How Mowing Grass Affects Turfgrass Growth


The Relationship between Grass Mowing and Grass Growth in Your Lawn

In order to maintain a quality lawn, the turfgrass must be mowed correctly. This is the first and most important lawn maintenance practice. Refer to the Scotts LawnService grass mowing tips and best practices guide for more information.


Grass mowing – while necessary for proper lawn maintenance – is actually considered a stress to the turfgrass plant. It removes leaves that generate energy for grass growth and development. To survive, the plant uses reserve carbohydrates to re-grow leaves.

In order to minimize plant stress from mowing, mow high and frequently enough so that no more than 1/3 of the leaf blade is removed in a single mowing. Mowing grass at the high-end of the recommended range of mowing heights for different turfgrasses will produce the best looking lawns.

Avoid Scalping When Mowing Grass


Since new leaf growth occurs at the base of the plant, crowns can be damaged when mower blades are set too low. If the crown is damaged new leaf growth is unlikely. Even if the crown is not damaged, the lawn is weakened because it has to use stored energy to re-grow. A weak and thin turf is less competitive and allows weeds to grow and become a problem.
