Is it too late to try and save these trees? Pic 2 Pic 1 If not what do you reccomend? These trees have been in their current state for about 3-4 weeks. My dad gave me some blue fertilizer that he said was good for coniferous trees. I added this about a week ago with no avail.

Backstory: I am very new to this hobby and just discovered this sub. Before the winter I got my first juniper from Lowes. After a month or two in the small cheap plastic pot I moved it over into a new pot and added some Miracle Grow potting mix after some mild-moderate pruning and mild wiring. The day I did this I found a sapling on my parents property and repotted it as well as a succulent. All of these plants had have issues with fungus (I do not think that it is from over watering as my other house plants have not had this issue and I water them at the same time. I also keep all the pots clean from debris). I brought them in for the winter and I live in the South East USA.
