Winterizing Your Lawn: Establishing a Strong Foundation for Optimal Health

As the temperature drops and the days become shorter, winterizing your lawn is essential to ensure its long-term well-being. By taking appropriate measures in late fall and early winter, you can prepare your lawn to withstand the upcoming challenges and rejuvenate itself in the spring.

Winter Care for Your Warm Season Grasses

  • Final Mowing: As winter approaches, gradually increase your mower's cutting height to establish a protective leafy canopy. A 2.5"-3" height is recommended for dense warm-season turf stands.

  • Fertilization: Apply a high-phosphorus fertilizer in late fall to fortify the root system and ready your grass for freezing temperatures. This will also supply essential nutrients for a rapid green-up in spring.

  • Clean-Up: Remove fallen leaves, branches, or other debris from your lawn to prevent moisture accumulation and discourage the spread of diseases and pests.

Spring Care for Your Warm Season Grasses

As winter ends and the first signs of spring emerge, it's time to focus on kickstarting the growth and revitalization of your lawn. Following these steps can create an ideal environment for a lush and thriving landscape.

  • Clean-Up: Remove any fallen leaves, branches, or debris from your lawn to prevent moisture buildup and prevent spreading diseases and pests.

  • Evaluate and Repair Damage: Check your lawn for any damage caused by winter conditions, such as patches of dead grass, compacted soil, or areas lacking vegetation. Repair these areas by overseeding or re-sodding as needed.

  • Scalp Your Lawn: Refer to 'Trim it Up: A Guide for Spring Lawn Scalping' for guidance on removing the warm-season turf grass canopy when the first signs of green appear, resulting in a more uniform and quicker spring green-up.

  • Aeration: Aerating your lawn allows oxygen, water, and nutrients to penetrate deeper into the soil, promoting the growth of stronger roots.

  • Apply Pre-Emergent: In spring, it's recommended to use pre-emergent weed control products to prevent the germination of common weeds like crabgrass and foxtail. Following the instructions on the product's label is crucial for optimal results.

Summer Care for Your Warm Season Grasses

To maintain the health and beauty of your lawn during the summer heat, it is crucial to take extra precautions in response to increasing temperatures and decreased rainfall. By implementing the proper strategies, you can protect your grass from the intense sun and ensure it retains its lush green appearance throughout the season.

  • Watering: Ensure your lawn receives 1/2 inch of water every 7 days. Monitor weekly rainfall totals and supplement rainfall with irrigation. Adopt a deep but infrequent watering philosophy to get the most from your lawn.

  • Adjust Mowing Height: Allow your turfgrass to grow to a canopy height of 2.5 inches and maintain this height. Do not cut off more than 1/3 of the leaf blade of your turfgrass. The added canopy height is recommended to protect your soils from exposure and preserve water.

  • Fertilization: Apply a high-nitrogen fertilizer (ratio 1:0:0, such as a 28-0-0 granular fertilizer). Read the label and apply appropriately, targeting 1/4 - 1/2 pounds of nitrogen per 1,000 square feet of turfgrass every 2 weeks.

  • Monitoring for Pests & Diseases: Watch your lawn for any indications of pests or diseases that may thrive in the summer heat, such as grubs or brown patches. Respond promptly to problems with suitable treatments or consult a professional lawn care service if needed.

Fall Care for Your Warm Season Grasses

As the vibrant colors of fall emerge and temperatures begin to dip, it is essential to shift your attention toward preparing your lawn to withstand the harsh winter months ahead. This involves strengthening roots and protecting plant crowns with a canopy during this time.

  • Fall Pre-Emergent: To effectively prevent the germination of common weeds like henbit, chickweed, and poa annua, it is advisable to apply pre-emergent weed control products during fall. Following the instructions on the product's label is essential for optimal outcomes.

  • Fertilization: To promote strong root growth and encourage lush springtime foliage, choose a slow-release fertilizer specifically formulated for fall with a high phosphorus concentration. Additionally, supplement with potassium fertilizer, as it is essential for fostering healthy root development.


Maintaining a healthy, thriving, and beautiful landscape requires proper lawn care throughout the year. This guide offers seasonal tips that will equip you to handle the challenges that arise with each season and embrace your lawn's growth and development.
