How to Kill Bahiagrass: 10 Steps
Bahiagrass (Paspalum notatum) is a tough, deep-rooted perennial grass that can quickly spread and overtake lawns, flowerbeds, and other landscaped areas. While it’s drought-tolerant and hard to kill, you don’t have to let it rule your yard. Here are ten steps to help you get rid of Bahiagrass.
1. Identify the Bahiagrass: Make sure you’re dealing with Bahiagrass by looking for its telltale features like V-shaped seed heads and pale green, thin leaves.
2. Choose the right time: The best time to target Bahiagrass is during its active growing season. In warmer climates, this is usually from late spring through early fall.
3. Mow your lawn: Mow your lawn right before starting the removal process. Cut the grass lower than usual to expose more of the Bahiagrass’ roots and leaves.
4. Apply selective herbicides: Use a selective herbicide specifically formulated for killing Bahiagrass. Check the label to ensure it’s safe for your desired plants and follow the application instructions carefully.
5. Use a non-selective herbicide: If Bahiagrass has infested a non-lawn area or if it’s particularly aggressive, consider using a non-selective herbicide like glyphosate. Be cautious, as this will also kill other plants it comes into contact with.
6. Reapply herbicides as needed: If you see new growth after initial treatment, reapply the herbicide according to the manufacturer’s instructions.
7. Manual removal: In smaller infested areas or if you prefer a chemical-free approach, remove Bahiagrass manually. Dig deep enough to get its entire root system, usually about 4-6 inches below ground level.
8. Solarization: Another eco-friendly option is solarization. Lay a clear plastic sheeting over the infested area, sealing its edges with rocks or soil. Leave it in place for four to six weeks during the hot season to kill Bahiagrass via heat and UV radiation.
9. Adjust your lawn care practices: To prevent Bahiagrass from returning, maintain a thick, healthy lawn through proper mowing, fertilizing, watering, and aerating.
10. Monitor your property regularly: Keep an eye on your lawn and garden for any signs of Bahiagrass reemergence. Address new infestations quickly to prevent them from getting out of control.
By following these ten steps, you’ll be well on your way to defeating Bahiagrass and reclaiming your beautiful outdoor space. Patience and persistence are key – keep up the hard work, and enjoy the results of a Bahiagrass-free yard!
