Leyland cypress trees are known for their fast growing nature and the privacy screen they provide. They are very hardy and tolerant to drought, however they are not susceptible to pests or diseases. A very common disease that has been affecting many leyland cypress trees in the area is called Seiridium and Botryosphaeria canker.
What is Seiridium and Botryosphaeria canker?
Much like a common virus, this disease is quickly spread and needs to be stopped at the first sight. These diseases are both a type of fungi that affect the tree during drought or stress and eventually cause dieback on the limbs that spread to the entire tree. The very first symptoms are the yellowing off the foliage on the tree. Dark cracked areas on the bark will start to appear with small cankers as the virus progresses. Seiridium cankers will develop as small black dots and will have oozing substance similar to the resin flow found on healthy leyland cypress trees in Lilburn, Ga. Botryosphaeria cankers often appear just under the bark on the main stem but produce little to no resin.
