Mowing frequency naturally decreases as temperatures drop in late autumn because grass growth slows significantly. During this period, it’s essential to adjust your lawn care routine to ensure a healthy lawn come spring. Here’s a comprehensive guide to understanding how mowing frequency changes with the seasons and practical tips for your lawn care routine.
Why Does Mowing Frequency Change in Late Autumn?
As temperatures drop in late autumn, grass growth slows down due to reduced sunlight and cooler temperatures. This natural slowdown means that you won’t need to mow as often as you did during the warmer months. Typically, mowing once every two to three weeks is sufficient during this time, but this can vary depending on your specific grass type and local climate conditions.
How Often Should You Mow Your Lawn in Autumn?
Factors Affecting Mowing Frequency
- Grass Type: Cool-season grasses, like fescue and bluegrass, may continue growing longer into the autumn compared to warm-season grasses like Bermuda and zoysia.
- Local Climate: Cooler regions will see a more rapid slowdown in grass growth, while milder climates may allow for continued growth.
- Soil Conditions: Well-drained soils may support longer grass growth, whereas compacted or waterlogged soils can hinder it.
General Mowing Guidelines for Late Autumn
- Monitor Growth: Check your lawn regularly. If the grass is still growing, continue to mow as needed.
- Adjust Mower Height: Gradually raise the mowing height to leave grass slightly longer. This provides insulation against cold temperatures.
- Mow Less Frequently: As growth slows, reduce mowing frequency to every two to three weeks.
- Avoid Cutting Wet Grass: Autumn rains can make grass wet, which can lead to uneven cuts and potential damage to your mower.
What Are the Benefits of Adjusting Mowing Frequency?
Adjusting your mowing frequency in late autumn has several benefits:
- Promotes Healthy Grass: Longer grass shades the soil, reducing weed growth and retaining moisture.
- Prepares for Winter: Properly maintained grass is more resilient to winter stresses.
- Reduces Disease Risk: Frequent mowing when unnecessary can stress grass and increase disease susceptibility.
Practical Tips for Late Autumn Lawn Care
- Fertilization: Apply a fall fertilizer to strengthen roots and prepare the lawn for winter.
- Leaf Management: Regularly remove fallen leaves to prevent smothering the grass.
- Irrigation: Reduce watering as natural rainfall increases and temperatures drop.
- Aeration: Consider aerating your lawn to improve soil health and root growth.

How Does Temperature Affect Grass Growth?
Grass growth is temperature-dependent. Cool-season grasses thrive in temperatures between 60-75°F, while warm-season grasses prefer 80-95°F. As temperatures drop in autumn, growth naturally slows, reducing the need for frequent mowing.
Can Mowing Too Late in the Season Harm the Lawn?
Yes, mowing too late in the season can harm your lawn. Cutting grass too short before winter can expose roots to cold temperatures, increasing the risk of winter damage. Ensure your final mow leaves grass slightly longer.
Should You Mow Before a Frost?
Avoid mowing right before a frost. Mowing can stress grass, and a subsequent frost can cause further damage. Plan your mowing schedule to allow grass time to recover before cold temperatures set in.
Is It Necessary to Rake Leaves Off the Lawn?
Yes, it’s necessary to rake leaves off the lawn. Leaves can block sunlight and trap moisture, leading to disease and decay. Regularly removing leaves helps maintain grass health.
What Is the Ideal Mower Height for Late Autumn?
The ideal mower height for late autumn is about 2.5 to 3 inches for most grass types. This height helps protect the grass crown from cold and supports root development.
Summary
As temperatures drop in late autumn, mowing frequency should decrease to match the slowed growth of your lawn. By adjusting your mowing habits and incorporating other seasonal lawn care practices, you can maintain a healthy lawn that is well-prepared for winter.
