I have a large pine tree in my backyard that was once a very colorful thriving tree. For some reason, the pine needles are brown and the twigs snap off very easily. I have a pine bush that is starting to show the same signs. I have a few spruce trees that also appear to be dying. I don't know what to do (or not to do).

I was able to make a trip to your home to take a look at your pine tree problem. Once I arrived the pine in question had no live needles and was to far gone to save. I looked at the spruce trees and bushes that you had concern with and find them to be doing very well. As I continued to investigate, I noticed some more pines on the other side of your yard. They had started to show signs of "Chlorosis". This is a tree's inability to produce chlorophyll. This can be caused, but not limited to damaged roots, high alkalinity (base) in the soil, compact roots, or insufficient minerals in the soil. Usually the mineral that is lacking is iron.

I spoke with Diane and found out the tree was at least 10 years old and did have yellow colored needles before it died. This helps to confirm that this was probably the reason for the death of this pine. I would suggest getting a soil sample taken at the still live pine trees location. That would help you narrow down the problem from either soil or root problem. Once that information is gathered a positive course of action can be implemented.
