These incredible houseplants are usually low maintenance, but sometimes their leaves start to curl, indicating that something is off. In this article, we will explore the main causes of curling leaves on an Elephant Ear Plant and provide solutions to treat and prevent the issue.
Overwatering is a common cause of curling leaves
If the roots of your Elephant Ear Plant are suffering in waterlogged soil, it can lead to curling leaves. While they dislike dry soil, they hate soggy soil even more. To confirm overwatering as the cause, check the moisture level in the soil.
Carefully unpot your plant and inspect the roots. If they are mushy and dark, they have started to rot. Remove the rotted roots using sharp scissors and eliminate any waterlogged soil. To prevent future issues, adjust your watering routine, especially during winter.
Underwatering can also cause curling leaves
On the other hand, if the soil is bone dry and the roots have started to crisp up, underwatering is likely the culprit. To remedy this, soak your Elephant Ear Plant for 15 to 20 minutes, allowing it to absorb as much water as needed. Let it drip dry before returning it to its pot. Alternatively, gradually water your plant a little bit every day.
Low humidity levels can also be to blame
Elephant Ear Plants thrive in humid environments, making them susceptible to curling leaves in dry air conditions. To confirm low humidity as the cause, use a humidity monitor. Misting the plant, using a pebble tray, or showering it can increase humidity. Another option is investing in a humidifier for a consistent humidity level.
Curling leaves can indicate temperature issues
Elephant Ear Plants prefer temperatures between 60-85°F (16-29°C), resembling their native habitat. Extreme cold or hot air can shock the plant and cause leaf curling. Use a digital thermometer to monitor temperature fluctuations and ensure the plant is not exposed to heating vents, radiators, air conditioning units, or cookers.
Pests can also cause curling
Although pests are less common, they can cause significant damage to your plant. Inspect your Elephant Ear Plant for signs of pests, such as holes in the leaves, white webbing, or visible pests in the potting mix. Shower the plant using slightly higher water pressure and treat with neem oil or insecticide.
Watch out for overfertilization
Overfertilization can lead to a wide range of symptoms, including curling leaves. Excessive nutrient salts can toxify the soil and damage the roots. Remove any fertilizer spikes or replace the soil if using pellets or water-soluble fertilizer. Avoid fertilizing for at least a year to allow the plant to recover.
These are the most common factors that can cause curling leaves in Elephant Ear Plants. It’s essential to diagnose and make changes as soon as possible to revive your plant effectively. For more information on caring for your Elephant Ear Plant, check out our care guide.
