Around here it can be spring then go right back to winter. The lowest it's gotten was in the lower 20sWhat kind of temps has it been subjected to? I'm not convinced its dead. Also, not familiar w/ MO weather.
it feels the same as it always has, do you mean crunchy as in it easily falls off or in another way.Is it dry/crunchy like @Desert O'Piñon mentioned? If so, I wouldn't hold out much hope. I think it's just winter color.
Great trait for Christmas trees, bad for bonsai.The problem with many conifers, including Juniper, is that by the time you see there's a problem it's often too late. They seem to die from the trunk outwards so by the time the foliage is crispy the whole tree is very dead. What you are seeing now was probably caused several weeks ago, maybe longer. Hard to tell what the cause might be but I'd guess too dry at some stage because of the rapid decline. Most other causes I'm familiar with take longer to kill off a tree.
