You may think it a simple task, but lawn care maintenance – the task of maintaining a healthy, well trimmed lawn is sometimes harder than it looks and knowing when and how often to cut the grass is a skill worth learning.
Longer grass grows slower than shorter grass. As the blades grow longer, the grass gets healthier and becomes visible by its rich dark green coloring. This is due to photosynthesis. The greater the surface area of the blade, the greater the rate of photosynthesis. Longer blades of grass also hold more moisture.
The roots of longer grass take over more space below the ground and help to phase weeds out. The same affect occurs on the surface area - the longer the grass, the more nutrients are absorbed by it, thus lessening the nutrients available for weeds to survive.
As longer grass grows slower than shorter grass it figures that frequently cut grass will require more regular cutting. If you aren't worried about having a perfect lawn the whole time, leave the grass a little bit longer before you cut it again to save time and effort.
On the adverse side, grass that is left too long will encourage unwanted bugs who thrive in cool, shady places. Grass that is too long will also eventually go to seed, causing the grass to die off. Cutting grass is therefore actually better for its existence.
When you cut the grass much depends on how tidy you want your garden to look. If you don't mind it looking slightly scruffy from time to time, allow it to grow a little longer. It will become a healthier crop and will save you lots of time in the long run.
