Dew on the grass in the morning

As the summer heat begins to wane and the days grow shorter, September offers a fantastic opportunity to give your lawn the extra attention it needs to thrive.

This month is a pivotal time in your lawn care routine, as it sets the stage for a beautiful, healthy yard come spring. In this special September edition of Lawn Specialties, we’ll explore essential tips and tasks to ensure your lawn remains vibrant and lush throughout the fall and beyond.

Lawn Aeration

One of the key tasks in September is lawn aeration. Aeration involves perforating the soil with small holes to allow better airflow, nutrients, and water absorption. This process alleviates soil compaction, which can restrict root growth. Rent an aerator or hire a professional service to help with this task.


After aerating, it’s the ideal time to overseed your lawn. Overseeding fills in thin or bare patches and encourages new grass growth. Choose a high-quality grass seed that suits your region and climate, and spread it evenly across your lawn. Ensure proper watering for successful germination.


Fertilizing in September is crucial for preparing your lawn for the upcoming winter months. Look for a balanced, slow-release fertilizer with a higher ratio of potassium to help strengthen the grass’s root system. Apply according to package instructions, typically during the first half of the month.

Pest and Weed Control

Weeds and pests can be persistent even as the weather cools down. Use this time to tackle any weed issues and keep an eye out for signs of pests such as grubs. Choose environmentally friendly control methods whenever possible to minimize harm to beneficial insects and wildlife.


Continue to mow your lawn regularly but adjust the cutting height as needed. As temperatures cool, raise the mower blade to a higher setting to leave grass longer. This helps shade the soil, reduce evaporation, and promote deeper root growth. Remember the one-third rule: never cut more than one-third of the grass height at a time.


Adjust your watering schedule to accommodate the changing weather. In many regions, September brings cooler and more unpredictable conditions. Monitor rainfall and soil moisture to avoid overwatering or allowing your lawn to dry out. Deep, infrequent watering is generally preferable to frequent shallow watering.

Fall Cleanup

Regularly remove fallen leaves and debris from your lawn to prevent mold growth and keep the grass healthy. You can use a mulching mower to shred leaves into small pieces that will break down and provide nutrients to the soil.

September is a pivotal month for lawn care, setting the stage for a lush and vibrant yard in the coming seasons. By following these essential tips, you’ll ensure that your lawn is well-prepared for the fall and winter ahead. Take advantage of the cooler weather to rejuvenate your lawn, and you’ll be rewarded with a healthy, resilient yard that’s the envy of the neighborhood.
