Question 1

How much water does my houseplant need?

Accepted Answer

As a rough rule, give about 10–20% of the pot volume each time. A 6-inch pot (about 1 liter of soil) needs 100–200 ml. The exact amount depends on the plant type, pot size, light and humidity — our calculator does the math for 50+ common plants.

Question 2

How often should I water my plants?

Accepted Answer

Most houseplants like the top inch of soil to dry between waterings. Tropical foliage plants (monstera, pothos) average every 7–10 days, succulents every 14–21 days, and cacti every 3–4 weeks. Frequency increases in summer and bright light, and drops in winter.

Question 3

What is the best way to know when to water?

Accepted Answer

Stick your finger 1–2 inches into the soil. If it feels dry at that depth, water deeply until it runs out the drainage hole. A cheap moisture meter works too. The schedule from this tool is a starting point — always verify with the finger test.

Question 4

Should I water more in summer?

Accepted Answer

Yes. Warm temperatures, longer days and active growth mean plants drink faster. The calculator has a season selector that adjusts the watering interval — summer is typically 30–40% more frequent than winter for most houseplants.
