Cleome plants are known for their delicate, beautiful flowers that bloom in a variety of colors. However, sometimes these plants can develop brown spots on their leaves and flowers. If you are experiencing this issue with your Cleome plant, don’t worry – there are several reasons why this might be happening and several solutions to remedy the situation.

Possible Causes of Brown Spots on Cleome Plants

Fungal Diseases

One of the most common causes of brown spots on Cleome plants is fungal diseases. These diseases can be caused by a variety of factors, including poor air circulation, overwatering, and high humidity levels. Some common fungal diseases that can affect Cleome plants include powdery mildew and leaf spot.

Powdery mildew is a fungal disease that causes a white or grayish powder to appear on the leaves of plants. This powder can eventually turn brown and cause the leaves to wilt and die. Leaf spot, on the other hand, causes brown spots to appear on the leaves of plants. These spots can vary in size and shape and may eventually cause the leaves to fall off.

Pests

Another possible cause of brown spots on Cleome plants is pests. Some common pests that can affect these plants include spider mites, aphids, and thrips. These pests can cause damage to the leaves and flowers of Cleome plants, which can lead to brown spots.

Spider mites are small insects that feed on the sap of plants. They are often found on the undersides of leaves and can cause yellowing or browning of the leaves. Aphids are another common pest that feeds on the sap of plants. They can cause distortion or curling of the leaves, as well as the appearance of brown spots. Thrips are tiny insects that feed on the flowers and leaves of plants. They can cause discoloration and distortion of the leaves and flowers, which can lead to the appearance of brown spots.

Environmental Factors

Finally, brown spots on Cleome plants can also be caused by environmental factors. These factors can include exposure to extreme temperatures, drought, or exposure to chemicals such as herbicides or pesticides.
