How Often To Water Ferns?
Water ferns 2 to 3 times a week in summer to keep the soil lightly moist, and less in winter. Learn how to stop crispy fronds and dropping leaves.
Water indoor ferns 2 to 3 times a week in warm months, whenever the soil surface starts to feel dry. In winter, about once a week is usually enough. Ferns want soil that stays lightly moist all the time, so never let a fern dry out completely.
A starting point, not a rule. Check the soil before each watering and stretch the gap in cool, cloudy weather.

Ferns are the opposite of succulents. They do not want to dry out, ever, and they will tell you within a few days if you let them.
Most ferns grown indoors, like Boston ferns and maidenhair ferns, come from shady forest floors where the soil stays damp and the air is humid. Their roots are fine and shallow. Your job is to keep the soil lightly moist, like a wrung out sponge, and give them some humidity.
Fern watering schedule
| Conditions | How often |
|---|---|
| Hanging basket, summer | Every day or every other day |
| Pot indoors, spring and summer | 2 to 3 times a week |
| Pot indoors, winter | About once a week |
| Outdoors in a shade bed | 1 to 2 times a week without rain |
Heating vents and sunny windows dry ferns fast. Keep them in bright, indirect light away from radiators.
How to tell when ferns need water
Touch the surface of the soil. When it starts to feel dry, it is time. You do not need to wait for the soil to dry deeper down, as you would with most houseplants.
The fronds give early hints. They look slightly dull and lose their bounce when thirsty. If you see crispy brown tips or tiny leaflets falling, the fern has already been too dry for too long.
How to water ferns
- Water until it drains. Pour slowly over the soil until water runs from the bottom.
- Empty the saucer. Ferns like moisture, not standing water.
- Soak hanging baskets. If the basket dries out completely, set it in a bucket of water for 20 minutes.
- Use room temperature water. Rainwater or water left out overnight is ideal for sensitive types like maidenhair.
Signs of overwatering and underwatering
Too much water
- Yellow fronds, often at the center
- Soggy soil with a sour smell
- Gray, mushy crown at the base
- Fungus gnats around the pot
Too little water
- Crispy, brown frond tips
- Tiny leaflets falling all over the floor
- Fronds turning pale and gray green
- Soil shrinking from the pot edge
Humidity matters as much as water
Many ferns struggle indoors not because of the soil, but because of dry air. A heated home in winter can be drier than a desert. Even with perfect watering, fronds can crisp up.
Group ferns with other plants, use a pebble tray, or run a small humidifier nearby. Bathrooms with a bright window make great fern spots. Misting helps only briefly and is not a replacement for any of these.
Ferns pair well with the peace lily, another moisture lover. For the rest of your plants, see our guide to watering indoor plants.
Ferns watering FAQ
Should I water my fern every day?
Only ferns in hanging baskets or very warm spots. Most potted ferns need water 2 to 3 times a week in summer.
Why are my fern leaves turning brown and crispy?
Usually dry soil, dry air, or both. Water as soon as the surface feels dry and add humidity with a pebble tray or humidifier.
Do ferns like to be misted?
Misting gives a short boost, but it dries within minutes. Steady humidity from a pebble tray or humidifier helps far more.
