I have 344 Blue Rug Junipers planted on the hillside in front of my
house. They were planted 13 years ago. They are quite large and
healthy. The drainage is good and they get enough sun. The problem is
that moss is growing on the lower branches and killing them. This
season, for the first time, some moss is also growing on the exposed
upper branches. I do not know how to attack the moss which is hidden
underneath the branches. Is their a spray which would penetrate the
juniper branches without hurting them and also kill the moss?

I would really appreciate any help that I can get.

Moss likes acid and moisture. Perhaps some lime. Go light and do a
small section first case I am wrong.

Soil test are you below 4.5 ?
