I acquired a double whit brug NOID in late fall. I tossed it into a pot and it seemed to like it there. Took root and actually grew in a very short time. 👍 It's been housed in the garage along with many other protected plants. since then, never dropping its leaves. But now I see aphids on my otherwise healthy tree. Hints, suggestions?

Can you put together soap and rubbing alcohol in a hole in sprayer and spray the tree. That should kill the aphids. Spray all the trees around it so if they have aphids they wound spread.
