Identifying and Treating Ginkgo Diseases Identifying and Treating Ginkgo Diseases

There are not many Ginkgo diseases mainly because this tree is quite resistant to diseases, pests and even fire. This is why the tree has been able to withstand through the centuries. It dates as far back as 200 million years.

The Ginkgo tree can grow to be over 100 feet tall and are commonly seen growing in large cities. This tree is one of the hardiest where air pollution is concerned. The unique fan-shaped leaf, with its 2 lobes, makes the Ginkgo tree very easy to recognize.

Resistant to Disease

Ginkgo trees are very resistant to any type of disease or insects. They have lasted for centuries because of this hardiness. If you want to plant a great looking tree in your landscaping, that you will not have to care for on a regular basis, then the Ginkgo tree is for you.

While many other trees will need to be protected from various diseases, pests and insects, the Ginkgo will stand tall. That does not mean there are not some problems that can affect the Ginkgo. Here are some tips to help you identify and treat any potential problems.

Honey Fungus

The Honey fungus is essentially a mushroom that grows on the bark of trees. It is commonly seen on coniferous trees such as the Ginkgo. They will grow in clusters of 3 to 6 different mushroom caps and will begin to feed upon the nutrients in the tree. The Honey fungus is potentially life threatening to the Ginkgo tree and can spread from a dead tree to a live tree very easily.

Initial signs of a Honey fungus infection include the dying back of the leaves or even failure of leaves to show up in the spring. You will also notice black, almost lace like strands to appear on the bark around the tree. Accompanying these signs will be clusters of growths that grow in the autumn.

Treatment of the honey fungus requires that the infected areas be removed from the tree. If it has infected the roots or the trunk, you will need to remove the entire tree. Once the tree is removed, dig a trench around the area and fill with some fungicide.

Slugs

Besides the Honey fungus disease, slugs can be a pest. This only occurs in young seedlings as they are establishing their root system. The slugs will attach the seedlings and eat them. Once the tree is more mature, the thick, waxy leaves are too hard for the slugs to be able to eat through.

Ginkgo Weather Problem

Since the tree has lasted or so long, there are very few diseases and pests that can harm the tree. However, the tree can suffer damage due to weather, cold weather especially. In the cold winter months, if it is a snowy winter, or the fall had a lot of rain, the freezing temperatures can cause cracks in the trunk or the limbs. In the spring time, you can treat these cracks by removing the limbs, or patching with tar.
