Prevention Strategies
Regular mowing helps keep Bermuda grass at bay. Keep your lawn at a height of 3 to 4 inches. This height prevents Bermuda grass from getting enough sunlight. Water your lawn deeply but infrequently. Deep watering encourages strong root growth in St Augustine grass. Avoid over-fertilizing as it can promote Bermuda grass growth. Use a slow-release fertilizer for best results. Ensure your mower blades are sharp. Dull blades can damage grass and make it vulnerable to weeds.
Healthy soil is crucial for a robust lawn. Test your soil’s pH levels regularly. St Augustine grass thrives in slightly acidic to neutral soil. Add lime if your soil is too acidic. Use sulfur if it’s too alkaline. Organic compost improves soil structure and fertility. It also helps in water retention. Aerate your lawn to reduce soil compaction. Compacted soil makes it hard for grass roots to grow strong. Mulching can help retain moisture and add nutrients to the soil.

Manual Removal Techniques
Hand-pulling is a simple method to kill Bermuda grass. Start by watering the area to soften the soil. This makes it easier to pull out the grass. Wear gloves to protect your hands. Grasp the Bermuda grass firmly and pull it out, including the roots. Roots left in the soil can regrow. Be thorough to ensure the grass does not return.
Garden tools can help remove Bermuda grass effectively. A spade or shovel works well for this task. Insert the tool into the soil around the Bermuda grass. Lift the grass, including the roots, out of the soil. A hoe can also be used to slice through the roots. Ensure all roots are removed to prevent regrowth. Regular inspection of the area helps keep Bermuda grass at bay.
Chemical Control Methods

Apply herbicides on a calm day. Windy conditions can cause drift and damage other plants. Use protective gear such as gloves and goggles. Water the area well before application. This ensures the herbicide reaches the roots. Reapply if necessary, following label directions. Keep pets and children away until the area is dry.
