If your hanging fern is drying out, the cause is usually one of five common issues: underwatering, excessive sunlight, summer heat stress, low humidity, or root problems. Hanging baskets dry out much faster than traditional containers. This is why even healthy ferns can suddenly develop brown fern leaves or crispy foliage during warm weather.
The good news is that you can quickly correct most hanging basket fern problems once you identify the source of the stress. In many cases, adjusting your watering routine and improving growing conditions is enough to restore healthy green growth.

Why Ferns Dry Out Faster in Hanging Baskets
One main reason gardeners have trouble with hanging ferns is that baskets create a different environment than regular pots. This environment affects how the ferns grow.
Air circulates around all sides of the basket, increasing evaporation and causing the soil to lose moisture much faster. Add summer heat, wind, and larger fern varieties into the mix, and a basket that looked perfectly healthy yesterday can suddenly appear stressed today.
This is why hanging basket fern care often requires more attention than caring for ferns planted directly in the ground.
Before you assume your fern is dying, know that many dry symptoms are early warning signs. Catching them quickly often allows the plant to recover completely.
The Most Common Cause: Underwatering
If you're asking, "Why is my hanging fern drying out?" the first thing to check is soil moisture.
Underwatering is responsible for more hanging basket failures than any other issue.
Many gardeners underestimate how much water large ferns need, especially during hot weather. Boston Ferns, Macho Ferns, and mature Kimberly Queen Ferns can use surprising amounts of water once temperatures climb.
Signs of underwatering often include:
- Crispy fern leaves
- Brown leaf tips
- Wilted fronds
- Dry potting soil
- Soil pulling away from the basket edges
The easiest way to diagnose the problem is to check the soil. If the top inch feels dry, your fern likely needs water.

Too Much Sun Can Make a Fern Look Drought-Stressed
Many gardeners are surprised to learn that a well-watered fern can still look dry.
In fact, one of the most common causes of a hanging fern turning brown is excessive sunlight.
Most fern varieties prefer bright indirect light, filtered sunlight, or morning sun rather than harsh afternoon exposure.
When ferns receive too much direct sunlight, they may develop:
- Brown patches
- Faded foliage
- Crispy edges
- Burned fronds
- Dry-looking growth despite moist soil
If your basket sits in direct afternoon sun, consider moving it to a covered porch or a location with filtered light.

Summer Heat Can Cause Ferns to Dry Out Almost Overnight
Even when you're watering correctly, extreme temperatures can create problems.
During prolonged heat waves, hanging baskets often lose moisture faster than roots can absorb it. This is especially true for larger specimens with dense foliage.
Many gardeners see their fern dry out in July and August. This happens even with the same routine that worked in spring.
This doesn't necessarily mean you're doing anything wrong.
Instead, it usually means your fern's water needs have changed.
Watering ferns during summer often requires:
- Daily soil checks
- More frequent watering
- Protection from intense afternoon sun
- Extra attention during windy conditions
A basket that needed water every three days in May may require daily watering by midsummer.
Low Humidity Can Cause Crispy Fern Leaves
Humidity plays a much bigger role in fern health than many people realize.
While outdoor humidity is usually sufficient in many regions, dry conditions can still develop around porches, patios, and covered outdoor spaces.
Low humidity typically causes:
- Crispy fern leaves
- Brown tips
- Dry new growth
- Declining appearance despite adequate watering
This problem becomes even more common when ferns are moved indoors for winter.
Kangaroo Ferns tend to adapt particularly well to indoor conditions compared to some other varieties. For more information, visit our Kangaroo Fern Care Guide.
Why Is My Fern Turning Brown If I Water It Regularly?
This is one of the most common troubleshooting questions.
If you're watering consistently but still seeing brown fern leaves, the issue may not be watering frequency at all.
Instead, consider other possible causes:
- Excessive sunlight
- Poor drainage
- Root crowding
- Fertilizer buildup
- Heat stress
- Low humidity
Many hanging basket fern problems look alike at first. That is why checking growing conditions matters as much as checking soil moisture.
Can Brown Fern Leaves Turn Green Again?
Unfortunately, once a fern frond turns brown, it won't return to green.
However, that doesn't mean you have lost the entire plant.
Most healthy ferns produce new growth and recover after you correct the underlying problem.
If your fern is developing brown foliage:
- Remove completely dead fronds.
- Correct the source of stress.
- Continue normal watering and care.
- Watch for fresh green growth.
New fronds are usually the best sign that recovery is underway.
How to Revive a Hanging Fern
If your fern is drying out, don't panic.
Most plants recover surprisingly well when given proper care.
Start by checking the soil and evaluating the growing environment.
Move the basket if it's receiving too much sun. Water deeply if the root ball is dry. Trim away dead growth and monitor new fronds over the following weeks.
For many gardeners, learning proper hanging basket fern care can turn a struggling plant into a thriving one.

The Bottom Line
If your hanging fern is drying out, the problem is usually moisture-related, but watering isn't always the only culprit.
Underwatering, excessive sun, heat stress, and low humidity can all cause a hanging fern to develop brown foliage and crispy leaves. The key is identifying the source of the problem early and making small adjustments before serious damage occurs.
Most ferns are surprisingly resilient. With proper watering, appropriate light, and consistent care, they often recover faster than many gardeners expect.
