The Best Time to Mow Your Lawn

Lawn mowing

We all want our lawns to experience uniform growth without patches of overgrown or sparse areas. Luckily, one way to achieve that is by mowing at the right time.

That said, what is the best time to mow your lawn for the best results? If you’re in this dilemma, here are the key considerations to make when determining the best time to mow your lawn for the best results: 

Grass Growth Rate

Different grass species exhibit different growth rates. Consequently, your lawn’s growth rate will influence your mowing schedule as follows:

  • Cool-Season Grasses: Popular varieties include; ryegrass, fescue, and Kentucky bluegrass. These grass species experience fast growth rates in cooler months, especially spring and fall. As such, you may need to increase the mowing frequency in peak growing seasons.
  • Warm-Season Grasses: Top examples include; St. Augustine, Zoysia, and Bermuda. These grass species experience accelerated growth rates in warm summer months. Consequently, warm-season grasses need regular mowing in warm summers.

Weather Conditions

Mowing in dry weather helps mitigate clumping and provides a cleaner cut. You should expect dry weather in specific months or seasons, depending on your jurisdiction.  Generally, dry weather coincides with:

  • Summer Months: Scheduling your mowing sessions during dry spells is vital in achieving optimal lawn care results. In many regions, summer months tend to be dry with minimal precipitation. 
  • Late Afternoons & Early Mornings: Humidity levels are lowest in the late afternoons and early mornings. Mowing during these openings results in quick drying times, minimal clumping, and even cuts. 

Time of Day

Avoid mowing during hot spells since this will stress you and the grass. Instead, opt for morning or late afternoon mowing sessions. Here’s why these times are optimal for mowing:

  • Early Morning Mowing: It will help to opt for early morning mowing sessions between 8 and 10 AM to take advantage of reduced temperature and humidity, which reduces stress on the grass. Moreover, morning mowing results in a clean cut, thanks to the lubrication of grass blades by morning dew. 
  • Late Afternoon Mowing: You can mitigate stress damage by mowing your lawn late in the afternoon to allow the grass to recover overnight. The best time for late afternoon mowing is anytime before sunset after 4 PM. 

Mowing Frequency

Regular mowing encourages healthy grass growth and eases lawn management. However, mowing frequency depends on a variety of factors including; environmental conditions, grass species, growth rate, and more. Here are guidelines that will help you determine your mowing frequency:

  • Cool-Season Grasses: These grass types require frequent mowing sessions during active growth periods in spring and fall. As such, aim to mow cool-season grasses every 7 to 10 days during peak growing seasons.
  • Warm-Season Grasses: These grass varieties may exhibit stagnated growth in cool weather or periods of slow growth. However, regular mowing in warm weather mitigates turf overgrowth.

Grass Height

Adjust the mowing height to suit your grass species. Also, remember never to mow more than one-third of a grass blade’s length.  Here’s how you can determine the ideal mowing height for common grass types:

  • Cool-Season Grasses: Avoid cutting cool-season grasses like fescue and Kentucky bluegrass too short. Taller grass blades are essential in shading the soil and enhancing moisture retention. Therefore, set your mower height to 2.5 to 3.5 inches for cool-season grasses.
  • Warm-Season Grasses: For improved weed suppression and lush dense growth, ensure warm-season grasses like Bermuda and Zoysia enjoy short mowing heights. As such, set your mower height to 1.5 to 2.5 inches for warm-season grasses. 

When to Fertilize Your Lawn

Fertilizing a lawn

Gardeners, landscapers, and homeowners who make informed fertilizer timing decisions excel at growing and maintaining healthy lawns. Moreover, proper fertilization timing promotes robust root systems and stress resistance, plus reduces weed infestation. 

Here are essential factors to consider before lawn fertilization:

Grass Type

Choose a fertilizer that meets your grass species’ nutrient requirements. Different grass types have varying requirements when it comes to nutrients like Nitrogen, Phosphorus, and Potassium. 

Conduct soil tests to determine your lawn’s nutrient deficiencies as this will guide your fertilizer selection process. Cool-season grasses like Kentucky bluegrass thrive in soil with Nitrogen, Phosphorus, and Potassium in the ratio of 3-1-2. In contrast, warm-season grasses like Bermuda and Zoysia may require higher Nitrogen content to support their growth during active growth seasons. 


Time fertilizer application to coincide with active growth periods like fall and spring. Temperatures begin to rise with spring’s onset, which results in grass emerging from their dormancy. Consequently, fertilizer application that coincides with spring’s active growth periods facilitates vigorous growth. 

Likewise, fertilizer application in the fall strengthens the grass roots, preparing your lawn for winter dormancy, and a healthy lawn in the following spring. By supplying nutrients when the grass is actively growing, you enhance robust root and shoot development while promoting overall plant health. 

Soil Temperature

The ideal soil temperature for lawn fertilization is 55°F and 85°F (12°C to 29°C). These temperatures are conducive to root nutrient uptake. 

Rainfall Forecast

Fertilization should occur a day or two before imminent downpours to enhance nutrient activation while mitigating fertilizer runoff. 

Avoiding Stress Periods

Fertilizing during stress periods like drought and extreme heat should be avoided, as this can further stress the grass.
