Steps to Successfully Mix Bermuda Grass with St Augustine

Choose the Right Time for Seeding

The best time to plant both grasses is during late spring or early summer when soil temperatures are warm. This ensures rapid germination and establishment. Avoid planting during colder months to prevent poor growth or failure.

Prepare the Soil Properly

Start by testing your soil to determine pH and nutrient levels. Both grasses prefer well-drained soil with a pH between 5.5 and 7.5. Incorporate organic matter to improve fertility and ensure even seed or sod placement.

Decide on the Planting Method

For Bermuda grass, sod or sprigs work best for quick coverage. For St Augustine, sod is commonly preferred but sprigs can be used for cost-effective expansion. Combining sod with sprigs can optimize growth and cost-efficiency.

Plant with Precision

Lay sod in a staggered pattern to minimize gaps. When planting sprigs, space them about six inches apart and press them firmly into the soil. Maintain consistent moisture to promote healthy rooting.

Water and Fertilize Correctly

Water the newly planted area deeply two to three times weekly, keeping the soil moist but not waterlogged. Fertilize with a balanced fertilizer formulated for warm-season grasses to support growth and color.

Managing the Mixed Lawn

Adjust Mowing Heights

Bermuda grass should be mowed at approximately one to one and a half inches. St Augustine prefers a slightly higher height, around two to three inches. Adjust your mower to suit each grass type, or mow selectively.

Fertilization Schedules

Apply nitrogen-rich fertilizers every six to eight weeks during the growing season. Use different fertilizers if needed to meet the specific requirements of each grass type.

Controlling Weeds and Pests

Regularly inspect your lawn for invasive weeds or pests. Use appropriate herbicides and pest control methods that are safe for both Bermuda and St Augustine grasses. Proper maintenance reduces the chance of weed invasion.

Dealing with Shade and Sun Areas

Identify shaded areas where St Augustine excels and ensure they are not overrun by Bermuda grass, which prefers full sun. Conversely, keep Bermuda in sunnier zones for optimum health. This zonal approach ensures both grasses thrive.

Challenges When Mixing Bermuda Grass with St Augustine

Incompatibility in Growth Rates

Bermuda tends to grow faster and can overshadow St Augustine if not managed properly. Regular mowing and edging can help balance their growth.

Different Watering Needs

While both grasses prefer similar watering schedules, Bermuda may require more water during peak heat. Adjust watering practices accordingly for each zone.

Color and Texture Disparities

The visual difference between the fine Bermuda blades and the coarse St Augustine can be noticeable. Regular maintenance can help blend the appearance for a more uniform look.

Maintaining a Mixed Bermuda and St Augustine Lawn

Regular Mowing and Edging

Maintain the right mowing height for each grass type to prevent one from dominating the other. Edging along borders keeps the grasses separate and tidy.

Consistent Fertilization

Apply the correct type and amount of fertilizer at the right times to support healthy growth. Avoid over-fertilizing to prevent thatch build-up or excessive growth.

Proper Aeration and Overseeding

Aerate the soil annually to reduce compaction and improve nutrient absorption. Overseeding can help fill in bare patches and maintain a lush appearance.

Addressing Thatch and Pests

Remove excess thatch to improve water and nutrient penetration. Use pest control methods as needed to prevent damage from insects or diseases.
