Question
Blue Point Juniper were planted two years ago and are about 6 feet tall. The new growth ( about 3" ) looks very  good in color. The old growth is grey green and the needles appear dry. I water at the perimeter about two time a week for 30 minutes with 4 drip heads per tree. The soil seems to be dry to two feet before I water again.I have fertilized once this year with about a cup per plant. Please advise what you think is happening.

Answer
I would cut back on the water and water once a week with 1 inch of water-place a pan under the tree and turn the sprinkler on and when the pan has 1 inch of water in it stop. Too much water is as bad as too little. If you have not done so mulch around the tree with not more than 3 inches deep of organic mulch (pine straw is good) not piled up on the trunk.

I would fertilize.  For blue spruce, what I would suggest is the following. Use 30-10-10 fertilizer for the growth and use Aluminum Sulphate to help bring out the blue tinge that they are so famous for and the 30-10-10 will grow them nice and healthy. Use 1 lb per inch of trunk diameter scattered around the tree under the foliage. fertilize in the fall and again in the spring and summer.

Or give many of the shrubs, particularly the evergreens, including junipers, a dose of Miracid fertilizer at least twice through the summer.  Miracid is manufactured by Miracle Gro, and in my opinion, Miracid really is a miracle worker with evergreens and other acid loving plants.  Apply early in the spring to all evergreens showing signs of suffering.  Usually results can be seen within two weeks of application.  Results are especially noticeable when applied to Blue Spruce, or other blue-toned shrubs.  Miracid makes them a beautiful steely blue that everyone comments on.
