Question

years old. I have many others but never this trouble

Answer 1

Some diseases, such as juniper tip blight or cedar-apple rust, can cause yellowing and browning of the foliage. These diseases often start in the center of the plant and spread outward

Certain pests, such as spider mites or aphids, can cause yellowing of the foliage. These pests feed on the plant's sap, leading to discoloration and damage.

Yellowing in the center of a juniper can also be a sign of nutrient deficiencies, particularly nitrogen. Junipers require a balanced fertilizer to maintain their health and vibrant green color.
