What Causes Geranium Plant Leaves to Curl?

Geraniums are popular plants for gardens and indoor spaces due to their beautiful blooms and easy-to-care-for nature. However, many gardeners may encounter an issue with their geraniums where the leaves start to curl. This can be a frustrating experience for those who have put in time and effort into growing these plants. In this article, we will discuss the reasons behind geranium plant leaves curling and how to fix this issue.

Overwatering

One of the most common reasons for geranium plant leaves to curl is overwatering. Geraniums thrive in well-drained soil that allows excess water to flow through easily. When the soil is too wet, it can lead to root rot which causes leaves to curl and turn yellow. To avoid overwatering your geraniums, make sure you allow the soil to dry out between watering sessions. Also, ensure that the pot or container you are using has proper drainage holes.

Underwatering

On the other hand, underwatering can also cause geranium plant leaves to curl. When the plant does not receive enough water, it tries to conserve it by curling its leaves. To fix this issue, make sure you water your geraniums regularly and deeply so that the water reaches the roots.

Lack of sunlight

Geraniums require plenty of sunlight to thrive. When they do not receive enough light, their leaves can become weak and start to curl. Make sure you place your geraniums in a location where they receive at least 6 hours of direct sunlight each day.

Pests

Pests such as spider mites and aphids can also cause geranium plant leaves to curl. These pests suck out the sap from the leaves, causing them to become distorted and curl up. To get rid of these pests, you can use insecticidal soap or neem oil. Also, make sure you keep your plants clean by wiping the leaves with a damp cloth to prevent infestations.

Temperature

Geraniums prefer moderate temperatures and do not tolerate extreme heat or cold. When exposed to high temperatures, their leaves can curl up as a way of conserving moisture. Make sure you place your geraniums in a location where they are protected from extreme temperatures.

Nutrient deficiency

Geraniums require specific nutrients to grow well. A lack of nutrients such as nitrogen, phosphorus, and potassium can lead to curled leaves. Make sure you fertilize your geraniums regularly with a balanced fertilizer to provide them with the necessary nutrients.

Disease

Diseases such as fusarium wilt and bacterial leaf spot can also cause geranium plant leaves to curl. These diseases are often caused by overwatering or poor soil drainage. To prevent these diseases, make sure you use well-drained soil and avoid overwatering your plants.

In conclusion, there are several reasons why geranium plant leaves may curl. By identifying the cause of this issue, you can take the necessary steps to fix it and ensure that your plants thrive.
