As March approaches in South Alabama, it’s time to focus on essential centipede grass maintenance to ensure a lush, healthy lawn throughout the warmer months. Centipede grass, known for its low-maintenance nature and preference for acidic, sandy soils, thrives in the region’s climate. Here’s a comprehensive guide to help you care for your centipede lawn this March.
- Fertilization
March is an ideal time to begin fertilizing your centipede grass as it starts to green up. Opt for a balanced, slow-release fertilizer specifically formulated for centipede grass. Apply approximately 1 pound of nitrogen per 1,000 square feet to promote healthy growth. Be cautious not to over-fertilize, as excessive nitrogen can lead to centipede grass decline.
- Weed Control
Early spring is crucial for pre-emergent weed control. Applying a pre-emergent herbicide in March can help prevent the germination of common weeds like crabgrass and goosegrass. Ensure the product is labeled safe for centipede grass and follow the manufacturer’s instructions carefully. For existing broadleaf weeds, consider a post-emergent herbicide, but avoid using products with high 2,4-D concentrations, as centipede grass is sensitive to this chemical.
- Mowing Practices
As temperatures rise and your lawn begins to grow, establish a regular mowing schedule. Set your mower height to maintain the grass at 1.5 to 2 inches. Avoid cutting more than one-third of the grass blade length in a single mowing session to reduce stress on the turf. Always use a sharp mower blade to ensure clean cuts and minimize disease risk.
- Aeration
Soil compaction can hinder root development and water infiltration. March is an excellent time to aerate your centipede lawn, especially if it’s subject to heavy foot traffic. Core aeration, which involves removing small soil plugs, improves air exchange and nutrient uptake. After aeration, your lawn will better absorb fertilizers and water, promoting robust growth.
- Irrigation
Centipede grass requires about 1 inch of water per week, either from rainfall or supplemental irrigation. In March, monitor rainfall levels and adjust your watering schedule accordingly. Water deeply and infrequently to encourage deep root growth, which enhances drought tolerance. Early morning watering is best to reduce evaporation and prevent fungal issues.
- Monitoring for Pests and Diseases
While centipede grass is relatively resistant to pests and diseases, it’s essential to remain vigilant. In March, inspect your lawn for signs of common issues such as:
- Lawn Burweed: This invasive weed germinates in the fall and becomes noticeable in early spring. Applying a post-emergent herbicide before the plant sets seed can help control its spread.
- Fungal Diseases: Conditions in early spring can favor diseases like large patch. Ensure proper watering practices and consider fungicide applications if you notice symptoms.
By addressing these key areas in March, you’ll set the foundation for a healthy and vibrant centipede lawn in South Alabama. Consistent care and attention to seasonal needs will ensure your lawn remains a source of pride throughout the year.
