The Importance of Mowing Frequency and Direction

Maintaining a dense, healthy lawn requires more than just water and fertilizer. One of the most crucial aspects of turfgrass care is mowing. Not only does it keep your lawn looking neat, but it also significantly impacts the health and vitality of the grass. In this article, we'll explore why mowing frequency and direction are key to achieving a beautiful, resilient lawn.

Why Mowing Frequency Matters

1. Promotes Thicker Grass: Regular mowing helps promote thicker and healthier turf. By cutting frequently, you're essentially telling the turf to adapt to new restrictions. These restrictions are that the plant should stop growing above a certain height, or it will consistently get slashed! Since the primary function of the foliage is to capture sunlight, limiting the plant's vertical "space" promotes horizontal growth in pursuit of collecting just as much sunlight as before. Thus, frequent cutting of your turfgrass promotes a higher shoot density and finer texture.

2. Reduces Stress: Grass can become stressed if too much is cut off at once. Following the "one-third rule" – never removing more than one-third of the grass blade at a time – ensures that your grass remains healthy and robust. Frequent mowing keeps the height manageable and reduces stress on the plant. If we wait too long between cuts, we could violate the rule of one-third, potentially stressing the plant and resulting in thinning, weed encroachment, discoloration, disease susceptibility, etc.

3. Enhances Appearance: A well-manicured lawn looks inviting and boosts curb appeal. Regular mowing keeps the grass at a uniform height, providing a polished and attractive appearance.

4. Improves Mulching: When you mow frequently, the grass clippings are physically smaller and decompose more quickly, returning valuable nutrients to the soil and the plant more efficiently. Although you might associate a higher frequency of cutting with more effort, keeping your grass at a manageable height reduces cleanup. Less volume of plant material being removed reduces clipping clumps and, if you are bagging clippings, reduces the amount you have to dump.

How Often Should You Mow?

The frequency of mowing depends on several factors that aren't as clear-cut as some would suggest. It might be tempting to decide how frequently you cut your turf based on the type of grass or the season. I'd recommend a more property-specific approach that requires you to learn your turfgrass system. At the end of the day, growth rate is key.

Growth Rate: Now we will explore growth rate in higher detail in other articles, but for now, think of the term literally. It is the speed at which your system is growing. Depending on your fertility inputs, sunlight, heat, water, etc, this growth rate will change. Your goal should be to mow at a frequency that matches this growth rate! If your turfgrass is growing like crazy, you should be cutting it almost every day! Keep in mind the rule of one-third discussed above; we want to keep our turf at a manageable height. What if your turf isn't growing like crazy? This is where you'll have to be a bit more careful. If your growth rate is slow, it means recovery to wear is slow as well. Mowing at a high frequency when your system is growing slowly could cause mechanical damage, and you might see signs of thinning turf, weed encroachment, etc.

Your Sweet Spot: Generally, you can expect a higher growth rate in your shoulder seasons if you're growing cool-season turf, as this is when temperatures are more optimal, and the heat of the summer hasn't stressed the grass out yet. Warm-season turf is another animal, where you can expect a higher growth rate in the heat of the summer and lower in the shoulder seasons as temperatures drop. Your job as a property manager is to watch your turf and cut at a frequency that balances mess from the process of cutting and limits the possibility of mechanical wear. It's really that simple.

The Importance of Mowing Direction

Changing the direction of your mowing pattern each time you mow is very important. Here’s why:

1. Prevents Ruts and Soil Compaction: Mowing in the same direction every time can create ruts and compact the soil from your mower, mainly if you're using a push mower or a ride-on with wheels. Alternating directions helps distribute the weight of the mower more evenly over time and prevents soil compaction.

2. Encourages Upright Growth: Grass tends to lean in the direction it is mowed. By changing the mowing pattern, you encourage the grass to grow upright, resulting in a more uniform and aesthetically pleasing turfgrass. Now there is room to "burn in" your lines for specific reasons that we will discuss elsewhere.

3. Reduces Wear and Tear: Consistently mowing in the same direction can cause uneven wear on your mower blades and deck. Switching up your mowing pattern helps distribute the wear more evenly, prolonging the life of your machine.

Best Practices for Mowing Direction

To maximize the benefits of alternating mowing patterns, consider the following tips:

• Rotate the Pattern: Alternate between vertical, horizontal, and diagonal mowing patterns. This ensures that the grass grows upright and reduces the risk of compaction and ruts.

• Overlap Slightly: When changing directions, make sure to overlap each pass slightly to ensure you’re not missing any spots. This technique helps maintain a uniform height across the lawn and minimizes unsightly "mowhawks".

• Be Mindful of Obstacles: If your lawn has trees, garden beds, or other obstacles, plan your mowing pattern to navigate around these areas efficiently. This may involve creating a perimeter pass and then filling in the interior with your chosen pattern.

Conclusion

Mowing frequency and direction play crucial roles in maintaining a healthy and attractive lawn. By mowing regularly and alternating your mowing patterns, you can promote thicker grass, prevent soil compaction, and enhance the overall appearance of your turf. Remember, a little extra attention to your mowing routine can go a long way in ensuring your lawn remains the envy of the neighbourhood.
