I recently planted 2 Spiral Blue Junipers. they have been in the ground for almost 2 months. About a month now I have noticed that they both begun to brown on the bottom, which now is working its way , it seems to the top. I looked online for several answers but nothing concrete. Any advise or help would be greatly appreciated. I made sure that they have adequate water and put 2 fertilizer sticks in the ground. I attached several photos! Thanks! Mike
