Hello,
Last year was year 2 for my black eyed Susans and they spread rapidly, but with all of the rain last summer they quickly became diseased with powdery mildew and attacked by pests. I cleared out the black eyed Susans last fall rather than leaving the dead foliage over winter since the plants were diseased. This year the black eyed Susans have started to come back, but I noticed that they are already diseased and being attacked by pests. I am going to pull the diseased ones, but is there any hope for new seedlings that might pop up? Is there something I can do to prevent them from being diseased? Or is it an issue with the soil or the seeds themselves that can’t be resolved? Thanks in advance!
