Botrytis on peonies
Hi, sorry if this is a duplicate question, network trouble. 2 photos attached. On the close-up, can you confirm that this is botrytis, or do I need to bring in a sample for analysis? I'm treating it as such, cutting the plants down for fall and disposing of the debris safely. On the second photo, the brown and yellow plants are all peonies, 6 in all. Are they too close together? Do I need to dig some up to make space or can I just cut back some stems in the spring? Thank thou.

Hi, Jill, thanks so much for the quick response! I probably have both varieties of fungus, frankly.
