Q: I planted six foot Oleanders (11) along our fence line approx. 2 wks. ago. They are now infested with aphids. We have been spraying but they continue appear on the plants. What causes them and how do we get rid of them? We live in AZ and this was a large investment for us.
I would spray them with a product called AzaMax according to package directions. It's available at hydroponic stores. It is OMRI listed and environmentally friendly. Best And Happy Yardening, Nancy
