How to Use the Watering Frequency Calculator
Choose your plant, enter the pot diameter in centimetres, then pick the current season and the light level where the plant sits. Press Calculate and the tool suggests how many days to leave between waterings. Use Clear to reset the form.
What the result means
The number is a starting interval, not a fixed rule — always check the soil before watering.
Smaller pots dry out faster, so they get a shorter interval.
Plants drink more in summer and in brighter light, so the interval shortens.
The suggested range shows a sensible upper and lower bound around the estimate.
