Different types of street trees are available in many areas throughout the nation. The stately ash tree is used as a street tree in various areas. This tree is prized as the yard tree as its maximum shade in the summer. This tree grows well in the plant hardiness zones range from three to nine specified by the U.S. Department of Agriculture. The species type is one of the main reasons behind its growth level. There is a notable augmentation of the deadly emerald ash borer spreading from the East across the nation.

Many people these days think about the main reasons behind the ash tree leaves falling off in winter and other seasons.

Some ash trees are being planted as street trees. National parks in the nation have various ash trees. The U.S. Forest Service removes some ashes in national parks for various reasons.

Though the bright green ash bradawl infestations cause leaves of these trees fade and defoliation, these trees develop black areas on leaves and suffer from anthracnose. However, these trees are not likely to suffer from an emerald ash borer infestation.

Leaf spot otherwise known as leaf blight or Anthracnose is one of the ash tree leaf diseases. This disease is caused by different fungi.

There are different symptoms for this problem. However, the main symptoms are dead and irregular areas on leaves. The fungus in the ash tree spreads by water in rain droplet form. This is because standing water after overhead watering, irrigation and heavy rainfall.

Winter for a long time is one of the main reasons behind ever-increasing amount of leaves fall off from the ash tree. Once the weather becomes warm, the heat from the Sun slows down the overall progress of the disease. However, this positive change does not cure the disease. Black, brown or tan spots develop and spread when the disease progresses in the ash tree. Anthracnose does not kill any mature ash tree. Regular infections in this tree lead to decline and eventually die.

Listeners to the main causes of ash tree losing leaves these days make an informed decision about how to increase the healthy growth of ash trees. Leaves of ash tree suffer from acute anthracnose infection may get dead tissue in large areas of leaves. This negative change increases the overall possibilities of leaves fall and the entire ash tree become defoliated over time.  Though new leaves appear subsequent to the infected leaves fall, these leaves are not healthy.
