Plant Watering Amount Calculator
Water your garden the right amount instead of guessing with the hose. Enter the area of the bed or lawn in square feet and the target depth of water in inches per week, and the calculator converts that into gallons, since one inch of water over a square foot is about 0.623 gallons. Most vegetables and lawns want roughly one inch of water a week from rain plus irrigation, so you can subtract recent rainfall to size a top up. Enter your hose or sprinkler flow rate in gallons per minute and the tool also tells you how long to run it to deliver that volume. Deep, less frequent watering builds stronger roots than daily sprinkles. Everything is worked out instantly in your browser with no signup.
