How can I effectively water my lawn without a sprinkler system?

To effectively water your lawn without a sprinkler system, you can use a hose with a sprinkler attachment or a watering can to evenly distribute water. Make sure to water deeply but infrequently to encourage deep root growth, and water in the early morning or late evening to reduce evaporation. Additionally, consider using a soaker hose or drip irrigation system for more efficient watering.
