How Often Should You Water Houseplants?

The honest answer is 'it depends' — but here are the six variables that actually decide, plus a simple watering routine that works.

Quick answer

There is no universal schedule — most houseplants want a thorough soak when the top 2–3 cm of soil is dry. In a bright, warm room that's roughly weekly; succulents go 2–3 weeks; ferns twice a week. Check with a finger before you water.

There is no universal watering schedule. A weekly reminder is a great way to kill half your houseplants and dehydrate the other half. Water on demand instead — here's how to read demand.

The six variables

  • Species — succulents once every 2–3 weeks, ferns twice a week.
  • Pot size — small pots dry out fast, large pots stay wet.
  • Pot material — terracotta breathes and dries; plastic and glazed pots hold water.
  • Light — more light = more thirst.
  • Temperature and humidity — hot dry rooms drink; cool damp rooms sip.
  • Season — most plants need much less water in winter.

The finger test

Push a finger 2–3 cm into the soil. If it comes out with dry soil clinging or is dust-dry, water. If it's cool and damp, wait 2–3 days and check again. Do this for a month and you'll stop needing to check.

How to water

Water deeply until it runs from the drainage holes, then empty the saucer after 10 minutes. Little sips leave the bottom roots thirsty and the top roots damp.
