May 15, 1995 pathogenesis in boxwoods consult

May 15, 1995 pathogenesis in boxwoods consult.

This is an outline of etiologies that can individually or can concurrently contribute to pathogenesis in boxwoods.

In my practice as a property manager, landscape designer and horticultural consultant, 1974-1999, I had done a number of boxwood consults.

Boxwoods remain first among equals as to some of my favorite plants. In addition, a 31-foot tall and 22-foot wide Buxus sempervirens on my farm, is a big tree champ in Maryland.

After a consult in 1995, I took it upon myself to compile and loosely organize all my sources into a spiral bound notebook for easy access. This is the result of that file maintenance.

I might add, this information has been compiled and assembled from multiple documented and cited, and undocumented and uncited sources over many-many years – no claim to original authorship is either claimed or implied. If anyone feels there is any breach of copyright, this is not my intent - so please notify me so I can correct the error. May 15, 1995 – April 12, 2014
