by

March is an ideal time to start preparing your St. Augustine grass for the warmer months ahead, especially in Zone 10 where the climate remains mild. Proper care during this period ensures a lush, healthy lawn throughout the season.

Understanding Your Zone 10 Climate

Zone 10 features warm temperatures year-round, with minimal frost. This allows for year-round growth and maintenance of your St. Augustine grass, but also requires specific care to prevent problems like overwatering or fungal diseases.

March Lawn Care Tips for Zone 10

1. Mowing

Maintain a mowing height of about 2.5 to 4 inches. Regular mowing encourages healthy growth and prevents thatch buildup. Be sure to sharpen your mower blades for a clean cut.

2. Watering

Water your lawn deeply once or twice a week, depending on rainfall. Early morning is the best time to water to reduce evaporation and fungal issues. Avoid overwatering, which can lead to root rot.

3. Fertilizing

Apply a balanced, slow-release fertilizer formulated for warm-season grasses. Follow the recommended application rates and avoid fertilizing during periods of drought or stress.

4. Aeration and Dethatching

March is a good time to aerate your lawn to improve soil compaction and promote root growth. Dethatch if the thatch layer exceeds 0.5 inches to enhance nutrient and water penetration.

Managing Pests and Diseases

Keep an eye out for pests like chinch bugs and grubs, as well as fungal diseases such as brown patch. Use appropriate treatments promptly and maintain good lawn hygiene to prevent infestations.

Additional Tips for a Healthy Lawn

  • Remove debris and fallen leaves regularly.
  • Maintain proper pH levels by testing soil and adjusting as needed.
  • Limit foot traffic on damp lawns to prevent compaction and damage.
  • Consider overseeding if your lawn has thin or bare patches.

By following these care tips in March, your St. Augustine grass in Zone 10 will stay vibrant and healthy throughout the warmer months. Consistent maintenance is key to a beautiful lawn all year round.
