Why Are My Outdoor Plants Leaves Turning Yellow?

Yellowing leaves on outdoor plants is a common problem and can be caused by a variety of factors. In most cases, yellowing leaves are a sign of an unhealthy plant, and the issue must be addressed to ensure the health of the plant.

The most common causes of yellowing leaves are inadequate sunlight, improper soil pH, over-fertilization, and pests or disease. It is important to identify the cause of the yellow leaves before attempting to treat it.

Inadequate Sunlight

Not enough sunlight can cause yellowing leaves on outdoor plants. Plants require full sun for at least six hours each day in order to thrive. If your plants are not getting enough sunlight, move them to a sunnier location.

Improper Soil pH

The pH of soil can also affect the health of outdoor plants. Soil that is either too acidic or too alkaline can cause yellowing leaves. A soil test should be performed to determine the exact pH level and then steps taken to adjust it accordingly.

Over-Fertilization

Over-fertilization can also lead to yellowing leaves on outdoor plants. Too much fertilizer applied at once can cause a build-up of salts in the soil which will prevent absorption of nutrients by the plant’s roots. Fertilize only when necessary and according to package directions.

Pests and Disease

Pests or disease may also be responsible for yellowing leaves on outdoor plants. Common pests include aphids, mealybugs, whiteflies, spider mites, and scale insects.

Diseases such as root rot or fungal infections may also cause yellowing leaves. Treatments for pests and diseases vary depending on the type present.
