Lawn care might seem straightforward, but knowing when and how often to mow is crucial to keep your grass healthy and lush. Seasonal changes, weather patterns, and grass types all influence your mowing schedule. This guide will walk you through the best mowing frequencies for each month, so you can enjoy a vibrant lawn all year round.
1. January – February: Winter Dormancy
Mowing Frequency: Minimal or none
Details: During winter, most grasses are dormant and don’t require frequent mowing. If you live in a warmer climate with a cool-season grass type (like fescue), you may mow once or twice, but for most people, winter is a time to let your mower rest. Ensure your lawn is clear of debris, which can encourage fungal growth if left on the grass for long.
2. March – Early Spring Growth
Mowing Frequency: Once every 2 weeks
Details: As temperatures rise, the grass will start growing slowly. Begin mowing every 2-3 weeks, depending on your grass type and growth rate. Cool-season grasses, like ryegrass or bluegrass, may need slightly more attention as they start to “wake up” in spring. Adjust your mower height to trim the grass lightly, removing only about a third of its height.
3. April – Spring Ramping Up
Mowing Frequency: Once every 1-2 weeks
Details: April brings warmer days and the beginning of peak growth for many grasses. Increase your mowing frequency to once every 1-2 weeks. Keep an eye on how fast your grass is growing; during a wet or mild spring, you might need to mow even more frequently. Maintaining consistent mowing prevents overgrowth and encourages denser grass, which crowds out weeds.
4. May – Early Summer Growth
Mowing Frequency: Once a week
Details: In May, both cool-season and warm-season grasses enter a period of rapid growth. Set your mowing schedule to once a week for most lawns, and keep your mower blades sharp to make clean cuts. Cutting grass weekly helps keep it at an ideal height, around 2.5 to 3 inches, which protects it from pests and keeps it healthy as temperatures rise.
5. June – Peak Growing Season
Mowing Frequency: Once a week or more
Details: June is one of the most intense growth months for many grass types. Mowing once a week, or even more often for fast-growing varieties like Bermuda or Zoysia, will help maintain a uniform, well-manicured lawn. For cooler-climate grasses, aim to mow early in the morning or evening when temperatures are lower to minimize heat stress.
6. July – Mid-Summer Heat
Mowing Frequency: Every 1-2 weeks
Details: As summer heats up, grass growth may start to slow. In July, mowing once every 1-2 weeks is usually sufficient. Raise the mower blade slightly to leave your grass a bit longer; taller grass helps shade the soil, retaining moisture and reducing stress from summer heat. Water deeply and early in the day for optimal moisture.
7. August – Late Summer Slowdown
Mowing Frequency: Every 1-2 weeks
Details: In August, lawns typically require mowing every 1-2 weeks, depending on the weather. Consistent high temperatures can stress the grass, so avoid cutting it too short. Keep a close eye on moisture levels, as dry grass is more prone to damage. If you experience drought conditions, cut back to every 2 weeks or as needed.
8. September – Cooler Fall Weather
Mowing Frequency: Once a week
Details: September brings cooler temperatures and often a bit more rain, which reinvigorates growth in many grass types. Return to a weekly mowing schedule to manage this renewed growth. If you’ve been mowing with the blades set high for summer, you can gradually lower them a bit to prepare the lawn for winter dormancy.
9. October – Preparing for Dormancy
Mowing Frequency: Every 2 weeks
Details: As fall deepens, most lawns begin to slow down. Mow every 2-3 weeks to keep your lawn neat as growth decreases. Lower your mower deck one final time, taking off about an inch to prevent snow mold and other winter diseases if you’re in a cold climate.
10. November – Winter Preparation
Mowing Frequency: Minimal once per month
Details: By November, most lawns have gone dormant. You may not need to mow at all, but if your grass is still growing slightly, mow only as needed. Give your mower one last clean-up and tune-up before storing it for winter.
11. December – Off-Season
Mowing Frequency: None to once a month
Details: December is typically a month off for your mower. Winter lawn care should focus more on maintenance, like removing fallen leaves and debris, which can harm the lawn. Enjoy the break, and start preparing for the next growing season.
Final Tips for a Healthy Lawn Year-Round
•Adapt to Your Climate: Grass growth patterns vary widely by region. Southern areas may require more frequent mowing in winter, while northern areas experience long dormancy.
•Know Your Grass Type: Different grass types (like cool-season vs. warm-season) have specific needs. Research your grass type to make sure you’re mowing at the right height and frequency.
•Mow at the Right Height: Never remove more than one-third of the grass blade in one mow, as this can stress the plant. Adjust mower height based on the season and weather.
•Keep Blades Sharp: Dull mower blades tear the grass, leading to brown tips and making your lawn more susceptible to disease.
By following these seasonal guidelines, you’ll maintain a lush, healthy lawn all year long.
