Discover why your indoor palm is turning brown! Anna Scott shares 7 common causes—from tap water crimes to sneaky pests—and how to revive your plant.
My first indoor palm, a majestic Majesty Palm named “Kevin,” started turning brown within weeks. I panicked, overwatered him, then underwatered him… and nearly turned him into a crispy houseplant skeleton. Turns out, palms are drama queens with specific needs.
Here’s why your palm’s leaves are browning—and exactly how to fix it without the guesswork.
1. Tap Water Tantrums 💧
Symptoms: Brown leaf tips, crispy edges.
Why it happens: Chlorine, fluoride, or salts in tap water burn sensitive roots.
Fix:
- Use distilled, rainwater, or filtered water.
- Let tap water sit overnight to evaporate chemicals.
- UK friends: Softened water is a no-go—it’s too salty!
2. Humidity Heist 🌵
Symptoms: Brown edges, curling leaves.
Why it happens: Palms crave tropical humidity (50%+). Dry air = stress.
Fix:
- Mist leaves daily (but avoid soggy fronds).
- Place a humidifier nearby or set the pot on a pebble tray with water.
- Group plants together to create a mini jungle.
3. Overwatering Overkill 💦
Symptoms: Yellowing leaves turning brown, mushy stems, foul soil smell.
Why it happens: Soggy roots suffocate and rot.
Fix:
- Let soil dry 2 inches deep between waterings.
- Repot in well-draining mix (add perlite or orchid bark).
- Snip off dead roots with sterilized scissors.
4. Thirsty Palms 🏜️
Symptoms: Dry, brittle leaves, soil pulling away from the pot.
Why it happens: Underwatering stresses roots, especially in terracotta pots.
Fix:
- Soak the pot in a tray of water for 30 minutes.
- Water deeply until it drains out the bottom—no shallow sips!
5. Sunburn Sabotage ☀️
Symptoms: Brown patches on leaves, bleached color.
Why it happens: Direct sunlight scorches delicate fronds.
Fix:
- Move to bright, indirect light (east-facing windows are ideal).
- Sheer curtains filter harsh rays.
- Exception: Ponytail Palms handle more sun.
6. Sneaky Pest Attacks 🕷️
Symptoms: Speckled brown spots, webbing (spider mites), or sticky residue (scale).
Why it happens: Pests suck sap, leaving damaged tissue.
Fix:
- Wipe leaves with neem oil or insecticidal soap.
- Quarantine the plant to protect others.
- Repeat treatment every 5-7 days.
7. Hunger Games 🌿
Symptoms: Overall yellowing with brown tips.
Why it happens: Nutrient deficiency (usually nitrogen or magnesium).
Fix:
- Feed with a balanced liquid fertilizer at half strength every 6 weeks in spring/summer.
- For quick magnesium fixes, add Epsom salts (1 tsp per gallon of water).
The “Don’t Panic” Brown Leaf Protocol
- Trim carefully: Cut brown tips with clean scissors, following the leaf’s natural shape.
- Check roots: Mushy, black roots? Time to repot!
- Be patient: New growth = success. Old leaves won’t recover.
My Kevin the Palm Comeback Story
After nearly killing Kevin, I:
- Switched to filtered water.
- Bought a $20 humidifier.
- Moved him 3 feet away from the window.
Now he’s sprouting 4 new fronds!

P.S. If you’re in the UK, try a Kentia Palm—it’s less fussy about central heating! 🌴
