Andromeda Branches Turning Black Though Leaves Look Healthy

Question From: Trenton, New Jersey, United States
Q: What is causing the branches of my Andromeda to turn black? The leaves look healthy but I am concerned about the plant.

A: Could be sooty mold. It grows on honey dew produced by aphids. However I'd take a sample to and independent garden center or nursery for a more accurate ID. Best And Happy Yardening, Nancy
