But did you know curling leaves could indicate a problem lurking beneath the verdant foliage? 

In this blog post, we’ll explore various causes behind peperomia leaves curling – from improper watering habits to nutrient deficiencies – and provide solutions to restore your beloved green friend’s health.

Causes Of Peperomia Leaves Curling

There are various reasons why the leaves of Peperomia plants may curl. 

These include problems with watering, lighting, temperature and humidity, root rot, pest attacks, excessive fertilization, and lack of nutrients.

Improper Watering

One of the leading causes of peperomia leaf curling is improper watering. 

This resilient houseplant can tolerate both overwatering and underwatering to some extent, but when pushed beyond its limits, the plant’s health will decline, leading to curled leaves.

Underwatered peperomias tend to exhibit a wilted appearance accompanied by leaf curling as they try to conserve water by reducing the surface area exposed for transpiration.

To maintain a healthy balance in your peperomia’s hydration needs, check the moisture level of its potting soil before each watering session. 

Use your finger or a moisture meter to gauge if it’s time for another drink; ideally, only water when about 50% of the potting mix has dried.

When you proceed with watering your peperomia plant, use ample amounts so that excess water drains from the bottom of the container — this helps emulate natural rainfall while preventing roots from being submerged in standing water.

Lighting Issues

Lighting is crucial to your peperomia plant’s overall health and well-being. 

These tropical plants thrive in bright, indirect sunlight, making lighting issues one of the common causes of leaves curling.

Insufficient light exposure can cause the foliage to struggle with photosynthesis, leading to weaker cell walls and curled leaves.

To provide optimal lighting conditions for your peperomia, place it near an east or west-facing window where it will receive consistent filtered sunlight. 

If natural light is limited in your home environment, consider supplementing with artificial grow lights designed for indoor plants.

Temperature And Humidity Stress

Temperature and humidity stress are significant factors that can lead to curling leaves in peperomia plants. 

These tropical houseplants thrive best in temperatures ranging from 65 to 80 degrees Fahrenheit, with a humidity level of around 40-50%.

To maintain appropriate temperature and humidity levels for your peperomia, place it away from drafty windows or direct heat sources like radiators or air conditioning vents.

If necessary, utilize a humidifier nearby to bolster moisture levels in dry indoor spaces. 

Additionally, placing the potted plant on a tray filled with water and pebbles can help create a microclimate with increased ambient humidity surrounding the plant.

Root Rot

Root rot is a common problem among peperomia plants that can cause their leaves to curl. 

This condition usually occurs when the soil around the plant becomes waterlogged and lacks proper drainage, leading to an overgrowth of harmful fungi and bacteria in the root system.

A clear sign of root rot is a foul odor emanating from the potting mix or black spots on the roots themselves. 

To treat this issue, carefully excavate your plant, removing all affected roots with sharp scissors or pruning shears before repotting it in fresh potting soil that drains well.

Applying a rooting hormone can stimulate new growth and help restore your plant’s health.

Pest Infestations

One of the common causes of peperomia leaf curling is pest infestation. Mealybugs, mites, fungus gnats, and shore flies are some pests that can infect peperomia plants.

These tiny bugs can damage the plant by feeding on its leaves or sucking out its sap, resulting in curled leaves.

To avoid pest infestations, practice proper plant care, such as watering your plant correctly and providing adequate lighting conditions. 

Regularly monitor your plant for any signs of a pest infection and take quick action to treat it before it spreads.


Overfertilization is one of the causes of peperomia leaves curling. 

This happens when too much fertilizer is applied to the soil, leading to a buildup of salts that can harm the plant’s roots and cause dehydration.

Signs of overfertilization include brown tips on the leaves or black spots on the foliage

Following proper fertilizing guidelines and using a balanced liquid fertilizer formulated for houseplants is important to prevent this issue.

It’s also recommended to flush out excess salts occasionally by watering with plain water until it runs through the drainage holes in the pot.

Nutrient Deficiencies

Peperomia plants require a balanced supply of macronutrients and micronutrients to grow and maintain healthy foliage. 

A common cause of Peperomia leaves curling is nutrient deficiency, particularly calcium deficiency.

Calcium is essential for sturdy stems and healthy cell walls in the plant’s foliage. 

Young leaves may curl downwards without an adequate supply of calcium, while older leaves remain unaffected.

To prevent nutrient deficiencies in your Peperomia plants, ensure they receive sufficient moisture, light, and temperature levels for optimal growth. 

It is important to fertilize regularly with a balanced liquid fertilizer that contains all the necessary nutrients the plant requires.
