Fall Watering & Mowing Tips

After a long hot summer in Knoxville, TN, our lawns are feeling relieved as we head into fall. Our lawns can now start to recover from the heat and drought stress they sustained over the past several months. It is imperative that homeowners follow an appropriate watering and mowing regimen in the fall to ensure their lawns come back healthier and better than ever when it really counts.

Fall Watering Tips

The golden rule of thumb is that your lawn requires 1 inch of water per week to remain healthy. Typically during the fall there is an increase in rainfall, meaning you should cut back on your watering practices accordingly. Overwatering your lawn can result in lawn diseases. The best time of day to water your lawn is in the morning, as this helps delay evaporation and encourages full water penetration down to the grass roots. Deep and infrequent watering is best – do not water your lawn every 1-2 days for short intervals. It is better to water your lawn every 3-4 days or as needed based on the weather conditions.

Fall Watering Tips Recap:
  • Ensure your lawn receives 1 inch of water per week
  • Monitor rain levels and adjust watering accordingly
  • Water in the mornings
  • Do not over water your lawn
  • Deep and infrequent watering is best

Fall Mowing Tips

During the summer you may have noticed that your lawn was not growing as quickly. Now that fall is here, the increase in rainfall will spike growth and call for increased mowing frequency. This is a good sign that your lawn is recovering from a dormant state. When mowing your lawn, you should never cut off more than 1/3 of the grass blade. It is also essential that you sharpen your mower blade (at least once per year), as this creates a clean cut and builds resiliency against disease. When it comes to mowing height, St.Augustine grass should be cut at 3 inches tall all year, no exceptions. Bermuda and Zoyisa grass should both be cut at around 2.5 inches tall during the fall and winter to cover the soil from direct sunlight. If cut too short, your lawn will be at risk for weed outbreaks.
Fall Mowing Tips Recap:
  • Increase mowing frequency
  • Never cut off more than 1/3 of the grass blade
  • Mow at the right height
  • Sharpen your mower blade
