When Should You Cut Your Grass for the First Time? A Guide to Timing and Tips

Proper lawn care and maintenance are essential for maintaining a healthy and attractive yard. One common question that arises is when to cut the grass for the first time in the spring. Let’s explore the ideal timing for that first mowing session.

Factors to Consider

Before determining the best time to cut your grass for the first time, there are a few factors to consider:

  1. Growth of the Grass: The timing of the first mowing depends on how quickly the grass begins to grow in the spring. This can vary depending on your location and the specific type of grass in your lawn.
  2. Soil Moisture and Temperature: Grass tends to grow more actively when the soil moisture and temperature conditions are favorable. Warmer temperatures and adequate moisture promote healthy grass growth.
  3. Height of the Grass: It’s important to wait until the grass has reached a suitable height before mowing for the first time. Cutting the grass too short can stress the plants and inhibit healthy growth.
  4. Removal of Winter Debris: Before mowing, make sure to remove any leaves, twigs, or other debris that may have accumulated on the lawn during the winter months.

Ideal Timing for the First Mowing

In most cases, it is recommended to wait until the grass reaches a height of approximately 3 to 4 inches (7.6 to 10.2 centimeters) before mowing for the first time in the spring. This allows the grass to establish strong root systems and promotes healthier growth throughout the season.

The timing will vary depending on your specific location and climate. As a general guideline, it’s best to wait until the soil has thawed and the grass is actively growing. This is typically when daytime temperatures consistently reach around 50 to 65 degrees Fahrenheit (10 to 18 degrees Celsius).

For warm-season grasses, such as Bermuda grass or St. Augustine grass, the first mowing may occur earlier in the spring, as these grasses tend to become active earlier in the season. Cool-season grasses, such as Kentucky bluegrass or fescue, may require a bit more patience as they tend to grow more slowly in the early spring.

Tips for the First Mowing

When it’s time for the first mowing, here are some tips to ensure a successful session:

  1. Mower Preparation: Before starting, make sure your lawn mower is in good working condition. Sharpen the blades if necessary and check the oil and fuel levels.
  2. Mowing Height: Set the mower deck to a height that removes only about one-third of the grass blade’s length. This practice, known as “one-third rule,” helps prevent stress and promotes healthier growth.
  3. Mowing Technique: mow in a different direction each time you mow to prevent the grass from developing a “grain” and to ensure an even cut.
  4. Grass Clippings: Consider leaving grass clippings on the lawn after mowing. They can act as a natural fertilizer, returning valuable nutrients back into the soil.


Determining the right time for the first mowing of the season is crucial for maintaining a healthy lawn. By considering factors such as grass growth, soil moisture, temperature, and grass height, you can determine the ideal timing for your specific lawn. Remember to follow proper mowing techniques and adjust your mowing height to promote healthy growth. With the right approach, you can start the mowing season off on the right foot and enjoy a well-maintained lawn throughout the year.
