How to Use This Calculator
- Select your primary plant type — fruiting vegetables, leafy greens, herbs, etc. — to set the base weekly water need.
- Choose your soil type (sandy, loam, clay, or silt) so the calculator can adjust frequency; sandy soil drains fast and needs more frequent watering.
- Select your sun exposure and climate zone to account for evaporation differences.
- Enter your garden area in square feet to convert inches of water into gallons.
- Review the Gallons per Week, number of watering sessions, and minutes per session for your irrigation method (hose, sprinkler, or drip).
- Use the estimated Monthly Water Cost to budget your seasonal irrigation expenses.
