How can I effectively remove spiky grass from my lawn or garden?

To effectively remove spiky grass from your lawn or garden, you can use a shovel or a hand tool to dig out the roots of the grass. Make sure to remove as much of the root system as possible to prevent regrowth. You can also use a herbicide specifically designed to target grassy weeds, following the instructions carefully to avoid damaging other plants. Regularly monitoring and pulling out any new growth can help prevent the spiky grass from spreading.
