Centipede Grass: The Basics

Centipede grass, scientific name Eremochloa ophiuroides, is a durable warm-season turfgrass well-suited to certain regions in the South, including South Carolina. It displays a medium texture and light green coloration, distinguishing it from other lawn grass species which are often darker green.

Developing an understanding of this grass’s growth habits and preferences helps ensure a healthy and attractive lawn.

Centipede grass grows close to the ground and is notable for its slow growth rate and low fertility requirements, which contribute to its characterization as a low-maintenance option for homeowners.

Soil Preferences:

  • pH Levels: Thrives in slightly acidic soil with pH between 5.5 and 6.0.
  • Soil Type: Adaptable but often flourishes in sandy or clay soils.

Climatic Suitability:

  • Heat Tolerance: Excels in warm climates.
  • Cool Weather: Growth diminishes and may go dormant in cooler temperatures.

Owners of centipede grass lawns often appreciate its minimal upkeep demands. Unlike other more needy turfgrasses, it does not demand frequent mowing or high doses of fertilizer.

Careful management, particularly regarding water, fertilization, and mowing height, can prevent problems such as thatch buildup, scalping, and disease vulnerability.

The grass’s adaptability to the coastal plains and midlands of South Carolina makes it an excellent choice for a sustainable and low-input lawn in these areas.

Proper care and regular maintenance tailored to centipede grass’s unique needs will promote a vigorous and resilient turf.

Optimal Planting Time in South Carolina

The success of Centipede grass in South Carolina hinges on proper planting during the two key growth periods—spring and fall.

Spring Planting Guidelines

In South Carolina, spring is the prime season for planting Centipede grass.

One should ideally initiate planting procedures once the threat of frost has passed and soil temperatures consistently reach 70°F. This typically occurs between April and June.

  • Soil Preparation: Ensure the soil is tilled and free from debris and weeds.
  • Seed Sowing: Evenly spread the Centipede grass seeds across the prepared soil.
  • Watering: After planting, provide the lawn with 1 inch of water per week to maintain moist conditions conducive to seed germination.

Fall Considerations

Planting Centipede grass in the fall should be approached with caution.

Specifically, if planting is to be done, it should take place well before the first predicted frost date to allow the grass sufficient time to establish.

However, in South Carolina, with its milder climate, the window for fall planting is narrow and generally not recommended due to the slower growth rate and increased vulnerability to winter kill.

  • Soil Temperature: Maintain a close watch as cooler temperatures can lead to poor seed germination.
  • Weed Competition: Fall planting may have an increased chance of weeds, which can be detrimental to young Centipede grass.

Soil Preparation for Centipede Grass

Before planting centipede grass in South Carolina, one must ensure the soil is properly conditioned to promote optimal growth.

As a warm-season turfgrass, centipede grass thrives in acidic soils with a pH ranging from 5.5 to 6.0. South Carolina’s coastal plains often exhibit a higher pH, necessitating soil amendments.

Soil pH Adjustment:

  • Test Soil: Begin with a soil test to determine the current pH level.
  • Add Sulfur: If the pH exceeds 6.0, incorporate pelletized sulfur to lower it. Use at a rate of 5 pounds per 1000 square feet.

Soil Texture and Nutrients:

  • Loosen Soil: Cultivate the soil to a depth of 4 to 6 inches. This improves root penetration and water drainage.
  • Organic Matter: Amend with organic material like compost to enrich the soil if necessary.

Final Preparations:

  1. Level the Ground: Smooth the soil to eliminate bumps and depressions.
  2. Dethatch: For an existing lawn, dethatch if the layer exceeds ¼ inch to prevent soil compaction and to aid in nutrient and water absorption.
  3. Moisture: Ensure the soil is lightly moist before planting the grass seed.

Fertilization Schedule

Proper fertilization is crucial to maintain the health and vibrant green color of centipedegrass in South Carolina. Homeowners should adhere to a specific schedule to promote robust growth without increasing the risk of disease or pests.

Initial Fertilization

  • Timing: The initial fertilization should occur only after the soil temperature consistently reaches 65°F at a 4-inch depth. This typically happens in late spring.
  • Product Choice: Homeowners are advised to use a complete turf fertilizer based on the results of a soil test.
  • Application Rate: Generally, 1 pound of nitrogen per 1,000 square feet is recommended for the first application to avoid excessive growth.

Maintenance Fertilization

  • Frequency: Subsequent fertilizations should be limited to 1 to 2 pounds of nitrogen per 1,000 square feet annually, to prevent overfertilizing.
  • Timing: Apply maintenance fertilizer from mid-May onward; never before.
  • pH Balance: Maintain soil pH between 5.5 to 6.0, applying sulfur to lower the pH if necessary, according to soil test results.
  • Avoid Phosphorus: Utilize phosphorus-free fertilizers to maintain proper iron levels, such as a 15-0-15 blend.

Watering and Care Post-Planting

Once centipede grass is established, appropriate watering and maintenance ensure the health and beauty of the lawn.

Initial Watering:

  • Watering should commence immediately after planting.
  • For the first three weeks, maintain consistent moisture in the soil to encourage root development.

Established Lawn Irrigation:

  • Centipede grass needs about 1 inch of water per week, from rainfall or irrigation.
  • Watering is best done early in the morning to reduce evaporation and fungal diseases.

Monitoring:

  • Observe the lawn for signs of drought stress, such as wilting or graying blades.
  • Only water when these signs are apparent to promote deep rooting and drought tolerance.

Aftercare:

  • The first mowing should occur 2-3 weeks after planting when the grass is well-rooted.
  • Raise the mowing height during droughts or hot weather to reduce stress on the lawn.

Avoid Overwatering:

  • Excessive moisture can lead to disease and hinder deep root development.
  • Ensure proper drainage to prevent waterlogging.
