Monstera plants are rightly prized for their large evergreen leaves. Some Monstera varieties even have striking fenestrated leaves. So it can be disappointing if your Monstera plant’s leaves start curling. In this article, we’ll explain why your Monstera plant’s leaves are curling and how to fix them.


Why Are My Monstera Leaves Curling?

Why Are My Monstera Leaves Curling?

Underwatering

One of the most common causes of curling Monstera leaves is underwatering. The leaves may start curling inwards if your Monstera doesn’t get enough water. Other symptoms include dry or hydrophobic soil that pulls away from the edge of the pot.

To remedy the problem, water your Monstera plant more frequently. Water your Monstera whenever the top 2 inches of soil feel dry.

If the soil is hydrophobic, soak your Monstera in a tray of water for approximately half an hour. Allow the plant to absorb as much water as possible to rehydrate the soil.

Low Humidity

Monstera leaves can also start curling if the ambient humidity is too low. These plants need warm, humid conditions that replicate the tropical rainforests of Central and South America. They also require humidity levels between 60 and 80%.

Increase humidity around your Monstera plant using humidifiers or pebble trays. You can also mist the plant regularly, but this won’t raise humidity enough on its own. Keep your Monstera away from cold or dry drafts that can dry out the air around your plant.

Too Much Sunlight

Too Much Sunlight

Too much bright, direct sunlight can also cause curling Monstera leaves. Monstera plants need plenty of bright, indirect light to thrive. However, their leaves can become curled and scorched when exposed to intense direct sunlight, especially during the afternoons.

If your Monstera is too close to a window that provides direct sunlight, move it approximately 3 to 5 feet away. East, southeast, or south-facing windows are the best locations for Monstera plants. Alternatively, you can filter direct sunlight using blinds or net curtains.

Incorrect Temperatures

Monstera plants need warm, stable temperatures between 68 and 86ºF (20 to 30ºC) throughout the year. Sudden temperature changes caused by cold or dry drafts can shock Monstera plants.

Curling leaves are a common response to temperature fluctuations. Other symptoms of temperature stress include drooping or yellowing leaves.

Use a thermometer to measure the ambient temperature around your Monstera plant. Move the plant to a more suitable location if the temperature is too cold or too hot.

Diseases or Pests

Diseases or pest infestations can also cause Monstera leaves to curl. Common pests include mealybugs, scale insects, and spider mites. Common Monstera diseases include bacterial leaf spot and root rot.

Many pests will suck the sap from your Monstera plant’s leaves, causing curling or drooping foliage. Eliminate pests using horticultural oils or insecticidal soap. Use neem oil or fungicides to combat diseases.

Wrapping Up

Monstera plants can suffer from curling leaves due to underwatering, low humidity levels, or too much direct sunlight. Incorrect temperatures or diseases and pests may also be responsible.
