You mentioned rocks discoloring. Do you have a covering of rocks on the top soil that are glued together, if so they should be removed immediately, they are why your trees aren't getting any water.
There is no mention in your post of where you are keeping these junipers, they are not house plants, they should be outside. Unless you live in an arboretum, they won't survive long if you keep them inside.
