Frequently Asked Questions
How is this watering estimate calculated?
It combines your bed's square footage with adjustment factors for soil drainage, sun exposure, plant type, and temperature to estimate total weekly water demand.
Does this account for rainfall?
No, this estimates irrigation needs assuming no significant rainfall. Subtract recent rainfall totals from the weekly total for a more precise number.
Why does soil type matter so much?
Sandy soil drains quickly and needs more frequent, lighter watering, while clay retains moisture longer and needs less frequent but deeper watering.
