I am lucky to have my own well and plenty of water.
But that does not mean I waste it.
WE have many flowers and flower gardens and a small veggie garden.
WE much of our watering at late evening and or early morning.
We hand water using a hose and a sprayer.
The water is not shot up in the air to be partially evaporated before it hits the plants.
The water is kept low to minimize the water loss and we water in the wee hours to increase absorption into the soil. Hot soil will also help water to evaporate into the hot are doing no good.
Just a few tips on saving water.
