How can I effectively de-weed my lawn to maintain its health and appearance?

To effectively de-weed your lawn and maintain its health and appearance, you can manually remove weeds by hand or use a tool like a weeder or hoe. You can also use herbicides specifically designed for lawns, following the instructions carefully to avoid harming your grass. Regularly mowing your lawn at the proper height and watering deeply but infrequently can also help prevent weeds from taking over.
