We planted 7 boxwood about 3 years ago, all except for one look great. One, however, has leaves that are very yellow. These yellow branches seem to be in the middle of the plant. Am I giving it too much water? It does happen to be planted near a water spigot that I hook up to a garden hose to do alot of my watering. The leaves do not seem to be dropping.
I live in Northern California, north of Sacramento, near Grass Valley.
