Hi all, I amazingly got this plant to survive the winter. Last year it had a lot of issues (aphids, spider mites (maybe) black spots on leaves). The new growth is curled and deformed, there is a white "dust" on the stems and some leaves. I apply neem oil and copper fungaside alternating between the two on a weekly basis but I can't tell if it's helping. I am a total noob so any help is welcome. I've attached sone pics.
