Question -
I live in Indiana The evergreens are twenty five years old . One tall evergreen is dead and now my bushes are starting to die. I can't see any bugs. This just started this year. It has been a fairly wet year.

Answer -
Ron,
There are many factors that would cause die back, and death in an evergreen. Most evergreens do not like too much water. Is the soil more clay than loam or sand? Clay soils tend to hold more water, causing the root systems to drown. This is a condition known as wetfeet.
I would recommedn amending the soil using sand and compost to try to improve the drainageand draw the excess water away from the root systems.
Good luck.

Answer
Ron,
You will need to check the soil around the dying plants. If they are composed mostly of clay soil, this will hold more moisture than a sandy (quick draining) or loamy soil (moderate drainage), creating a poor drainage condition that is drowning the roots of the plants. You can tell clay soils by picking some up and pressing it into a ball. If it retains the ball shape, then it is clay. If it starts to crumble slightly, then it is loamy. Sand you should not be able to form into a ball.
You also do not say, or even describe, the types of evergrens that they are. It is also possible that they were attacked by a boring insect, but I cannot diagnose that without a description of teh plants involved.
I hope this cleared up some of your confusion.
