I have a new blue star juniper I got a a local bonsai workshop here in the Philadelphia area several months ago. It is turning brown and losing branches not just needles. I have been careful not to overwater it and was told it must be kept outside but that’s when it started looking bad so now I have it inside, hopingI can save it. It does not appear to have insects. I realize this is not enough information to diagnose the problem so I am looking for any advice. Is it true it must be kept outside? A friend said she keeps her similar plants in an unseated garage with no light in winter because it’s dormant. I welcome any opinions on what I should do!
