your mowed lawn depends on a number of factors, including the type of grass you have, the amount of water you use, and whether you are mowing at night or during the day. For example, if your lawn is 3 feet tall, it should be 3 to 4 inches long. If your grass is 2 feet high, you should cut it down to 2 to 3 inches.
The longer the lawn the more time you will have to water it and the longer it will need to dry out before it can be re-mowed. In general, a lawn that is longer than 4 feet will require more water than a shorter lawn. This is because it takes longer for the water to evaporate from the surface of the soil and to reach the roots.
A longer lawn also requires more fertilizer to maintain the same level of nutrients.

A mowing height between 2.5 to 3 inches is best for most of the season, except during summer stresses when the lawn mowing height should be raised one-half inch to mow at 3 to 3.5 inches. Raising the mowing height reduces the amount of water that is lost from the grass.
The width of a mower blade is the distance between the blade tip and the ground surface. For most lawns, the width is between 3 and 4 inches, but it can vary depending on the type of grass, soil type, and other factors.

A width between 5 and 6 inches can be used for turfgrass, as long as it is well-drained and has good drainage. Lawn mowers should not be mowed wider than 6 to 8 inches to avoid damage to the blades and to reduce the amount of water that is lost to evaporation.
