Timely action can save your tree from being damaged severely. Call professional tree service for expert care.

Anthracnose

Anthracnose is a fungal disease caused by Colletotrichum and related species. The area’s humid climate and warm temperatures create ideal conditions for fungal spores to spread, especially in spring and fall. It primarily affects sycamores, maples, oaks, and dogwoods.

Signs of Anthracnose:

Dark sunken spots on leaves
Twisted, curled, or deformed foliage
Premature leaf drop in spring
Cankers on twigs and branches
Brown blotches along leaf veins
Slowed tree growth and weak branches

Powdery mildew

Powdery mildew is caused by fungal pathogens like Erysiphe and Oidium. It affects oaks, dogwoods, and crepe myrtles. Athens‘ warm days and cool, humid nights create the perfect conditions for fungal spores growth. You can identify the disease with the following signs:

White powdery coating on leaves
Distorted or curled leaf edges
Yellowing and premature leaf drop
Stunted growth in young shoots
Reduced flowering and fruit production
Weak, stressed tree appearance

Prune infected branches, improve air circulation, and apply fungicidal sprays. You should also overhead watering, and plant resistant tree varieties to prevent future infections.

Oak wilt

Oak wilt is caused by the fungus Bretziella fagacearum, which spreads through root grafts and beetles. The warm, humid climate of the city accelerates fungal growth and insect activity, making oaks more vulnerable. Red oaks decline rapidly, while white oaks may survive longer. Common signs of the disease include:

Wilting and browning from leaf edges
Sudden leaf drop in summer
Dark streaks under the bark surface
Fungal mats with a sweet smell
Dieback starting from the tree crown
Rapid tree death in red oaks

Dutch Elm Disease

Dutch Elm Disease is caused by the fungi Ophiostoma ulmi and Ophiostoma novo-ulmi, spread by elm bark beetles. It primarily affects American elms, especially in spring and summer when beetles are most active. If you notice any of the below signs, its safe to call professionals:

Wilting and yellowing of upper leaves
Brown streaks under the bark
Sudden branch dieback in summer
Premature leaf drop and thinning canopy
Cracked bark with fungal growth underneath
Rapid tree decline within weeks

Prune infected branches, remove dead trees, and inject fungicides for treatment. Prevent beetle infestations by maintaining tree health and avoiding pruning during peak beetle season.

Verticillium wilt

This fungal disease can affect maples, elms, ash, and redbuds during the warm spring and summer months when soil temperatures rise. It is caused by Verticillium dahliae and Verticillium albo-atrum, soilborne fungi that infect tree roots. Infected trees may showcase below signs:

Leaves suddenly wilt and turn yellow or brown in mid-summer.
Branches die back unevenly, often affecting one side first.
Dark streaks appear in the sapwood beneath the bark.
Growth slows, and smaller-than-usual leaves develop on branches.
Trees struggle to recover and decline over multiple seasons.
