What Causes Black Spots on Tree Leaves in Milton, GA?

Property owners value their trees highly and are often concerned when they show signs of distress or disease. One of the common issues clients ask about is black spots on tree leaves. Read on to learn more about the causes of this type of leaf damage and how the experts at Southern Tree Pros, the leading tree service company in Milton, GA, helps clients manage the underlying problems.

Leaf Spots on Trees Are Common

Leaf spots are a common issue among many tree species native to Georgia. Most leaf spots are not evidence of serious problems by themselves. However, they could require attention and treatment when seen in combination with other conditions.

Tree spots usually occur on broadleaf deciduous trees like oaks, chestnuts, maples, and sycamores. They are more prevalent during hot, wet weather or when cool temperatures arrive earlier than expected in the fall.

Typical Causes of Black Leaf Spots

There are several sources of black leaf spots.

Leaf Spot Diseases

Leaf spot disease describes a broad range of conditions that can cause black leaf spotting. Several categories of leaf spot diseases are spread by the spores created by various species of fungus. Spores are like tiny seeds, as they are how fungi reproduce and spread to other host plants.

Spores move from tree to tree in the wind and rain. Insects also spread leaf spot diseases by transferring spores as they travel and feed on growing and fallen leaves. Human activity, such as landscaping maintenance and tree pruning, also transfers spores. A tree expert can identify fungal diseases from the tiny spores inside the black leaf spot.

Bacterial diseases can also cause problems. These form yellow edges around infected parts of leaves. The yellow “halo” encloses the dark spot, which is sometimes brown as well as black.

Deciduous trees that produce new leaves each spring can usually recover from black leaf spots. While individual leaves will not heal from leaf spot diseases, the biological cause of one season’s disease will not necessarily return the following season.

Agricultural Practices

Black leaf spots can result from poor drainage, overwatering, excessive drought, or fertilizer burn. These situations disturb a tree’s normal metabolic process and injure leaves. Poorly draining soil or improper use of soaker hoses can lead to excessive water, resulting in leaf damage.

These types of injuries cause more than just spotting, however. Water or fertilizer problems cause leaves to turn yellow or brown along their edges and at the tips rather than producing black spots on tree leaves

Insect Damage

Sap-sucking insects feed on leaves along with tree branches and often leave spots on leaves. They are usually yellow or white instead of black and are much smaller than the spots caused by leaf spot diseases.
