Creeping Jenny (Lysimachia nummularia) is a popular groundcover plant that is well-known for its bright green, trailing foliage. It is a low-maintenance plant that is ideal for rock gardens, borders, and water features. However, like all plants, it can suffer from various issues that can affect its health and appearance. One of the most common problems that creeping Jenny plant owners face is brown spots on the leaves.
Reasons for Brown Spots on Creeping Jenny Plants
There are several reasons why your creeping Jenny plant may develop brown spots on the leaves. The following are some of the most common causes:
1. Overwatering
Creeping Jenny plants prefer moist soil, but they don’t like to be overwatered. When you overwater your plant, it can lead to root rot, which in turn can cause brown spots on the leaves. To prevent this issue, make sure you water your plant only when the topsoil feels dry to the touch.
2. Fungal Infection
Fungal infections can also cause brown spots on creeping Jenny leaves. These infections are more common in humid environments and in plants that are overcrowded or have poor air circulation. To avoid this issue, make sure you space out your plants properly and prune them regularly to ensure proper airflow.
3. Sunburn
Creeping Jenny plants prefer partial shade but can tolerate some direct sunlight. However, if your plant is exposed to too much direct sunlight, it can develop brown spots on the leaves due to sunburn. To prevent this issue, make sure you place your plant in an area where it gets partial shade during the hottest hours of the day.
4. Pests
Pests such as spider mites and aphids can also cause brown spots on creeping Jenny leaves. These pests feed on the sap of the plant, which can cause discoloration and damage to the leaves. To prevent this issue, make sure you inspect your plant regularly and treat it with insecticide if necessary.

If your creeping Jenny plant has brown spots on the leaves, there are several things you can do to treat the issue. The following are some of the most effective treatments:
