    Hello folks,

    Can anyone tell me if this Verticillium Wilt? =(
    I'm afraid that it is and that I'm going to lose my beautiful tree!

    I must say, that doesn't look very good. You may get some more learned responses if you are able to take a few more close up pictures of the branches and in particular a branch cut in cross section. Please take advice from those with more knowledge than myself, but the best bet may end up cutting back any diseased branch until you get to a healthy section.

    Thank you for responding. From what I've gathered so far on the forum here and others that if it is confirmed it's a death sentence? If I trim all the dead away, which is the entire crown of the tree, that doesn't leave me with much.

    I'm so heartbroken!

    What's the drainage like in that area? Waterlogged soil in winter/early spring can lead to root death and subsequent top dieback, which would also look similar to those pictures.

    (I cannot rule out verticillium, but equally I don't see anything that proves it.)

    That is actually one of the more dry spots in our yard. Doesn't get too soggy there after a rain. (Thank you for responding!)

    Ok, good to rule out one possibility.

    What part of USA are you from and what climate zone? Might help people to know a little more background, particularly if the problem is specific to your zone.

    We are in Central NC.

    Hardiness zones 6-8.

    Thanks!

    that cross section looks better than I thought. a google image search using verticillium wilt will give several examples of what my untrained eyes were looking for. that also looks like one of the healthier branches though. Are there any viable buds on the branches with no leaves?

    Nope. =( I agree that section doesn't show the "Green" stuff in it, but all the branches leading off that bigger branch were dead. There are no living smaller branches off any of the bigger dead areas. They snap right off and are dry inside. The bigger branch I cut, did still have some moisture inside it. So I'm stumped? It's clear something bad is happening.

    Last year we had a dry summer. By the end of the summer the leaves on the JM looked very sick. I remember commenting to my husband that something was wrong with the tree, we just didn't know what. The leaves had these spots on all of them that made it look like it had chickenpox blisters.

    Shame I did not take any photos at that time.

    Re: Is this Verticillium wilt?

    No, the symptoms shown are not
    Verticillium wilt. The tree would
    already be dead due to an allover
    collapse from the bottom up if this
    tree had the quick decline form of
    Verticillium known as Verticillium
    wilt. There are signs of the branch
    wilt form of Verticillium however.
    Combined with noticeable, allover,
    telltale signs of Tight Bark and also
    suspected internal Pseudomonas
    syringae
    in the plants system (3rd
    photo), there is no choice but to prune
    out all of the deadened and distressed
    limbs back to live, unaffected growth
    nearer the base, lower portion, of the
    tree.

    After a major pruning there may not
    be much of a tree left but by the last
    photo shown there will be enough of
    a tree to build on in the next coming
    years. If you choose to do nothing
    you will most likely lose your tree
    within the next two to three years
    and there is a chance that your tree
    may succumb anyway even after taking
    more controlled steps to induce vigor
    back into this tree. Pruning out as
    much of the infected growth right now
    should restore some vigor back into
    this tree. The question is will there
    be enough vigor left in the tree to
    compensate for the loss of the wood?
    I've seen worse case scenarios and
    have had the tree bounce back to life
    but your time frame to do something
    to help save and rescue this tree is
    quickly diminishing. Time is now
    your enemy.

    So prune it down to the base and hope for the best?

    remove dead wood at any time, I agree that the common symptoms of V Wilt arent obvious and likely is not be present. If you take samples of the plant to your local county extension office they may be able to test it for pathogens etc to help narrow the possibilities of the cause.
