Geraniums are beautiful and easy-to-care-for plants that can be enjoyed both indoors and outdoors. However, like any plant, geraniums can develop problems, including brown spots on the leaves. If you notice brown spots on your geranium plant, it’s important to understand the causes and how to treat them.
Causes of Brown Spots on Geranium Leaves
There are a few different reasons why your geranium plant may develop brown spots on its leaves:
1. Overwatering or Underwatering
Geraniums thrive in well-draining soil that is kept moist but not waterlogged. If your geranium is overwatered or underwatered, it can stress the plant and cause brown spots on the leaves. Overwatering can also lead to root rot, which is a more serious problem that can kill the plant.
2. Fungal or Bacterial Infections
Fungal or bacterial infections can also cause brown spots on geranium leaves. These infections can be caused by poor air circulation, high humidity levels, or watering the foliage instead of the soil. Some common fungal infections that affect geraniums include botrytis blight and powdery mildew.
3. Pests
Pests such as spider mites, thrips, and aphids can also cause brown spots on geranium leaves. These pests feed on the sap of the plant, which can cause discoloration and damage to the leaves.
How to Treat Brown Spots on Geranium Leaves
The treatment for brown spots on geranium leaves depends on the underlying cause:
1. Adjust Watering Habits
If your geranium is overwatered or underwatered, adjust your watering habits accordingly. Make sure the soil is moist but not waterlogged, and avoid watering the foliage.
2. Remove Infected Leaves
If your geranium has a fungal or bacterial infection, remove the infected leaves and dispose of them in the trash. This will help prevent the infection from spreading to other parts of the plant. You can also use a fungicide or bactericide to treat the plant.
3. Use Pesticides
If your geranium has a pest infestation, use an insecticidal soap or neem oil to treat the plant. Make sure to follow the instructions on the label carefully, and avoid using pesticides that are toxic to bees and other beneficial insects.

No, geraniums are not edible plants and should not be consumed. If you have any concerns about the safety of your plants, consult a medical professional or poison control center.
In conclusion, brown spots on geranium leaves can be caused by overwatering, underwatering, fungal or bacterial infections, or pest infestations.
