Cone Flowers with Aster Yellows or Rosette Mites
Hi there! I sadly just pulled 99% of my cone flowers because they either have Aster Yellows or rosette mite.... I couldn't tell. I have some questions regarding this problem... 1: All the affected flowers were growing in a mess of flowers planted around an old tree stump. This prevents me from getting all the roots and lower foliage of the cone flowers (I did my best). My garden is full of susceptible plants like rudbeckia, daisies, zinnias, and other... How do I prevent the spread without being able to remove all the debris and roots? 2: can I replant coneflowers for next year? Or should I avoid them? 3: How do I tell if my other plants have Aster Yellows? And if the problem was the Rosette Mite, does that affect other perennials? Sorry for the complicated post.... Thanks for your help! My email is firstname.lastname@example.org My phone is 651-900-5471
