|I purchased several blue star junipers (Monrovia brand, of course) last summer and planted them in several locations in my garden. The new growth comes in nicely (rich silvery blue color). However, some of the older growth does not look so good. The older growth looks light green in color, and on individual needles the tips are yellow, and brown at the very end. Some shoots of the older growth have turned completely brown and have died altogether. I can?t understand how the new growth can look so great and the older growth seems to have some problem. I live in Pittsburgh and the soil has a high clay content. It?s slightly acidic (6.0 ? 6.5) based on my home kit measurements. The weather this summer has been hot and humid. I have not watered much this summer, except for on a couple of occasion where several weeks went by without any natural rainfall. I fertilized a little using the a basic all around shrub fertilizer that I spread on top of the soil. I have a picture that I can send if that would help diagnose the problem. Thanks for your help.
