By | Updated November 15, 2023

Alocasia plants are typically known for their large, dark green leaves that add a tropical touch to any home.

They are easy to care for, making them a popular choice for indoor and outdoor gardens.

However, alocasia plants can sometimes experience leaf curling. This can be due to several reasons, ranging from pests to improper watering.

Here are 10 solutions to help you solve the mystery of why your alocasia leaves are curling.

Why Are My Alocasia Leaves Curling and How Can You Fix It?

There are several reasons why alocasia leaves may curl.

Here are the most common causes why alocasia leaves curl and how you can fix it:

1. Underwatering

One of the most common reasons for alocasia leaf curling is underwatering.

Alocasias are native to tropical regions and prefer moist soil.

When the plant doesn’t receive enough water, the alocasia leaves will begin to droop and curl in an attempt to conserve moisture.

How To Tell If Your Alocasia Is Underwatered

There are a few telltale signs that your alocasia plant is not getting enough water, including:

  • Leaves that are wilted or drooping
  • Leaves that are dry or brown at the edges
  • Soil that is dry to the touch
  • Stunted growth

How To Fix An Underwatered Alocasia

If you think your alocasia is underwatered, there are a few things you can do to fix the problem.

  • Water your alocasia thoroughly, making sure that the soil is evenly moistened.
  • Water more frequently, making sure to keep the soil moist but not soggy.
  • Increase humidity by misting the leaves or using a humidifier.
  • Remove any dried leaves or dead stems.
  • Ensure that your alocasia has good drainage by using a well-draining potting mix and a pot with drainage holes.

2. Overwatering

While underwatering is a common cause of alocasia leaf curling, overwatering can also be to blame.

Alocasias are sensitive to overwatering and will start to experience leaf curling if they are sitting in water for too long.

How To Tell If Your Alocasia Is Overwatered

There are a few telltale signs that your alocasia is getting too much water, including:

  • Leaves that are yellow or brown
  • Leaves that are wilted or drooping

  • Fertilize your alocasia with a balanced fertilizer that contains nitrogen, phosphorus, and potassium
  • Apply a layer of compost around the base of the plant
  • Water your alocasia regularly to keep the soil moist but not soggy

7. Compacted Soil

Alocasias also prefer loose, well-draining soil and can experience leaf curling if the soil they are planted in is too compacted.

Compacted soil doesn’t allow alocasias to develop a strong root system, which can cause the plant to become stunted in growth and result in wilted or drooping leaves.

How To Tell If The Soil Is Too Compacted

There are a few telltale signs that the soil is too compacted for alocasias, including:

  • Leaves that are wilted or drooping
  • A plant that is overall stunted in growth

  • Loosen the soil around the plant with a garden fork or trowel
  • Mix in some organic matter, such as compost or peat moss
  • Repot the alocasia into a pot with loose, well-draining soil

8. Overfertilization

Alocasias can also experience curled leaves if they are overfertilized.

When alocasias are overfertilized, the roots can’t absorb all of the nutrients, and the excess nutrients build up in the soil.

This can cause alocasia leaves to turn yellow or brown and eventually curl.

How To Tell If Your Alocasia Is Overfertilized

There are a few telltale signs that your alocasia is overfertilized, including:

  • Leaves that are yellow or brown

  • Don’t fertilize your alocasia for a few months to allow the plant to recover
  • Discard any dead or dying leaves

9. Transplant Shock

Alocasias can also experience curling leaves if they are transplanted too often or not appropriately transplanted.

Transplant shock is a common problem for alocasias because they have a shallow root system easily damaged when the plant is moved.

When alocasias experience transplant shock, the leaves can turn yellow or brown and eventually curl.

How To Tell If Your Alocasia Is Experiencing Transplant Shock

There are a few telltale signs that your alocasia is experiencing transplant shock, including:

  • Repot the alocasia into a pot with fresh, clean soil
  • Prune off any dead or dying leaves
  • Give your alocasia time to recover

10. Root Rot

Alocasias can also experience leaf curling if they have root rot.

Root rot is a common problem for alocasia plants because they are native to humid environments and their roots are easily damaged by too much water.

When alocasias have root rot, the leaves can turn yellow or brown and eventually curl.

How To Tell If Your Alocasia Has Root Rot
