I moved the Philodendron Xanadu to the front porch of my house which is enclosed and it is doing much better and I will move it indoors completely soon. It gets tiny aphids mainly on the back of the leaves. I have sprayed it with a house plant pest spray containing fatty acids its (been in the garage a long time perhaps it’s gone off.”)as they seem to keep coming back. Can you reccommend a treatment please?
