I’m not an expert, but I want to say this is normal. Young trees will build some resistance to some types of normal bacteria and fungus overtime. I wouldn’t sweat it until the whole trees sees some overall decline. Wait until next spring/summer and see if it outgrows the discoloration. I think this coloration is common for this time of year.

It looks like sooty mold on stem and branches , common for trees coming from Florida.

Thanks everyone for the replies. Would a general fungal treatment be a good idea or no worries. I just set up my Greenhouse and dont want to bring the 2 plant o gram trees in with my spykes trees which are doing amazingly well.

One of solutions is to use horticultural oil or neem oil (Spray on tree and foliage) during non-sunny conditions.

What good is oil going to do?  I dont recommend oil at all.

@bsbullie what do you reccomend?

If its anthracnose, you cant make it go away.  You can only spray to prevent it.  Either copper or abound if spraying.  I dont spray anything on my trees.

Neem oil is a fungicide.

Neem oil is a fungicide.

Neem causes more harm than good here.

What bsbullie said, Neem oil if not constantly mixed while spraying will burn young leaves. I learned the hard way after burning my CC leaves, it took a while for the CC to recover. Those black spots should disappear in a few months if the tree is kept outdoor with good airflow.

I guess we should ask Rob...do you think this is sooty mold or anthracnose?
I thought it was sooty mold.  I’m kind of embarrassed to say that when I received trees from Florida with this condition, I actually carefully used diluted bleach and a small brush to scrub off the black sooty mold....I’m probably lucky I didn’t kill my mango treeS doing this.
