My Procumbrens nana Junipers (about 6 of them) came out of the cold frame from this past winter and are a lighter shade of green than they were before. Quite noticeable. All else looks good. No die back or anything. Will they get darker once fertilized and in the sun or is there something else wrong?
Thanks.

Why don't you wait some weeks to see how they evolve in spring?
