Why Are My Philodendron's Leaves Curling?
Philodendrons are gorgeous accent plants, with playful heart-shaped, often variegated foliage and tendril-like vines that blend into any space. They're wonderfully easy-care, but when they're less than happy they can show it through curling leaves. Here's why your Philodendron's leaves are curling and what you can do about it.
At Léon & George, our master gardeners have spent nearly a decade growing premium plants and helping thousands of plant parents nationwide, so the guidance here comes straight from hands-on experience.
Underwatering
Underwatering is the number-one cause of curling and dryness in Philodendron foliage. Water your plant whenever its topsoil is dry, checking by lifting a bit of the decorative moss and sticking your finger two inches into the soil. If the top two inches are dry, it's time to water. The soil usually dries out every seven to ten days, but this varies by season, so always check manually rather than watering on a fixed schedule.
Low Humidity
Philodendrons appreciate humidity, especially during the driest months. If you notice curling, mist the plant up to three times a week, using a mister or watering can with a misting attachment. Be mindful of placement too, as air conditioners and heaters dry out the air and can worsen curling.
Light and Recovery
While underwatering and dryness are the usual culprits, too much direct sun can also cause curling as the leaves try to protect themselves. Philodendrons prefer bright, indirect light. Once you've corrected watering, humidity, and light, new leaves will unfurl flat and healthy, and you can trim any badly curled or crispy leaves to tidy the plant.
Frequently Asked Questions
Why are my Philodendron leaves curling?
Curling is most often caused by underwatering or dry air. Water when the top two inches of soil are dry, raise the humidity, and keep the plant out of harsh direct sun.
How often should I water a Philodendron?
Water when the top two inches of soil are dry, typically every seven to ten days depending on the season. Always check the soil manually rather than following a set schedule.
Do Philodendrons like to be misted?
Yes, Philodendrons appreciate extra humidity, especially in dry months. Misting a few times a week, or using a pebble tray or humidifier, helps prevent curling and crisping.
Will curled Philodendron leaves uncurl?
Mildly curled leaves often relax once the plant is properly watered and humidified. Severely curled or crispy leaves won't recover, so trim them and focus on healthy new growth.
