Blue Rug Junipers Dying - Knowledgebase Question

Clermont, NY
Question by khil1535

I have a large area on a sloping piece of ground which has bee filled in beautifully with ten year old blue rug junipers. This year they started dying back; turning brown and just not thriving. I sprayed once with neem but need to know if I must continue the spraying or not. Also, can I prune out the dying and dead branches or leave them on? I am worried about other problems or infections entering through the cuts caused by pruning.

In an established planting there is always reason for concern when die back of any kind occurs. Junipers are occasionally subject to a number of problems ranging from root rot to disease to insect infestation. Unfortunately, based on your description it is impossible to make a diagnosis. You might want to contact your County Extension for a more specific identification of the problem and recommended controls.

You can always prune out truly dead branches, but in this case the pattern may be a clue for daignosing the problem so you might wait until you have done with some certainty before you cut.
