White fuzzy fungus or mold kill large sections of my pachysandra

Asked June 30, 2015, 1:09 PM EDT

I have had 2 large pachysandra beds for about 35 years and all was fine until about 5 years ago when I noticed an area of about 2 square yards in one of my pachysandra beds that was dying. Closer examination showed patches of white fuzz (dry) along the stems in the affected areas. I dug that section up and sprayed it heavily with a fungicide. That worked well. The disease did not spread and pachysandra filled in the area previously affected. Today I was pulling up some of the pachysandra because it was encroaching on my patio. It looked healthy but I was dismayed to see about 1 square foot of plants with the white fuzz on the stems. I got rid of it quickly before it could portion it could spread and kill my plants. I saw another post describing the same problem. I did take a sample but can't afford the cost of its examination. At least now I know that I had better pay more attention to my normally carefree plants.

The white fluff you see is not killing your pachysandra. The fluff is the protective coating made by plant hopper nymphs, which have minimal to no impact on plants. It washes off in the rain eventually. Here is some info from our website: http://extension.umd.edu/hgic/planthoppers-flowers

Pachysandra has a disease which commonly infects older established plantings. This might be more helpful to you: http://extension.umd.edu/hgic/volutella-dieback-pachysandra-groundcover
