Cure krack willow trunk fungus

Asked October 21, 2019, 10:19 AM EDT

How can I fix a krack Willow trunk fungus infection?

The infection started with white mushrooms growing in the grass next to the tree in the spring and through the summer. Within the last two months the fungus started on the trunk and spread up the branches quickly; to about 25 feet on one branch. That branch has no leaves now. Other branches have the fungus but still have leaves.

This looks like one of the common rots that affects trees, perhaps Armillaria rot. Rots can cause a tree to eventually break and fall so, please consult a certified arborist, who will determine if the tree is safe or should be removed. Once rot is in a tree trunk there is no treatment or cure.

A certified arborist is a professional who has taken training in care, diseases, pests and passed certification tests. He/she will come on site and give a complete diagnosis and a plant care plan. Find certified arborists by zip code here—-

In the meantime, stay clear of this tree during severe weather for safety’s sake, until an on site evaluation has been done by a certified arborist.
