Cedar Trees Dying

A gentleman has 2 rows of 4 cedar trees, 2 in one row next to each other have died, slowly over 2 years. Now more are turning brown from the top, down. The trees are given a grass fertilzer, once a year and flood irrigated with well water twice a week. The trees are not in the lawn and nothing has been sprayed around the trees. No weed and feed used on the lawn. The trees are 8-9 years old, transplanted 4 years ago and up until 2 years ago, doing fine.
Suggestions?

Plum Tree Problem

My plum tree has leaves turning black and brown. The stems have a woody look and a grayish in color with some whitish. The stems have turned very woody, dry, brittle leaves curling. I have sprayed the tree with Sevin and at another time even used a fungicide. The fruit is good. I have not made any changes in watering. The ends of the branches are affected. Problem is not on one side of the tree or anything. Any ideas on the problem and treatment?

Wilted leaves

Over half of the leaves on my lilac bush are wilted and curled. I don’t see any evidence of bugs or mold. I just can’t figure out what to do about this. We are watering 3times a week.
