Is It Better To Keep Grass Long Or Short

Maintaining long grass has distinct advantages. It blocks out weeds, provides insulation to protect roots during freeze-thrift frost events, reduces evaporation from soil, and prevents soil compaction. 

At the same time, gardening experts warn that long grass can also lead to problems such as an increased risk of mower-related injuries. Excessive heat and humidity is another issue that comes with longer plants; soils deplete quickly in uncontrolled conditions.

Shorter grass has benefits too. A shorter height lets more sunshine reach plants’ bases, encouraging photosynthesis and growth. Plus it’s more visually appealing than tall plants and easier to maintain–especially with automated mowers and edgers. 

But it’s important not to trim too aggressively; doing so will leave plants vulnerable to insect attack, drought stress and sunburn. Best practice is to aim for a middle ground: keep grass between two inches and four inches tall when taking into account local growing conditions.  

To maintain grass at the optimal length no matter what climate you live in – warm or cold – look for the tools that make it easy such as mulching mowers for those who don’t want to bag clippings or robotic lawnmowers for something more hands off. Start by gaining knowledge about your climates average mowing needs—and make sure your lawn looks lush year-round!
