Make your own rain gauge and track how much rain falls in your backyard. On average, a vegetable or flower garden or lawn needs about 3 cm of rainfall per week. Look at your rainfall records. Is your garden getting enough water? If not, a rain gauge can help you decide if you need to water your garden with a hose.
