Double knockout roses doing poorly Help!
Hello group! I planted 5 double KO rose bushes in April 07,
they did wonderful! I cut them back in Feb.08 they were doing great and produced many buds in March but..they were covered with aphids I treated with organic pesticide which did not touch them so I treated with a systemic pesticide,after two treatments the aphids seemed to be under control within a week (this was two weeks ago) the leaves started turning yellow with brown spots and falling off so i treated with a systemic fungicide there is new growth on only two plants, my question is should I go ahead and cut them back again? as you can imagine they look awful I would send a picture but I cannot figure out how to do that. Thanks Debbie
