sick walnut

Asked May 25, 2014, 12:08 PM EDT

We had our property rented for a year and when we returned we noticed our black walnut is ailing. There are many dead branches and other branches are dead at the extremities. I fear thousand canker disease. Should I give up hope of it recovering and have it cut?

Hello,

Below is a link to some information about Thousand Cankers. If the symptoms of your tree match the symptoms in these publications, I suggest you contact a certified arborist for confirmation.
