Have you ever heard of sudden oak death wilt? It can be a challenge to tell the difference between the two so we are providing you fascinating and helpful information! Sudden oak death, which is a disease that affects oak trees, spread by a pathogen called Phytophthora Ramorum. This pathogen can affect over 100 other plant species but does not affect them as drastically as it does oak trees. Sudden oak death can occur anywhere in the country but has most commonly been seen on the west coast. It is estimated that over 1 million trees have been killed by this disease in the past 10 years. Some signs that your tree may have this issue are of trunk or bole cankers, bark beetles, and fungi growth. Oak wilt is caused by a fungus called Ceratocystis Fagacearum. This has mainly been seen in the midwest and can affect all oak trees, with the exception of white oaks. Some signs of this are wilting leaves, dull bronze or green color, and leaves appearing water-soaked. Most of the time, but not always, sudden oak death affects the trunk and branches first, while oak wilt tends to affect leaves first.
