All of my yews at my properties are looking horrible. They are turning a brown starting at the tip and working down the stem. I have talked to quite a few people around here and they are seeing the same thing. It is not spider mites, as they are protected w/Merit and have done some paper test to check for their presence. Many are saying that they think it is from the late frost that we got here. There was new growth when the frost hit and it made them susceptible to some disease. I am going to send some off for testing at the University, but wanted to post some pictures here and see what you guys think. These were taken with my phone, as I didn't plan ahead, but you should see what I am talking about. I was thinking about applying some Heritage to them for the time being to hope to save what I have left of the plants.
