Sesmas Tree Service professionals can also help you determine an appropriate time to schedule a tree removal or treatment application. Below are the common signs of tree diseases.

Leaf Rust Disease

An orange, reddish or gold spots rupturing leaf surface is a clear sign that you are dealing with a leaf rust disease. Although this may rarely kill a tree, the rust fungus makes the leaves unattractive and weakens the plant by hampering its ability to photosynthesize.

The Fire Blight Diseases

When your tree or shrub branch appears as if it has been scorched by fire, here you'll find the leaves and twigs of your tree suddenly wilt and turn brown or black. The fire blight is a bacterial disease, and it's often spread by infected pruning tools.

The Leaf Spot Diseases

One of the ways of identifying a leaf spot is the discoloration of the foliage, more like a red spot that rots hole in the foliage. This can spread rapidly especially when new foliage is developing.

Powdery Mildew

You will observe the presence of powdery mildew on the leaf surface on dry, cloudy weather with high humidity. The leaves get distorted and this in turn cause stunted plant growth. You'll find this kind of plant diseases mostly on those growing in shaded areas.

The Gall

A plant with the gall disease can be identified with abnormal leaf growth and swollen branches and tree trunk.

The Needle Blight

A common indication that your tree is infested with the needle blight disease is premature defoliation in a mature tree and severe stunt growth of the plant.

Witches Broom

This is characterized by an uncommon and intense growth where shoots infected grow out of lateral buds on the branches of the tree in the form of broom pattern.

 Canker

When a plant appears in the form of frost cracks resulting in a localized dead area on tree trunk or branches, is a clear sign of the canker disease. This allows the inner bark to develop rapidly and slough off exposing the blackened, sooty inner bark.

The Bagworm

When a tree or a shrub is infested with the bagworm, the leaves and the shrubs are eaten up.

Armillaria Root Rot

One of the most visible indicators of an Armillaria root rot are clusters of mushrooms around the tree base. You may also observe that most branches of the tree begin to die as well as excessive wilting.

When working with mature trees, it is recommended that you call a professional arborist with the knowledge needed to heal and remove them effectively. If you notice any of the above-mentioned signs call Sesmas Tree Service for quick treat or removal to avoid any accidental circumstances.
