Elephant ear plants (also known as colocasia) are a popular and easy-to-care-for houseplant. They are known for their large foliage and tropical appearance. While they can be grown outdoors in warm climates, they are most often grown as houseplants. With proper care, elephant ear plants can thrive indoors for many years. Heres how to help yours thrive:
Has your gorgeous elephant ear plant suddenly started developing white patches on its leaves? Don’t panic! At Stone Post Gardens, we’ve helped countless gardeners deal with this common issue. I’ll walk you through everything you need to know about why those majestic leaves are losing their color and how to fix it.
What’s Causing Those White Leaves?
After working with hundreds of elephant ear plants (Colocasia esculenta), I’ve found these are the main culprits behind white leaves:
1. Sunburn – The #1 Culprit
The most common reason your elephant ear leaves are turning white is good old-fashioned sunburn. These tropical beauties love bright light but can’t handle intense direct sun. Signs of sun damage include:
- Pale yellow or white patches on leaves
- Bleached areas that eventually turn brown
- Leaves that look washed out or faded
Quick Fix: Move your plant to a spot with bright indirect light or filtered shade. Morning sun is OK, but protect it from harsh afternoon rays.
2. Cold Damage
Being tropical plants elephant ears get super cranky when temps drop below 60°F. Cold damage shows up as
- White, water-soaked spots
- Shriveled, curling leaves
- Tissue that turns brown or black
Quick Fix: Keep your plant cozy! Move it indoors before temps drop too low and maintain temps above 60°F.
3. Nutrient Problems
Your elephant ear might be trying to tell you it’s hungry! Nutrient deficiencies cause
- White veins with pale green leaves (nitrogen deficiency)
- Yellow tissue between green veins (iron/magnesium issues)
- Overall pale, lackluster growth
Quick Fix Feed monthly with balanced liquid fertilizer during growing season, We’ve had great results mixing in some compost too!
4. Root Rot
Sometimes the problem starts underground. Overwatering leads to root rot, which shows up as:
- Pale yellow or white leaves
- Wilting despite wet soil
- Mushy, stinky roots
- Generally unhappy plant
Quick Fix:
- Check roots for mushiness
- Trim away rotted parts
- Repot in fresh, well-draining soil
- Adjust watering schedule
How to Prevent White Leaves
Here’s what I do to keep our elephant ears looking their best:
Light & Location
- Choose spots with morning sun/afternoon shade
- Use shade cloth if needed
- Avoid hot afternoon sun exposure
- Provide filtered light under trees
Water & Soil
- Let top inch of soil dry between waterings
- Use well-draining potting mix
- Add perlite or sand for better drainage
- Never let plants sit in standing water
Temperature & Humidity
- Keep above 60°F always
- Bring plants in before frost
- Group plants to increase humidity
- Use pebble trays for extra moisture
Feeding Schedule
- Monthly fertilizer during growing season
- Use balanced liquid fertilizer
- Add compost for slow-release nutrients
- Don’t feed during winter dormancy

If your elephant ear is already showing white patches, here’s your action plan:
-
Assess the Damage

Final Thoughts
White leaves on elephant ears usually signal environmental stress rather than serious disease. With proper care adjustments, most plants bounce back just fine. At Stone Post Gardens, we’ve seen even severely bleached plants recover with patience and proper care.
Remember, every plant parent makes mistakes – what matters is learning and adjusting! Keep an eye on your elephant ear, make changes as needed, and don’t be afraid to ask for help if you’re stuck.

Elephant ear plants prefer warm temperatures between 18-29°C. They also need high humidity, so its a good idea to mist the leaves once or twice a week. You can also place a humidifier near the plant to increase the humidity or keep them in a naturally humid place like a bright kitchen or bathroom.
Should I fertilise my elephant ear plant?
Feed your elephant ear plant with a balanced liquid fertiliser every two weeks during the growing season (spring and summer) to encourage new growth. You dont need to worry about fertilising during the winter months.
