Measuring 1 Inch of Water for Blueberries with a Hose

Goal: moisten soil 6 inches deep once per week. For young blueberries, 5 gallons/week; for 4–6 ft plants, 10 gallons/week if no rain.

Practical Calibration

Time how long your hose takes to fill a 5-gallon bucket. That’s your 5-gallon delivery time. Adjust for plant size and rainfall.

For lawns, use the tuna-can method: stop when 1 inch collects 10 feet from sprinkler.
