A practical care tool

Houseplant Watering Calculator

Build a seasonal starting point for how often to check your plant and how much water to begin with. The soil condition—not the calendar—makes the final call.

Your seasonal plan

Your plan will appear here.

Choose a plant, pot and light setting to create a seasonal soil-check rhythm and starting water amount.

Use the result as a care rhythm

The number is a reminder to check the soil, not a fixed watering appointment. Let the plant and pot make the final call.

01

Check first

Use the soil test shown for your plant before adding water.

02

Water slowly

Start with the suggested amount around the root zone.

03

Stop at drainage

Empty the saucer or cachepot after light drainage appears.

This tool assumes a healthy plant in a draining pot with ordinary indoor conditions. Persistently wet soil, pests, or root-rot symptoms need diagnosis rather than more water.
