I just finished removing all of our purple coneflowers due to yellow asters. We have rudbeckia in the same garden that appears to not be impacted by the yellow asters, so have left them. We also have chrysanthemum which again, at this time, does not seem to be impacted.
Are rudbeckia and chrysanthemum also susceptible to yellow asters infestation, and as such should be removed as well?
Thanks in advance for your reply.
