I have some Wichita Blue junipers which are showing dying branches (just go very pale brown).* The plants are in full sun or part shade, are getting a sufficient amount of water but not excessive.* I don't see any bugs or webs.* Had quite a bit of die-off after a dry and windy winter, trimmed the plants back, but now it's coming back.* Could it be a Ph problem?* The online sources I've seen say junipers have a wide tolerance.* Our soil is a little acid, but these plants are not far from concrete walls.
