Answer: Junipers do not handle heavy pruning, so if you cut back a branch you will then have a bare stub where you cut it. Junipers normally are stiff and self supporting, so I am wondering if yours are possibly in too much shade and becoming weaker as a result. Or, sometimes ice or snow loads can cause a branch to break. (If they are broken you will have to cut them to remove the damaged portion.) You might try a supporting network of twine wrapped in a spiral from top to bottom on the shrubs. You will need to check the twine every month and make sure it is not binding and damaging the bark. I hope this helps.
