To make St. Augustine grass greener and fuller, you can follow these steps:
1. Water properly: Water deeply and infrequently to encourage deeper root growth. Aim for about 1 inch of water per week, including rainfall.
2. Fertilize regularly: Use a slow-release nitrogen fertilizer in spring, summer, and fall. Follow the package instructions for the correct application rate.
3. Mow at the right height: Keep the grass at a height of about 3.5 to 4 inches. Never remove more than one-third of the grass blade in a single mowing.
4. Control weeds: Use pre-emergent herbicides in early spring to prevent weed seeds from germinating. Spot-treat any existing weeds with appropriate herbicides.
5. Aerating and dethatching: Every 2-3 years, aerate the soil to improve air circulation and water penetration. Dethatch if necessary to remove excessive thatch buildup.
By following these steps, you can promote healthier and lusher St. Augustine grass.
St. Augustine grass prospers in warm and moderate climates that have enough water and regular feeding. To maintain the turf’s green and lush look, it requires weekly maintenance to optimize the growing conditions and encourage robust growth. When the grass is underwatered, overmowed, or grown in deep shade, it can become thin and weak.
Step 1
Provide the St. Augustine grass with full sun, lightly filtered shade, or partial daily shade exposure. Trim or thin out overhead branches and plants to increase sunlight to the area.
Step 2
Water the grass regularly and deeply to keep the soil and thatch below it moist at all times, but not consistently wet. Apply at least 1 inch of water each week for average climates and soil conditions. In hot or dry climates or when growing the grass over sandy, fast-draining soil, apply more water more frequently. Water the soil once or twice per week, drenching it 4 to 6 inches deep to keep the root zone well-hydrated.
Step 3
Mow the St. Augustine grass at the ideal height for the species to maintain the optimal green look and lush feel. Keep the grass between 1 and 3 inches high. The greener the grass will appear, and the softer it will be underfoot, the longer the length. Keep the grass at 3 inches high when growing in shady conditions.
Step 4
Fertilize the lawn once a month from spring through fall with a complete lawn fertilizer. Apply it evenly over the lawn according to the manufacturer’s recommended rate for your soil content. Do not exceed 1 lb. of actual nitrogen for every 1,000 sq. ft. of lawn turf each month, or excess thatch and weak growth can result. Water the fertilizer well to wash the grains down to the thatch and into the root zone. Drench the soil at least 4 inches down after feeding.
Step 5
If the St. Augustine grass is growing over alkaline or iron-depleted soil and turning yellow, spray it with an iron sulfate or chelate foliar supplement to correct the nutrient deficiency and boost the green color in the blades. Apply it according to the product label directions. Repeat this as needed and recommended throughout the growing season.
