How Often Should I Mow My Lawn? (And Why It Matters)
How Often Should I Mow My Lawn?
(And Why It Matters)
Introduction
Many homeowners wonder, “How often should I mow my lawn?” The answer isn’t one-size-fits-all. Mowing frequency affects grass health, weed prevention, and the long-term appearance of your lawn. Cut too often, and you weaken the grass. Cut too little, and your lawn becomes overgrown, patchy, and more prone to pests and disease.
The key is to mow often enough to keep your lawn healthy while avoiding common mowing mistakes. Here’s how to find the best mowing schedule based on grass type, season, and growth conditions.
The Golden Rule of Mowing: The 1/3 Rule
One of the most important lawn care rules is never to cut more than 1/3 of the grass blade in a single mow. Cutting too much at once can shock the grass, weaken the roots, and leave it vulnerable to weeds and drought stress.
For example, if your lawn is 6 inches tall, you should only cut it down to 4 inches in one mowing session. If you need it shorter, wait a few days before mowing again to gradually lower the height.
Ideal Mowing Frequency by Season
Grass growth varies depending on the time of year. Here’s a seasonal mowing guide to keep your lawn looking its best year-round:
✔ Spring: Mow once per week as the grass begins actively growing. In peak growth periods (late spring), you may need to mow twice per week to keep up.
✔ Summer: Mow once per week, but adjust based on heat and drought conditions. Cutting too short in hot weather can cause stress. Taller grass shades the soil and helps retain moisture.
✔ Fall: Mow once per week until the grass growth slows before winter. The last mow of the season should be slightly shorter to prevent mold and disease.
✔ Winter: No mowing needed once the grass goes dormant. Avoid cutting frozen grass, as it can cause damage.
Grass Type Matters
In our area, the Chicago suburbs, we primarily have cool-season grasses like Kentucky bluegrass, fescue, and ryegrass. These grasses grow rapidly in spring and fall, requiring more frequent mowing during those seasons. In summer, they may slow down due to heat stress, so mowing frequency may decrease slightly.In contrast, warm-season grasses like Bermuda, Zoysia, and St. Augustine are common in places like Florida and the southern U.S. These grasses thrive in summer heat and require more mowing during warmer months, while they grow slower in spring and fall.
Knowing your grass type helps you time your mowing schedule correctly and avoid unnecessary stress on your lawn. This is something we could dive deeper into in a future post, as understanding grass types can help homeowners make better decisions for their lawn car
What Happens If You Mow Too Often or Not Enough?
❌ Mowing too often – Cutting too frequently, especially too short, weakens the lawn, making it more vulnerable to drought, disease, and pests.
❌ Not mowing enough – Overgrown grass can choke itself out, leading to uneven growth, more weeds, and increased risk of lawn diseases.
The key is balance—mow often enough to keep your lawn tidy and healthy but not so much that it stresses the grass.
Mowing Best Practices for a Healthier Lawn
Keep your mower blades sharp for a clean cut that promotes healthy regrowth.
Mow when the grass is dry to avoid clumps and uneven cuts.
Change your mowing pattern each time to prevent soil compaction and ruts.
Leave grass clippings on the lawn (mulching) for natural fertilization.
Adjust mowing height based on weather—taller grass retains moisture better in hot months.
Conclusion: Stick to the Right Mowing Schedule
Mowing is one of the easiest ways to keep your lawn looking great, but timing matters. By following the 1/3 rule, adjusting for seasons, and knowing your grass type, you can maintain a thick, healthy, and weed-free lawn all year long.
