How Often To Water Indoor Plants?
Most indoor plants need water every 1 to 2 weeks, but it depends on the plant, light and season. Learn the simple soil check that works for all of them.
Most indoor plants need water every 1 to 2 weeks, when the top inch or two of soil is dry. Succulents can go 2 to 4 weeks, while ferns and seedlings want water every few days. In winter, most houseplants need about half as much water as in summer.
A starting point, not a rule. Check the soil before each watering and stretch the gap in cool, cloudy weather.

More houseplants die from too much water than from too little. The urge to care for them often turns into watering on a schedule, whether they need it or not.
Indoor plants grow slower than garden plants, sit in pots with limited soil, and get less light. That means they drink less. Your job is to water each plant thoroughly when its soil is dry, then leave it alone until it is dry again.
Indoor plant watering schedule
| Type of plant | How often |
|---|---|
| Succulents and cacti | Every 2 to 4 weeks |
| Snake plants and ZZ plants | Every 2 to 4 weeks |
| Pothos, philodendron, monstera | Every 1 to 2 weeks |
| Peace lilies and calatheas | About once a week |
| Ferns and herbs on a windowsill | Every 2 to 4 days |
These are summer ranges. In winter, stretch each one by about half, because shorter days slow growth.
How to tell when indoor plants need water
Push a finger into the soil up to the second knuckle. For most leafy houseplants, water when the top 1 to 2 inches feel dry. For succulents, wait until the pot is dry all the way through.
Lifting the pot works well too. Dry soil weighs much less than wet soil, and you will soon learn each plant by feel.
How to water indoor plants
- Water thoroughly. Pour slowly over the whole soil surface until water runs out of the drainage hole.
- Drain completely. Empty the saucer or cachepot after 15 minutes.
- Use room temperature water. Most tap water is fine. Let it stand overnight if your plants get brown tips.
- Water in the morning. Plants use water during the day, and the soil surface dries faster.
Signs of overwatering and underwatering
Too much water
- Yellow leaves, especially lower ones
- Soil that stays wet for over a week
- Fungus gnats around the pot
- Soft stems or a musty smell
Too little water
- Drooping, soft leaves
- Crispy brown tips and edges
- Soil pulling away from the pot
- Water rushing straight through the pot
Pot, light and season change everything
The same plant can need water every 5 days in a sunny window and every 3 weeks in a dim hallway. Terracotta dries faster than plastic. A small pot dries faster than a big one. A home with the heat on in winter dries soil faster than a cool one, even though plants grow less.
That is why the soil check always beats a calendar. For plant-specific advice, see our guides to monstera, succulents and snake plants.
Indoor Plants watering FAQ
Should I water indoor plants every day?
No. Very few houseplants need daily water. Most need it every 1 to 2 weeks, once the top of the soil is dry.
How much water should I give a houseplant?
Enough that water runs out of the drainage hole. Small sips leave the lower roots dry while the top stays wet.
Do indoor plants need less water in winter?
Yes. Shorter days slow growth, so most houseplants need about half as much water from late fall to early spring.
