About 1/2 of my weeping willow tree is bare and looks dead this year. I don't see any army worms or other bugs on it. Not sure why its dieing. I have three other trees that are near by and look healthy
Impossible to tell with info provided. +Pix.
size.. location.. zone.. history of winter weather.. recent planting.. lawn care spraying...
give us anything other than a dead branch if you want us to guess ..
and if you want an answer.. a few pix might get the best result ..
Consider this a good thing...its part of their normal behavoir.
It is true, pics would be very helpful. It might also help to know where you are.
I have a 7-yr-old Weeping Willow (about 25'x 25') that has had a number of problems...so much so, that I'm considering taking it out. My wife and I love the tree, so it is hard to swallow, the prospect of taking it out.
Our willow has been battling Marssonina Leaf Spot, Willow Scab (from what I understand, these two together = Twig Blight). It seemed to be getting through it ok (with a fungicide spray), but in the past two weeks, it's developed a new problem...all the new growth is coming out deformed...not black/brown...just shriveled and deformed...and normal color. I've done a lot of searching on the internet and can't seem to find what the problem is. It also has taken to sprouting new branches from the trunk near the base of the tree.
I'm in the Pacific NW and we've had a cool/wet Spring/Summer. I understand that in the climate I'm in, that these problems, which are fungus-related, can get severe and lead to defoliation and possibly death of the tree. Not knowing where you are and not knowing what the dead and dying parts of the tree look like make it difficult to know what might be the problem.
Please post back with more info and some pics.
