My trees look sick.

Asked January 14, 2019, 11:21 AM EST

We have 11 very large spruce trees that we transplanted 35 years ago. They are 35-40 feet tall now. We have noticed in the last year spots of dead needles. It is now all the trees. Some are just spots and some is whole sections. I am hoping you can help us save our trees. Thanks

I can't tell what may be going on with your spruce from your photos. The symptoms (browning needles) can be due to environmental conditions (too hot, dry or wet), insects or diseases : needlecasts, tip blights and canker diseases.

Here are a couple of links that may help you identify the problem –
