How Often To Water Potted Plants?
Outdoor potted plants need water every 1 to 2 days in summer, and indoor pots about every 1 to 2 weeks. Learn how pot size and material change the answer.
Water outdoor potted plants every 1 to 2 days in summer, and daily for small pots in full sun. Indoor potted plants usually need water every 1 to 2 weeks. In every case, water when the top inch of soil is dry, and keep going until water runs out of the drainage hole.
A starting point, not a rule. Check the soil before each watering and stretch the gap in cool, cloudy weather.

A plant in a pot lives on whatever water you give it. There is no deep soil to fall back on and no rain that reaches it under a porch roof.
That is why pots dry out much faster than garden beds. A small pot on a sunny patio can go from wet to bone dry in a single summer afternoon. Your job is to check pots often, water them fully, and choose pots that make the job easier.
Potted plant watering schedule
| Where the pot sits | How often |
|---|---|
| Outdoors, full sun, summer | Every day, small pots twice |
| Outdoors, part shade, summer | Every 1 to 2 days |
| Outdoors, spring and fall | Every 2 to 4 days |
| Outdoors, winter | Every 2 to 4 weeks if not frozen |
| Indoors, most houseplants | Every 1 to 2 weeks |
Pot size matters more than anything. A 6 inch pot dries out several times faster than a 16 inch one.
How to tell when potted plants need water
Push a finger about 1 inch into the soil. If it is dry, water. For succulents, wait until the pot is dry most of the way down.
Lift the pot. Wet soil is heavy, and dry soil is light. After a few tries, you will know by feel. Soil that has pulled away from the pot edge is a sure sign it has gone too dry.
How to water potted plants
- Water slowly over the whole surface. Wet all the soil, not just one spot near the stem.
- Keep going until it drains. Water running from the bottom means the whole root ball is wet.
- Rewet dry pots twice. If water rushes straight through, wait 10 minutes and water again, or soak the pot in a bucket.
- Empty saucers. Do not let pots sit in standing water for hours.
Signs of overwatering and underwatering
Too much water
- Yellow leaves with wet soil
- Mold or fungus gnats on the soil
- Soft stems at the base
- A sour smell from the pot
Too little water
- Wilting, especially in the morning
- Crispy brown leaf edges
- Soil shrinking from the pot edge
- Water running straight through
Pick pots that hold water longer
Bigger pots hold more soil and stay moist longer. Glazed ceramic and plastic lose less water than unglazed terracotta, which breathes through its sides. Light colors stay cooler than black pots in full sun.
Use a good potting mix, never garden soil, which packs down hard in containers. Add a layer of mulch on top of outdoor pots. Grouping pots together also helps, because they shade each other.
For houseplants, see our guide to indoor plants. Baskets are covered in hanging baskets, and our bottom watering guide shows how to rewet a pot that has dried out completely.
Potted Plants watering FAQ
Should I water potted plants every day?
Outdoors in summer, often yes. Indoors, almost never. Always check the soil first.
How much water does a potted plant need?
Enough that water runs from the drainage hole. Small sips only wet the top and leave the roots dry.
Do potted plants need water in winter?
Yes, but much less. Outdoor pots need a drink every few weeks when not frozen, and indoor plants about half as often as in summer.
