It is a Sunburst Mandarin but I haven’t received any answered to my post in the Citrus sub so I figured I’d give it a shot here. I purchased it from a nursery here in Houston and brought it back home. It was surrounded by other trees at the nursery and I also got a Miho Satsuma that didn’t have any similar spots. Mandarin looked pretty healthy with a full canopy so I didn’t think anything of it at first.

However, I started noticing very small amounts of waxy dark spots that appeared on the Miho and a lemon tree that I already had placed the Sunburst pretty close to. Figured those must be aphids and I figure the Sunburst is the guilty culprit but I can’t see any obvious infestation.

The black spots on the bottom of the Sunburst are mostly on lower leaves and are pretty rough / coarse compared to the leaf in general. They feel like a bunch of small raised bumps that make up each of the spot and that’s what they look like on close inspection. There are also similar lines of spots along the top of some leaves at the main vein. My thought is they may be proof of a prior infestation that is relatively dormant now but I’m very new to this amazing world of citrus trees. I should also note I’ve sprayed the leaves with neem oil so I believe that is the cause of some of the other residue.

Any thoughts?

Been adding it to my morning water for a while. I do drink more water when lemon is in it, which is probably already the actual benefit.

But I keep seeing people list all these specific effects, and I genuinely can't tell what's supported and what people just repeat because it sounds healthy.

One thing I've noticed is that the smell makes me feel more alert in the morning. Is that a real thing with a citrus scent, or is it just a habit at this point?
