Fairly new to the art, I've got a Jade and 3 Picea Gluca going strong but I'm having issues with my Japanese juniper. The ends of the foliage is turning a dull brown. I live in The 5b usda zone just south of Denver, Colorado,Usa. I was told by the owner of the nursery to not put the little guy outside this winter. I water it once a day typically, and it gets 9 hours of artifical light per day. typically 65-70 degrees with very little humidity. My only thought on why its turning brown is because its inside and warm when it should be dormant. any info would be helpfull!.
