|aphids are attaching my knockout roses what to use other then a powder product and how often should i use it to destroy the aphids?|
I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
I would spray the roses with insecticidal soap. It is safe and effective it you make sure and contact the insects with the spray.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
