Is this a nectria canker on my trident maple?

[sketchylemons]

I collected this trident maple a couple months back and it was super tall and wouldn't fit in my car so I had to chop it down. It's been rainy since I chopped. I did put some cut paste on it. I went to check in on it and I noticed all those small orange dots. I little research led me to believe it is a fungal infection called a nectria canker. What would some steps be to treat this?

No, I don't think so.

The orange patch on the big cut looks just like orange lichen that is common in these parts. I presume it is also responsible for the coloration of the bark as well.

Generally, lichens are harmless, but I see orange lichen most often on dead forest trees. So, were the trunk in my collection, I might try scrubbing it off with a tooth brush and a peroxide solution (like 2 teaspoon of 3% peroxide from the pharmacy/grocery/hardware store in a quart of water).

Regardless, I don't think you need to worry. Enjoy the holidays.

Thanks for the reassurance. I was skeptical if it was coral spot (some sort of nectria). I put some copper fungicide out of precaution. Maybe that was overkill. Really excited to do some root work, pot this tree up in the spring and start its journey. Got it from a Burkland gardens from Gil down in Mount Vernon for free.

I can see why you would think this is coral spot but I trust Oso

Just chiming in to say I would be tempted not to repot and do root work this spring, you had the opportunity to do rootwork at collection

But to do so after would be a further setback for the tree that could prove fatal

Personally I would wait until at least a year of vigorous growth before carrying out any work, pruning, styling, repotting etc

If the growth is not vigorous next year I would even wait longer

I think it is coral spot nectria canker, see the info of the link below why I think it is.

This is exactly what this deadly fungal infection looks like. In my garden this tree would already be in the restwaste bin (NOT in the compost)

I do not see this as innocent lichens.

I would also be concerned. The coloration looks like it extends to the living tissue below at the cut point. Id try getting your money back and warning the seller to be on the watch.

That’s sad. I’m having a horrible time this last year with something killing off several of my trees.

Right on. I used to live in MV and still have a few trees from Gil.
Have you seen the large weeping Douglas-fir on his property? He also has a Brewer spruce. Both are rare trees.

A clear, closeup picture of the orange bits on your tree would help to confirm what it is.

I am afraid it is infected, the fruiting bodies are clear to see even from not so close.

.you could try nursing it back to health, but @ShimpakuBonsai 's link explains more about it and why you should indeed just trash the tree..

Good thing it was free! (maybe for this reason?)

Let met just add that netria fruiting bodies present in Aug/Sep in this area.

Further, nectria is very easily and most commonly spread by cutting tools. Whatever tools @sketchylemons used to make this trunk chop would have easily infected anything he used them on unless thoroughly sanitized immediately before/after each use. Unfortunately, it won't be obvious if this was the case or not until late next Aug/Sep. IOW, just tossing this trunk out of an abundance of caution wouldn't really solve the problem were this a nectria infection.

When I collected it, it was already in a pot. I just cut the top branches off. Even before I cut the big "leader" branches, the foliage was falling off but seemed healthy. Initial plan was to keep it in the pot until spring. The soil its in right now doesn't appear to be the best but I think waiting for vigorous growth is a good idea.

I got this for free, so my wallet isn't bummed out rather my excitement for obtaining raw material.

I used a nurseryman's saw at a nursery to cut the tree. If I remember correctly, it was not really clean.

Whether or not this is nectria, be mindful of where the advice you're given is coming from.

Is it coming from someone with actual experience, who deals with the same things, in the same climate as you?
These things matter.

You're correct. I'm in Bellingham and the people within 40 miles from me are saying it's either lichen or not fruiting bodies. Everyone else is giving convoluted advice. All is appreciated but I think in this case, location is very important to consider.

Not sure if this is a result of using a dirty nursery saw when I picked up the tree. Either way, I know to be really careful with clean tools from now on.
