Why Are Your Bay Laurel Plant Leaves Curling

Bay laurels are a popular plant species that are grown for both ornamental and culinary purposes. They are easy to grow and care for, but sometimes they may develop problems such as curling leaves. Curling leaves can be caused by several factors, including environmental conditions and pests. In this article, we will discuss the possible reasons why your bay laurel plant leaves are curling and what you can do to fix the problem.

Environmental Factors

Temperature

One of the most common reasons why bay laurel plant leaves curl is temperature stress. Bay laurels prefer temperatures between 60°F and 75°F (15°C to 24°C). If the temperature is too hot or too cold, the plant may experience stress and its leaves may curl.

Humidity

Bay laurels also prefer humid conditions, with a relative humidity level of around 50%. If the air in your home is too dry, it can cause the leaves to curl. You can increase the humidity levels by placing a tray of water near the plant or by using a humidifier.

Watering

Overwatering or underwatering can also cause bay laurel plant leaves to curl. If the soil is too wet, it can lead to root rot, which can cause the leaves to curl and turn yellow. On the other hand, if the soil is too dry, it can cause the leaves to curl up in an attempt to conserve water.

Pests

Bay laurel plants can also be affected by pests that can cause the leaves to curl. Here are some common pests that may be causing your bay laurel plant leaves to curl:

Spider Mites

Spider mites are tiny pests that feed on the sap of bay laurel plants. They are difficult to see with the naked eye but you may notice tiny webs on the leaves. Spider mites can cause the leaves to curl, turn yellow or brown, and eventually fall off.

Scale Insects

Scale insects are another common pest that can infest bay laurel plants. They attach themselves to the stems and leaves of the plant and feed on its sap. Scale insects can cause the leaves to curl and turn yellow or brown.

Aphids

Aphids are small insects that feed on the sap of bay laurel plants. They can cause the leaves to curl and turn yellow or brown. You may also notice sticky honeydew on the leaves or black sooty mold.

How To Fix Curling Bay Laurel Plant Leaves

Now that you know some of the possible causes of curling bay laurel plant leaves, here’s what you can do to fix the problem:

Temperature

If temperature stress is causing your bay laurel plant leaves to curl, try moving it to a location with more suitable temperatures. Avoid placing it near heating vents or air conditioning units.

Humidity

If dry air is causing your bay laurel plant leaves to curl, increase humidity levels by placing a tray of water near it or using a humidifier.

Watering

Make sure you are watering your bay laurel plant correctly. It’s important not to overwater or underwater it. Check the soil regularly and only water when it’s dry about an inch down. Make sure there is proper drainage in the pot so that excess water can escape.

Pests

If pests are causing your bay laurel plant leaves to curl, you may need to treat it with an insecticide or use natural remedies such as neem oil or insecticidal soap. Be sure to follow instructions carefully when using any type of pesticide.
