Spring marks the return of many things. Trees and flowers begin to bloom again in spring, while warmer temperatures are welcomed back with open arms. Grass also begins to grow again in the spring. That means it’s not too long before homeowners have to dust off their lawn mowers and get to work. Those who don’t necessarily enjoy mowing the lawn may be tempted to cut their grass very low, as doing so can mean longer intervals between mowing sessions. However, mowing grass too low can have a very adverse effect on a lawn.
Cutting too low can injure the grass. Cutting grass too low can injure the grass, creating what’s essentially a domino effect of problems to come. Injured grass will focus on its recovery efforts, thereby making it vulnerable to other issues.
Cutting too low promotes weed growth. Injured grass is vulnerable to invaders, including weeds and insects. Weeds and insects can attack grass as it recovers from injury, and before homeowners know it, their lawns are overcome with a host of problems.
Cutting too low allows crabgrass to thrive. Crabgrass needs ample sunlight to grow. By cutting grass too low, homeowners may unknowingly be promoting crabgrass growth. Crabgrass is unsightly and can rob surrounding grass of the moisture it needs to grow. So lawns cut too low may not only lose their lush appeal thanks to the unattractive appearance of crabgrass, but also because areas surrounding the crabgrass patches might turn brown due to lack of water.
Cutting too low can stress the grass. Cutting too low also makes lawns vulnerable to summer heat. Without blades tall enough to block some of the summer sun, grass can quickly succumb to summer heat, leading to dried out, discolored lawns.
