Answer: Junipers are occasionally subject to root rot problems as well as some diseases that could also cause browning. Overwatering or planting in a poorly drained location (or in heavy clay) could all contribute to such problems. Heavy clay can act as a sump and collect water in the hole where the amended soil is less dense, so that is also a possibility. It is also possible that the surface drainage pattern is different between the two planting spots. Improving drainage would involve amending the soil with organic matter and possibly some sand, digging a very generous hole, and possibly planting on a slight rise or better yet, on a slope to avoid runoff collecting around the plant. You might want to consult with the nursery where you purchased the plants since only one of the two is showing any problems, unless you can account for it by differing drainage conditions.
