Damaged pfitzer juniper bushes
We have many different varieties of pfitzers in our yard. Many of these plants have about a foot of dead branches on the tips of the plants this spring. One is completely dead. They are about 20 years old. I have seen many other pfitzers in the city limits of Boulder with the same problem. What is the possible problem?
You are correct about your observations. If you remember, back in first half of November when we had an arctic flow come through, many of the evergreens and shrubs had not moved their sap back into the roots. This arctic freeze caused the freezing sap to damage the weakest parts of the plants.
For the plants with just tip damage, there may be some re-growth. If you cannot see any re-growth, prune back to viable growth.
The following links have publications that provide some information about possible ways to help the plant survive some of our wild weather changes:
