African milk plants, also known as Euphorbia trigona, are a popular choice for indoor houseplants. They are native to Africa and have long, succulent stems that can grow up to six feet tall. The plant is easy to care for, making it an excellent choice for beginners. However, one common problem that many African milk plant owners encounter is curling leaves. In this article, we will explore the reasons why your African milk plant leaves may be curling and how to fix the issue.

What Causes Curling Leaves?

There are several reasons why African milk plant leaves may curl. These include:

1. Lack of Water

African milk plants require regular watering to stay healthy. If you neglect them, the leaves will start to curl and wilt. Make sure you water your plant every two weeks or when the top inch of soil feels dry. Avoid over-watering as this can lead to root rot.

2. Overexposure to Sunlight

African milk plants are sensitive to direct sunlight. If your plant is exposed to too much sunlight, the leaves may curl and turn brown. To prevent this, place your plant in a bright spot that receives indirect sunlight.

3. High Temperature

African milk plants thrive in temperatures between 60-85°F (15-29°C). If the temperature in your home is too high, the leaves may curl and turn yellow. Ensure that your plant is kept away from heat sources such as radiators or direct sunlight.

4. Low Humidity

African milk plants prefer high humidity levels of around 50-60%. If the air in your home is too dry, the leaves may curl and turn brown. To increase humidity levels, you can place a humidifier near your plant or mist it regularly.

5. Pests

Pests such as spider mites or mealybugs can also cause leaf curling in African milk plants. If you notice tiny webs or white cotton-like substance on your plant’s leaves, it could be a sign of an infestation. Use insecticidal soap or neem oil to get rid of pests.

How to Fix Curling Leaves

If you notice that your African milk plant’s leaves are curling, here are some steps you can take to fix the issue:

1. Water Your Plant

If your plant’s leaves are curling due to lack of water, give it a good soak. Ensure that the soil is completely saturated and then allow it to drain out excess water.

2. Move Your Plant

If your plant is exposed to too much sunlight or heat, move it to a cooler spot with indirect sunlight.

3. Increase Humidity Levels

If low humidity is causing leaf curling, increase humidity levels by placing a humidifier near your plant or misting it regularly.

4. Treat Pests

If pests are causing leaf curling, treat them with insecticidal soap or neem oil.
