Quick Answer
The most common mowing mistake homeowners make is cutting their grass too short, often known as 'scalping.' This weakens the grass, stresses the root system, and creates an open invitation for weeds to take over. To fix it, raise your mower deck to its highest setting (typically 3-4 inches) and only remove one-third of the grass blade's height per mow, promoting a deeper, stronger root system and naturally suppressing weeds.
The Problem
Many homeowners believe a shorter lawn looks tidier or means less frequent mowing. While this might seem appealing, it's a critical error that severely impacts the health and appearance of your grass. Cutting grass too short, often referred to as
Frequently asked questions
How often should I mow my lawn?+
The frequency depends on your grass type, growth rate, and desired height. Generally, aim to mow often enough so that you only remove about one-third of the grass blade's height with each cut. This might mean once a week during peak growing season or less frequently during cooler or drier periods.
What happens if I cut my grass too short?+
Cutting your grass too short (scalping) stresses the plant, reduces its ability to perform photosynthesis, weakens its root system, and leaves the soil exposed, making it much easier for weeds to germinate and thrive. It also makes your lawn more susceptible to disease and insect damage.
Should I bag or mulch my grass clippings?+
Whenever possible, mulching your grass clippings is beneficial. Clippings return valuable nutrients and organic matter to the soil, acting as a natural fertilizer. Bagging is only necessary if the clippings are excessively long and thick, which could smother the existing grass, or if you're battling a severe weed problem with seed heads.
