Using Primo Maxx to Reduce Mowing Frequency: Practical Tips for Homeowners


Taking care of a lawn can be labor intensive, especially when frequent grass mowing is required. However, with Primo Maxx, homeowners can maintain their lawns at the required height. Although Primo Maxx was commonly used in golf, it is now used at home. 

Primo Maxx can reduce mowing frequency by 50 percent and help grow thicker, healthier grass that is less susceptible to environmental factors. This article discusses how Primo Maxx can save you time and effort in maintaining your lawn and how to use it effectively.

What Is Primo Maxx, And How Is It Used?

Primo Maxx is a plant growth regulator used to control the vertical growth of grass, thus minimizing the frequency of mowing and edging. By encouraging lateral growth, Primo Maxx facilitates the formation of thicker and denser grass. 

Besides reducing the mowing frequency, Primo Maxx increases the stress tolerance of the grass to heat, lack of moisture, and diseases. Using Primo Maxx also encourages root development, making the lawn healthier and capable of withstanding various weather conditions.

Application Rates, Timing, and Mixing

For warm-season grasses like Bermuda, Zoysia, and St. Augustine, apply 0. 25 to 0. 50 ounces per 1,000 square feet when the grass is thriving and the temperature is above 65° F. For cool season turf grasses such as Kentucky Bluegrass, Fescue, and Ryegrass, apply 0. 10 to 0. 25 ounces per 1000 square feet in spring and when the grass is actively growing. 

Typically, one application of Primo Maxx suppresses the growth rate for about one month. When applying Primo Maxx, follow the manufacturer’s instructions. Dilute it with water and ensure it is well mixed to avoid clumping. Properly spray the Primo Maxx solution over the lawn using the backpack sprayer or the hose-end sprayer. 

Ensure the grass is completely moistened to achieve the best results. Additionally, use Primo Maxx when the weather is good, not when it is rainy or very hot, since these conditions might hinder the product’s effectiveness. Therefore, the most suitable application time is early morning or later afternoon to reduce exposure to excessive heat.

Tips for Optimal Results

Primo Maxx is most effective when applied to a healthy lawn. Therefore, ensure the lawn is well-fertilized, watered, and weeds-free before applying. Also, pay close attention to the condition of your lawn after applying the fertilizer and observe whether it shows signs of being overfertilized. 

It is also important to note that Primo Maxx only reduces the frequency of mowing. Therefore, aeration and watering are also best practices to ensure that the lawn is healthy. You may require more frequent fertilizer application in the season when there is more active growth than when growth is minimal.


Primo Maxx effectively minimizes mowing and maintains a visually pleasing lawn. However, it is important to understand how to use this growth regulator in the right way so that it integrates into your lawn care routine. Furthermore, since Primo Maxx increases the grass density, it boosts the lawn’s ability to resist infection and insects.
