How can I effectively remove grass from a flower bed?

To effectively remove grass from a flower bed, you can use a garden shovel or a hand trowel to dig out the grass roots. Make sure to remove as much of the root system as possible to prevent regrowth. You can also use a garden hoe to cut through the grass and then pull it out by hand. Applying a layer of mulch after removing the grass can help prevent it from growing back.
