Why Are My Ferns Turning Brown: Essential Care Tips
Spread the love

If you're asking, "Why are my ferns turning brown?", you've come to the right place. Ferns can turn brown due to various reasons such as low humidity, underwatering, too much sunlight, nutrient deficiency, root rot, or disease. Understanding these factors can help you take better care of your ferns and maintain their lush green appearance.

The most common reasons for ferns turning brown are low humidity and underwatering. Ferns prefer 40% humidity, whereas indoors, the humidity is typically around 10%, which causes the leaves to lose water and turn brown. Underwatering can also cause the leaves to turn brown. Ferns should be watered thoroughly and the soil should be consistently moist (but not saturated). Too much sunlight can also cause the sensitive foliage leaves to turn brown. Ferns are native to living under woodland and forest canopy with only filtered light or full shade. High temperatures can cause the soil and foliage to dry out and turn brown.

There's so much more to learn about fern care! From understanding the right watering schedule to providing the right amount of light, each aspect plays a crucial role in maintaining the health of your ferns. Stay curious and keep learning!

Fern Care Basics

Watering Needs

Regularly check soil moisture to prevent fern dehydration. Adjust watering based on the finger dip test. Use room temperature water for hydration.

Light Exposure

Avoid direct sunlight to prevent browning. Place ferns in shaded areas for vibrant green color. Monitor ferns near windows to prevent drying.

Humidity Levels

Increase humidity through misting or relocation to a humid environment. Watch closely in dry air conditions and provide adequate moisture.

Nutrient Essentials

Maintain balanced nutrients to prevent browning. Use suitable fertilizer for health and vibrancy. Adjust nutrient application based on growth stages.

Identifying Distress Signals

Browning Fronds

Ferns develop browning fronds due to various reasons like insufficient humidity or light exposure. Trim brown fronds at the base using sharp scissors to encourage new growth. Regularly monitor fern fronds for any signs of browning to catch and address issues early. Promptly remove dead or browning fronds to maintain the overall health of your fern plant.

Drooping Leaves

Drooping fern leaves indicate a problem with soil moisture levels. Check the soil moisture by inserting your finger into the soil; if it feels dry, it's time to water. Adjust the watering frequency based on the soil's dryness to help revive drooping leaves. Ensure proper drainage in the pot to prevent waterlogging, which can lead to drooping and other issues.

Dry Soil

Dry soil is a common issue that can cause ferns to turn brown. To remedy this, rehydrate dry soil by watering thoroughly until you see water draining from the bottom of the pot. Use the finger dip test regularly to accurately gauge soil dryness and prevent overwatering or underwatering. Adjust your watering schedule accordingly to maintain optimal soil moisture levels for healthy fern growth.

Reasons for Browning


Over-watering can lead to brown tips on ferns. To prevent this issue, reduce watering frequency and let the soil dry slightly between waterings. Keep a close eye on your fern's health for any signs of over-watering.


If you notice your ferns turning brown due to under-watering, increase the watering frequency. Ensure that your ferns receive adequate water to avoid dehydration. Look out for wilting or dryness as clear indicators of under-watering.

Low Humidity

Low humidity levels can contribute to browning in ferns. Boost the humidity around your plants by creating a more humid environment for them to thrive. Regularly check your ferns for any distress signals in low humidity conditions.

Nutrient Deficiency

Nutrient deficiencies can also cause browning in ferns. Address any nutrient deficiencies promptly by using a balanced fertilizer to provide essential nutrients to your plants. Keep an eye on your fern's growth patterns for any signs of nutrient deficiency.

Addressing Watering Issues

Correct Frequency

Adjust watering frequency based on fern species and environmental conditions. Follow a consistent schedule to keep ferns healthy. Monitor their response to watering changes for the right frequency.

Proper Techniques

Use appropriate watering techniques to prevent browning in ferns. Avoid over-watering by watering at the plant's base. Prune ferns correctly for healthy growth and to prevent browning.

Managing Light and Humidity

Ideal Light Conditions

Ferns thrive in indirect light settings, promoting healthy growth without browning issues. Avoid direct sunlight exposure to prevent ferns from turning brown. Regularly check how ferns react to light levels for necessary adjustments.

Humidity Solutions

Enhance fern health by introducing humidity solutions such as misting or pebble trays. These methods create a conducive environment for ferns to flourish. Keep a close eye on fern well-being post-application of humidity solutions.

Combatting Pests and Diseases

Common Pests

Spider Mites

  • Check ferns regularly for spider mite infestations to prevent browning.
  • Promptly treat any spider mite issues to avoid further damage.
  • Eliminate spider mites using natural or chemical remedies effectively.


  • Look for mealybug presence on fern leaves and stems during inspections.
  • Treat mealybug infestations promptly to prevent browning of the ferns.
  • Eradicate mealybugs using appropriate methods to protect the plants.

Diseases Treatment

Fungal Infections

  • Keep an eye on ferns for signs of fungal infections like leaf spots.
  • Promptly treat fungal infections to prevent browning and maintain plant health.
  • Adjust watering practices to reduce fungal growth on the ferns effectively.

Bacterial Issues

  • Watch out for bacterial infections in ferns, which may cause yellowing or browning.
  • Treat bacterial problems promptly to prevent further damage to the plants.
  • Use suitable fungicides or bactericides to address bacterial issues effectively.

Reviving Browned Ferns

Pruning Brown Leaves

Trim brown leaves at the base to encourage new growth. Remove dead or browning leaves promptly for fern health. Prune carefully to prevent further damage during trimming.

Adjusting Care Routine

Modify care routine based on fern response to environmental conditions. Monitor fern health closely for necessary adjustments. Implement changes gradually to prevent stress on ferns.

Recovery Signs

Look for signs of recovery in ferns post addressing browning issues. Monitor new growth and leaf color for improvements. Continue proper care practices to support fern recovery.

Preventive Measures and Maintenance

Regular Monitoring

Regularly monitor fern health to catch browning early. Check soil moisture, leaf color, and overall plant condition often. Implement preventive actions based on monitoring results.

Keep an eye on your ferns by checking soil moisture levels frequently. Ensure the soil is damp but not waterlogged to prevent browning. Adjust watering accordingly.
