Hello, we recently moved to our house.we have 8 big trees in our backyard and problem started with one of the tree. It started to thin out now we are noticing that all the trees are thinning and it seems like they are dying. We are trying to save them. But don’t have much knowledge how to or who to ask for help.

Your evergreens in the pictures are spruce trees and are declining as most of these do here as they age- there are several diseases and conditions that cause this.
Hire a certified arborist. a professional who has taken training in care, diseases, pests and passed certification tests. The fee is reasonable compared to having to remove and then replace trees. He/she will come on site, walk through your property, and can give a complete diagnosis and a plant care plan. Or can tell you which trees are too far gone and not worth treating.
