How can I effectively manage and control spiky grass in my lawn?

To effectively manage and control spiky grass in your lawn, you can regularly mow your lawn at a higher setting to prevent the spiky grass from growing too tall. Additionally, you can manually remove the spiky grass by hand or use a selective herbicide specifically designed to target spiky grass while sparing the rest of your lawn. Regular maintenance and monitoring of your lawn can help keep spiky grass under control.
