It’s an odd shape. Has it had its top cut off? I suspect so. And probably the cut has become infected by a fungus and that’s what is causing the dieback.No point in waiting for the poor thing to spring to life. It’s beyond hope.
In the wild they grow on well drained hillsides, often in full sun. So are ok with fairly dry conditions. If anything it might have been too wet over winter, judging by what seems to be around its base?But it is an odd shape for a juniper, so is it some special dwarf weeping variety? Unfortunately I think it is unlikely ever to recover its full beauty so I hope it didn’t cost you too much.
