I just had to pull out about 15 diseased boxwood plants in the front of my house and in a few other areas. I am looking for a replacement -- the Japanese Holly might be getting the same white powdery blight -- I don't use any harmful chemicals due to the fact that I have raised vegetable garden beds in very close proximity. Any suggestions?
I would have a soil test done before planting to determine if you need to amend you soil.
