A healthy Monstera (Monstera deliciosa) is the pride of any indoor plant enthusiast, with its iconic split leaves adding a touch of the tropics to your home.
But when those lush leaves start curling, it’s a clear sign something isn’t right.
The good news? This common issue is usually easy to fix once you know the cause.
In this guide, I will explain the reasons for curling Monstera leaves and recommend effective methods for restoring their health and lush appearance.
6 Common Reasons for Monstera Leaf Curling
Monstera leaves curl due to overwatering, underwatering, low humidity, pest infestations, temperature stress, or Fertilizer Problems. Identifying and addressing these causes can restore your plant’s health.
1. Overwatering and Root Rot
One of the most common reasons for monstera curling leaves is overwatering. When the soil stays too wet, the roots can’t get enough oxygen, leading to root rot. Signs include yellowing leaves, mushy soil, and curling tips.
How to Fix It:
- Check the soil moisture. If it’s soggy, stop watering immediately.
- Repot your Monstera with fresh, well-draining soil.
- Water only when the top 1-2 inches of soil feel dry.
2. Underwatering and Dehydration
On the other hand, underwatering can also cause curling. When a Monstera doesn’t get enough water, its leaves curl to reduce water loss.
How to Fix It:
- Feel the soil. If it’s dry and crumbly, it’s time to water.
- Give your Monstera a thorough soak and let the excess water drain.
- Keep a consistent watering schedule.
3. Low Humidity Levels
Tropical houseplants like Monsteras thrive in humidity levels between 60% and 80%. Dry air can stress the plant, causing its leaves to curl.
How to Fix It:
- Use a humidifier near your plant.
- Mist the leaves occasionally or place the pot on a pebble tray filled with water.
- Group plants together to naturally increase humidity.
4. Temperature Stress from SUN Exposure
Monsteras do well in bright, indirect light and like temperatures between 65°F and 85°F. Too much direct sunlight can make their leaves blister, turn yellow, and curl. Extreme heat, cold, or sudden temperature changes can also stress them.
How to Fix It:
- Move the plant to a spot with stable temperatures.
- Avoid placing it near heat vents, AC units, or open doors.
5. Pest Infestations
Pests like spider mites or thrips feed on the plant’s sap, damaging the leaves and causing curling or discoloration.
How to Fix It:
- Inspect your Monstera for tiny bugs or webbing.
- Wipe the leaves with a mixture of water and mild soap.
- Use neem oil or an insecticidal spray to eliminate pests.
6. Fertilizer Problems
Too much or too little fertilizer can affect your Monstera’s health. Excess fertilizer causes salt buildup in the soil, while deficiencies can lead to weak growth.
How to Fix It:
- Flush the soil with water to remove excess salts.
- Use a balanced, water-soluble fertilizer once a month during the growing season.
- Avoid over-fertilizing during the winter when growth slows down.
Preventing Monstera Leaf Curling
Consistent Care
- Water the plant only when the top 2-3 inches of soil are dry.
- Place your Monstera in bright, indirect light.
- Wipe leaves with a damp cloth to remove dust and pests.
