I seldom water except for very young plants, and extreme dry conditions. I don’t have a sprinkler on the property, and consider them inefficient and not very effective, except for watering grass. I never water grass. To inhibit moisture loss from hot Sun evaporation all areas of the garden are mulched with wood chips.
Usually I utilize my four barrels of rain water. The wheelbarrow is used to transport the rainwater to the garden area, utilizing a milk cartoon carrier(or egg carton carrier)as a baffle to prevent spillage due to wave action when moving the wheelbarrow.
In extreme dry conditions it is necessary to use tap water.The tap water is delivered to the plant root system using a water wand cut off and pushed into the requires area. I call it the Magic Water Wand. In the main garden it is quick to walk along a row and push the wand into the ground every few feet and get the water to roots, where it is required.The foliage is not wetted, and there is little wastage of water.
