HELP, we have a tree line in our back yard of 10-foot tall Spartan Junipers.
Following are a couple of close-up pictures of one section of the tree line:

These pictures were taken right after a heavy rain. As you can see, the
tree in the middle of this section of the tree line appears to be
"splitting", where one half of the top branches are hanging to one side, and
theo other half to the other.

Is this normal, or does this signify a problem which needs treatment, for
these kinds of trees? We have frequent high winds, rain, and sometimes ice
storms here in central North Carolina. This tree line has been there for
about 5 years since we moved in this house. We fertilize and water them
regularly with a "soaker hose" buried along the tree line running past the
trunks of all the trees, when they don't get good rain.

She thinks that every time one of these trees shows a section of the
branches near the top hanging out significantly like that after a rain, that
means we need to go out with a ladder and climb up and use coathanger-type
rubber-coated wire to "tie together " the top branches that are hanging out
so they "look regular". She's worried that if they're left untied, and the
branches start sagging out like that after a rain, that they might not "go
back together" when they dry, and could split the tree, and kill the tree,
if all sagging branches aren't immediately tied up with wire after every
rain.

Questions:
1. Is there any basis to the idea that not "wiring up" sagging Spartan
Juniper branches after rains can cause the trees to split and die? (It
hasn't happened yet and we've had these 5 years)

2. Is there any treatment needed for the condition of the trees sagging and
appearing to "split" at the tops after a heavy rain?

3. If this behavior is normal for this kind of tree, how would I explain to
someone that I Don't need to run out and tie these trees up every time they
look like that?

thanks,
- Bobby
