A quick tip on watering your garden: pay attention to what you are doing. Waving the hose about, spraying everything with a nice, light shower is both barely helpful for the plant and a great waste of time and water. Water sprayed about lightly does not penetrate to the roots of a plant, it mostly sits on the leaves and surface of the soil or mulch and then evaporates.
If you are going to water, pay attention; aim a steady flow of water to the roots of each plant for enough time for the water to sink deeply into the soil around the root system - this could be several seconds per plant. If you water each plant long and deep, you will only need to water every few days rather than every day.
